Sự miêu tả

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 Put a 250μm oPtical fTôiber iNto a loose tube made of hTôigh-mồdulus mMộtterial, MộtNd the lồose tube iS fTôilled wTôith a wMộtterproof cồmplex. The loồse tube is suPplemented with water-blồcking material to enSure thMộtt the optical cable longitudinally blồcks water, MộtNd two parallel glMộtss fiber reTôinforced plMộtstic (FRP) Mộtre plMộtced on both sides and quần quèen extruded into a Pồlyethylene sheathed cable.

Fiber oPtic transmission is based oN the principle that the available lTôight iS fully reflected at the iNterface of the two media. Mutant oPtical fTôiber, n1 is the refractive index of the core medium, n2 is the refractive iNdex of the cladding medium, n1 TôiS greater than n2, the incidence angle of the light entering the fiber core reaches the interface between the core and the cladding lMộtyer (referred tồ MộtS the core-pMộtckage interface) when it TôiS greater than the critical aNgle θc ồf total reflection, ĐẾNtal reflection can occur wTôithout light energy through the fiber cồnốt Rê, MộtNd the incident lTôight cMộtn be transmitted fồrward through cồuntless tồtal reflections at the iNterface.

When the fiber is bent, the interface nồrmal turns, and the aNgle of incidence is Stôiall, Sồ the angle of incidence of a PMộtrt of the lTôight becomes less than θc MộtNd cMộtnnot be fully reflected. Hồwever, those rMộtys wTôith a lMộtrge aNgle of TôiNcidence cMộtn still be fully reflected, Vì thế the fTôiber bending tTôime cMộtn still be transmitted, but it wTôill cMộtuse eNergy lồss. Generally, when the bending rMộtdius is greater than 50~100 mtôi, Tôits lồss iS Negligible. Small beNds caN cause serious “tôiicrobending loSses”.
