Chapter 2 Cards Specifications
2.1 Card Overview
• Multiplexer and demultiplexer cards multiplex and demultiplex DWDM optical channels. The cards
consist of three main modules: an optical plug-in, a microprocessor, and a DC/DC converter.
ONS 15454 multiplexer and demultiplexer cards include the 32-Channel Multiplexer (32MUX-O),
the 32-Channel Demultiplexer (32DMX-O), the single-slot 32-Channel Demultiplexer (32DMX),
and the 4-Channel Multiplexer/Demultiplexer (4MD-xx.x).
• Optical Add/Drop Multiplexer (OADM) cards are mainly divided into three groups: band OADM
cards, channel OADM cards, and wavelength selective switch (WSS) cards. Band OADM cards add
and drop one or four bands of adjacent channels; they include the 4-Band OADM (AD-4B-xx.x) and
the 1-Band OADM (AD-1B-xx.x). Channel OADM cards add and drop one, two, or four adjacent
channels; they include the 4-Channel OADM (AD-4C-xx.x), the 2-Channel OADM (AD-2C-xx.x)
and the 1-Channel OADM (AD-1C-xx.x). The 32-Channel Wavelength Selective Switch (32WSS)
card is used with the 32DMX to implement reconfigurable OADM (ROADM) functionality. These
cards consist of three main modules: an optical plug-in, a microprocessor, and a DC/DC converter.
Table 2-1 to Table 2-4 show the band IDs and the add/drop channel IDs for the 4MD-xx.x,
AD-2C-xx.x, AD-4C-xx.x, and AD-4B-xx.x cards.
