Optical network access module technology and integration

WDM networks offer potentially increased bandwidth and functionality when compared to single wavelength ones, with applications ranging from straight forward capacity enhancement through to switched virtual dark fiber carrying separate traffic to the customers' premises. Networks get put in the ground on the basis of cost-effectiveness, this means WDM equipment must be small and rugged with low power consumption and high functional density. Array electronics, optoelectronics and optoelectronic integrated circuits (OEICs), necessary to ensure the viability of WDM networks, have been developed by the ONTC (Optical Technology Network Consortium) and incorporated into the first NAM (Network Access Module) prototype.
