| 简介 |
The present invention refers to a rare-earth element doped fiber optics based Raman amplification and relates to composite optical amplifier, in particular Raman amplifying a residual left after the waste pumping storehouse is connected with a web page to a rare-earth element doped pumping storehouse via optical fibers to a recycling amplifier to be removed over the entire surface a the photocells are is down set from the bridge.
Of the present invention Raman amplification and a rare-earth element doped fiber optics based composite an optical amplifier Raman amplification pumping surplus left after the SnO 2 by incidence signal amplification to produce a rare-earth element doped optical fiber; separated from said surplus pumping storehouse Raman amplifier a wavelength division multiplexing system; and said wavelength division multiplexing system (WDM) lasing in amplifier are placed between one optical isolator inhibiting the effect (light isolator); includes.
Therefore, Raman amplification and a rare-earth element doped fiber optics based of the present invention composite optical amplifier excess Raman pump around the same is cartridge of the existing method excess pumping storehouse waste so that they show efficiency of a total energy the piezoelectric pump can have high efficiency, overall gain bandwidth. can be pulled. A Raman amplification optical fiber for compensating dispersion in addition of a rare-earth element doped and Raman amplification on the gain medium of fiber optics based by the these construction amplifier computing system for converting analog data into the dispersion compensation, signal amplification and efficient pumping storehouse can be geometry simultaneously use. |
