Network Interface Card for A Bidirectional Wavelength Division Multiplexed Fiber Optic Local Area Network

摘要

In this project a network interface card (NIC) for a fiber optic local area network has been designed and simulated. In the proposed network each NIC has two optical transmitters and receivers on it operating at different wavelengths. This allows the implementation of various network topologies on an optical fiber utilizing dense wavelengths division multiplexing and bidirectional optical add / drop multiplexers For example a ShuffleNet network can be implemented on a single fiber optic ring The ShuffleNet topology minimizes the number of hops through the network for a given data packet. For an eight node network a maximum of three hops is required between any two of the nodes. In this network, control logic routes the data through the network by making decisions regarding transmitter selection. Because routing is performed on the NIC the network control is more distributed than typical when using a central switch or hub. Distributed control along with high data rate transmitters and receivers on each NIC results in high network throughput and low latency. The predicted maximum aggregate throughput for this network is fifty gigabits per second calculated by multiplying the number of transmitters (16) by the data rate of the transmitters (3.125 Gb/s).
