Optical Transmission System

What is an optical transmission system?

Optical transmission system refers to a system that uses optical fiber as a transmission medium to transmit information in the form of optical signals. Optical transmission systems have the advantages of high transmission rate, large capacity, and strong anti-interference ability, and have become an important part of modern communication networks.

Core technology:

  • Optical fiber: Thin and strong optical fiber carries high-speed transmission of optical signals and is the foundation of the optical transmission system.
  • Optical devices: Optical transmitters, optical receivers, optical amplifiers and other optical devices convert, amplify and modulate electrical signals and optical signals to realize the transmission and processing of optical signals.
  • Transmission system: The optical transmission system consists of optical fibers, optical devices and supporting equipment to realize end-to-end transmission of optical signals.

Key advantages:

  • High speed: The optical transmission system can provide ultra-large bandwidth, support high-speed data transmission, and meet the needs of emerging services such as the Internet, 5G, and cloud computing.
  • Low loss: Optical fiber transmission loss is low, signal attenuation is small, and long-distance transmission can be achieved.
  • Anti-interference: Optical signals are not affected by electromagnetic interference, and the transmission is stable and reliable.
  • Security: The optical transmission system has high security and is not easy to be eavesdropped and intercepted.

Application scenarios:

  • Telecommunications network: Optical transmission systems build backbone networks, metropolitan area networks, access networks, etc., carrying voice, data, video and other services.
  • Internet: Optical transmission systems build the Internet backbone and backbone networks to achieve high-speed data interconnection.
  • Data center: The optical transmission system builds the internal network of the data center to realize high-speed interconnection between servers.
  • Radio and television network: Optical transmission system is used for TV signal transmission to realize high-definition TV program broadcast.
