Multiwavelength network access technologies

Abstract

Increased bandwidth and functionality will be offered by WDM networks compared to single wavelength ones, with applications ranging from straightforward capacity enhancement through to switched virtual dark fiber carrying disparate traffic to customers' premises. However, their implementation depends on their capability of offering the users cost effective solutions. This means that WDM equipment must be built small, rugged with low power consumption and high functional density. The network access module (NAM) developed at Nortel as part of the optical networks technology consortium (ONTC) illustrates such integration.
