Discontinued-MAFA 1014-PA Optical Preamplifier

EMCORE’s MAFA 1014-PA Optical Preamplifier Erbium Doped Fiber Gain Block Module is an ideal building block for system integrators to extend the fiber link for long-haul signal transport. The MAFA 1014-PA Optical Preamplifier series gain blocks are designed to meet the most demanding noise performance requirements of fiber optic communications and control systems and performs all the functions required of an optical preamplifier for system integration.

The MAFA 1014-PA Optical Preamplifier provides output optical isolation for stable, low noise operation. The output optical signal power level is detected for monitoring and control. The very low level input optical signal is amplified with active output power control for constant current mode operation.

The compact mechanical footprint of the MAFA 1014-PA Optical Preamplifier allows using this unit to be installed in small space environments.
