2 Wire POTS Enhanced

Extend Analog Phone Lines Over Fiber With Caller ID – Line Powered

The 2 Wire POTS (Plain Old Telephone Service) Enhanced system provides transmission of standard analog POTS, telemetering, or PBX loop start signals over two optical fibers. The system transmits signals in the voice-frequency or audio range (300Hz-3400Hz) while providing ringing and off-hook detection, and supports caller ID and forward disconnect. Common applications include telephone, fax, and dial-up modems.

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

A complete system uses one CO and one Sub card.

Note: Square wave ringing option is available (SM10). Contact the factory for additional information.
