Product Name: 15454-WSS-L

This document provides a card description, specifications, and installation procedure for the dense 
wavelength division multiplexer (DWDM) 32WSS-L card. The 32WSS-L card is compatible with Cisco 
ONS 15454 SONET (ANSI) and Cisco ONS 15454 SDH (ETSI) shelf assemblies. Use this document in 
conjunction with the Cisco ONS 15454 DWDM Procedure Guide when working with 32WSS-L cards.

This document contains the following sections:

The 32-Channel Wavelength Selective Switch L-Band (32WSS-L) card performs channel add/drop 
processing within the ONS 15454 DWDM node. The 32WSS-L works in conjunction with the 
32DMX-L to implement ROADM functionality within the L band (1570 to 1620 nm). The 32WSS-L 
card is well suited for use in networks that employ DS fiber or SMF-28 single-mode fiber. Equipped with 
ROADM functionality, a DWDM node can be configured to add or drop individual optical channels 
using Cisco Transport Controller (CTC), Cisco MetroPlanner, and Cisco Transport Manager (CTM).

An ROADM node utilizes two 32WSS-L cards (two slots each) and two 32DMX-L cards (one slot each), 
for a total of six slots in the chassis. For a diagram of a typical ROADM configuration, see the 
Cisco ONS 15454 DWDM Reference Manual. The two-slot 32WSS-L card can be installed in Slots 1 and 
2, 3 and 4, 5 and 6, 12 and 13, 14 and 15, or 16 and 17.
