      Can anybody tell me the roll off factor of Gain Flattening Filter (GFF)?

      I believe that depends on what the filter has been optimized to and the which interpolation method is used. Try optimizing the filter then using a white light source to view the transmission function. Or simply use an optical test set like the Optical Filter Analyzer or Lightwave Analyzer.
