Product Description

The 2-channel Telephone Fiber Converter is a professional communication device designed to extend two independent telephone (PCM voice) channels over long distances via fiber optic cable. It converts analog voice signals into optical signals, enabling reliable and interference-free transmission.


Featuring dual RJ11/RJ45 ports (P1 & P2), the device supports simultaneous connection of two telephones or PBX extensions. It is ideal for enterprise communication systems, campus networks, industrial communication, and remote site voice connectivity.


Compared to traditional copper-based telephone lines, this fiber optic solution eliminates signal attenuation, noise, and electromagnetic interference, ensuring crystal-clear voice quality even over distances up to 20km.


With a plug-and-play design, no configuration is required. The compact metal housing allows for easy installation in various environments, while LED indicators provide real-time monitoring of power and fiber link status.


This device is particularly suitable for applications where multiple voice channels need to be transmitted securely and reliably over long distances.
