Checking Hardware and Software Compatibility
To check the minimum software requirements of Cisco IOS XR software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether SIPs or SPAs within a system are compatible, but it does provide the minimum Cisco IOS XR requirements for individual hardware modules or components.
Note Access to this tool is limited to users with Cisco.com login accounts.
To access Software Advisor, click Login at Cisco.com, type “Software Advisor” in the SEARCH box, and click GO. Click the link for the Software Advisor tool.
Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.
Bandwidth Oversubscription
Oversubscribing the bandwidth limit recommendations of a router can result in decreased or degraded performance. For this reason, it is important to determine the amount of bandwidth used by the SPAs on the router and verify that the total bandwidth used by all SPAs does not exceed the recommended bandwidth limit of the router. The aggregate throughput should not exceed 2 full-rate SPAs for 10G SIPs.
Note The SIP-600 [10G SIP], SIP-401 [2.5G SIP], SIP-501 [5G SIP], and SIP-601 [10G SIP] can support up to 20G of installed SPAs, but the bandwidth through the engine and the fabric is no more than 10G (SIP-600 or SIP-601). The bandwidth through the engine and the fabric is no more than 5G for the SIP-501 and is no more than 2.5G for the SIP-401.
Note In Cisco IOS XR software release 3.9.1 or prior, the full-rate SPAs need to be positioned in bay 0 and 1.
Table 2-2 provides information about the bandwidth for each port (per-port bandwidth) on a SPA, as well as the cumulative bandwidth (total bandwidth) for all ports available on the SPA.

2-Port and 4-Port Clear Channel T3/E3 SPA Interface Specifications
The framer processes incoming and outgoing T3 (cbit, m13/m23, and unframe) and E3 (g751, g832, and unframe) frames. The framer operates at T3/E3 line rates (44.736 /34.368 Mbps) depending on the mode in which it is configured.
Packet data is transported with a user-configurable encapsulation (such as Point-to-Point Protocol [PPP] or High-Level Data Link Control [HDLC]), and is mapped to T3 and E3 frames. The encapsulations add transport overhead to the packet of data frames before transporting, and are stripped when a packet is transported to the far end.
The T3/E3 SPA interface is compliant with ANSI and Telco standards. The interface also provides support for Management Information Base (MIB) RFC 2496 and T1.231.
2-Port and 4-Port Clear Channel T3/E3 SPA Cables and Connectors
The interface connectors on the 2-Port and 4-Port Clear Channel T3/E3 SPA are 75-ohm coaxial Siemax types, with one connector and cable for transmit (TX) and one for receive (RX).
The following cables can be used with the 2-Port and 4-Port Clear Channel T3/E3 SPA. The cables have BNC connectors on one end and the Siemax connectors on the other. If similar SPAs are connected back-to-back, both ends of cable will be Siemax.
- CAB-T3E3-RF-BNC-M (T3 or E3 Cable, 1.0/2.3 RF to BNC-Male, 10 feet)
- CAB-T3E3-RF-BNC-F (T3 or E3 Cable, 1.0/2.3 RF to BNC-Female, 10 feet)

8-Port Channelized T1/E1 SPA Interface Specifications
The E1 interface on the 8-Port Channelized T1/E1 SPA uses RJ-48c receptacles for E1 (120-Ohm) cables with RJ-45 connectors. You can use all ports simultaneously. Each E1 connection supports interfaces that meet G.703 standards. The RJ-45 connection does not require an external transceiver. The E1 ports are E1 interfaces that use 120-ohm shielded twisted pair (STP) cables.
Warning Shielded twisted pair (STP) T1/E1 cables must be used to comply with EN55022/CISPR22 Class A emissions requirements. For revisions 73-8358-05 through 73-8358-08 Shielded Twisted pair (STP) T1/E1 cables must be used to comply with FCC Class A emissions requirements.
8-Port Channelized T1/E1 SPA Cables, Connectors, and Pinouts
Figure 2-4 shows an RJ-45 connector.
Note The terms RJ-45 and RJ-48c are sometimes used interchangeably. The RJ-48c is the jack or receptacle; the RJ-45 is the connector.

