Multifuctional 2/4/8 POTS RJ11 Telephones and 2 Independent Gigabit Ethernet over Fiber Optic Converters ,One set (TX and RX)

Description:

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 (optional) telephone lines over the same fiber, these extenders also can carry 2 Gigabit Autosensing Ethernet RJ-45 network port, which offers even more effective re use of fiber cables.

Even more importantly, – besides the extension, which more often than not, happens outdoors, Our Phone over Fiber extenders solves the problem of lighting protection for your home. Lengthy copper cables, installed outdoors, are prone to attracting lightning, and this can damage electrical equipment in your homes.

 Note :  2/4/8 telephone is optional, share same metal box.

Feature:

Extend Telephones and Network: 2/4/8 (optional) Independent telephone lines + 2 Gigabit Ethernet (10/100/1000 Mbit/s) Autosensing port over fiber optic to far end. Gigabit Ethernet connection will over SAME fiber optic along with 2 phones.

Suitable for Both Fiber Types (Single-mode and multimode). Single-mode (SM) fiber for a long distance up to 20 km(12.4miles), Multimode (MM) fiber for a distance up to 500m(0.31miles)

Support Called id & Ring, even Fax Supported. 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.

Simple to Install, Plug and Play, No setup or configuration needed, SC connector for fiber optical port, RJ-11 connector for telephone ports and RJ-45 for Ethernet.

Compact design, Durable Metal. Bilateral heat dissipation. LEDs for power supply and optical fiber link, data status indication can monitor the operating status of the system.
