Ftth Fiber Optic Sensor Amplifier , High Reliability Optical Signal Booster
Fiber Optic Sensor Amplifier Summary
With the implementation of Broadcast Whole-Optical-Network Transmission Fiber To The Home projects (FTTH), When EDFA is used as a Cascading Magnification Device in the CATV system, the C/N system will deteriorate seriously, So the EDFA should have High Saturation Output Power and Low Distortion, Then EYDFA(Erbium-Ytterbium-Doped Optical Amplifier) double cladding High Power Optical Amplifier can perfectly meet the demand of the nowadays FTTH and FTTB networks.
