64Ch POTS(FXO/FXS)Telephone over Fiber Mux
64Ch POTS Telephone over Fiber Overview
The E-Link 64-Channel POTS-to-Fibre Converter is a high-density solution for modernising legacy
telephone infrastructure. This powerful extender can transmit up to 64 traditional analogue phone lines
(POTS/PSTN) over a single fibre optic cable, enabling long-distance communication with crystal-clear voice quality.
The system comprises two units: an FXO unit for connecting to central office (PSTN) or PBX station lines,
and an FXS unit for connecting to standard analogue telephone devices. Key features include robust ring
voltage detection, superior signal integrity and standard RJ11 connectors for seamless integration
with existing copper-based equipment. This converter is the perfect future-proof solution
for telecoms operators, enterprises and campuses looking to leverage the reliability
and capacity of fibre while preserving their investment in analogue phones and fax machines.
