Optical transceiver: Optical receiving chip
We have developed the world’s smallest optical receiver chip for TWDM-PON.
Optical receiver chip for optical transceivers used in optical communication networks (demonstrates reception operation)
Optical receiving chip:
Employs a system (four-wavelength multiplexing) that receives four optical signals with different wavelengths.
A total of 40 Gbps optical signals can be received regardless of the polarization state.
Ultra-miniaturization is realized by adoption of silicon photonics technology.
It has become possible to develop ultra-small optical transceivers that can be built into small cell base stations used in 5th generation mobile communication (5G) networks.
It is expected that 5G services such as high-definition video content delivery in mobile environments will be available in a wider area.
July 7 PETRA and OKI make a presentation at the International Conference on Optoelectronics and Communications Conference (OECC) 2019.
