Abstract

The rapidly growing Internet traffic are driving the demands for higher transmission capacity and higher processing speed, especially for the backbone networks. To support such bandwidth usage an optical Fiber Distributed Data Interface Wavelengtg Division Multiplexed (FDDI/WDM) network is proposed, wherein the wavelength channels are amplified using Erbium-Doped Fiber Amplifiers (EDFA's) to compensate for the losses over the optical fiber span. In this paper we investigate the network performance for both asynchronous and synchronous transmissions by measuring the amplified spontaneous emission (ASE) along the ring, the optical signal to noise ratio (OSNR) and the electrical SNR at different destinations. The effects of various network parameters such as synchronous bandwidth allocation and Target Token Ration Time (TTRT) on the network perfomrance are also presented. Results show that when FDDI is used in conjunction with WDM higher throughut and less delay are simutaneously achieved in comparison with FDDI standard networks.
