Cascading Magnification High Power Optical Amplifier For Fiber To The Home Projects
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.