8-Port FastEthernet SPA Cables, Connectors, and Pinouts
The interface connectors on the 8-Port FastEthernet SPA are eight individual RJ-45 receptacles. You can use all eight interface connectors simultaneously. Each connection supports IEEE 802.3 and Ethernet 10/100BASE-T interfaces compliant with appropriate standards. Cisco Systems does not supply Category 5 unshielded twisted-pair (UTP) RJ-45 cables; these cables are available commercially.
Figure 2-6 shows the RJ-45 connector.
Figure 2-6 RJ-45 Connections, Plug, and Receptacle
Table 2-10 lists the pinouts and signals for the RJ-45 connector.

Note Referring to the RJ-45 pinout in Table 2-10, proper common-mode line terminations should be used for the unused Category 5 UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45 port circuitry in the 8-Port FastEthernet SPA.
The 8-Port FastEthernet SPA supports automatic MDI/MDIX crossover at all speeds of operation allowing the SPA to work with straight-through and crossover Ethernet cables. Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure 2-7 and Figure 2-8.

1-Port 10-Gigabit Ethernet SPA XFP Optical Transceiver Modules, Connectors, and Cables
The 1-Port 10-Gigabit Ethernet SPA supports the following types of optical transceiver modules:
- Single-mode short-reach (SR) XFP module—XFP-10GLR-OC192SR
- Single-mode intermediate-reach (IR) XFP module—XFP-10GER-OC192IR
- Single-mode very-long-reach (ZR) XFP module—XFP-10GER-OC192LR
- Multi-mode short reach (SR) XFP module—XFP-10G-MM-SR
Cisco Systems qualifies the optics that are approved for use with its SPAs. As of Cisco IOS XR Release 3.4.1, the above-listed small form-factor pluggable (XFPs) are the only optical transceiver modules qualified for use.
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns (nominal diameter is approximately 10/125 microns) to connect your router to a network.
Figure 2-10 shows the cable type for use with the XFP optical transceiver module on the 1-Port 10-Gigabit Ethernet SPA.
Figure 2-10 LC-Type Cable for the XFP Optical Transceiver Modules
Note The 40-pin connector on the 1-Port 10-Gigabit Ethernet SPA is used for resilient packet ring (RPR) connections. This feature is not supported in Cisco IOS XR Release 4.3.0.
XFP Connections
The 10GLR, 10GER, and 10GZR XFP modules include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits. The XFP modules provide high-speed serial links at the rate of 10.3125 Gbps (10 Gigabit Ethernet) on single-mode fiber (SMF). The transmit side recovers and retimes the 10-Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310-nm, 850 nm or 155-nm laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a photo detector transimpedance amplifier and passes it to an output driver.
See the label on the XFP module for technology type and model. Figure 2-11 shows an XFP module and Table 2-12 shows the XFP module specifications.
Figure 2-11 XFP Module
XFP module dimensions are:
- Height: 12.5 mm
- Width: 18.35 mm

The valid configuration of the SFP ports for the 2-Port Gigabit Ethernet SPA (Version 2) is Port 0 (SFP) and Port 1 (SFP), or any single port.
Note The 2-Port Gigabit Ethernet SPA has two RJ-45 ports. However, these RJ-45 ports are not supported by the Cisco XR 12000 Series Router.
2-Port Gigabit Ethernet SPA Cables and Connectors
The interface connectors on the 2-Port Gigabit Ethernet SPA are two individual fiber-optic receivers that support SFP modules. Each port can send and receive traffic using the optical fiber connections.
SFP Module Connections
The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the Gigabit Ethernet ports on the 2-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
Note The 2-Port Gigabit Ethernet SPA will only accept the SFP modules listed as supported in this document. An SFP module check is run every time an SFP module is inserted into the 2-Port Gigabit Ethernet SPA and only SFP modules that pass this check will be usable by the 2-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 2-Port Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug into the 2-Port Gigabit Ethernet SPA ports.
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface. Table 2-16 and Table 2-17 provide SFP module information and specifications.

