Abstract:
A hybrid distributed amplification method based on a random fiber laser generated within erbium fiber with low doping concentration, i.e. weak erbium-doped fiber (WEDF), which includes: Step 1. constructing a fiber link via WEDF; Step 2. generating the random fiber laser based on the fiber link, the pump source, the wavelength division multiplexer and the strong feedback module; Step 3. constructing the spatial equalized gain based on hybrid gain of the erbium fiber and random fiber laser; Step 4. the signal is amplified by the hybrid spatial equalized gain. The present invention solves the typical problem of high laser threshold and low pump conversion efficiency when conventional fiber is used to generate random fiber laser for distributed amplification.

Claim (Index 5):
A long-distance optical fiber transmission system based on the method of  claim 1 , comprising a signal transmitter ( 1 ), a wavelength division multiplexer A ( 3 ), a wavelength division multiplexer B ( 6 ) and a signal receiver ( 8 ), which are sequentially connected, and a pump source ( 2 ) and a WEDF ( 5 ), and a strong feedback module ( 4 ); wherein the above pump source ( 2 ), the wavelength division multiplexer A ( 3 ), the strong feedback module ( 4 ) and the WEDF ( 5 ) are sequentially connected to generate random fiber laser; hybrid distributed amplification is performed on the signal by a WEDF and a Raman random fiber laser to achieve long-distance fiber transmission.
