Chapter 1 Product Overview
Cisco ONS 15540 ESPx Components
lists the LEDs for the 10-Gbps line card motherboard.
Transponder Modules
In the transponder module, the client signal is converted to an ITU-compliant
wavelength, which is cross-connected over the optical backplane to the
mux/demux modules. You can populate the line card motherboard subcard slots
with as few or as many transponder modules as required (up to 32) to support the
desired number of client signals or data channels.
The Cisco ONS 15540 ESPx supports four types of interface transponder
modules:
•
SM (single-mode) transponder modules
•
MM (multimode) transponder modules
•
Type 2 extended range transponder modules with SFP optics
•
10-GE transponder modules