Supply voltage range |
SFP-GE-S: 3.1 to 3.5 V SFP-GE-L: 3.1 to 3.5 V SFP-GE-Z: 3.1 to 3.5 V |
SFP-GE-S Modules
The 1000BASE-SX (short wavelength) module operates on standard multimode fiber-optic link spans of up to 500 m on 50/125um MMF and 300 m on 62.5/125um MMF.
SFP-GE-L Modules
The 1000BASE-LX/LH (long wavelength/long haul) module interfaces fully comply with the
IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.
SFP-GE-Z Modules
The 1000BASE-ZX (extended wavelength) module operates on ordinary single-mode fiber-optic link spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber (premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion).
The 1000BASE-ZX module must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The 1000BASE-ZX module will not operate correctly when coupled to multimode fiber, and it is not intended to be used in environments where multimode fiber is frequently used (for example, building backbones, or horizontal cabling).
The 1000BASE-ZX module is intended to be used as a Physical Medium Dependent (PMD) component for Gigabit Ethernet interfaces found on various switch and router products. It operates at a signaling rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.
When shorter lengths of single-mode fiber are used, it may be necessary to insert an in-line optical attenuator in the link to avoid overloading the receiver.
- Insert a 10-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).
- Insert a 5-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is equal to or greater than 15.5 miles (25 km) but less than 31 miles (50 km).
SFP-GE-T Modules
The SFP-GE-T (1000BASE-T copper SFP module) provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over an existing copper network infrastructure. The SFP-GE-T maximum cabling distance is 328 feet (100 m).
SFP Module Cabling and Connection Equipment
Table 2-18 provides cabling specifications for the SFP modules that can be installed on the 2-Port Gigabit Ethernet SPA. Note that all SFP ports have LC-type connectors.
The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).

You should measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed with a 1550-nm light source.

SFP-GE-S: 3.1 to 3.5 V SFP-GE-L: 3.1 to 3.5 V SFP-GE-Z: 3.1 to 3.5 V |
SFP-GE-S Modules
The 1000BASE-SX (short-wavelength) module operates on standard multimode fiber-optic link spans of up to 500 m on 50/125um multimode fiber (MMF) and 300 m on 62.5/125um MMF.
SFP-GE-L Modules
The 1000BASE-LX/LH (long-wavelength/long-haul) module interfaces fully comply with the
IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.
SFP-GE-Z Modules
The 1000BASE-ZX (extended-wavelength) module operates on ordinary single-mode fiber-optic link spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. (Premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion.)
The 1000BASE-ZX module must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The 1000BASE-ZX module does not operate correctly when coupled to multimode fiber, and it is not intended to be used in environments in which multimode fiber is frequently used (for example, building backbones or horizontal cabling).
The 1000BASE-ZX module is intended to be used as a Physical Medium Dependent (PMD) component for Gigabit Ethernet interfaces found on various switch and router products. It operates at a signaling rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.
When shorter lengths of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. Use the following guidelines:
- Insert a 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).
- Insert a 5-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is equal to or greater than 15.5 miles (25 km) but less than 31 miles (50 km).
SFP Module Cabling and Connection Equipment
Table 2-26 provides cabling specifications for the SFP modules that can be installed on the 10-Port Gigabit Ethernet SPA. Note that all SFP ports have LC-type connectors.
The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).

Note The 1000BASE-ZX SFP modules provide an optical power budget of 21.5 dB. You should measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed with a 1550-nm light source.

Mate Interface Cables
The 1-Port OC-192/STM-64 POS/RPR SPA supports two mate interface configurations:
- Mate between two OC-192 SPAs in the same SIP
- Mate between two OC-192 SPAs in adjacent SIPs
Two 1-Port OC-192/STM-64 POS/RPR SPAs are connected using a 40–pin connector copper mate cable. The length of the cables allow only two possible connection scenarios, next slot horizontal and same slot vertical. This assumes that the chassis is mounted vertically. Figure 2-27 shows the mate cables used to connect the SPAs.

|
Long length RPR mate cable for single port RPR SPAs (CBL-RPR-OC192-L) |
|
Short length RPR mate cable for single port RPR SPAs (CAB-RPR-OC192-S) |
Note The RPR mate cable is necessary only when the SPA is to be used in RPR mode. It is not needed in POS mode. Support for the RPR feature is dependent on the platform software release feature content. Verify support for the RPR feature support by reviewing the relevant SPA datasheets or by contacting your Cisco representative.

