Advanced Fused Fibre Devices

Abstract Regular fused fibre device performance is affected by the environment in various ways - so much so that these effects are exploited in some sensors to measure vibration (sound), temperature, pressure etc. Of course, in optical communications systems these effects are undesirable and great care has to be taken in manufacture, packaging and mounting to avoid problems. Using advanced fusing techniques, Comcore has developed fused fibre devices that exhibit ultra-high reliability, novel designs and very high, consistent performance. Press Release BBN International announces the Comcore range of advanced fused fibre couplers including: SM, MM, PM, hybrid and plastic (POF) fibres Ultra-high reliability High temperature Ultra-low tap ratios ~0.001% Very low excess loss ~0.02dB Very tight channel spacing WDMs ~70nm. Tree and star NxM couplers up to 16 x16 Meet the most demanding standards Telcordia 1221. Employing Superfusion™, Unifusion™ and Microbend™ techniques on precision custom designed, automated fusion machines, Comcore produce some of the highest specification fused fibre devices in the World. Applications include PON, EDFAs, submarine, fibre lasers and general telecommunications. Follow this link for more information on our web site.
