Cisco 2-Channel SFP WDM Transponder expansion module

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.
