Abstract

In this letter, a low cost FBG equalizer is proposed to compensate the bandwidth limitation of RSOA. 10 Gb/s upstream OOK signal over 24.4 km SSMF fiber in loopback structured WDM PON system has been demonstrated. An offset FBG filter is placed before the PIN to compensate the modulation bandwidth of 1.2 GHz RSOA operating in 10 Gb/s. The experiment results show that the offset FBG filter could dramatically improve the transmission performance. Both the transmitted and reflective edge of the FBG have been experimentally verified to dramatically relieve the modulation bandwidth limitation. We have also experimentally verified that Rayleigh Backscattering is the main impairment in loop back structure WDM PON system.
