The following table lists the Cisco Transport Controller (CTC) software compatibility for the ROADM cards.

ROADM cards are designed for use with specific channels in the C band and L band. In most cases, the channels for these cards are either numbered (for example, 1 to 32 or 1 to 40) or delimited (odd or even). Client interfaces must comply with these channel assignments to be compatible with the ONS 15454 system.

The following cards operate in the C-band:

• 32WSS

• 32DMX

• 32DMX-C

• 40-MUX-C

• 40-WXC-C

• 80-WXC-C

• 40-SMR1-C

• 40-SMR2-C

• MMU

The following add drop cards utilize the L-band DWDM channels:

• 32WSS-L

• 32DMX-L

Table 1 lists the L-band channel IDs and wavelengths at ITU-T 50-GHz intervals. This is a comprehensive L-band channel table that encompasses present and future card capabilities.

The two-slot 32-Channel Wavelength Selective Switch (32WSS) and 32-Channel Wavelength Selective Switch L-Band (32WSS-L) cards perform channel add/drop processing within the DWDM node. The 32WSS or 32WSS-L card can be installed in the following pairs of slots:

• Slots 1 and 2

• Slots 3 and 4

• Slots 5 and 6

• Slots 12 and 13

• Slots 14 and 15

• Slots 16 and 17

The 32WSS or 32WSS-L cards has six types of ports:

• ADD RX ports (1 to 32): These ports are used for adding channels (listed in Table 1 or Table 2). Each add channel is associated with an individual switch element that selects whether that channel is added. Each add port has optical power regulation provided by a variable optical attenuator (VOA). The 32WSS has four physical receive connectors that accept multifiber push-on (MPO) cables on its front panel for the client input interfaces. Each MPO cable breaks out into eight separate cables.

• EXP RX port: The EXP RX port receives an optical signal from another 32WSS card in the same network element (NE).

• EXP TX port: The EXP TX port sends an optical signal to the other 32WSS card within the NE.

• COM TX port: The COM TX (line input) port sends an aggregate optical signal to a booster amplifier card (for example, OPT-BST) for transmission outside of the NE.

• COM RX port: The COM RX port receives the optical signal from a preamplifier (such as the OPT-PRE) and sends it to the optical splitter.

• DROP TX port: The DROP TX port sends the split-off optical signal containing drop channels to the 32DMX card, where the channels are further processed and dropped.

Aggregate optical signals that enter the EXP RX and COM RX port are processed in two ways:

• EXP RX Port Add Channel/Pass-through Processing

  The incoming optical signal is received at the EXP RX port from the other 32WSS card within the NE. The incoming aggregate optical signal is demultiplexed into 32 individual wavelengths, or channels. Each channel is then individually processed by the optical switch, which performs add/pass-through processing. By using software controls, the switch either selects the optical channel coming in from the demultiplexer (that is, the pass-through channel) or it selects the external ADD channel. If the ADD port channel is selected this channel is transmitted and the optical signal coming from the demultiplexer is blocked.

  After the optical switch stage, all of the channels are multiplexed into an aggregate optical signal, which is sent out on the COM TX port. The output is typically connected to an OPT-AMP-L or OPT-BST-E card (in the event a booster amplifier is needed) or to an OSC-CSM card (if no amplification is needed).

• COM RX Port Optical Splitter Processing

  The COM RX port receives the incoming optical signal and directs it to the 32WSS card’s optical splitter. The splitter optically diverts channels that are designated to be dropped to the DROP TX port. The DROP TX port is typically connected to the COM RX port of the 32DMX where the drop channels are being dropped. Channels that are not dropped pass-through the optical splitter and flow out of the 32WSS card EXP TX port. Typically, this optical signal is connected to the other 32WSS module within the NE.

The COM TX value can be measured by either a physical or a virtual photodiode of the 32WSS card. If the vendor ID of the 32WSS card is between 1024 (0x400) and 2047 (0x800) the COM TX value is measured by physical photodiode. If the vendor ID of the 32WSS card is greater than 2048 (0x800), the COM TX value is measured by the virtual photodiode. For COM TX values measured by virtual photodiode, check the values at the RX port in the downstream of the COM TX port (COM-RX port on OPT-BST or OSC-CSM card).

The single-slot 32-channel demultiplexer (32DMX) or the 32-channel demultiplexer L-band (32DMX-L) card is an optical demultiplexer. The card receives an aggregate optical signal on its COM RX port and demultiplexes it into to (32) ITU-T 100-GHz-spaced channels. The 32DMX or 32DMX-L card can be installed in Slots 1 to 6 and in Slots 12 to 17. The 32DMX-L card is particularly well suited for use in networks that employ DS fiber or SMF-28 single-mode fiber.

