G654 fiber optic code

G654:Ultra low loss optical fiber, mainly used for transoceanic optical cable. The common core is pure SiO2,while the ordinary ones need to be doped with germanium. E fibre has emerged as one of the most important fibre technologies for modern long-haul optical communication networks. The loss near 1550nm is minimum, only 0. 185dB/km, the dispersion is relatively large,a bout 17～20 ps/ (nm·km), But the dispersion is. This Recommendation describes the geometrical, mechanical and transmission attributes of a single mode optical fibre and cable which has the zero-dispersion wavelength around 1300 nm wavelength and which is loss-minimized and cut-off wavelength shifted at around the 1550 nm wavelength region.
