I-All-Dielectric Self-Supporting (ASU)izintambo ze-fiber optic zimelela ukweqa okusha ekuxhumekeni kwenethiwekhi yangaphandle. Ngomklamo oqinile wemishini, umthamo owandisiwe wokuhlanganisa phakathi kwezigxobo, nokuhambisana ne-aerial, imigudu kanye nokuthunyelwa okuqondile, izintambo ze-ASU zinikeza opharetha ubufakazi obungenakuqhathaniswa besikhathi esizayo kanye nokuguquguquka kwengqalasizinda.
Lesi sihloko sihlola amakhono ekhebula e-ASU abalulekile, izinhlelo zokusebenza zomhlaba wangempela, izindlela zokufaka ezifanele, kanye nendima ethembisayo yalokhu.i-fiber yangaphandleinkundla izodlala ekusekeleni imiphakathi ehlakaniphile yesikhathi esizayo.
I-ASU Cable Design kanye Nokwakheka
Ngenkathi izinhlobo zekhebula le-fiber optic zendabuko zithandaI-ADSSbathembele ekuqinisweni kwensimbi okudidiyelwe kwezinguzu ze-pole-to-pole, izintambo ze-ASU zithola amandla alinganayo ngelungu le-dielectric central strain elenziwe nge-glass-fiber kanye nezintambo ze-aramid noma izinti ze-resin.
Lo mklamo we-all-dielectric uvimbela ukugqwala kuyilapho unciphisa isisindo sekhebula ngobude obunwetshiwe obufika kumamitha angu-180 engasekelwe. I-tensile ilayisha kufika ku-3000N iqinisekisa ukuqina ngisho nasemoyeni onzima nezimo zeqhwa.
Amashubhu esibhafa axegayo afaka imicu engama-250um ngayinye, enikeza isivikelo ngaphakathi kwejeli evimba amanzi noma igwebu. Isakhiwo sonke siqedwa kusetshenziswa ijakhethi ye-HDPE noma ye-MDPE, enikeza ukuqina kuwo wonke amashumi eminyaka okuphila okulindelekile.
Izinto zefayibha ezithuthukisiwe ezifana ne-G.657 yefayibha egobayo nayo iyasetshenziswa ngaphakathi kweshubhu core exegayo, iletha ukusebenza okuphezulu ngaphezu kwezinkulungwane zemijikelezo yokugoba kuzo zonke izindlela zepayipi noma ukufakwa emoyeni.
Ukuguquguquka okungenakuqhathaniswa kwezintambo ze-ASU kuzenza zifaneleke kuzo zonke izindlela zasemoyeni, imigudu kanye nezindlela zokungcwaba eziqondile, ezisekela:
I-Long-Haul Aerial Runs: Njengokushintshwa okuthuthukisiwe kwe-ADSS, izintambo ze-ASU zinikeza ubude besikhathi esinwetshiwe phakathi kwezigxobo zokusabalalisa kuzo zonke izindawo eziyinselele. Lokhu kuvumela ukusebenza kwe-inthanethi okukhulu noma ukuxhumanisa i-backhaul kufika ku-60km.
I-Duct Pathways: Izintambo ze-ASU zifakwa kalula nge-9-14mm-microducts, lulainethiwekhiizakhiwo lapho izindlela ezingaphansi komhlaba zitshaliwe. Ukuvumelana nezimo zabo kusekela ukufakwa kwepayipi elibushelelezi kumabanga amade uma kuqhathaniswa nezintambo ezihlomile.
Ukuxhumana Okungcwatshwe Ngayo: Izinhlobo ze-ASU ezikwazi ukumelana ne-UV zinikeza opharetha indlela engabizi kakhulu yokungcwaba ifayibha emigwaqweni enguthelawayeka, ujantshi, amapayipi noma amanye amalungelo endlela ngaphandle kokudinga indawo ebizayo kakhonkolo. Ukungcwatshwa okuqondile komhlaba kufanela izifunda zasemakhaya.
