The WaveReady Transponder 760 (WRT-760) is a multi-rate, multi-protocol, auto-lock transponder module that translates optical signals between a variety of client-side interfaces into a long-reach, single-mode, dense wavelength division multiplexing (DWDM) interface. This module includes path protection, small form factor pluggable (SFP) modules on the client side, loopback, and 3R (reshape, retime and re-amplify/regenerate) functionality.
Built-in path protection eliminates the need for extra transponders and protection devices on protected links, a significant saving in capital expenditure.
SFP modules optimized for a wide range of protocols are available for singlemode and multimode fiber. Supported protocols include 100Base-FX Ethernet, Gigabit Ethernet (GigE), ESCON, Fibre channel, FICON, and OC-3 to OC-48. Supported data rates range from 125 Mb/s to 3.125 Gb/s. The WRT-760's bit-rate and protocol independence gives service providers the flexibility to meet the shifting service demands of customers without changing installed equipment.
Full 3R functionality allows multiple WRT-760 modules to be deployed in series for very long reach applications. Loopback facilitates fault isolation and troubleshooting.
