Innovative optical fibre for triple play networks
Corning Inc., USA, has recently introduced a new standard single-mode fibre that handles twice the launch power of other ITU-T G.652 fibres, addressing a key technical barrier facing converged voice, video and data services networks (also known as "triple play" networks). The new Corning® NexCor™ optical fibre’s advantage is designed into the optical fibre itself through Corning-engineered MaxPower technology, increasing the stimulated Brillouin scattering (SBS) threshold of the optical fibre by 3dB, which doubles NexCor fibre’s power-handling capability over other standard single-mode fibres. With the ability to launch twice the optical power, network operators can deploy today’s cost-effective analogue video technology with broader network coverage with an outside plant that is more efficiently designed for migration to digital video transmission in the future.
Brillouin scattering is a non-linear effect caused by high-power levels that scatter transmitted light backward (back-scattering) and degrade the signal. Analogue video transmission’s demanding power requirements make a fibre’s SBS threshold the defining limitation of networks delivering analogue video to consumers today, such as passive optical networks (PON) and cable television networks. For example, with twice the launch power enabled by NexCor fibre, a PON can double the number of subscribers served per splitter and extend its reach compared with other standard single-mode fibres. As a standard single-mode fibre, NexCor fibre is fully compatible with Corning® SMF-28e® fibre, the industry standard. The new fibre is ITU-T G.652.D-compliant, meeting or exceeding the most stringent and comprehensive table of specifications.