The 1-Port OC-192/STM-64 POS/RPR XFP SPA supports the following types of optical transceiver module:
- Single-mode short-reach (SR) XFP module—XFP-10GLR-OC192SR
- Single-mode intermediate-reach (IR) XFP module—XFP-10GER-OC192IR
- Single-mode very-long reach XFP module—XFP-10GZR-OC192LR
Cisco Systems qualifies the optics that are approved for use with its SPAs. As of Cisco IOS XR Software Release 3.4.0, the above-listed XFPs are the only optical transceiver modules qualified for use.
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns (nominal diameter is approximately 10/125 microns) to connect your router to a network.
Figure 2-29 shows the cable type for use with the XFP optical transceiver module on the 1-Port OC-192/STM-64 POS/RPR XFP SPA.

Mate Interface Cables
The 1-Port OC-192/STM-64 POS/RPR XFP SPA supports two mate interface configurations:
- Mate between two OC-192 SPAs in the same SIP
- Mate between two OC-192 SPAs in adjacent SIPs
Two 1-Port OC-192/STM-64 POS/RPR XFP SPAs are connected using a 40–pin connector copper mate cable. The length of the cables allow only two possible connection scenarios, next slot horizontal and same slot vertical. This assumes that the chassis is mounted vertically. Figure 2-30 shows the mate cables used to connect the SPAs.

Long length RPR mate cable for single port RPR SPAs (CBL-RPR-OC192-L) |
|
Short length RPR mate cable for single port RPR SPAs (CAB-RPR-OC192-S) |
Note The RPR mate cable is necessary only when the SPA is to be used in RPR mode. It is not needed in POS mode. Support for the RPR feature is dependent on the platform software release feature content. Verify support for the RPR feature support via SPA datasheets or by contacting your Cisco representative.
4-Port OC-3/STM-1 POS SPA Overview
The 2-Port and 4-Port OC-3/STM-1 POS SPA is a single-height SPA that installs into one SIP subslot. The OC-3c/STM-1 POS SPA with small form-factor pluggable (SFP) optical transceiver modules provides SONET and SDH network connectivity with a per-port bandwidth of 155.52 Mbps.

1-Port OC-48/STM-16 POS SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-48/STM-64 line rates (9.95 Gbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]) and is mapped into the STS-48/STM-64 frame.
The 1-Port OC-48/STM-16 POS SPA interface is compliant with the following RFCs:
- RFC 1662, PPP in HDLC-like Framing
- RFC 2615, PPP over SONET/SDH
1-Port OC-48/STM-16 POS SPA Optical Transceiver Modules, Connectors, and Cables
The 1-Port OC-48/STM-16 POS SPA uses a single-mode, 9.95 Gbps, OC-48 optical fiber (SONET STS-48) optical transceiver module for SONET connection to the network.
The 1-Port OC-48/STM-16 POS SPA supports the following type of optical transceiver module:
- Single-mode short reach (SR) SFP module—SFP-OC48-SROC-48/STM-16c
- Single-mode intermediate reach (IR) SFP module—SFP-OC48-IR1OC-48/STM-16c
- Single-mode long reach (LR) SFP module—SFP-OC48-LR2OC-48/STM-16c
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns (nominal diameter is approximately 10/125 microns) to connect your router to a network.
Figure 2-41 shows the cable type for use with the XFP optical transceiver module on the 1-Port OC-48/STM-16 POS SPA.
Figure 2-41 LC-Type Cable for the SFP Optical Transceiver Modules
Note The 40-pin connector on the 1-Port OC-48/STM-16 POS SPA is used for resilient packet ring (RPR) connections.
Mate Interface Cables
The 1-Port OC-48/STM-16 POS SPA supports two mate interface configurations:
- Mate between two OC-48 SPAs in the same SIP
- Mate between two OC-48 SPAs in adjacent SIPs
Two 1-Port OC-48/STM-16 POS SPAs are connected using a 40–pin connector copper mate cable. The length of the cables allow only two possible connection scenarios, next slot horizontal and same slot vertical. This assumes that the chassis is mounted vertically. Figure 2-42 shows the mate cables used to connect the SPAs.

