Long Reach, Client-Side SFP, Multi-Rate, Multi-Protocol,
CWDM, 3R Transponder
WaveReady™ Transponder 740 LR CWDM
Key Features
• Client-side SFP modules support either single-mode (SMF)
or multi-mode fiber (MMF)
• Automatic bit rate detection and reporting
• Multiple protocols supported at discrete bit rates of 125 Mb/s
to 2.7 Gb/s
• Network optics support eight CWDM channels using 20-nm
channel spacing
• Facility loopback functionality on both network and client sides
• Remote management with SNMP traps or TL1
• 3R functionality at all supported bit rates and protocols
Applications
• Wavelength services
• Metro optical access overlay
• Storage area network (SAN) and
GigE extension services
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