The 32DMX or 32DMX-L card has two types of ports:

• COM RX port: COM RX is the input port for the aggregate optical signal being demultiplexed. This port is supported by a VOA for optical power regulation and a photodiode for optical power monitoring.

• DROP TX ports (1 to 32): On its output, the 32DMX provides 32 drop ports that are typically used for dropping channels within the ROADM node. These ports are connected using four 8-fiber MPO ribbon connectors. The incoming optical signal to the demultiplexer comes into the COM RX port. This input port is connected using a single LC duplex optical connector. Each drop port has a photodiode for optical power monitoring. Unlike the two-slot 32DMX-O demultiplexer, the drop ports on the 32DMX do not have a VOA per channel for optical power regulation.

The double-slot 80-channel Wavelength Cross-Connect C-band (80-WXC-C) card manages up to 80 ITU-T 50 GHz-spaced channels identified in the channel plan and sends them to dedicated output ports. Each channel can be selected from any input port to any output port. The card is optically passive, and provides bidirectional capability. It can be installed in Slots 1 to 5 and 12 to 16 the ONS 15454 chassis. It can be installed in Slots 2 to 6 in the Cisco ONS 15454 M6 and Slots 2 to 17 in the NCS 2015 chassis.

The 80-WXC-C card provides the following functionalities:

• When used in the multiplexer or bidirectional mode, the 80-WXC-C card allows selection of a single wavelength or any combination of wavelengths from any of the nine input ports to the common output port.

• When used in the bidirectional mode, the output wavelength from the COM-RX port is split to manage the express and drop wavelengths.

• When used in the demultiplexer mode, the 80-WXC-C card, allows selection of a single wavelength or a combination of wavelengths from the common input port to any of the nine output ports.

• Automatic VOA shutdown (AVS) blocking state on each wavelength and port.

• Per-channel (closed loop) power regulation on the output port based on OCM block feedback.

• Per-channel (open loop) attenuation regulation on the output port which is not based on the OCM feedback.

The OCM unit provides per-channel optical power monitoring on the following ports:

• COM port in output direction

• COM port in input direction

• DROP-TX port in output direction

• Eight Express/Add/Drop (EAD) ports and one Add/Drop (AD) port in both input and output directions

The 80-WXC-C card has 14 types of ports:

• MON: The MON port monitors power on the COM T/R port.

• COM RX: The COM RX port receives the optical signal from a preamplifier (such as the OPT-PRE) and sends it to the optical splitter.

• DROP TX: In the bidirectional mode, the DROP TX port sends the optical signal to the demultiplexer.

• EXP TX: The EXP TX port sends the split off optical signal that contains pass-through channels to the other side of the NE.

• COM T/R: The COM port is bidirectional. It functions as a COM TX port in the multiplexer mode and as a COM RX port in the demultiplexer mode.

• AD T/R: The AD port functions as ADD RX port in bidirectional and multiplexer modes and as a DROP port in the demultiplexer mode.

• EAD T/R i (where i = 1 to 8): The EAD ports function as EXP ports in the bidirectional mode, as ADD ports in the multiplexer mode, and as DROP ports in the demultiplexer mode.

The different units of the 80-WXC-C card are:

• 40/60 splitter with VOA on drop path—The preamplifier output signal from the preamplifier is split in a 40%-to-60% ratio; 40% is sent on the drop path (DROP-TX port) and 60% is sent on the pass-through path (EXP-TX port). The VOA equipped on the drop path is used to match the power range of the receiver photodiode without the need for bulk attenuation. If a channel is expected to be dropped in the 80-WXC-C card, the pass-through channel is stopped after the EXP-TX port either by a 40-WSS-C or a 40-WXC-C card.

• 50 Ghz 10 port WXC—The WXC block is optically passive and has bidirectional capability. The WXC block can selectively send any wavelength combination coming from the eight input EAD ports and one AD port to a common (COM) output port, when used as a multiplexer, whereas it can selectively send any wavelength combination coming from its common (COM) input port to any of the eight output EAD ports and one AD port, when used as a demultiplexer. The WXC block can manage (on each port) up to 80 channels according to the channel grid reported in Table 1. Each channel can be selected from any input and routed to any output.

• 50 Ghz Optical Channel Monitor (OCM)—The OCM provides per channel power monitoring on the COM T/R, DROP-TX, AD, and EADi (i=1 to 8) ports. The power value for each wavelength is refreshed after a variable timer depending on the port and card activity.
