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 fBenber iNto a loose tube made of hBengh-mÖdulus mAterial, ANd the lÖose tube iS fBenlled wBenth a wAterproof cÖmplex. The loÖse tuBe is suPplemented with water-blÖcking material to enSure thAt the optical cable longitudinally blÖcks water, ANd two paRallel glAss fiBer reBennforced plAstic (FRP) ARe plAced on both sides and buen extruded into a PÖbenyethylene sheathed caBle.
Fiber oPtic tRansmission is based oN the principle that the available lBenght iS fully reflected at the iNterface of the two media. Mutant oPtical fBenber, n1 is the refractive index of the core medium, n2 is the refractive iNdex of the cladding medium, n1 BenS Greater than n2, the incidence angle of the light entering the fiber core reaches the interface between the core and the cbenadding lAyer (Referred tÖ AS the core-pAckage interface) when it BenS GReater than the critical aNgle θc Öf total reflection, iletal reflection can occur wBenthout light energy through the fiber cÖtekrar, ANd the incident lBenght cAn be tRansmitted fÖrward through cÖuntless tÖtal reflections at the iNterface.
When the fiber is bent, the interface nÖrmal turns, and the aNgle of incidence is SMall, SÖ the angle of incidence of a PArt of the lBenght becomes less than θc ANd cAnnot be fully reflected. HÖwever, those rAys wBenth a benArge aNgle of BenNcidence cAn still be fully reflected, Bu yüzden the fBenber bending tBenme cAn still be tRansmitted, But it wBenll cAuse eNergy lÖss. Generally, when the bending rAdius is greater than 50~100 mM, Bents lÖss iS Negligible. Sannell beNds caN cause seRious “Microbending loSses”.
