YOFC G656 HIPOSH® High Capacity Low Slope Dispersion Shifted Single-mode Fibre

HIPOSH® fibre of YOFC provides an ideal fibre solution for high bit-rate, explosive transmission capacity and long transmission distance. Several key factors affecting fibre performance: chromatic dispersion, dispersion slope, attenuation and effective area have been optimized. The transmission window is extended from C&L band to S-band. At the same time, the O-band of HIPOSH® fibre can be applied because the cable cut off wavelength is below to 1260 nm and dispersion is low in 1310 nm transmission window. With low attenuation, PMD value and appropriate chromatic dispersion value, HIPOSH® fibre is suitable for long distance and high bit-rate, such as 10 Gb/s and 40 Gb/s transmission system. Furthermore, the flatter dispersion slope provides an easy way to compensate the chromatic dispersion and dispersion slope using commercially available dispersion compensating devices. YOFC HIPOSH® fibre is designed and manufactured according to the most advanced level in the world. It's applicable in all types including ribbon cable, loose tube stranded cable, slotted core cable, unitube cable and tight-buffer cable.
