Optical Network Terminal

What is an optical network terminal?

Optical Network Terminal (ONT) is a terminal equipment in the optical fiber access network and is a key equipment used to implement fiber-to-the-home (FTTH). ONT can convert optical signals into electrical signals and provide Ethernet, Wi-Fi and other interfaces for users to access the Internet, IPTV and other services for home or enterprise users.

Functions of optical network terminals:

  • Photoelectric conversion: Convert optical signals into electrical signals.
  • Ethernet/Wi-Fi access: Provides Ethernet and Wi-Fi interfaces for users to access the Internet, IPTV and other services.
  • Network functions: Support VLAN, QoS and other functions to meet the needs of different users.
  • Security management: Supports security functions such as firewall and MAC address filtering.

Applications of optical network terminals:

  • Fiber to the home: used for fiber access for users such as homes and businesses.
  • Metropolitan area network: used to build the access layer of the metropolitan area network.
  • 5G network: used for access to 5G base stations.

Advantages of optical network terminals:

  • High transmission rate: supports high transmission rates such as Gigabit and 10 Gigabit.
  • Long transmission distance: The optical fiber transmission distance is not affected by electromagnetic interference and can reach tens of kilometers.
  • Strong anti-interference ability: Optical fiber transmission signals are not easily eavesdropped or intercepted.
  • High security: Optical fiber transmission signals are not easily interfered with.
