Sony Introduces 25Gbps/ch Short reach for optical communication module
Sony has established mass-production technology of an optical communication module for data center networks. Sony has developed this high-speed interface for transmitting large-data, high-resolution images. The company will exhibit this technology and product (QSFP28, 100G) at OFC2016 to be held in Anaheim, California from March 22, 2016. The technology is planned to be available in the first half of 2016.

For the cloud computing market, which is moving toward high-speed, large-data in the future, Sony will apply its technical innovation of optical communication module using the semiconductor packaging process that have been refined as the transmission technology of large-data, high-resolution images ( Figure 1). Sony will continue to expand its line-up of optical communication module for data center network application.
Main underlying technology
Sony has deployed semiconductor laser technology, developed through many years of production experience with red, and blue laser technology, to the communication laser. Sony has successfully developed broadband and high reliability of the VCSEL/PD to realize the transmission of 25Gbps, and has achieved mass production introduced for the optical communication module.
- High reliability of the cumulative failure rate of 0.1% : 60yrs
