• Position and function in fiber optic networks:

  • Optical network terminal is a key node in the optical fiber network. It is the bridge between the optical fiber network and end-user equipment and is an important part of realizing optical fiber network communication.
  • It has an important function and status in the optical fiber network, which directly affects the transmission quality of optical signals and the stability and performance of the network.

II. Working principle of optical network terminal

• Working mechanism and internal structure:

  • Optical network terminals usually consist of optical receivers, optical transmitters, optical modulators, optical demodulators, electronic chips, interfaces, etc.
  • When the optical signal enters the optical network terminal, the optical receiver is responsible for converting the optical signal into an electrical signal, which is then processed and decoded by the electronic chip, and finally the data is transmitted to the terminal device.
  • When it is necessary to send an optical signal, the optical transmitter converts the electrical signal into an optical signal, modulates it into a specific format of optical signal through an optical modulator, and then transmits it to the optical fiber network through the optical fiber.

• Interaction and data transmission with fiber optic networks:

  • The optical network terminal is connected to the optical fiber network through an optical fiber interface and can receive and send optical signals.
  • When an optical signal enters an optical network terminal, it is received and converted into an electrical signal, which is then processed and decoded by an electronic chip and finally transmitted to the terminal device.
  • When a terminal device needs to send data to an optical fiber network, the data is first converted into an electrical signal, then converted into an optical signal through an optical transmitter, and transmitted to the optical fiber network through the optical fiber.

• Workflow diagram:

  1. Receiving stage: The optical network terminal receives the optical signal from the optical fiber network, converts it into an electrical signal, and transmits it to the terminal device after internal processing.
  2. Sending stage: The terminal equipment generates data, which is converted into optical signals through the optical network terminal and transmitted to the optical fiber network through the optical fiber.
