Resumen
We demonstrate a novel distributed fiber Raman amplified bus
topology used for WDM transmission over 35 km of single-mode fiber by
use of a multiwavelength Raman pump laser and eight Fiber Bragg gratings
(FBGs). This topology reduces the number of addressing wavelengths
needed at the head of the bus. Furthermore, by relocating the FBGs’
wavelengths of a first section, it is obtained power transpa ...

We demonstrate a novel distributed fiber Raman amplified bus
topology used for WDM transmission over 35 km of single-mode fiber by
use of a multiwavelength Raman pump laser and eight Fiber Bragg gratings
(FBGs). This topology reduces the number of addressing wavelengths
needed at the head of the bus. Furthermore, by relocating the FBGs’
wavelengths of a first section, it is obtained power transparency at the end
of the overall bus, without requiring any additional pump source. We show
how the topology allows the received powers from the first section sensors
to be equalized and partially amplify the overall network. We investigate
how the performance depends on the launched pump power. Results
obtained with this new configuration are compared with those achieved in a
previously reported optically amplified bus topology. [--]
