Abstract
In this paper, the dispersion compensation for 4*10 Gb/s, 400 km G.652 fiber by chirped optical fiberBragg grating (FBG) is introduced. For the first time, we have measured and compensated the polarizationmode dispersion (PMD) of FBG, which in each channel is less than 1.1 ps. When the bit error rate (BER)is 10^(-10) and the bit error is zero, the transmission power penalty of each channel is less than 2 dB, andthe best result is negative which means that the receiver sensitivity is increased after transmission.
