    Wekuant 2 x RJ11 Telephone and 10/100 Mbps Ethernet Over Fiber Converter - POTS to Fiber Optic Extender, Universal Single Mode up to 20Km(12.4 mi) and Multimode 500m(0.31 mi), A Pair.

    • Extend PCM Voice Telephones and Network signal: 2 Independent telephone lines + 1 Ethernet (10/100 Mbit/s) port through same fiber optic cable to far end. Suitable for Both Fiber Types (Single-mode and multimode). Single-mode fiber for a long distance up to 20 km(12.4 miles), Multimode fiber for a distance up to 500m(0.31 miles).
    • Support Called id, Ring and Fax function, No Delay Transmission and Protocol Support: Unlike VoIP products - these converters transmit signals directly over fiber cables, thus offering NO DELAYS, plus support for fax & legacy applications that is not supported by VoIP lines.
    • With our Telephone over Fiber extender you can get faster speeds, less signal degradation, longer distance data transfer, better reliability, and more flexibility. Using a fiber optic cable can decrease costs over time because of the durability and reliability of the fiber cables. Fiber optic cables carry a low rate of bit error due to the fiber being highly resistant to el