Imizila Ehlanganisiwe: Izintambo ze-ASU zivumela ukuhlukahluka komzila lapho ushintsha phakathi kwezikhala zasemoyeni, imigudu engaphansi komhlaba kanye nokungcwatshwa okuqondile endaweni eyodwa eqhutshwa ngobude ngokulungisa amasu okwakha.
Izinzuzo ze-ASU Ngaphezu kwe-ADSS
Nakuba bendabukoIzintambo ezizisekelayo ze-All-Dielectric Self-Support (ADSS).Sekuyisikhathi eside isebenzela ukukhishwa kwefayibha yasemoyeni, isiteji sesizukulwane esilandelayo se-ASU sinikeza izinzuzo eziningi:
Ubude Be-Span Esandisiwe: Ngelungu elimaphakathi elilula, elinamandla aphezulu, izintambo ze-ASU zifinyelela ububanzi obungamamitha angu-180 uma kuqhathaniswa namamitha angu-100-140 we-ADSS yefa. Lokhu kunciphisa kakhulu izindleko zokuqiniswa kwezigxobo nokufaka.
I-Corrosion Resistance: Idizayini ye-ASU ye-dielectric yonke isusa insimbi ngokuphelele, ivimbela amaphuzu okuhluleka kwe-oxidation amashumi eminyaka ngaphandle.
Ukuqina Kwezinga Lokushisa Eliphansi: Izintambo ze-ASU zigcina ukuguquguquka kwehle kuye ku--40 Celsius, okuqinisekisa ukwethembeka ngisho nokubanda kakhulu. Izintambo ze-ADSS ziba brittle ngaphansi kuka -20 Celsius.
Usayizi Ohlangene: Ngobubanzi obuncishisiwe, izintambo ze-ASU zinciphisa umthelela obonakalayo kanye nokulayishwa komoya kuyo yonke imizila yasemoyeni ezindaweni zasemadolobheni noma ezifundeni ezizwelayo kwemvelo.
I-DQE Ethuthukisiwe: Ukulahlekelwa kwesignali kuncishisiwe ngenxa yokukhiqiza okunembayo kwamashubhu e-ASU buffer nemicu, okuthuthukisa ukusebenza kokubona.
Ukufakwa Okufanelekile Kwekhebula Le-ASU Esizeni
Ukuze wenze imali ngokugcwele ekuqineni nasekusebenzeni kwezintambo ze-ASU, izindlela zokuphatha nezindlela zokuzifaka ziyadingeka:
Isitoreji: Ama-Reels kufanele ahlale emile futhi engaphakathi endlini kuze kube yilapho kuthunyelwa. Shiya ukupakishwa kwasefekthri kuphelele ngaphambi kokufakwa ukuze uvimbele ukungena kwamanzi.
Ukulungiselela: Ama-schematics kufanele abonise izindlela eziqondile zemisele kanye nezinhlobo zezigxobo zokugijima emoyeni. Qinisekisa ukuthi ama-strand clamp namahange akhona ngokususelwe kusivinini somoya esilindelekile.
Umsebenzi wePole: Ngaso sonke isikhathi sebenzisa ochwepheshe abaqeqeshiwe namaloli amabhakede ukuze usebenze emoyeni. Shiya ikhebula eleqile elanele ezigxotsheni ukuze uvimbele umonakalo ngesikhathi esibi sezulu.
Ukudonsa Ukugcoba: Sebenzisa izibambo zokudonsa kanye nama-dynamometer ukuze uqaphe ukushuba, futhi uhlale ugcoba ukuze unciphise ukungqubuzana phakathi kwamapayipi. Lokhu kugcina ubuqotho besikhathi eside babathwali bezintambo zengilazi.
I-Bend Radius: Gcina irediyasi yokugoba engu-20xD kukho konke ukuphatha nokufaka. Sebenzisa izithungu ezinkulu ze-pulley nomaphi lapho uqondisa kabusha indlela yekhebula.
