Detailed Product Description

4Ch POTS(FXO/FXS)Telephone over Fiber Mux

4Ch POTS Telephone over Fiber Overview

The E-Link 4-Channel POTS-to-Fibre Converter provides high-density transmission for up to

four traditional telephone lines via a single optical fibre, thereby maximising infrastructure efficiency

and significantly reducing cabling costs. This robust Voice over Fibre solution uses standard

RJ-11 connectors to integrate easily and reliably with existing copper wiring. The system operates

using matched FXO and FXS units: the FXO interface connects to central office (PSTN)

or PBX trunk lines and has full ringing voltage detection capability, while the reciprocal FXS unit

connects directly to end-user telephone devices and provides complete dial tone

and calling functions. Designed for exceptional clarity and immunity to electromagnetic interference,

this extender is ideal for scaling legacy voice services across campuses, remote facilities

and secure industrial applications.

4Ch POTS Telephone over Fiber Features

Standard RJ11 telephone interface for easy connection
4 voice channels with support for Caller ID and Fax services
Dual voice port design (O port & S port):
- O port connects to the switch

Compatible with FXO/FXS standard telephones
Supports point-to-point, cascaded, and distributed networking without SNR degradation
Fiber optic power link with LED indicators for system status monitoring
Industrial-grade modular design for flexible deployment, reliability, and durability
