RFED-5019-S adopts digital stabilizing microcircuit which ensures detecting SBS value and adjusting optical power online. The double-pump design ensures ultra low noise and less power of pump leak. It has RF signal testing port with low noise. This product is an important relay transmission equipment in 1550nm fiber communication systems and is applied to ultra-long transmission.

Features:
1. Automatically detecting and adjusting SBS value with an intelligent SBS Servo System. It can measure the optimum optical power for the system in accordance with the different fiber type and the lightwave features of signal source. Then the optical power will be saved as the output optical power. It can be used as a headend equipment in long transmission (≥ 60km).

2. Adjusting optical power online with digital stabilizing microcircuit. It has a wide range for adjusting the optical power, so as to meet the demands of your network. It can be used as a standby equipment for the optical amplifier at different optical power.
3. Can choose double-pump design ensuring ultra low noise and less pump leak. We choose the famous brand for the semiconductor pump laser. The EDFA has input/output power detector which can automatically adjust the pump laser, so as to keep a stable output optical power.
4. Low power consumption (≤ 20W) and low temperature rise range, so as to reduce the load on heat-dissipation system in Mechanical Plant Room.
5. Managed by RFNMS (Royal Flyer Network Management System). You can adjust each parameter of this product by remote monitoring.
6. 160*32 matrixes LCD on front panel so as to display every kind of working parameters.
