Cisco 2-Channel SFP WDM Transponder
The Cisco
®
2-Channel SFP WDM Transponder expands the range of applications and
platforms supported by coarse wavelength-division multiplexing (CWDM) and dense
wavelength-division multiplexing (DWDM) pluggable optics solutions from Cisco. It
supports any client, any protocol, and any speed between 155 Mbps (OC-3/STM-1) and
2.488 Gbps (OC-48/STM-16).
Product Overview
The Cisco 2-Channel SFP WDM Transponder (Figure 1) is an unmanaged unit that can be used to
convert any incoming optical signal into a CWDM or DWDM channel. Its flexibility in terms of data
rates, protocols, and wavelength-division multiplexing (WDM) options is provided by Cisco
pluggable optics, which reside on both the client side and the trunk side.
In addition, when Small Form-Factor Pluggable (SFP) devices with the same wavelength reside on
client and trunk sides, the unit can be simply used as a 3R regenerator (re-amplification, reshaping
and retiming) for the uplink data stream (client to network path) and a 2R regenerator (re-
amplification and reshaping) for the downlink data stream (network to client path), turning it into a
very dynamic and flexible module.

The transponder effectively extends the range of client devices that can connect to the CWDM or
DWDM network using pluggable optics: third-party SONET/SDH add/drop multiplexers (ADMs),
storage and Ethernet devices, or Cisco platforms that do not support pluggable WDM optics can
connect to the WDM network by using this transponder, which operates the wavelength conversion
from older 850/1300/1550 nanometer (nm) signals to any CWDM or DWDM channels. This
conversion is enabled by the WDM SFP ports sitting on the line side (Figure 2).
