Transition Networks CAPTF3329-111 POTS to fiber-optic media converter connects central-office voice-grade signals to distant POTS (Plain Old Telephone Service) equipment using standard telephone signaling. It can extend, over fiber, the distance between two voice path communication devices by up to 20 km using single mode fiber cable.
The CAPTF3329-111 provides audio transmission, caller ID, ringing at the distant end and automatic ring-down. Two units are required to implement an end-to-end system. An RJ-11 female connector provides the electrical interface between the media converter and the telephone device. Unit B (CAPTF3329-111), the reciprocal unit to unit A, connects to a telephone device and mimics a Central Office (Customer-Side FXO).
