Ezweni elishintsha ngokushesha lengqalasizinda yezokuxhumana kanye nenethiwekhi, isidingo sezixazululo zekhebula eziqinile, ezingabizi kakhulu, futhi ezilula ukuzifaka asikaze sibe phezulu. Phakathi kwezinketho eziningi ezitholakalayo, Umfanekiso 8 Ikhebula le-Fiber Optic ivelele njengokukhetha okuguquguqukayo nokwamukelwa kabanzi, ikakhulukazi ekufakweni kwezindiza. Lo mhlahlandlela ophelele uhlola ubunzima bezintambo ze-fiber optic ze-Figure 8, uhlola isakhiwo sazo esiyingqayizivele, izinhlelo zokusebenza ezahlukahlukene, imininingwane yobuchwepheshe, kanye nezinzuzo.

Iyini ikhebula le-Fiber Optic le-Figure 8?

Ikhebula le-fiber optic le-Figure 8, elaziwa nangokuthi ikhebula lomoya elizisekelayo, libonakala ngesimo salo esihlukile esifana nenombolo "8". Lo mklamo uhlanganisa izingxenye ezimbili ezibalulekile zibe yiyunithi eyodwa, ehlangene:

1. Isigaba Sezithunywa:Iluphu ephezulu ye-"8" ivame ukuba nentambo yensimbi noma isithunywa sensimbi esigoqekile. Le ngxenye inikeza ukwesekwa okudingekayo komshini kanye namandla okunamathela, okuvumela intambo ukuthi iboshwe phakathi kwezingodo noma ezinye izakhiwo ngaphandle kwesidingo sezintambo ezengeziwe zokusekela.

2. Isigaba Sekhebula Lokukhanya:Iluphu engezansi igcina imicu ye-optical ngokwayo, evikelwe ngaphakathi kwepayipi elixegayo noma i-core ebambekile, ezungezwe amalungu aqinile kanye ne-sheath evikelayo.

Lo mklamo ohlanganisiwe wenza kube lula ukufakwa, unciphise izindleko zabasebenzi, futhi uthuthukise ukuthembeka okuphelele kokufakwa kwefayibha yomoya. Izinhlobo ezivamile zifaka phakathi i-GYTC8S, i-GYTC8A, kanye ne-GYXTC8S, ngayinye eyenzelwe izimo ezithile zemvelo kanye nokubalwa kwefayibha.

Ukubuka Konke Kwesakhiwo kanye Nezingxenye Eziyinhloko

Ukuqonda ukwakheka kwekhebula le-fiber optic le-Figure 8 kubalulekile ukuze kuqashelwe amakhono alo okusebenza. Ake sihlukanise izakhi zalo eziyinhloko:

1. Izinketho Zezintambo Zesithunywa

Intambo yesithunywa iyinsika yekhono lekhebula lokuzisekela. Izinketho zifaka:

• Isilayezi Sensimbi Eyodwa:Ilula futhi ifanelekela ubude obufushane (ngaphansi kwamamitha angu-80-100).

• Isithunywa Sensimbi Ehlanganisiwe:Yakhiwe ngezintambo zensimbi eziningi ezihlanganisiwe (isb., 7x0.3mm, 7x1.0mm), enikeza amandla aphezulu okudonseka ezindaweni ezinde nezindawo ezivame ukuba nomoya omkhulu noma imithwalo yeqhwa.

• Isithunywa se-FRP (i-Fiber Reinforced Plastic):Indlela ehlukile engeyona eyensimbi, efanelekile ezindaweni ezinengozi enkulu yombani noma lapho kudingeka khona ukuhlukaniswa kukagesi.

2. Izakhiwo Zezinsika Zekhebula Elibonakalayo

Imicu ye-optical ivikelwe ngaphakathi kwengxenye engezansi ye-"8". Imiklamo evamile eyinhloko yile:

• Ipayipi Elikhululekile Eliphakathi (isib., i-GYXTC8S):Imicu igcinwe epayipini elilodwa elikhululekile eligcwele ijeli elingangeni manzi. Itholakala nge-armored (ene-corrugated steel tape yokuvikela amagundane nokuchoboza) kanye nezinhlobo ezingezona i-armored.

• I-Layer-Stranged (isb., GYTC8S/GYTC8A):Amashubhu amaningi akhululekile, ngalinye liqukethe imicu, aboshwe eduze kwelungu lamandla eliphakathi. Lokhu kuvumela ukubalwa kwemicu ephezulu (kufika kuma-cores angu-144 noma ngaphezulu) kanye nebhalansi engcono yomshini, okwenza ifaneleke kumanethiwekhi omgogodla.

3. Izendlalelo Nezinto Ezivikelayo

• Izinto Zokuthuthwa Okuxekethile:Ipulasitiki ephezulu ye-modulus, emelana ne-hydrolysis kanye nokucindezeleka kwemvelo.

• Ukuvimba Amanzi:Ukugcwaliswa kwejeli ngamapayipi axegayo kanye nothayela noma iteyipu evuvukala amanzi engxenyeni engaphakathi yekhebula kuvimbela ukungena komswakama.

• Isithiyo Somswakama:I-Aluminium Polyethylene Laminate (APL) ivame ukufakwa eduze kwe-cable core ukuze kuvikelwe umswakama owengeziwe.

• Izinto Zokumboza:

  • I-HDPE (i-Polyethylene Enobuningi Obuphezulu):Izinga elijwayelekile lokusetshenziswa ngaphandle, elinikeza ukumelana okuhle kakhulu kwe-UV kanye nokuqina.

  • I-LSZH (I-Low-Smoke Zero-Halogen):Isetshenziswa ezindaweni lapho ukuphepha emlilweni kubaluleke kakhulu, njengasezindaweni eziseduze nezakhiwo.

  • Izithasiselo Ezivimbela Umlilo:Thuthukisa ukusebenza komlilo ngenkathi ulondoloza ukuguquguquka.

Imininingwane Yobuchwepheshe Nokusebenza

Izintambo ze-fiber optic zesibalo 8 zenzelwe ukuhlangabezana nezindinganiso zokusebenza eziqinile. Imininingwane ebalulekile ifaka:

Isiphetho

Ikhebula le-Figure 8 Fiber Optic liyisisekelo samanethiwekhi e-fiber optic anamuhla asemoyeni, elinikeza inhlanganisela yamandla okusebenza, ukusebenza kahle kokufakwa, kanye nokusebenza kahle kwezindleko. Umklamo walo oyingqayizivele ubhekelela izinhlelo zokusebenza ezahlukahlukene, kusukela ekunwetshweni kwe-broadband yasemakhaya kuya ekuxhumaneni kwasemadolobheni. Ngokuqonda isakhiwo sayo, imininingwane, kanye nezinzuzo, amabhizinisi nabantu ngabanye bangasebenzisa lobu buchwepheshe ngempumelelo futhi baqinisekise ukuthi okuqukethwe kwabo okubalulekile kufinyelela kulabo abafuna ulwazi nezixazululo kulesi sigaba. Njengoba isidingo sokuxhumeka okusheshayo siqhubeka nokukhula, ikhebula le-Figure 8 ngokungangabazeki lizohlala liyingxenye ebalulekile ekwakheni ingqalasizinda yesikhathi esizayo.
