This research includes a simulation of optical code division multiple access system
transceiver (OCDMA) of the spectral amplitude coding (SAC). The study investigates the
effect of the pulse generator type used in the transmitter SAC-OCDMA of direc
t detection
technique and the effect of the length of the optical fiber on the signal quality factor (Q)
and on the bit error ratio( BER) . In addition a comparison is made between the SACOCDMA
system of direct detection technique and another one of complementary
subtraction technique in terms of signal quality factor and the bit error ratio when using
the same parameters for both systems.
