The increasing complexity of optical processing algorithm has led to the need of developing the algorithms specifications using software implementation that became in practice the reference implementation. Adapting the algorithm specified by such software models into architectures becomes a very resource consuming and memory intensive task. The key objective in this paper is to develop analytical models to analyze the effects of various parameters such as propagation distance, chirping factor on the received power at the receiver end. SSF algorithm is simulated using MATLAB
TM
on Intel[R]
TM
Core[TM] 2 Duo CPU T5470 @ 1.60GHz, 0.99GB of RAM. Analysis show the received output power reduces by 61.1% with 5 time increase in chirping factor. Increase in chirp decreases the received power and broadens the received pulse. A reduction of 82% of received power is observed as the propagation distance increases by 50Kms. Mapping of SSFM algorithm to architecture is done with this analysis. The algorithm is synthesized using Xilinx design Manager. The hardware is implemented using virtex XC5VLX30TFF655 FPGA device family with speed grade -6. The complete hardware operates with maximum frequency 20.982
Mhz
which uses total memory of 523564
