MRV Muxponder Modules Enable Backbone Aggregation for Gigabit Ethernet Links

MRV Communications Inc. (Booth 918) has introduced the TM-GM8D and TM-GM8CD, two eight-port gigabit Ethernet muxponder modules for its LambdaDriver WDM platform. They provide cost-effective aggregation of gigabit Ethernet links onto a 10-gigabit DWDM backbone.

The TM-GM8D optical module uses eight SFPs for network access, while the TM-GM8CD copper module uses RJ45 connectors for network access. The aggregation port on both modules is 10-gigabit DWDM with wavelength tunability and several options for increased distances.

Both hot-swappable modules maximize the efficiency of a WDM platform by providing cost-effective fiber or copper connectivity. In comparison with switched aggregation solutions, the LambdaDriver muxponder modules can offer a separate channel for a customers data, providing an added layer of data security for sensitive government, financial and other applications.

While gigabit Ethernet access networks are gaining in popularity with carriers, there is no one typical deployment scenario. Thus, we are expanding the capabilities of the LambdaDriver with these new modules to provide carriers with a very cost-efficient Ethernet backbone for either copper or fiber, said Noam Lotan, CEO of MRV Communications Inc. Both modules offer the same ability to use advanced TDM to aggregate eight gigabit Ethernet ports, thereby maximizing utilization of the cable plant and minimizing cost of implementation.

The modules fully support link integrity notification to disable access ports when the trunk port is not receiving information. When combined with the LambdaDriver element management module, full power monitoring and configuration capabilities become available locally at a craft terminal via the RS-232 interface and remotely at a TELNET or SNMP station via an Ethernet or Fast Ethernet interface.

Each module comes in fixed versions with DWDM links for distances of up to 40km and 80km and in a tunable version capable of up to 80km. Longer distances can be reached using optical amplifiers and dispersion compensation modules.

The LambdaDriver TM-GM8D and TM-GM8CD are available from MRV and its worldwide network of resellers.
