MAFA 5000 Series Erbium Doped Fiber Amplifier (EDFA) Booster

The EMCORE MAFA 5000 Series Micro Erbium Doped Fiber Amplifier (μEDFA) gain block module is an ideal building block for OEM systems integration where there is a requirement to amplify a 1550 nm signal for a broad range of applications including CATV systems, RF/microwave fiber optic links, sensing and control systems, and more. The family of MAFA 5000 EDFA gain blocks is designed to meet the most demanding noise performance requirements of fiber optic communications and control systems, and perform all the functions required of an optical amplifier for system integration.

MAFA 5000 series EDFA gain blocks provide input and output optical isolation for stable, low noise operation. The input and output optical signals are detected for monitoring and control. The input optical signal is amplified with active gain control for a constant output power level or with active output power control for constant gain mode operation.

The MAFA 5000 series EDFA gain blocks also provide monitors and associated alarms for all critical operating parameters. The optical output of the MAFA 5000 series EDFA gain blocks can be split into multiple ports (2, 3 or 4) by an optional internal splitter.

The compact mechanical footprint of the MAFA 5000 allows use of this unit in constrained space environments and high-density applications.
