Ngokweemeko ezisebenzayo, iintambo zamehlo zihlelwa ngokubanzi ngokweendidi ezininzi, kubandakanya ngaphandle, ngaphakathi, nangaphakathi/ngaphandle. Ngowuphi umahluko phakathi kwezi ndidi ziphambili zeentambo zamehlo?
1. Intambo yeFayibha ye-Optical yangaphandle
Olona hlobo luxhaphakileyo lwentambo esidibana nalo kubunjineli bonxibelelwano ludla ngokuba yintambo yangaphandle yefiber optical.
Ukuhlangabezana neemfuno zokusetyenziswa kwemekobume yangaphandle, iintambo zefiber zangaphandle zihlala zisebenza kakuhle ngoomatshini kwaye zihlala zisebenzisa ubungqingqwa bokufuma kunye nezakhiwo ezikwaziyo ukumelana namanzi.
Ukomeleza ukusebenza komatshini wentambo, iintambo zefiber zangaphandle zihlala zibandakanya izinto zentsimbi ezifana namalungu anamandla asembindini wesinyithi kunye neeleya zentsimbi yesikrweqe.
I-aluminiyam egqunywe ngeplastiki okanye iiteyiphu zentsimbi ezigqunywe ngeplastiki ezijikeleze umbindi wentambo zibonisa iimpawu ezintle zokuthintela ukufuma. Ukungangeni kwamanzi kwekhebula kufezekiswa ikakhulu ngokufaka igrisi okanyeumsonto wokuvala amanzinjengezigcwalisi ngaphakathi kwesiseko sentambo.
I-sheath yeentambo zangaphandle ze-optical fiber zenziwe nge-polyethylene. Iishethi zePolyethylene zineempawu ezibalaseleyo zomzimba, ukuxhathisa ukubola, ixesha elide lokuphila, ukuguquguquka okuhle, kunye nezinye iingenelo, kodwa azinqandeli ilangatye. Ikhabhoni emnyama kunye nezinye izongezo zibandakanya ngokubanzi kwi-sheath ukomeleza ukuxhathisa kwayo kwimitha ye-ultraviolet. Ke ngoko, iintambo zefiber zangaphandle esizibonayo zihlala zimnyama ngombala.
2.Indoor Optical Fiber Cable
Iintambo zefiber optical zangaphakathi zidla ngokuba nesakhiwo esingeyontsimbi, enemicu ye-aramid edla ngokusetyenziswa njengelungu lamandla entambo, inegalelo ekwandiseni ukuguquguquka.
Ukusebenza koomatshini kwiintambo zefiber optical zangaphakathi zikholisa ukuba sezantsi kunezo zeentambo zangaphandle.
Umzekelo, xa uthelekisa iintambo zangaphakathi ezenzelwe ukubethelwa nkqo kunye nokusebenza ngcono koomatshini kwiintambo zangaphandle ezisetyenziswa kwindawo ebuthathaka yoomatshini njengemibhobho kunye neentambo zasemoyeni ezingazixhasiyo, iintambo zangaphakathi zinamandla avumelekileyo okubamba kunye namandla avumelekileyo okuthambisa.
Iintambo zefiber optical zangaphakathi zihlala zingadingi ingqwalaselo yokumelana kwamanzi nokuqinisekisa ukufuma, okanye ukuxhathisa kwe-UV. Ngoko ke, ukwakheka kweentambo zangaphakathi zilula kakhulu kuneentambo zangaphandle. Isingxobo seentambo zefiber optic zangaphakathi ziza ngemibala eyahlukeneyo, ehambelana neentlobo zeentambo zefiber optic, njengoko kubonisiwe kumzobo ongezantsi.
Xa kuthelekiswa neentambo zangaphandle, iintambo zefiber zangaphakathi zinezipani ezimfutshane kwaye zihlala zifuna ukupheliswa kuzo zombini iziphelo.
Ngoko ke, iintambo zangaphakathi zivame ukubonakala ngendlela yeentambo zokubopha, apho icandelo eliphakathi liyintambo ye-fiber optical yangaphakathi. Ukuququzelela ukupheliswa, i-fiber cores ye-fiber cores yeentambo zangaphakathi zihlala zineentsinga eziqinileyo ezinobubanzi obuyi-900μm (ngelixa iintambo zangaphandle zihlala zisebenzisa iintsinga ezinemibala ezinobubanzi obuyi-250μm okanye i-200μm).
Ngenxa yokuthunyelwa kwindawo yangaphakathi, iintambo zefiber zangaphakathi kufuneka zibe nesakhono esithile sokunqanda amadangatye. Kuxhomekeka kumlinganiselo wokubuyiswa komlilo, isingxobo sekheyibhile sisebenzisa izinto ezahlukeneyo zokunqanda amadangatye, njenge-polyethylene egatya idangatye, i-polyvinyl chloride,umsi ophantsi zero halogen idangatye-retardant polyolefin, njl.
