1. Isembozo sangaphandle:
1. Ijakethi yangaphandle yezintambo ze-optical zangaphakathi ngokuvamile yenziwe nge-polyvinyl chloride (PVC), i-polyethylene, noma i-polyurethane evimbela ilangabi (LSZH). Ijakethi yangaphandle ibushelelezi, iyacwebezela, iyaguquguquka, futhi kulula ukuyikhumula. Ijakethi yangaphandle yezintambo ze-optical eziphansi ayinawo umkhawulo omuhle futhi ithambekele ekunamatheleni emicu egobile kanye ne-aramid.
2. Igobolondo langaphandle lezintambo ze-optical zangaphandle kumele lenziwe nge-polyethylene emnyama esezingeni eliphezulu (i-HDPE, i-MDPE). Uma ikhebula selibunjiwe, igobolondo langaphandle kufanele libe bushelelezi, likhazimle, libe nobukhulu obufanayo, futhi lingabi nama-bubbles. Igobolondo langaphandle lezintambo ze-optical eziphansi lenziwe ngokuyinhloko ngezinto eziphinde zasetshenziswa. Igobolondo langaphandle lezintambo ze-optical eziphansi liqinile ngenxa yamazinga aphezulu okungcola (uthuli lwe-lime) ezintweni zokusetshenziswa, okuholela ezimbobeni ezincane eziningi esikhwameni sangaphandle sekhebula. Uma igobolondo langaphandle lekhebula le-optical ligobile ngokuphindaphindiwe, lizolimala futhi libe mhlophe. Ngemva kokuba ikhebula le-optical lifakwe isikhathi esithile, igobolondo langaphandle lizoqhekeka futhi livumele amanzi ukuthi angene.
2. I-fiber optics:
Abakhiqizi bezintambo ze-optical ezijwayelekile basebenzisa ama-core e-fiber e-Class A avela kubakhiqizi abaphambili. Izintambo ze-optical ezingabizi kakhulu nezisezingeni eliphansi zivame ukusebenzisa izintambo ze-Class C, Class D, kanye ne-contract fibers ezingaziwa ukuthi zivelaphi. Lezi zintambo zinemithombo eyinkimbinkimbi futhi bezilokhu zingaphandle kwefektri isikhathi eside. Zivame ukuba manzi futhi zishintshe umbala, futhi izintambo ze-multimode zivame ukuxutshwa nezintambo ze-single-mode. Izimboni ezincane ngokuvamile azinazo imishini yokuhlola edingekayo futhi azikwazi ukuhlola ikhwalithi yezintambo. Lezi zintambo azibonakali ngokubona. Izinkinga ezivamile ezihlangana nazo ngesikhathi sokukhiqiza zifaka: i-bandwidth encane kakhulu kanye nebanga elifushane lokudlulisa; ukujiya okungalingani, ukuvimbela ukuxhumana ne-pigtail; kanye nokuntuleka kokuguquguquka, okwenza intambo ithambekele ekuqhekekeni ngesikhathi sokugoqa.
3. Ucingo lwensimbi oluqinisiwe:
Izintambo zensimbi ezintanjeni ze-fiber optic ezijwayelekile zangaphandle zi-phosphated futhi zinobuso obumpunga. Lolu hlobo lwentambo yensimbi alukhulisi ukulahlekelwa yi-hydrogen ngemva kokufakwa, alugqwali, futhi lunamandla aphezulu okudonseka. Izintambo ze-fiber optic ezisezingeni eliphansi zenziwe ngokuyinhloko ngezintambo zensimbi ezincane noma ze-aluminium. Lezi zingabonakala ngokubukeka kwazo okumhlophe kanye neqiniso lokuthi zingagobeka kalula uma zibanjwe esandleni. Izintambo ze-fiber optic ezenziwe ngalezi zinhlobo zezintambo zensimbi zizokhiqiza ukulahlekelwa okwengeziwe kwe-hydrogen esikhathini esizayo, futhi ngokuhamba kwesikhathi, izinhlangothi ezimbili zamabhokisi e-fiber optic zizoncibilika futhi ziqhekeke.
4. Ibhande lensimbi elihlomile:
Abakhiqizi abajwayelekile basebenzisa imichilo yensimbi egoqwe ngobude eboshwe ngepulasitiki enamacala amabili, ebhulashiwe, engagqwali. Izintambo ezikhanyayo eziphansi zenziwe ngamashidi ensimbi ajwayelekile, futhi ngokuvamile uhlangothi olulodwa kuphela oluye lwaphathwa ukuze kuvinjelwe ukugqwala.
5. Ibhokisi le-fiber optic:
Ishubhu elikhululekile elizungeze i-optical fiber ekhebula le-optical kumele lenziwe ngezinto ze-PBT. Lezi zinto zinamandla aphezulu, zimelana nokuguquguquka, futhi zimelana nokuguga. Izindlu zekhebula le-optical eziphansi zivame ukwenziwa nge-PVC. Ububanzi bangaphandle balezi zindlu buncane kakhulu futhi buthambile, buyathamba kalula uma bucindezelwa. Zifana notshani bokuphuza futhi azinikezi isivikelo esanele se-optical fiber.
6. Amafutha e-fiber:
I-fiber paste esetshenziswa ezintanjeni ze-optical zangaphandle ingavimbela ukuminyana kwesiliva, ukulahleka kwe-hydrogen, ngisho nokuphuka kwe-fiber optic okubangelwa umswakama. I-fiber paste encane kakhulu esetshenziswa ezintanjeni ze-optical eziphansi, futhi amanye amabhamuza angase abonakale ngamehlo enyama. Ngaphandle kwalokho, kusetshenziswa i-inferior fiber paste, efinyeza kakhulu isikhathi sokuphila kwezintambo ze-fiber optic.
7. I-Aramid:
Eyaziwa nangokuthi i-Kevlar, i-aramid fiber iyi-fiber yamakhemikhali enamandla aphezulu esetshenziswa kakhulu embonini yezempi. Isetshenziselwa ukukhiqiza izigqoko zempi namavesti angenazibhamu. Njengamanje, i-aramid fiber emakethe ivela kakhulu kumkhiqizo waseMelika i-DuPont. Izintambo ze-optical zangaphakathi neze-overhead (ADSS) zisebenzisa i-aramid yarn njengokuqinisa. Ngenxa yezindleko eziphezulu ze-aramid (200,000 yuan/ton), izintambo ze-optical zangaphakathi ezisezingeni eliphansi zivame ukuba nobubanzi obuncane kakhulu bangaphandle, obungonga izindleko ngokunciphisa inani lentambo ye-aramid esetshenziswayo. Lolu hlobo lwentambo ye-optical lonakala kalula lapho ludlula ku-conduit.
8. Ukunamathisela ikhebula:
I-fiber paste yangaphandle yekhebula le-fiber optic iboshelwe ngaphandle kwesikhafu se-fiber optic ukuvikela ikhebula ekuswakeni. I-fiber paste yekhwalithi ephezulu ixutshwe ngokulinganayo futhi ayihlukani ngemva kokusetshenziswa isikhathi eside. Ezintambo ze-optical zekhwalithi ephansi, i-fiber paste izonyamalala noma i-filler ngeke yanele, okuthinta ukusebenza kwekhebula okuvikela umswakama.
