Applications
• Wavelength services
• Metro optical access overlay
• Storage area network (SAN) and
GigE extension services
The WaveReady Transponder 740 (WRT-740) 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, dense wavelength division multiplexing
(DWDM) interface. This module includes small form factor pluggable (SFP)
modules on the client side, loopback, and 3R (reshape, retime and re-
amplify/regenerate) functionality.
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-740's bit-rate
and protocol independence gives service providers the flexibility to meet the
shifting service demands of customers without changing installed equipment.
Remote management lowers operating, administration and management
expenditures (OPEX). A WaveReady communications module manages the WRT-
740 with TL1 and a command line or telnet interface, or with TL1 or simple
network management protocol (SNMP) and the JDSU Node Manager software.
An embedded supervisory channel on the network side is also available for remote
management of standalone modules without the cost of extra fiber or an extra
WaveReady communications module.
Full 3R functionality allows multiple WRT-740 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.
