Optical Communication Devices

Supporting the progression of an Advanced Information Society in the Optical Communications Field

Amongst the various types of optical communication devices, KYOTO SEMICONDUCTOR Co., Ltd. is concentrating its efforts in the field of fiber-optic power monitors for Optical communication Networking Systems.

KYOTO SEMICONDUCTOR is proud to hold the dominant worldwide market share. Fiber-optic power monitors are primarily used in long-haul (backbone) systems and metropolitan networks. The market continues to grow and expand into Data communications and CATV markets. We are striving to capture market share in the field of Duplexer or Triplexer modules for FTTH and FTTP. We expect to see a rapid increase in demand for both domestic and overseas markets such as Korea, Taiwan, China and USA in the fields of not only the receiver but also the transceiver for FTTH and FTTP solutions in future.

Long-wavelength Photodiodes

  • Long-wavelength Photodiodes
  • Long-wavelength Photodiodes

The long-wavelength photodiodes and its related module products developed and manufactured by KYOTO SEMICONDUCTOR Co., Ltd. support long-haul and metropolitan networking systems based on DWDM (Dense Wavelenght Division Multiplex) and FTTX Subscribers (Fiber to the Home/ Fiber to the Building/ Fiber to the Premises /etc.). Our optoelectronic components are incorporated into DWDM systems, Optical Amplifiers, ONUs (Optical Networking Unit), ONTs (Optical Network Terminal), Routers, Receivers and Transmitters,etc.
And, these are photo-conversion devices used in Internet and LAN (Local Area Network) that are electronic components essential to build an optical network infrastructure to support the worldwide community.

Semiconductor Lasers

  • Semiconductor Lasers

KYOTO SEMICONDUCTOR VCSEL (Vertical Cavity Surface Emitting Laser diode, VCSEL) with the peak wavelength of 850nm is designed for application of short range and high-data-rate transmission systems. Our VCSEL product lineup comprises 3 types in 3 kinds of packages, respectively.
Two kinds of VCSEL devices are hermetically sealed;one is packaged in metal can with a lens, and another is packaged in isolated mini can.
Last is LC-receptacle type of TOSA (Transmitter Optical Sub-Assembly).
Each signal modulation is available up to 4GHz.
