Low Noise, Hign Gain Pre-Amp EDFA Module (EDFA-PA-LN-M)

Data Sheet

Product Overview

The Optilab EDFA-PA-LN-M Pre-Amp EDFA is a low noise and high-gain module for amplifying low input level signals that is an easy-to-use and cost-efficient solution for photonic subsystems, OEM integration, free space communication ,and satellite/ground link. Using a dual stage design, this module provides over 50 dB gain with maximum 4.5 dB noise figure and is designed to amplify signal with a low input level as low as -60 dBm. Software control is standard via an RS-232/485 port for status monitoring and pump laser protection are designed to ensure the reliability of the device. The EDFA-PA-LN-M requires a single ±5 Volt DC power supply for operation that comes included with each unit. Contact Optilab for more information.
