2Ch POTS(FXO/FXS)Telephone over Fiber Mux
2Ch POTS Telephone over Fiber Overview
The E-Link 2-Channel POTS-to-Fibre Converter reliably extends two separate traditional telephone
lines (POTS) over a single optical fibre, significantly increasing
capacity and cost efficiency.
Designed for seamless integration, it features standard RJ-11
connectors for straightforward
copper pair termination. The system operates alongside
complementary units: the FXO model interfaces
with central office (PSTN) or PBX trunk lines and features ringing
voltage detection.
The reciprocal FXS model connects directly to telephone sets, fax
machines or modems,
providing dial tone and functionality as the line source. This
robust solution is ideal for securing
and extending critical voice communications to remote buildings,
campuses and industrial sites,
offering superior clarity and immunity to interference.
2Ch POTS Telephone over Fiber Features
Standard RJ11 telephone interface for universal compatibility
2 voice channels with support for Caller ID and Fax transmission
Dual voice port design (O port & S port):
Compatible with FXO/FXS standard telephones
Supports point-to-point, cascaded, and distributed networking with no SNR degradation
Fiber optic power link with status LEDs for real-time system health monitoring
Industrial-grade modular design ensures flexible deployment, high reliability, and durability
