New Fibre Channel 4, 2 and 1Gbps transponders boost distance for business continuity storage solutions

MRV Communications Inc, a provider of products and services for out-of-band networking, WDM and optical transport, metro Ethernet, fiber optic components, 10G and other service aware networking products, have announced the addition of new transparent transponders for the LambdaDriver family of wave-division multiplexing (WDM) systems, which provide 4-Gigabit Fibre Channel data transport for storage area networks.

The TM-D4GSFP is a DWDM transponder that supports distances up to 100km over G652 compatible fiber-optic cable without power or dispersion compensation. The TM2-SFP4G is a dual circuit, SFP-based transponder, similar to MRV's 2.7-Gbps TM2-SFP transponder. The use of SFPs for both access and WDM results in a high level of flexibility and lower maintenance costs. The maximum distance possible with existing WDM SFP solutions over G652 fiber is 70km. The hot-swappable MRV SFPs are available as either CWDM or DWDM modules.

With the TM-D4GSFP and TM2-SFP4G, system architects have the ability to use the LambdaDriver platform to support Gigabit, 2-Gigabit and 4.25-Gigabit Fibre Channel in a single chassis for simplified backbone network scaling, resulting in CAPEX and OPEX savings. Other Fibre Channel protocols can also be transported using these new modules. Manageable by MRV's Megavision Pro Management System, these transponders support functions like rate selection and loopback set-ups as well as power monitoring of the optical ports. These transponders can be used with amplifiers and DCMs for networks needing transmission distances longer than 100km.

Featuring full 3R support, these transponders offer both remote and local loop-back functionality. Full power monitoring, SFP digital diagnostics and link integrity notification (LIN) all come standard. The new modules can be used throughout the LambdaDriver family, including the five-slot LD400, 11-slot LD800 and 16-slot LD1600 chassis, and with the LambdaDriver management module using MRV's Megavision Pro Management System, the transponders can be monitored and controlled via SNMP.
