Mate Interface Cables

The 1-Port OC-192/STM-64 POS/RPR XFP SPA supports two mate interface configurations:

Mate between two OC-192c SPAs in the same SIP
Mate between two OC-192c 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. The following figure shows the mate cables used to connect the SPAs.


1	Long length RPR mate cable for single port RPR SPAs (CBL-RPR-OC192-L)	2	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 using SPA datasheets or by contacting your Cisco representative.

Cisco Systems qualifies the optics that are approved for use with its SPAs. The following OC-3 optical transceiver modules are supported on the 8-Port OC-3/STM-1 POS SPA:

Multimode (MM) SFP module—SFP-OC3-MM
Short-reach (SR) SFP module—SFP-OC3-SR
Intermediate-reach (IR) SFP module (15 km)—SFP-OC3-IR1
Long-reach (LR) SFP module (40 km)—SFP-OC3-LR1
Long-reach (LR) SFP module (80 km)—SFP-OC3-LR2

The following OC-3 optical fiber options are available for the 8-Port OC-3/STM-1 POS SPA:

Multimode—155.52-Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1)

Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.

Single-mode—155.52-Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1)

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.)

For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see the below figure) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).

Use single-mode (for short-, intermediate- or long-reach configurations) or multimode optical fiber cable to connect your router to a network or two OC-3-equipped or OC-12-equipped routers back-to-back.

Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between them.

RJ-45 Cable Pinouts

T1 lines from individual subscribers are attached to the 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 CEoP SPAs to each other, you must cable both the SPA’s patch panels together using a T1 crossover cable or a T1 straight through cable. The type of cable you use (crossover or straight through) depends on how the CEoP SPAs are cabled to their patch panels:

If both the 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 crossover cable to connect the patch panels to each other.
If both the 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.
