25 dB Gain Pre-Amp EDFA Module, C-band (EDFA-PA-M)

Data Sheet

Product Overview

The Optilab EDFA-PA-M Pre-Amp EDFA is a high-gain module for amplifying low input level signals that is an easy-to-use and cost-efficient solution for photonic subsystems, OEM integration, and fiber optic system integration. Using a high gain design, this module provides over 25 dB gain with a 4.5 dB noise figure and is designed to amplify signal with a low input level as low as -40 dBm. Software control is standard via an RS-232 port for status monitoring and pump current adjustments, and pump laser protection and alarms are equipped to ensure the reliability and safety of the device. The EDFA-PA-M requires a single ±5 Volt DC power supply for operation that comes included with each unit.
