• We propose an N-channel power-compensated reconfigurable optical add/drop multiplexer (ROADM) based on using fiber Bragg gratings (FBGs). Both tunable FBGs and wavelength-fixed FBGs are used in this ROADM. By using the dual-pass amplification scheme with two pieces of erbium doped fibers, an 8.0dB optical net gain has been achieved with a gain variation less than ±0.5dB for each add/drop/pass-through channel. System performance was studied for a four-WDM-channel 10Gb/s×100-km lightwave transmission trial network and bit error rate of 10^<-9> is observed for the 50km added signal, 100km pass-through signal and 50km dropped signal at -18.3, -19.4 and -18.9dBm received power, respectively. Only 1.1dB of power penalty was observed compared to the back-to-back transmission.
