Abstract This paper develops a performance model of an optically interconnected parallel computer system operating in a distributed shared memory environment. The performance model is developed to reflect the impact of low level optical media access control and optical device switching latency on high level system performance. The photonic network is based on a passive star-coupled structure th...

Different switching techniques have been proposed to design optical switch architectures. Wave Division Multiplexing (WDM) techniques were extensively investigated to implement switching. Code Division Multiple Access (CDMA) permits multiple users to access bandwidth simultaneously and asynchronously via spread spectrum. This paper presents a non-blocking multiprotocol switch architecture based...

We propose and demonstrate a fiber Bragg grating (FBG) sensor network employing the code division multiple access (CDMA) technique to identify information from individual sensors. To detect information without considering time delays between sensors, a sliding correlation method is applied, in which two different signals with the same pseudo-random binary sequence (PRBS) pattern, but slightly d...

A new multiple access protocol is developed for optical local area networks based on a passive star topology. The protocol uses wavelength division multiplexing (WDM), and combines the advantages of both random-access and scheduled-access sharing schemes, e.g., fixed pre-assigned TDMA and WDM, into a protocol that is highly bandwidth-efficient. No central control is required among users, and th...

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 ...
