Recent Developments in Optical-CDMA
The success and widespread use of CDMA in the wireless domain has renewed interest in exploring its use in the optical domain, which, however, presents a different set of challenges and rewards. A broadband network based on Optical-CDMA has the advantage of using codes like telephone numbers, as opposed to wavelength in a WDM network, to determine connectivity and address network OAMP. Whereas WDM networks have been around for more than a decade, it is now that some laboratory results are showing Optical-CDMA is not just a myth. In this talk we review recent progress in Optical-CDMA and its feasibility for telecom and datacom applications. In particular we shall highlight Telcordia's vision and progress in addressing such problems as low spectral efficiency, multi-user interference and exposure to network impairments.
