Chapter 1 Cisco ONS 15530 Overview
Cisco ONS 15530 Components
The transponder line cards are hot swappable, permitting in-service upgrades and replacement. All client
signals on the transponders are supported in 3R (reshape, retime, retransmit) mode, regardless of
protocol encapsulation type. The client interfaces also support the OFC (open fiber control) safety
protocol for Fibre Channel, ISC compatibility mode, and FICON. The client side ports use SC-type
connectors.
On the trunk side, the transponder line card output laser power ranges from 5 to 10 dBm and the receive
detector has a sensitivity of –32 dBm. The ports on the trunk side use MU-type connectors.
Transponder Line Card LEDs
Table 1-7 lists the LEDs on the transponder line card faceplate, their default conditions, and what the
conditions indicate.
OADM Modules
The OADM modules 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).
In the transmit direction, the OADM modules multiplex signals transmitted by the transponder line cards
and 10-Gbps ITU trunk cards over optical cross connections and provide the interfaces to connect the
multiplexed signal to the DWDM trunk 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 10-Gbps ITU trunk cards.
