MRV Communications, a provider of scalable network infrastructure
equipment, Monday announced the availability of a 10 Gigabit transponder module
for its Lambda Driver CWDM/DWDM transport platform.
The TM-DXFP
10 Gigabit transponder supports both STM64/OC-192 (9.955 Gbps) and 10 Gigabit
Ethernet protocols for use in metro and long-haul service provider networks.
The new transponder is capable of spanning distances of up to 80 Km over G652 fiber-optic cable without a need for amplification or dispersion compensation. Longer distance transmissions can be achieved using dispersion compensation and Optical Amplifier modules.
The 10 GigE module is already deployed with service providers and has been used to upgrade existing WDM
backbones from 2.5 Gbps to 10 Gbps Ethernet.
The TM-DXFP transponders are single slot modules that interface between
the CWDM or DWDM multiplexers and 10 Gbps terminal equipment. The modules can
be used throughout the Lambda Driver family, including the five-slot LD400,
11-slot LD800 and 16-slot LD1600 chassis.
"Our recent industry surveys indicate there is strong momentum for the
proliferation of Ethernet services worldwide due to the promise of more
bandwidth for the buck and greater service agility, but that end users will
expect the quality of service and performance they have with existing
services. As the market unfolds, we expect to see increased demand for
10 Gigabit transport solutions from players like MRV," said Stan Hubbard,
senior analyst for the research firm Heavy Reading.
"The emergence of 10 Gbps Ethernet technology facilitates the
implementation of bandwidth-intensive applications," says Noam Lotan, MRV's
president and CEO.
"This is important as carriers refocus their investment on
the access portion of the network. We are further strengthening our position
in the CWDM/DWDM market by introducing these optical transport solutions for
10 Gbps Ethernet and OC-192. The new transponders enable our customers to
smoothly upgrade their existing infrastructure to 10 Gbps/OC-192 speed."
The transponder module uses XFP — 10 Gigabit SFP (Small Form Factor
Pluggable) transceiver receptacles to provide increased flexibility in
choosing the optical interface of the terminal equipment. XFP transceivers
are pluggable, and can be easily reused at different locations for different
applications, thus maximizing the return on investment in optics and
equipment, and reducing the need for on-hand parts inventory.
By using the
XFP receptacle, the same transponder can support any possible optical
interface.
Two versions of the transponder module are available now, including a
metro-distance (40 Km) version for both Gigabit Ethernet and SONET/SDH, and a
long-haul (80 Km) version supporting the same protocols.
