Mitsubishi Electric to Sell 1.3-Micrometer Band 40Gbps EML Module

Tokyo, August 30, 2011 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today the coming launch of a compact 1.3-micrometer band 40Gbps Electro-Absorption Modulator Laser (EML) module for optical signal transmission of up to 10 kilometers by devices used for sending large-volume data. The FU-497SEA, which will launch commercially on November 1, will be presented during the 13th China International Optoelectronic Exposition (CIOE) at Shenzhen Convention and Exhibition Center in Shenzhen, China on September 6-9.

As online traffic continues to increase at rapid pace, 10Gbps optical interfaces for networks are giving way to faster 40Gbps interfaces. Mitsubishi Electric's existing 40Gbps EML module, the FU-697SEA, uses the 1.55-micrometer band for transmissions that are limited to about two kilometers due to wavelength dispersion. As chromatic dispersion at 1.3 micrometers is almost negligible, Mitsubishi Electric's new 1.3-micrometer band EML chip delivers high signal quality for 40Gbps optical transmissions over distances of up to 10 kilometers.


Main Features

High signal quality for transmissions of up to 10km
-Transmission penalty is less than 1dB after 10km using single-mode fiber
-High extinction ratio (10dB, typical) and high mask margin (10%, typical) at 43Gbps operation
Use of general-purpose interface for 40Gbps electrical connection
-Dual SMPM connectors for differential connection between modules and digital signal circuits help to simplify system designs for transmission equipment