3.Indoor / Outdoor Optical Fiber Cable
Intambo yangaphakathi / yangaphandle ye-fiber optical, eyaziwa ngokuba yi-universal indoor / outdoor cable, luhlobo lwentambo eyenzelwe ukusetyenziswa ngaphandle nangaphakathi, isebenza njenge-conduit yeempawu zokukhanya ezivela ngaphandle ukuya kwiindawo zangaphakathi.
Iintambo zefiber zangaphakathi / zangaphandle kufuneka zidibanise iingenelo zeentambo zangaphandle ezifana nokuxhathisa ukufuma, ukuxhathisa kwamanzi, ukusebenza kakuhle komatshini, kunye nokuchasana kwe-UV, kunye neempawu zeentambo zangaphakathi, kubandakanywa ukuchithwa komlilo kunye nombane ongasebenziyo. Olu hlobo lwentambo ikwabizwa ngokuba yintambo yenjongo ezimbini yangaphakathi/yangaphandle.
Uphuculo olwenziwe ngaphakathi/ngaphandle kweentambo zefiber optical, ezisekwe kwiintambo zangaphandle, ziquka:
Ukusetyenziswa kwezixhobo ezithintela amadangatye kwi-sheath.
Ukungabikho kwamacandelo esinyithi kwisakhiwo okanye ukusetyenziswa kwezixhobo zokuqinisa isinyithi ezinqanyulwa ngokulula ngombane (njengocingo lomthunywa kwiintambo ezizixhasayo).
Ukuphunyezwa kwemilinganiselo eyomileyo yokuthintela amanzi ukukhusela ukuvuza kwegrisi xa intambo ibekwe ngokuthe nkqo.
Kubunjineli bonxibelelwano oluqhelekileyo, iintambo zangaphakathi/zangaphandle azifane zisetyenziswe ngaphandle kwe-FTTH (IFayibha ukuya eKhaya) iwisa iintambo. Nangona kunjalo, kwiiprojekthi ezibanzi zeekhebhile apho iintambo zokukhanya zidla ngokutshintsha ukusuka ngaphandle ukuya kwindawo yangaphakathi, ukusetyenziswa kweentambo zangaphakathi / zangaphandle zihlala rhoqo. Izakhiwo ezibini eziqhelekileyo zeentambo zangaphakathi / zangaphandle ezisetyenziswa kwiiprojekthi ezibanzi zeekhebhile zibume obukhululekileyo kunye nesakhiwo esithintelweyo.
4.Ngaba iiCables zeFayibha zaNgaphandle zingasetyenziswa ngaphakathi?
Hayi, abanako.
Nangona kunjalo, kubunjineli bonxibelelwano oluqhelekileyo, ngenxa yobuninzi beentambo zamehlo ezifakwa ngaphandle, iimeko apho iintambo zangaphandle zithunyelwa ngokuthe ngqo ngaphakathi endlwini zixhaphake kakhulu.
Kwezinye iimeko, nkqu noqhagamshelo olubalulekileyo olunje ngeentambo zokuwisa kumaziko edatha angundoqo okanye iintambo zonxibelelwano phakathi kwemigangatho eyahlukeneyo yeziko ledatha engundoqo zisebenzisa iintambo zangaphandle zamehlo. Ibeka imingcipheko ebalulekileyo yokhuseleko lomlilo kwisakhiwo, njengoko iintambo zangaphandle zingenako ukuhlangabezana nemigangatho yokhuseleko lomlilo lwangaphakathi.
5.Iingcebiso zokuKhetha iiCables zeFayibha ze-Optical kwiSakhiwo seSakhiwo
Izicelo ezifuna ukuhanjiswa kwangaphakathi nangaphandle: Ukusetyenziswa kwentambo efuna ukuthunyelwa ngaphandle nangaphakathi, njengeentambo zokulahla kunye neentambo ezingena kwisakhiwo, kuyacetyiswa ukuba ukhethe iintambo zefiber zangaphakathi / zangaphandle.
Usetyenziso oluGqwethiweyo Ngaphakathi Ngokupheleleyo: Ukusetyenziswa kweentambo ezifakwe ngokupheleleyo ngaphakathi endlwini, cinga ukusebenzisa iintambo zefiber zangaphakathi okanye zangaphakathi/zangaphandle iintambo zefiber optical fiber.
Ukuqwalaselwa kweeMfuno zoKhuseleko loMlilo: Ukuhlangabezana nemigangatho yokhuseleko lomlilo, khetha ngokucophelela iintambo zefiber zangaphakathi / zangaphandle kunye neentambo ze-fiber optical zangaphakathi ezinemilinganiselo efanelekileyo yokunqanda ilangatye.
Ezi zindululo zijolise ekuqinisekiseni ukuba iintambo ezikhethiweyo zefiber optical fiber zilungele iimeko zazo ezithile zokusasazwa ngaphakathi kweziseko zophuhliso. Bathathela ingqalelo iimfuno zangaphakathi nangaphandle ngelixa bebeka phambili ukuthotyelwa kwemigangatho yokhuseleko lomlilo.
