Multiple carrier analog transmission system with Er³⁺doped planar optical waveguide amplifiers

摘要

We report for the first time the use of two types of Er³⁺ planar optical waveguide amplifiers in 77 channel CATV fiberlinks. Single and novel composite amplifiers in the headend and incascade allow high quality broadcast transmission in terms of CNR, CTBand CSO over 52 km of standard allwave^TM fiber
