Optical Components for the Global FTTx Market
Worldwide deployments of FTTx systems have accelerated dramatically over the last two years. While many factors contribute, including the regulatory environment and competition with the cable TV industry, this acceleration would not have been possible without the ability of the optical components industry to supply very high performance devices at a cost sufficient for deployment to millions of homes. We examine the technology, performance and economics of two key components for Passive Optical Network (PON) based FTTx systems: passive splitters and triplexer transceivers. In the case of splitters, Planar Lightwave Circuit (PLC) technology has enabled splitters to meet the insertion loss, PDL and uniformity requirements of FTTx systems in volume manufacturing. The first generation of triplexer transceivers has utilized the manufacturing scale achievable globally to meet the cost targets for initial deployments, while a second generation triplexer based on PLC technology promises further improvements.
