Extend an Analog DID Trunk Line Over Fiber

Product Overview


The 2 Wire DID (Direct Inward Dialing) fiber link card system provides a fiber optic transmission of a Telco DID TRUNK line to a PBX (loop start) over two optical fibers.

The signal provided over copper wiring is converted to optical, transmitted over fiber optic cable, and converted back into the original copper-based signal at the other end. This allows for network extension over long distances, and provides electrical isolation between both ends.

The 2-wire DID system transmits signals in the voice-frequency or audio range (300Hz-3.4KHz) while providing reverse battery signaling to communicate call status. The 2 Wire DID system is temperature hardened for tough environmental conditions where 24/7/365 operation and rugged reliability are critical, and is covered by our Limited Lifetime Warranty.

This fiber link card is designed to be installed into any of the RLH Fiber Link Card Housings, and occupies a single card slot.
