• Bare fiber optical waveguide, also known as “bare device”, is the core device in optical passive network.
  • Its function is to divide optical signals into multiple channels or synthesize them.
  • Its structure is composed of optical shunting chip and optical fiber array.
  • Bare fiber optical waveguide is an integrated optical waveguide power distribution device based on quartz substrate.
  • It has the advantages of small volume, wide working wavelength range, high reliability and compact structure.
  • It is widely used in the construction of passive optical network and FTTX system.
