YOFC photonic single-mode fibres are specially developed for optical components with strict requirement for bending resistance properties. The fibres are manufactured by PCVD process with Ge/F co-doped material system and special waveguide structure. The fibres have tight geometric and optical specifications. They are compatible with G.652 fibre and has excellent macro-bending performance which makes it very appropriate for the mini components. The fibres meet the standards of ITU-T G.657.A1/G.657.A2/G.657.B3 and suits full range applications from 1260nm to 1625nm.
The Ge/F co-doped material system, design provides excellent macro-bending attenuation and good fused-taper performance. The macro-bending performance of PH1011-C and PH1012-A has been significantly improved with special "trench" waveguide structure and meets the requirements of G.657.A2 and G.657.B3 standards. PH1012-A is specially developed for very small bending radius and compact components and modules in C band with excellent bending resistance.
