    Two main forces behind a lot of interest in the OCDMA techniques are the ability to support asynchronous, bursty data transmission and data access security.To achieve high speed connectivity with a large bandwidth, OCDMA is a highly flexible technique.This paper describes a simulated system for an incoherent OCDMA system using high performance 2-D codes.In this paper we have designed an OCDMA system for 1 Gbps and 1.25 Gbps using (8×4) wavelength hopped-time spreaded 2-D optical codes.The analysis takes into account the effect of data rate for increasing number of users at different length of fibers.The system performance is evaluated by Q-Factor analysis and timing diagram at different data rates i.e. 1 Gbps and 1.25 Gbps Results show that the designed system provides adequate BER (10-9) for 1 Gbps up to 10 users.

    We present TCP/IP throughputs and processor utilizations (both send and receive) obtained for the latest high speed LAN adapter technologies-100 Mbps token ring (with 100 Mbps Ethernet discussed, for comparison) and Gbps (Gigabit) Ethernet-for Microsoft Windows operating systems. Included is a discussion of the factors that influence observed performance, as well as methods for noninvasively measuring and tuning them.