Ukuhlanganisa: Yenza noma yiziphi izingxenye ezimaphakathi ne-span noma ukunqamula kuphela ezindaweni ezivinjiwe ezivikela isimo sezulu. Qinisekisa ukuthi ama-fusion splicers kanye nochwepheshe baphatha ama-optical splices.
Ukunamathela emikhubeni ehamba phambili kulondoloza ukusebenza kokubona futhi kuthuthukisa ubude bempilo. Xhumana namazinga asemthethweni afana ne-TL 9000 lapho kusebenza khona.Izintambo ze-ASU zimelela inkundla eyinhloko evumela ukuguqulwa kwedijithali kwezifunda emhlabeni wonke. Njengoba amadolobha ahlakaniphile ekhula anesifiso sokuvelela ezinhlosweni zokusimama, izinsizakalo zezakhamizi, ukuphepha kanye nokuthuthukiswa komnotho, ukuxhumana okunesivinini esiphezulu okuba yimpoqo.
Ngokuguquguquka kwesimo sezulu futhi kudinga ingqalasizinda eqinile kuwo womabili amanethiwekhi olayini angenantambo, izintambo ze-ASU zihlinzeka ngokuqina kuzo zonke izindlela zokufaka zasemoyeni, ezingaphansi komhlaba kanye nezingcwatshwe ngokuqondile. Lokhu kuvumelana nezimo kuzonikeza amadolobha amandla obufakazi besikhathi esizayo kanye nokufinyelela kwendawo njengoba ukuhlanganiswa kwe-IoT kushesha. Ukwakhiwa kwe-ASU kuyaqhubeka nokuvela, kuletha ubude besikhathi esinwetshiwe, ukunciphisa ukulayishwa komoya, kanye nokuphila okude okuthuthukisiwe kuzilungiselelo zangaphandle ezinonya kakhulu.
Ukuthi ukuthuthukiswa kokufinyelela ezindaweni zasemaphandleni, ukusebenza kahle kwe-inthanethi phakathi komasipala, noma ukuphatha inqwaba yemithombo yedatha yasemadolobheni, ubuchwepheshe obuzisekelayo be-ASU buthuthukisa imiphakathi ehlakaniphile phezu kokuhlukana kwedijithali.
Izintambo ze-ASU zidambisa izithiyo ezinkulu:
Ukuxhumana Kwasemakhaya: Ezindaweni ezingahlanganisiwe nezikude, izintambo zasemoyeni zigwema izindleko ezinkulu zokudonsa amapayipi. I-ASU inika amandla ukuthunyelwa ngokushesha.
I-Urban Mobility: I-compact footprint kanye nesignesha ephansi ebonakalayo yezintambo ze-ASU kuvimbela ukuphikiswa kobuhle okungabambezela amanethiwekhi abalulekile.
Ukusimama: Ngokulahlekelwa kwesignali ephansi kuzo zonke izikhala ezinwetshiwe, amakhebuli e-ASU anciphisa izidingo zokukhulisa kuyo yonke imizila emide, ehlisa ukusetshenziswa kwamandla.
I-Scalability: Abakhi benethiwekhi bathola ingqalasizinda ekwazi ukukala kalula umthamo ngokuhamba kwesikhathi ngaphandle kokudonsa ikhebula elisha ngenxa yamafayibha amnyama angasetshenzisiwe.
Ngokunikeza ukuguquguquka nokusebenza okuhlukahlukene okudlula ezinye izindlela ezivamile zentambo yefayibha njenge-ADSS,i-ASU ezisekelayoimele ukukhetha okuya phambili kwemiphakathi ephishekela isimo esihlakaniphile kuwo wonke amandla, amanzi, ezokuthutha kanye nemisebenzi yomphakathi.Inkundla yokuxhumana yangaphandle kanye nobungcweti bokusebenzisa obukhethekile manje sekusendaweni yokuxhuma umhlaba ngesivinini esilula.
