Applications of DWDM optical technologies in multiservice broadband HFC network dynamic picture

DWDM optical technology permeates multiservice broadband hybrid fibre coaxial (HFC) networks in all elements of large metropolitan architectures. They were deployed as their performance matched the stringent requirements of the broadband services delivered in baseband digital and FDM analog/digital format and as they became a cost-effective alternative to other solutions. The continuous progress in DWDM optical components makes the broadband HFC networks more cost-effective to deploy and maintain (lower operational cost) and increases their end-to-end capacity.
