Product Overview

The Optilab EDFA-I-M series of Erbium Doped Fiber Amplifiers (EDFA) is a line of high gain, in-line amplifiers for use in HFC, FTTH and DWDM applications. By using a dual stage design, EDFA-I-M provides optical gain up to 40 dB while maintaining low noise figure (NF). EDFA-I-M is a versatile amplifier that can be used for very wide range of input levels.

Depending on the pump laser configuration, EDFA-I-M amplifier produces optical output levels from +16 dBm up to +24 dBm. The EDFA-I-M has dual amplifier consisting of a pre-amp and a power amplifier.
