Applications
• Wavelength services
• Metro optical access overlay
• Protected storage area network
(SAN) and GigE extension services
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 single-
mode 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.

1. Due to the dual media (single-mode and multimode) support of this transmitter, fulfillment of this protocol requires a single-mode fiber offset launch mode conditioning
patch cord. The offset launch mode conditioning cable lowers the launch power by 0.5 dB and incurs a similar penalty on the sensitivity.
