Mini Erbium Doped Fiber Amplifier

SKU: MEDF

The Mini Erbium-doped fiber amplifier (MEDF) features a miniature size. It is built using semiconductor lasers, WDM, isolator, and erbium-doped fiber. The product has the advantages of high reliability, high gain, and low noise. It uses an uncooled pump laser to achieve low power consumption. It works up to 100GHz data rate. It can monitor and adjust the output optical power in real-time and can support real-time output LOS alarm and pump protection. An adapting PCB provides convenience to be powered and interfaced with USB with a user-friendly GUI.
The MEDFs have both ACC mode ‒ automatic or constant current control and APC mode ‒ automatic power control settable via GUI. In the ACC mode, the pump laser’s current is set by the user and automatically locked by the EDFA to achieve a constant pumping current. The EDFA’s output power is proportional to the input power and has output even though the input signal is weak. In the APC mode, the user sets the output power, and the EDFA automatically maintains the output constant in a feedback laser pump control way. When the input optical power fluctuates, the APC mode minimizes the output power fluctuation and is suitable for power type and line type EDFA. The default setting is APC.
The EDFA has isolators on both input and output.
