METHOD AND SYSTEM FOR REDUCING ATTENUATION IN OPTICAL FIBER
Abstract: a method of drawing an optical fiber may include directing an optical fiber comprising an alkali dopant through an inlet of a slow cooling device to a first zone within the slow cooling device and cooling the optical fiber in the first zone, wherein a first residence time tof the optical fiber in the first zone may be greater than or equal to 0.03 sec. the method may further include directing the optical fiber from the first zone to a second zone within the slow cooling device and cooling the optical fiber in the second zone, wherein a second residence time tin the second zone may be greater than the first residence time t. a rayleigh scattering coefficient of the optical fiber drawn may be less than 0.75 db/km*micron, and an attenuation of the optical fiber drawn may be less than 0.16 db/km at 1550 nm.
