I-GL FIBBER, njengeumkhiqizi wekhebula le-fiberngeminyaka engu-21 yokuhlangenwe nakho kokukhiqiza, idinga ukubambisanacabangela izici eziningi lapho ukhetha i-imodeli efanele kanye nokucaciswa kwentambo ye-fiber optic engaphansi komhlaba. Nazi izinyathelo ezibalulekile neziphakamiso:
1. Cacisa izidingo eziyisisekelo
Izinga lokuxhumana nebanga lokudlulisela:Nquma ukuxhumana okudingekayo
izinga le-ion kanye nebanga lokudlulisela ngokuya ngokuhlela kwenethiwekhi ukuze ukhethe ikhebula le-optical yemodi eyodwa efanelekile noma enemodi eminingi. Intambo yokubona yemodi eyodwa ifanelekile f
noma ibanga elide, ukudluliswa kokuxhumana okushesha kakhulu, kuyilapho ikhebula le-multi-mode optical lifaneleka ezimweni ezikude, eziphansi zesicelo.
Ukukhetha inombolo ebalulekile:Inombolo eyinhloko ibhekisela enanini lemicu yokubona ngaphakathiintambo yokubona, ngokuvamile ehlukaniswa ngama-cores angu-2 kuya kwangu-144. Ukukhetha inombolo ewumgogodla efanele ngokwezidingo zangempela kunganciphisa ngempumelelo izindleko zentambo yokubona.
2. Cabangela izici zendawo ezungezile
Izimo zendawo nesimo sezulu:Cabangela isimo sendawo (njengezintaba, amagquma, indawo eyisicaba, njll.) nezimo zezulu (ezifana nezinga lokushisa, umswakama, i-pH yenhlabathi, njll.) yendawo lapho kubekwa khona intambo yokubona. Isibonelo, izindawo ezisogwini zingase zidinge izintambo ezibonakalayo ezingangeni emanzini nezingagqwali; izindawo ezibandayo kakhulu zidinga izintambo zokubona ezinqanda ukuqhwanda kanye nezokugoba.
Izici zemvelo ezikhethekile:Hlola ukuthi ingabe zikhona yini izimo ezikhethekile ezifana nezitimela ezifakwe ugesi ze-AC, olayini bamandla kagesi aphezulu, ukulimala kombani, izinhlekelele zezikhukhula, nokulimala kwamagundane. Lezi zici zingase zibe nomthelela ekukhethweni kwezintambo ezibonakalayo, njengesidingo sokukhetha izintambo ezibonakalayo ezinokuvikela umbani kanye nezindawo ezivikela amagundane.
3. Qonda ukwakheka nokusebenza kwezintambo ze-optical
Isakhiwo se-cable core:Ikhebula le-optical elinesakhiwo se-fiber ye-tube elixekethile linobubanzi obukhulu bokunyakaza kwamahhala ku-casing, okungahle kususe umthelela wokushintsha kwezinga lokushisa futhi lifanele izindawo ezinezinguquko ezinkulu ekushiseni okuzungezile.
Umgodla nezikhali:Khetha i-sheath nempahla yezikhali ezifanele ngokuya ngendawo yokubeka. Isibonelo, isivikelo setheyipu ye-aluminium sidlala indima yokuvikela umswakama we-radial, isivikelo sethayiphu yensimbi sidlala indima ecindezelayo, futhi izembatho zocingo lwensimbi zinikeza izakhiwo eziqinile nezicindezelayo.
Ukugcwalisa amafutha:Ukugcwalisa amafutha kungathuthukisa ukusebenza kobufakazi bomswakama wezintambo ze-optical futhi kugcine ukuzinza kwekhwalithi yokudlulisela.
4. Khetha amamodeli athile
Ngokusekelwe ekuhlaziyweni okungenhla, khetha ngokuhambisana namamodeli ekhebula lokubona emakethe. Okulandelayo amamodeli wekhebula le-fiber optic elingaphansi komhlaba kanye nezici zawo:
Ikhebula yefayibha yohlobo lwe-GYTA53:ukusetshenziswa kwangaphandle, ukugcwaliswa kwamafutha, itheyiphu ye-aluminium egoqwe ngobude be-polyethylene emgodleni wangaphandle, ofanele ukubekwa phezulu nokubeka amapayipi. Inomswakama omuhle nomphumela wokugqwala, kodwa inkomba yengcindezi engemuva ingaphansi kancane kuneyebhande lensimbi.
Ikhebuli yefayibha yohlobo lwe-GYTY53:ukusetshenziswa kwangaphandle, ukugcwaliswa kwamafutha, ibhande lensimbi eligoqwe ngobude be-polyethylene emgodleni ophindwe kabili, umphumela omuhle we-anti-flattening, ofanele indawo yokungcwaba eqondile, izindawo ezinezidingo zomswakama ophezulu noma izidingo eziphezulu zamandla emishini.
Ikhebuli yefayibha yohlobo lwe-GYFTA53:ukusetshenziswa kwangaphandle, ukugcwaliswa kwamafutha, ibhande lensimbi eligoqwe ngobude, i-polyethylene sheath yangaphakathi, i-non-metallic reinforcement, i-aluminium-polyethylene yangaphandle, isisindo esilula, ifanele indawo yokungcwaba eqondile.
Ikhebuli yohlobo lwe-GYTS yefayibha:ngezikhali zebhande lensimbi kanye ne-polyethylene sheath yangaphandle, ehlinzeka ngokuvikeleka okwengeziwe, okufanelekile endaweni yokungcwaba eqondile edinga amandla aphezulu emishini.
5. Cabangela ukunakekelwa kwangemva kwesondlo
Lapho ukhetha izintambo zokukhanya, kufanele futhi unake ukunakekelwa kwazo ukuze zikwazi ukutholakala ngokushesha futhi zilungiswe lapho kwenzeka iphutha. Ngesikhathi esifanayo, landela amazinga afanelekile kazwelonke nawemboni ukuze uqinisekise ukuthi ikhwalithi yephrojekthi ihlangabezana nezidingo zokucaciswa.
Kafushane, ukukhetha imodeli efanele kanye nokucaciswa kwezintambo ze-fiber optic ezingaphansi komhlaba kudinga ukucatshangelwa okuphelele kwezidingo zokuxhumana, izici zemvelo, ukwakheka kwekhebula elibonakalayo nokusebenza, kanye nokugcinwa kwangemuva. Ngokuhlaziya ngokucophelela nokuqhathanisa, imodeli yekhebula ye-optical efanelekile kakhulu ingakhethwa ukuze kuqinisekiswe ukuzinza nokuthembeka kwenethiwekhi yokuxhumana.
