Paper Abstract

The multimedia communication needs high-performance, cost- effective communication techniques to transport data for the fast-growing multimedia traffic resulting from the recent deployment of World Wide Web (WWW), media-on-demand , and other multimedia applications. To transport a large volume, of multimedia data, high-performance servers are required to perform media processing and transfer. Typically, the high- performance multimedia server is a massively parallel processor with a high number of I/O ports, high storage capacity, fast signal processing, and excellent cost- performance. The parallel I/O ports of the server are connected to multiple clients through a network switch which uses parallel links in both switch-to-server and switch-to- client connections. In addition to media processing and storage, media communication is also a major function of the multimedia system. Without a high-performance communication network, a high-performance server can not deliver its full capacity of service to clients. Fortunately, there are many advanced communication technologies developed for networking, which can be adopted by the multimedia communication to economically deliver the full capacity of a high-performance multimedia service to clients. The VCSEL array technology has been developed for gigabit-rate parallel optical interconnections because of its high bandwidth, small-size, and easy-fabrication advantages. Several firms are developing multifiber, low-skew, low-cost ribbon cables to transfer signals form a VCSEL array. The OC12 SONET data-rate is widely used by high-performance multimedia communications for its high-data-rate and cost- effectiveness. Therefore, the OC12 VCSEL parallel optical interconnection is the ideal technology to meet the high- performance low-cost requirements for delivering affordable multimedia services to mass users. This paper describes a multimedia OC12 parallel optical interconnection using a VCSEL array transceiver, a multifiber ribbon cable, and MT connectors to achieve a high-performance, low-cost parallel link. A logical model of a multimedia server with parallel connections to an ATM switch, and to clients is presented. The design of the parallel optical link is analyzed. Furthermore, the link configured for testing, the test method, and test results are presented to confirm the analysis and to assure reliable link performance.
