Design and Implementation of the Dual-wavelength Fiber Ring Network using WDM Technique

In this paper,an optical network interface card with PCI bus peak bandwidth transmission rate has been designed and implemented.Hardware routing and synchronous pipelining transmission have been accomplished to decrease communication latency.Dual wavelength rings have been designed with wavelength division multiplexing to expand the network scale.Optical signals coupling and splitting are achieved through all passive components.Wavelength routing is achieved by optical detector,which can selectively receive the optical signals with different wavelengths.This network structure can be expanded to multi wavelength rings.
