Telephone over Fiber Extender
128 Port RJ11 Telephone Extender over Fiber Optic
PMD-128PCM-E
the unit can extend your Telephones and Network to remote end through one fiber optic cable, Support 128 channels of Independent telephone RJ11 port and 2 Physical isolated Fast Ethernet (10/100 Mbit/s) RJ45 port over a fiber cable. FC fiber interface, Long working distance up to 20Km by a singlemode fiber cable.
Feature:
1. Suitable for universal singlemode fiber and multimode fiber, Long transmission distance up to 20 km(12miles) over singlemode fiber and up to 500m(0.31miles) over multimode fiber.
2. Lightning protection. No Delay Transmission and Support Protocol: Unlike VoIP products - the extenders transmit signals directly over Optical fiber cables, thus offering NO DELAYS, plus support for fax & legacy applications that is not supported by VoIP lines.
3.FC connector for fiber optical port, RJ-11 connector for telephone ports and RJ-45 for Ethernet. LEDs for power supply and optical fiber link, data status indication can monitor the operating status of the system.
4. Plug and Play, Simple to Install
