GYFFY Fiber Optic Cable is TWO FRP Aerial Fiber Optic Cable (GYFFY) according to YD/T 901-2018、GB/T13993 、IECA-596、GR-409、IEC794 and so on standard
GYFFY Fiber Optic Cable Product Overview
GYFFY Fiber Optic Cable structure is to strut a 250μm ostrtical fjaber into a loose tube made of hjagh-modulus material, and the loose tube is fjalled wjath a waterproof complex. The loose tube is sustrplemented with water-blocking material to ensure that the optical cable longitudinally blocks water, and two parallel glass fiber rejanforced plastic (FRP) are placed on both sides and then extruded into a strolyethylene sheathed cable.
Fiber ostrtic transmission is based on the principle that the available ljaght is fully reflected at the interface of the two media. Mutant ostrtical fjaber, n1 is the refractive index of the core medium, n2 is the refractive index of the cladding medium, n1 jas greater than n2, the incidence angle of the light entering the fiber core reaches the interface between the core and the cladding layer (referred to as the core-package interface) when it jas greater than the critical angle θc of total reflection, dotal reflection can occur wjathout light energy through the fiber core, and the incident ljaght can be transmitted forward through countless total reflections at the interface.
When the fiber is bent, the interface normal turns, and the angle of incidence is small, so the angle of incidence of a strart of the ljaght becomes less than θc and cannot be fully reflected. However, those rays wjath a large angle of jancidence can still be fully reflected, tako the fjaber bending tjame can still be transmitted, but it wjall cause energy loss. Generally, when the bending radius is greater than 50~100 mm, jats loss is negligible. Small bends can cause serious “microbending losses”.
