The present disclosure provides a method for modification of surface of an initial optical fiber preform. The initial optical fiber preform is manufactured using at least one preform manufacturing process. The surface of the initial optical fiber preform is treated with 50-70 liters of chlorine per square meter of the surface of the initial optical fiber preform. The surface of the initial optical fiber preform is flame polished using a flame polishing module. The treatment of the surface of the initial optical fiber preform with chlorine and flame polishing of the surface of the initial optical fiber preform collectively converts the initial optical fiber preform into a modified optical fiber preform.

Method for modification of surface of optical fiber preform

The present disclosure provides a method for arranging a plurality of optical fiber ribbons in an optical fibre cable. The method includes a set of steps. The set of steps include a first step of receiving the plurality of optical fiber ribbons. Moreover, the set of steps include a second step of arranging the plurality of optical fiber ribbons in a plurality of circular arcs in the optical fibre cable. The plurality of circular arcs is substantially parallel.

The present disclosure provides a method for stacking of a plurality of optical fibre ribbons (). The plurality of optical fibre ribbons () is defined by a top surface (S) and a bottom surface (S). The top surface (S) and bottom surface (S) are defined by a plurality of elevated regions and a plurality of groove regions. The method for stacking of the plurality of optical fibre ribbons () includes arranging the plurality of optical fibre ribbons () over each other such that the plurality of elevated regions of each of the plurality of optical fibre ribbons fits over the plurality of groove regions of an adjacent optical fibre ribbon of the plurality of optical fibre ribbons (). In addition, arrangement of the plurality of optical fibre ribbons forms an optical fibre ribbon stack ().

Optical fibre ribbon and optical fibre cables thereof

Embodiments describe an optical fiber that includes a core. The core has high compressive stress. The compressive stress of the core is in a range of about 20 to 60 MPa. The optical fiber further includes a cladding. The cladding is divided into a first cladding layer and a second cladding layer. The second cladding layer has a high residual stress. The high residual stress of the second cladding layer is in a range of about 20 to 60 MPa. The optical fiber enables reduction of particle related breaks. Further, the optical fiber has elevated LLT strength. The LLT strength is about 6 Kg. The optical fiber has high proof test yield. Furthermore, the optical fiber is highly sensitive to micro-bending of the optical fiber.
