WaveReady™ WRT-780
Dual Multirate WDM Transponder (125 Mb/s–4.25 Gb/s)
Flexible WDM Transport Solution
The JDSU WaveReady WRT-780 is a dual multirate transponder that can support
an extended number of services for both coarse (CWDM) and dense wavelength
division multiplexing (DWDM) transport applications. Due to its high flexibility
and density, the WRT-780 is the ideal transport solution for access and metro
wavelength division multiplexing (WDM) networks.
The module has two independent transponders that can transport traffic running
at different rates. The WRT-780 can also be used as a bidirectional four-port
regenerator. Its flexible pluggable (SFP) interfaces support a variety of trans-
ceivers on both client and line interfaces (850, 1310, and 1550 nm; DWDM; and
CWDM).
Automatic Rate Detection
The WRT-780 automatically detects incoming data rates so end-user provisioning
is not required. The WRT-780 supports 3R operation (reshape, retime, and
regenerate) at all supported rates between 125 Mb/s and 4.25 Gb/s.
Simple and Easy to Manage
The WRT-780 can be managed using TL-1, simple network management protocol
(SNMP), or by using the WaveReady Node Manager graphical user interface. The
dual-transponder also supports manual data-rate provisioning, diagnostic
loopback for testing, optical power monitoring, and other features. These
functions facilitate fault location and correction and simplify operations required
by service management and service level agreements.

WRT-780 Dual Multirate WDM Transponder
Because of its high density and flexibility, the WRT-780 enables reliable, scalable
and cost-effective transport solutions for both CWDM and/or DWDM networks.
The easy-to-use WRT-780 transponder combined with the plug-and-play features
of the WaveReady platform makes the turn-up of new services easy and simplifies
equipment management.
Where extended reach is required, the WRT-780 can be combined with
WaveReady DWDM amplifiers and dispersion compensation modules to provide
a dense and compact DWDM transport solution.
With the growing need to have storage area networks (SANs) extended over long
distances to support enterprise connectivity or disaster and recovery solutions, the
WRT-780 can be combined with the WaveReady WDM platform to offer a simple,
reliable, and cost-effective SAN transport solution.
