16/24/48/64 Channel Telephone 4 Port Gigabit Ethernet Fiber Optic Extender
The 16/24/48/64 Channel Telephone + 4-Port Gigabit Ethernet Fiber Optic Extender is a high-capacity communication transmission solution that integrates multiple analog telephone lines and Gigabit Ethernet services into a single fiber optic link.
Built with advanced PCM voice encoding technology and industrial-grade optical transmission architecture, the system supports simultaneous transport of up to 64 FXS telephone channels and 4 Gigabit Ethernet interfaces over long distances without signal degradation.
Designed for telecom operators, enterprise communication systems, government projects, transportation infrastructure, universities, hospitals, hotels, industrial parks, and large campuses, the equipment provides a reliable and cost-effective alternative to traditional copper cabling.
The device supports transparent voice transmission, high-speed Ethernet connectivity, low latency communication, and excellent electromagnetic interference resistance. With plug-and-play operation and centralized fiber deployment, installation and maintenance costs are significantly reduced.
