摘要

"Bidirectional optical amplifier device to amplify signals, wavelength division multiplexed by a two-way interleaved.The system of bidirectional optical transmission and process for bi-directional transmission of optical signals.It is presented a device and a process of fibre optic amplifier for a system of wavelength division multiplexing (WDM) which has bi-directional channels are unique and pairsOf the.The apparatus employs optical circulators.Bars of Bragg fiber and fiber doped amplifiers to amplify channels moving in opposite directions in a WDM system to filter noise and ASE noise and retro reflection between the ANCAIS.The interface circulators positioned on opposite ends of the device are respectively odd channels and even moving in opposite directions in the WDM system and get the channelsThrough an amplifier, erbium doped fiber.Other circulators direct the channels amplifiers for two series of bars of Bragg reflecting respectively only the odd channels and pass only the channels pairs or vice versaIn this way filtering - ASE and other noise located between the channels. An additional amplifier can enhance the channels before they leave the apparatus through the interface circulators.
