FXO & FXS over Fiber Multiplexer Solution

Reliable Voice Extension over Long Distances

Overview

The FXO and FXS over Fiber Multiplexer Solution enables transparent transmission of analog voice signals over optical fiber, making it ideal for extending telephony services across long distances without signal loss or noise.

By converting FXO/FXS voice interfaces into optical signals, the solution ensures secure, stable, and high-quality communication between geographically separated locations.

What Are FXO and FXS?

• FXS (Foreign Exchange Station): Provides dial tone, battery power, and ringing to analog telephones and fax devices.
• FXO (Foreign Exchange Office): Receives dial tone from PBX/PSTN lines and connects to telephone exchanges.

The fiber multiplexer transports these FXO/FXS signaling channels over single-mode or multi-mode fiber, maintaining full signaling transparency.

How the Solution Works

• Analog FXO/FXS signals connect to the fiber multiplexer.
• The multiplexer converts electrical voice to optical signals.
• Optical signals travel over fiber for tens of kilometers.
• At the remote end, signals convert back to analog and connect to PBX/PSTN/analog devices.

Key Features

• Supports multiple FXO and FXS channels on a single fiber
• Long-distance transmission without EMI interference
• Plug-and-play deployment – no complex configuration
• Low latency with stable HD-quality voice
• Point-to-point / ring topology support
• Suitable for industrial and mission-critical applications

Applications
