Mitsubishi Electric develops new optical transmission devices for next-generation 100 Gb Ethernet applications

摘要

Mitsubishi Electric Corp. has developed transmission devices featuring characteristics for super high-speed, 100 Gb Ethernet applications that multiplex four wavelength channels of 25 Gbps-speed optical signals in parallel.rnOf the two devices, the high-speed, direct modulation-distributed feedback (DFB) laser diode, which is incorporated in devices that send out optical signals, features modulatedrnwaveforms of 25 Gbps. The photo diode array, which is incorporated in receiver modules, has a responsivity of 0.88 amperes per watt (A/W).