The framer processes incoming and outgoing T3 (cbit, m13/m23, and unframe) and E3 (g751 and unframe) frames. The framer operates at T3 or E3 line rates (44.736 or 34.368 Mbps), depending on the mode in which it is configured.
Note For Cisco IOS XR Software Release 3.7.0, the 2-Port Channelized T3/E3 ATM CEoP SPA supports T3 ATM only. E3 ATM is not supported.
T3/E3 data is encapsulated and sent across the MPLS network over user-configurable pseudowires. In ATM mode, data is encapsulated into ATM cells and transported across the network.
In circuit emulation (CE) mode, channelized data is encapsulated in structured mode using the Circuit Emulation Services over Packet Switched Network (CESoPSN) format, and unchannelized data is encapsulated in unstructured mode using Structure-Agnostic TDM over Packet (SAToP) format. The encapsulation adds transport overhead to the CEM frames or ATM cells before transport and removes the overhead at the far end.
Note For Cisco IOS XR Software Release 3.7.0, the 2-Port Channelized T3/E3 ATM CEoP SPA does not support circuit emulation (CE) mode.
The T3/E3 SPA interface is compliant with ANSI and Telco standards. The interface also provides support for Management Information Base (MIB) RFC 2495, RFC 2496, and T1.231.
2-Port Channelized T3/E3 ATM CEoP SPA Cables and Connectors
The interface connectors on the 2-Port Channelized T3/E3 ATM CEoP SPA are 75-ohm coaxial Siemax types, with one connector and cable for transmit (TX) and one for receive (RX).
The following cables can be used with the 2-Port Channelized T3/E3 ATM CEoP SPA. The cables have BNC connectors on one end and the Siemax connectors on the other. If similar SPAs are connected back-to-back, both ends of the cable are Siemax.

RJ-45 Cable Pinouts
T1 lines from individual subscribers are attached to RJ-45 connectors on the front of the 24-port patch panel. Each RJ-45 port accommodates an individual T1 subscriber line.
Pins 1 and 2 and 4 and 5 of the RJ-45 connectors are used for the 24-port CEoP SPA’s Transmit (TX) and Receive (RX) signals. Depending on how the cable is installed between the SPA and its patch panel (rear), the RJ-45 connectors operate as follows:
- If the TX cable lead is connected to Transmit on the patch panel and RX is connected to Receive:
– The SPA’s TX signals are transmitted on RJ-45 pins 1 (ring) and 2 (tip).
– The SPA’s RX signals are received on RJ-45 pins 4 (ring) and 5 (tip).
- If the TX cable lead is connected to Receive on the patch panel and RX is connected to Transmit:
– RJ-45 pins 1 and 2 are used for the SPA’s RX signal.
– RJ-45 pins 4 and 5 are used for the SPA’s TX signal.
Patch Panel Cabling
If you are connecting two 24-Port Channelized T1/E1/J1 ATM CEoP SPAs to each other, you must cable both SPA’s patch panels together using a T1 cross-over cable or a T1 straight-through cable. The type of cable you use (cross-over or straight-through) depends on how the CEoP SPAs are cabled to their patch panels:
- If both CEoP SPAs are connected to their patch panels in the same manner (TX to Transmit and RX to Receive, or TX to Receive and RX to Transmit), use a T1 cross-over cable to connect the patch panels to each other.
- If both CEoP SPAs are connected to their patch panels in a different configuration (TX to Transmit and RX to Receive on one SPA, and TX to Receive and RX to Transmit on the other SPA), use a T1 straight-through cable (standard RJ-45 patch cable) between the patch panels.

Figure 2-63 LC-Type Cable for the XFP Optical Transceiver Modules
XFP Module Connections
The 10GLR, 10GER, and 10GZR XFP modules include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits. The XFP modules provide high-speed serial links at the rate of 10.3125 Gbps (10-Gigabit Ethernet LAN PHY mode) and 9.95328 Gbps (10-Gigabit Ethernet WAN PHY mode) on single-mode fibers (SMF). The transmit side recovers and retimes the 10-Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310-nm or 1550-nm laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a photo detector transimpedance amplifier and passes it to an output driver.
See the label on the XFP module for the technology type and model. Figure 2-64 shows an XFP module and Table 2-53 shows the XFP module specifications.
