Transmitter
In the transmit direction, the transceiver module receives a 10-Gbps electrical data signal and
transmits the data as an optical signal via an E/O converter. The optical output power is held
constant by an automatic power control circuit. The transmitter also contains a Clock Data
Recovery (CDR) circuit. The function of this circuit is to attenuate and reshape any jitter received
on the electrical interface.
Receiver
In the receive direction, the transceiver module receives a 10-Gbps optical signal and converts it to
an electrical equivalent. The receiver contains a CDR circuit.

Pluggable Modules: List and Description
Cisco ONS Family modules have well-defined product IDs, making it easy for you to order the
appropriate module.
The product ID is structured as follows: ONS-”AB”-”CCC”-”DD”.
●
A = S for SFP, G for GBIC, and X for XFP
●
B = C for commercial temperature (0 to 70°C), E for extended temperature (–10 to 85°C),
and I for industrial temperature (–40 to 85°C)
●
CCC = Supported bit-rate or signal type: 155 Mbps for OC-12/STM-1 signal or 2 GF for a
tri-rate Gigabit Ethernet, Fibre Channel, and 2G Fibre Channel signal support
●
DD = Supported reach: S1 for short-reach/intra-office 1310 nm interface or SX for Ethernet
