Ikhebula le-optical langaphandle, elibizwa nje ngokuthi ikhebula le-optical lezinga langaphandle, luhlobo lwekhebula le-optical. Libizwa ngokuthi ikhebula le-optical langaphandle ngoba lenzelwe ukusetshenziswa ngaphandle ngqo. Lihlala isikhathi eside, liyakwazi ukumelana nomoya, ilanga, amakhaza, kanye nesithwathwa, futhi linebhokisi langaphandle elijiyile. Liphinde libe nezici zemishini nezendawo ezifana nokumelana nengcindezi, ukumelana nokugqwala, kanye namandla okunamathela.
Izintambo ze-optical zangaphandle ezisetshenziswa kakhulu zihlukaniswe ngezakhiwo ezimbili: uhlobo lwe-central tube kanye nentambo ye-optical yohlobo olusontekile.
① Ikhebula elibonakalayo lohlobo lweshubhu eliphakathi: Isikhungo sekhebula elibonakalayo siyishubhu elikhululekile, futhi ilungu lokuqinisa litholakala eduze kweshubhu elikhululekile. Isibonelo, ikhebula elibonakalayo lohlobo lwe-GYXTW elivamile linenani elincane lama-core, ngokuvamile angaphansi kwama-core ayi-12.
Ikhebula le-Optical le-GYXTW:
Ishubhu le-beam: Izinto zeshubhu le-beam ziyi-PBT, eqinile, eguquguqukayo, futhi emelana nokucindezela kwe-lateral.
Ngenxa yokuthi kunemibala engu-12 kuphela ye-optical fiber, ikhebula le-optical le-standard kazwelonke (futhi elijwayelekile lamazwe ngamazwe) le-center-beam tube lingaba nama-cores angu-12 kuphela. Amakhebula e-optical anama-cores angaphezu kuka-12 avame ukusonteka.
2. Ikhebula Elisontekile Lokukhanya: Izinqwaba eziningana zezintambo ze-optical zisontekile ndawonye zizungeze isici samandla senhliziyo. Lezi zintambo ze-optical, njenge-GYTS, i-GYTA, njll., zingahlanganiswa namashubhu akhululekile ukudala ama-core amakhulu. Inani lezintambo ze-optical.
Izintambo ze-fiber optic ezine-cores ezingama-60 noma ngaphansi zivame ukusebenzisa isakhiwo samashubhu ama-5. Isibonelo, ikhebula le-fiber optic elinama-core angama-60 lisebenzisa amashubhu ama-5, futhi ishubhu ngalinye liqukethe imicu ye-optical eyi-12. Ngokuvamile, izintambo ze-fiber optic ezisontekile ezinama-cores ayi-12 noma ngaphansi zisontekile kanye neshubhu lamashubhu aqukethe ama-cores e-fiber optic ayi-12 kanye nezintambo zokugcwalisa eziqinile ezine. Zingasontekile futhi ngamashubhu ama-2 ane-cores eziyi-6 kanye nezintambo zokugcwalisa ezintathu, noma zihlanganiswe ngezinye izindlela.
Ikhebula Lokukhanya le-GYTS: Phakathi kwezintambo ze-optical ezisontekile, lolu hlobo kanye ne-GYTA yizona ezivame kakhulu. Izinqwaba eziningana zamashubhu zisontekile ndawonye zibe ucingo lwensimbi olujiyile, olune-phosphate. Izikhala ezintanjeni ezisontekile zigcwele i-cable paste evimba amanzi, futhi i-sheath iqiniswa ibe yi-wrapper yangaphandle ngemuva kwesiyingi se-tape yensimbi.
Ikhebula Lokukhanya le-GYTA: Isakhiwo sale khebula lokukhanya sifana ne-GYTS, ngaphandle kokuthi intambo yensimbi ithathelwa indawo yintambo ye-aluminium. Inkomba yokucindezeleka eseceleni yentambo ye-aluminium ayiphakeme njengentambo yensimbi, kodwa intambo ye-aluminium inokumelana okungcono kwe-antioxidant kanye nomswakama. Kwezinye izindawo ezinemibhobho edlulayo, ukusebenzisa imodeli ye-GYTA kuphumela esikhathini eside sentambo yokukhanya.
Ikhebula le-optical lohlobo lwe-GYFTY: Lolu hlobo lwekhebula le-optical luqukethe amashubhu amaningana ahlanganisiwe ajikelezwe ingaphakathi eliqinisiwe elingeyona insimbi. Isikhala esijijekile sigcwele ikhebula elinamathiselwe noma sivikelwe ngetheyiphu evimba amanzi, futhi igobolondo licindezelwa ngqo ngaphandle ngaphandle kwezembatho. Lo modeli unezinhlobo eziningi. Usetshenziswa kwezinye izinhlelo zokusebenza zasemoyeni. Ukuze kwandiswe amandla okudonsa ekhebula le-optical, i-fiber ethile ye-aramid kanye ne-sheath ekhishweyo kuyangezwa ngaphandle kwengaphakathi lekhebula elijijekile. Uma ukuqinisa okuphakathi kungeyona ingaphakathi eliqinisiwe elingeyona insimbi (FRP) kodwa kuyintambo yensimbi, imodeli yi-GYTY, F (emele i-non-metallic).
Ikhebula le-fiber optic lohlobo 53: Sibona amanye amamodeli afana ne-GYTA53 kanye ne-GYTY53. Lo modeli unezela ungqimba lwensimbi kanye nesivikelo kumakhebula e-fiber optic e-GYTA kanye ne-GYTY. Isetshenziswa ezindaweni ezinezimo ezinzima. I-"53" isho ungqimba olwengeziwe lwe-armor kanye nesivikelo.
