FOR IMMEDIATE RELEASE No. 3183

TOKYO, March 7, 2018 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will begin shipping a laser-diode transmitter optical subassembly (TOSA) capable of supporting 400Gbps optical transmissions on April 1. The new TOSA, when used in a set of two, can be used in the industry's first electro-absorption modulated laser diode (EML)-TOSA solution for IEEE 400GBASE-LR8 applications. The device will be displayed at the Optical Fiber Communication Conference and Exhibition 2018 (OFC) in San Diego, California from March 13 to 15.

In response to the demand for increasing data capacity, Mitsubishi Electric's new laser-diode TOSA offers 400Gbps transmission capability for large-capacity communication facilities (data centers, etc.) and high-speed optical transmission networks.

Product Features

  1. Large-capacity, high-speed 400Gbps communication
    • Multiple transmission of eight wavelengths by two TOSAs
    • 50Gbps/wavelength (400Gbps in eight wavelengths) achieved with 4-level pulse-amplitude modulation (PAM4) method
    • Capable of 10km transmission thanks to EML chip featuring high extinction ratio and high power
    • Package size complies with common specifications for CFP8 optical transceivers (when using two TOSAs)
