Dear all,
I have some queries about Er- doped MMF amplifier.
1. Parameters specially core and cladding refractive index of MMF Amplifier must be the same as of MMF link and multimode generator etc for a particular MMF system?
2. I have seen in MMF examples in optisystem that they used pump laser before Er doped MM Amplifier. Can we use this MM amplifier directly without using pump laser as we do use amplifiers in single mode systems.
3. Can we use all other components like filters, power splitter, attenuator etc with MM system?
