The WaveReady Transponder 740 LR CWDM (WRT-740 CWDM) is a multi-rate, multi-protocol, auto-lock module that translates optical signals between a variety of client-side interfaces into a long-reach, single-mode course wavelength division multiplexing (CWDM) interface. This module features small form factor pluggable (SFP) modules on the client side as well as loopback and 3R (reshape, re-time, and re-amplify/regenerate) functionalities. The WRT-740 CWDM contains an embedded management channel, which allows for remote management, lowering operating, administration, and management costs. The transponder's WaveReady communication module manages the WRT-740 CWDM using TL1, SNMP, command line interface, or JDSU Node Manager software
