ADVANCED OPTICAL-FIBER AND CABLE TECHNOLOGIES - TOWARDS OPTICAL CABLENETWORK INNOVATION

High density optical fiber cable which employs a 16-fiber ribbon compo sed of thinly coated 200 mum outer diameter fiber is being developed A verage optical losses of 0.2 and 0.35 dB have been attained fora 16 an d an 80 single-mode multi-fiber connector, respectively. Cable jointin g time has been reduced to one fifth of that currently required. Reduc tion of structural imperfection loss in optical fibers is tried by mat ching the viscosity of core and cladding materials. The effective inpu t optical power in optical fiber cables is enhanced as much as 7 dB by varying the Brillouin frequency shift along with their length.
