Inline Erbium-Doped Fiber Amplifier, Benchtop (EDFA-I-B)

Data Sheet

Product Overview

The Optilab EDFA-I-B Erbium-Doped Fiber Amplifier (EDFA) is a high gain, inline amplifier for the research and development of optical networks. By using a dual amplifier design, EDFA-I-B provides optical gain of up to 40 dB while maintaining low noise figure (NF). EDFA-I-B is a versatile amplifier that can be used for very a range of input levels. Depending on the pump laser configuration, EDFA-I-B amplifier produces optical output levels from +18 dBm to +25 dBm with an input power level range from -15 dBm to +5 dBm.
