25 dB Gain Pre-Amp EDFA Benchtop (EDFA-PA-B)

Data Sheet

Product Overview

The Optilab EDFA-PA-B Pre-Amp Erbium-Doped Fiber Amplifiers is a high-gain benchtop unit 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. With options for C-band or L-band wavelengths, and using a high gain design, this bench top 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.
