Micro Erbium Doped Fibre Amplifier and pre-Amplifier gain block modules are ideal building blocks for system integrators to extend the fibre link for long-haul signal transport. They are designed to meet the most demanding noise performance requirements of fibre optic communications and control systems and perform all the functions required of an optical amplifier for system integration.
These modules provide input and output optical isolation for stable and low-noise operation. The input and output optical signal power levels 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.
In the pre-Amplifier, the very low level input optical signal is initially pre-amplified, then amplified with active output power control for constant power mode operation and the output optical signal power levels are detected for monitoring and control.
There are compact mechanical footprint EDFAs which allows this unit to be installed in restricted environments.
