About this item

  • The Telephone over fiber system is used to extend telephone signals to remote devices, Using a single SC/SC Fiber Optic cable. Transmission distance can be up to 20Km by single mode fiber, compatible with Multimode fiber up to 300meters, SC fiber interface.
  • Adopt traditional PSTN normal voice, each voice occupies a 64K channel, support caller ID and fax.
  • Transmission bandwidth: 10-100Mbps (per network port) full duplex, half duplex fully adaptive
  • High quality PCM voice telephone Modular design, stable and reliable performance
  • Plug and play, easy to use
