Optelian adds ROADM and network monitoring to lineup

OCTOBER 6, 2009 -- Optelian has announced the availability of two new system cards, the RDM-2x1 and OCM-40, for reconfigurable optical add/drop multiplexing (ROADM) and network monitoring applications.

OCTOBER 6, 2009 -- Optelian, a designer and manufacturer of optical transport systems, has announced the availability of two new system cards, the RDM-2x1 and OCM-40, for reconfigurable optical add/drop multiplexing (ROADM) and network monitoring applications.

The ROADM capabilities allow network operators to realize operational savings when reconfiguring optical channels at remote locations. Rather than sending technicians to a site, provisioning is done easily and quickly at the operations center. Traffic can be rerouted instantly in response to service requests or fiber cuts.

The RDM-2x1 features include unrestricted add/drop of 40 channels at 100-GHz spacing, remote per-channel power equalization with >15-dB dynamic range and other optical specifications allow cascading of RDMs for all-optical transmission at distances greater than 1,000 km.

Optical channel monitors (OCMs) that continuously monitor and report the optical power levels of all forty 100-GHz-spaced DWDM channels are useful for remote performance monitoring, fault localization, and optical power balancing. Installing OCMs on new or existing DWDM and ROADM systems eliminates the need to dispatch technicians with optical spectrum analyzers.

Optelian's OCM-40 features two monitor inputs for simultaneous monitoring of both east and west directions, high accuracy over temperature and life with no user calibration needed, and acquisition time less than 200 ms for a complete spectral scan of both ports.

"The RDM-2x1 and the OCM-40 are key building blocks in agile optical networks," says Dave Mills, vice president, sales for Optelian. "With these new cards, network operators get all the benefits of LightGAIN systems including low power consumption, ease of deployment, and decades of worry-free operation."
