Optical Fiber Communication Devices

Contributing to the realization of digital transformation (DX) by enabling high-speed/high-capacity optical fiber communication when equipped in large-scale data centers, optical fiber communications for homes (FTTH), mobile communication base transceiver stations (BTS) such as 5G, and various other communications equipment.


High-speed transmission, large capacity, miniaturization, and low power consumption of optical transceivers

Main Applications

Data centers, Fiber-to-the-Home (FTTH), 5G base transceiver stations (BTS), and more
