Multifuctional 2/4/8 POTS RJ11 Telephones + additional 4 Independent Gigabit Ethernet over Fiber Optic Converters
Feature:
1. The phone over fiber extenders can offer a low-cost solution for extending limited reach POTS telephone lines to fiber optical distances of over 12.4 miles using Single Mode (SM) type optical fibers and 0.31 miles using Multimode (MM) fibers. Besides extending 2/4/8 POTS telephone lines over the same fiber, it also can carry 4 Independent (Isolated) Gigabit (10/100/1000Mbps) Autosensing Ethernet RJ-45 network port, which offers even more effective re-use of fiber cables.
2. Suitable for universal Fiber Types: Same extender supports Single mode fiber and Multimode fiber, Long transmission distance, SM(Single mode) up to 20 km (12.4 miles), MM(Multimode) up to 500m(0.31miles).
3. Our Phone over Fiber extenders can solve the problem of lighting protection for your home/office etc. Because Lengthy copper cables, installed outdoors, are prone to attracting lightning, and this can damage electrical equipment in your homes.
4. 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.
5. Plug and Play, Easy to operate. No setup or configuration needed, SC connector for fiber port, RJ-11 connector for telephone ports , RJ-45 for Gigabit Ethernet Autosensing port.
Remark ：2/4/8 port telephone share same metal box.
One set (TX and RX), Fast Shipping.
