Kuningi ukusetshenziswa kwamakhebuli e-drop fibre optical, futhi izintambo zenethiwekhi nazo zingenye yezindlela ezisetshenziswayo ze-drop fibre optical cables.Kodwa-ke, kunezinkinga ezincane nezincane ekusebenziseni izintambo ze-fiber optical, ngakho ngizoziphendula namuhla.
Umbuzo 1: Ingabe ingaphezulu lekhebula le-fiber optical lithinta ikhwalithi?Ikhebula le-fiber optical lingagcwala kanjani ngaphezulu?
Ubuso bekhebula le-optical wire yesikhumba ngokuvamile lunongqimba lwezinto ezinamafutha, umsebenzi oyinhloko ukufeza umsebenzi wokuvimbela amanzi.Isignali ye-optical idluliselwa ikakhulukazi nge-glass core ngaphakathi, ngakho-ke ngeke ithinte ikhwalithi yokudlulisela.
Umbuzo wesibili: Ikhebula lesikhumba lisetshenziswa njengentambo yenethiwekhi, futhi imbobo yenziwa ekhebula lesikhumba ngesipikili.Ingabe inawo umthelela?
Uma nje ungakwazi ukufinyelela i-Inthanethi ngokujwayelekile, akusho lutho, kodwa ngokuvamile, uma kuyikhebula lesikhumba, kunethuba elikhulu lokuthi lizophuka.Ngokwekhebula le-fiber emhlophe, kunezintambo ezimbili kuphela kanye nentambo yefayibha eyindilinga emnyama.Ama-cores amaningi, uma kusetshenziswa amabili kuphela, amanye ama-cores awasebenzi, mhlawumbe avele adlula ama-cores amabili.
Umbuzo 3. Izintambo ezihlanganisiwe zomphakathi ze-FTTH zidinga ukusetshenziswa kwebhokisi lenethiwekhi elivamile lama-opharetha amathathu.Ibhokisi lenethiwekhi lidinga ikhebula le-fiber optic eyodwa kuphela.Mangaki ama-cores we-sheathed fibre optic cable okufanele ngiwabeke?Ngingayishisela kanjani ikhebula eli sheathed?Yini okufanele ngiyenze ngemuva kokuhlukaniswa kwe-fusion?
Kungabekwa ikhebula elilodwa kuphela, futhi isignali ngayinye inezinhlamvu ezingu-4, futhi ikhebula elingu-12-core lanele.Itheminali yomsebenzisi icushwa ngokuya ngenani.Izintambo ze-Fiber optic zingena ebhokisini le-terminal futhi zihlukaniswa ngamashubhu e-beam, angena kumagridi opharetha.Ukwandisa imojula yokugcina, kunconywa ukubeka ikhebula le-fiber optic ekugcineni.Imuphi u-opharetha okufanele asebenzise i-jumper ukuze agxumele ku-flange yomsebenzisi?Ikhebula le-fiber optic elineshehethi lineshubhu elikhethekile elishwabene ukushisa kanye neshubhu elivikelayo, elixhunywe ku-flange ngemva kokuncibilika.Kulinganiselwa ukuthi ama-opharetha amathathu azodonsa ibhokisi ngemuva, futhi izinto ezinjengokucekela phansi zizokwenzeka.Ngike ngezwa ngalo mkhuba muva nje.Amabhokisi amaningi enethiwekhi abiwayo.Ngemva kwalokho, abanye abantu bangase babangele umonakalo.Izinsiza zibonakala zilondolozwa, futhi sekuvele izinkinga.Ama-FTTH wonke angabasebenzisi be-floor-optical sub-boxes, futhi kukhona amabhokisi okuxhumana nezixhumi ekugcineni komsebenzisi, azophuka kalula.Kunezinsimbi ezikhethekile zokushisela ze-pigtail ne-pigtail fibre optic cable pigtails.Uhlangothi lomsebenzisi lungasebenzisa izintambo ze-butterfly fibre optic ezakhiwe ngaphambili noma izintambo ze-butterfly fibre optic kanye nama-pigtails ukuze ahlanganiswe ngokushisa (ku-fiber optic disk noma kusetshenziswa umkhono wokuvikela oshisayo);Uhlangothi lwezintambo lungethulwa ngamakhebuli amathathu okukhanya omphakathi owodwa, ngalinye lithatha ishubhu elihlukile elixegayo lingene emabhokisini azo futhi lihlanganiswe ne-pigtail (up-link pigtail noma up-link splitter we-optical splitter).
