Overview

The FRM220-FXO/FXS is a POTS (Plain Old Telephone System) over fiber converter/extender. The POTS connection uses a standard RJ-11C modular connector for one copper pair connection. A pair of FRM220-FXO/FXS is required to implement an end to end system. FXO mode connects to a telephone line (PSTN) or PBX station line and has ability to detect ringing voltages and to act as a telephone. FXS mode is the reciprocal unit and has ability to act as PSTN and connects to a telephone device.

POTS voice over fibre with hotline feature

FXO/FXS Modes: Configurable via DIP switch, FXO connects to PSTN or PBX and detects ringing voltages, while FXS acts as PSTN for telephone devices. Two FXS units can create a private "hot line."

Fibre Options: Supports multimode (up to 2 km, e.g., FRM220-FXO-FXS-SC002) and single-mode fibre (up to 30 km for SC030, or 20 km for single-strand BiDi models like SC20A/SC20B). BiDi models (e.g., SC02A/SC02B) use a single fibre strand, halving fibre requirements by using complementary wavelengths (e.g., Tx: 850 nm/Rx: 1310 nm for SC02A, and vice versa for SC02B).
