Furukawa Electric Co., Ltd. has developed an 8-channel TOSA (Transmitter Optical Sub-Assembly) for CPO ELS employing a blind mate optical connector. Data traffic has been increasing to support many kinds of IT services such as cloud services and 5G mobile networks. Hyperscale data centers that process big data and edge data centers that realize the low latency for Beyond 5G are faced with the challenge of expanding bandwidth and reducing the power consumption of a network switch server. CPO -...

Mitsubishi Electric Corporation announced that it has developed a 200Gbps (112Gbaud four-level pulse-amplitude modulation (PAM4)) electro-absorption modulator laser diode (EML) chip that doubles the speed of the company's existing 100Gbps EML chip thanks to a proprietary hybrid waveguide structure. Support for coarse wavelength division multiplexing (CWDM) of four wavelengths realizes 800Gbps transmission using four chips or 1.6Tbps using eight chips. improved performan...
