EDFA Preamplifier Single Channel Amplifier For SDH Networks

Description

Introduction

This Single Channel EDFA Preamplifier is an EDFA (Erbium-Doped Fiber Amplifier) designed specifically for Synchronous Digital Hierarchy (SDH) optical transmission systems. Installed at the receiver side, it significantly enhances receiving sensitivity and extends optical transmission distance, making it ideal for long-haul and metro optical network applications.

The Single Channel Amplifier operates in the C-band (1530–1562 nm) and delivers high gain performance (up to 30 dB depending on configuration) with a low noise figure (typical ≤ 4.5 dB). It supports a wide input power range (-35 dBm to -25 dBm), ensuring stable performance in weak signal environments.

Built for carrier-grade reliability, the device is suitable for SDH, PDH, SONET, and optical Ethernet systems. It also supports flexible network management options and is designed for easy integration into access and metro optical networks.

EDFA Preamplifier Highlights

• Support Telnet for optional
• ASE noise filter & ASE suppression filters
• High Precise ACC (automatic constant current) Circuit as default
• ATC (automatic temperature control) function
• Offering status appearance and diagnosing fault with LCD

Model: BD-SDH-EDFA
