| High Light | Analog Telephone Fiber Converter ，1 Channel Telephone Fiber Converter ，PCM Voice Over Fiber Extender | ||
The 1-channel Telephone Fiber Converter is designed to transmit analog telephone (PCM voice) signals over long distances using fiber optic technology. It converts standard telephone signals into optical signals for transmission through fiber cables, ensuring reliable and interference-free communication.
Unlike traditional copper telephone lines, which are limited in distance and susceptible to electromagnetic interference, this fiber-based solution delivers clear and stable voice communication over distances up to 20km.
Equipped with standard RJ11/RJ45 interfaces, the device is compatible with telephones, PBX systems, and communication equipment. Its compact industrial design allows for easy installation in various environments such as telecom networks, security systems, and industrial sites.
With plug-and-play functionality, no configuration is required, making deployment fast and efficient. LED indicators provide real-time status monitoring of power and fiber link.
This solution is ideal for applications requiring secure, long-distance voice transmission with high reliability and low maintenance.
