Fiber Optic Isolation Systems - 2 Wire POTS
2 Wire POTS
 

NEBS Level 3The 2 Wire POTS (Plain Old Telephone Service) system provides transmission of standard analog phone, telemetering, or PBX loop start signals over two optical fibers. The system transmits signals in the voice-frequency or audio range (300Hz~3500Hz) while providing ringing and off-hook detection. Common applications include telephone, faxes, and dial-up modems.

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

A complete system uses one CO and one Sub card.

Note: Special modifications are available for forward disconnect (SM07) and square wave ringing (SM10). Contact the factory for additional information.
