OREANDA-NEWS. Mitsubishi Electric Corporation announced today that it has developed a laser diode-transmitter optical subassembly (TOSA) that enables 100Gbps optical transmission in one fiber using four-channel wavelength-division multiplexing, which will help to downsize 100Gbps communication facilities and expand high-speed 100Gbps optical transmission networks. Shipments will begin on April 1, 2014.

The FU-401REA TOSA features four electro-absorption modulators with laser diode (EML) and an optical multiplexer integrated in one compact package. This is one of the world's lowest power and most compact EML-TOSA solutions for IEEE 100GBASE-LR4 applications.

The FU-401REA will be exhibited at the Optical Fiber Communication Conference and Exposition 2014 (OFC) in San Francisco, California from March 11 to 13, 2014.

As 10Gbps optical network interfaces give way to 40Gbps and 100Gbps interfaces, installations in confined spaces are requiring the use of smaller and lower-power equipment. Needs for downsized, low-power EML-TOSAs led to the development of Mitsubishi Electric's FU-401REA TOSA, which will help meet the demands for smaller equipment and thereby expand the market for 100Gbps EML-TOSAs.
