Efficient Solution to Bimodal Propagation Effects in Low-Cost 850nm Radio over G.652-Fibre Systems

摘要

Commercial couplers designed for 1550nm are conveniently adopted for realizing efficient Radio-over-Fiber links operating at 850nm on the standard G.652 single mode fiber. In particular, exploiting the mode filtering properties observed in these couplers when excited at 850nm, a multi-wavelength system over the standard G.652 fiber is obtained, opening the possibility to easily integrate in currently developed infrastructures such low cost systems operating in the first optical window.
