Optical Add Drop Multiplexing Modules
The OADMmodules are passive devices that optically multiplex and demultiplex
a specific band of four ITU wavelengths. The OADM modules supported by the
Cisco ONS 15530 each add and drop a specified band of four channels at a node
and pass the other bands through. To support the 32-channel spectrum, there are
eight different 4-channel cards (see Figure 1-16).
Inthe transmit direction, the OADM modules multiplex signals transmitted by the
transponder line cards and 10G ITU trunk cards over optical cross connections
and provide the interfaces to connect the multiplexed signal to the DWDMtrunk
side. In the receive direction, the OADM modules demultiplex the signals from
the trunk side before passing them over optical cross connections to the
transponder line cards and 10G ITU trunk cards.
RX (Trunk port) Green Light reception exists at the port.
WEST1Green Card is listening to the west side signal.
TX (Client port) Green Port is up and transmit laser is enabled.
RX (Client port) Green Light reception exists at the port.
