DWDM-Direct Access System Based on the Fiber Bragg Grating Technology

By Oskars Ozoliņš, Vjačeslavs Bobrovs and Ģirts Ivanovs


Our proposed approach for increasing the transmission capacity is to reduce the channel spacing of a DWDM-direct system to the minimum while keeping the employed optical band-pass filter technologies. For the DWDM-direct system with 55 GHz FBG a satisfactory performance is achieved with a 50 GHz channel interval at the 10 Gbit/s data transmission speed leading to the increase of spectral efficiency for overall system from 0.18 bit/s/Hz to 0.2 bit/s/Hz
