چکیده
Optical CDMA technology is being explored as a multiplexing technology for high speed access networks, with optical fibre as transmission medium and also processing ie. the spreading/dispreading of the CDMA sequences. For fibre-optic code division multiple access (FO-CDMA) scheme to be a practically implement able one as a high speed access network, two main challenges are, design of (1) codes with high spectral efficiency and cardinality and (2) high speed encoders/decoders which are simple and efficient to implement. As a solution to the first requirement, we have formulated wavelength/time singlepulse-per-row (W/T SPR) codes which are energy efficient and of weight/row WP = 1, for a given weight of the code W, in addition have good 1) cardinality 2) spectral efficiency and minimal 3) correlation values, for given wavelength and time dimensions. In this paper, we have simulated W/T SPR network and also Optical orthogonal codes (OOC) network using a commercially available optical simulation package.

Asynchronous multiplexing schemes are efficient than synchronous schemes, in a bursty traffic environment of multiple access local area network (LAN), as fixed bandwidth is not allocated among the users and there is no access delay. FiberOptic Code-Division Multiple Access (FO-CDMA) is one such asynchronous multiplexing scheme suitable for high speed LAN networks. While FO-CDMA offers potential...
