1. Isigqubuthelo sangaphandle:
1. Ijakethi yangaphandle yeentambo ze-optical zangaphakathi ngokuqhelekileyo yenziwe nge-polyvinyl chloride (PVC), i-polyethylene, okanye i-polyurethane ethintela ilangabi (LSZH). Le jakethi igudile, iyakhazimla, iguquguquka, kwaye kulula ukuyisusa. Ijakethi yangaphandle yeentambo ze-optical ezingaphantsi ayinasiphelo esihle kwaye ithambekele ekunamatheleni kwimicu eqinileyo kunye nemicu ye-aramid.
2. Ingqokelela yangaphandle yeentambo ze-optical zangaphandle kufuneka yenziwe nge-polyethylene emnyama ekumgangatho ophezulu (i-HDPE, i-MDPE). Nje ukuba intambo yenziwe, ingqokelela yangaphandle mayibe bushelelezi, ikhazimle, ibe nobukhulu obufanayo, kwaye ingabi namaqamza. Ingqokelela yangaphandle yeentambo ze-optical ezingaphantsi yenziwe kakhulu ngezinto ezisetyenzisiweyo. Ingqokelela yangaphandle yeentambo ze-optical ezingaphantsi irhabaxa ngenxa yamanqanaba aphezulu okungcola (uthuli lwelayisi) kwizinto eziluhlaza, nto leyo ebangela imingxunya emininzi emincinci kwingqokelela yangaphandle yentambo. Ukuba ingqokelela yangaphandle yentambo ye-optical igobile ngokuphindaphindiweyo, iya konakala kwaye ibe mhlophe. Emva kokuba intambo ye-optical ifakwe ixesha elithile, ingqokelela yangaphandle iya kuqhekeka kwaye ivumele amanzi ukuba angene.
2. Iifayibha zokukhanya:
Abavelisi beentambo ze-optical eziqhelekileyo basebenzisa ii-cores zefayibha ze-Class A ezivela kubavelisi abaphambili. Iintambo ze-optical ezingabizi kakhulu nezisemgangathweni ophantsi zihlala zisebenzisa iifayibha ze-Class C, Class D, kunye neefayibha ezingafunekiyo ezingaziwayo ukuba zivela phi. Ezi fayibha zinemithombo enzima kwaye bezingekho kwifektri ixesha elide. Zihlala zimanzi kwaye zitshintsha umbala, kwaye iifayibha ze-multimode zihlala zixutywa neefayibha ze-single-mode. Iifektri ezincinci ngokubanzi azinazo izixhobo zokuvavanya ezifunekayo kwaye azinakuvavanya umgangatho weefayibha. Ezi fayibha azibonakali ngokubona kuphela. Iingxaki eziqhelekileyo ezifunyanwa ngexesha lokwenziwa ziquka: i-bandwidth encinci kakhulu kunye nomgama omfutshane wokuhambisa; ubukhulu obungalinganiyo, obuthintela uqhagamshelo kwi-pigtail; kunye nokungabikho kokuguquguquka, okwenza ifayibha ithambekele ekuqhekekeni ngexesha lokujijeka.
3. Ucingo lwentsimbi oluqinisiweyo:
Iintambo zentsimbi kwiintambo ze-fiber optic zangaphandle eziqhelekileyo zi-phosphated kwaye zinomphezulu ongwevu. Olu hlobo lwentambo yentsimbi alunyusi ilahleko ye-hydrogen emva kokufakwa, alugqwali, kwaye lunamandla aphezulu okutsalwa. Iintambo ze-fiber optic ezikumgangatho ophantsi zenziwe ikakhulu ngeentambo zentsimbi ebhityileyo okanye ze-aluminium. Ezi zinokubonwa ngembonakalo yazo emhlophe kunye nenyaniso yokuba zinokugotywa lula xa zibanjwe ngesandla. Iintambo ze-fiber optic ezenziwe ngezi ntlobo zeentambo zentsimbi ziya kuvelisa ilahleko eyongezelelweyo ye-hydrogen kwixesha elizayo, kwaye ngokuhamba kwexesha, iziphelo ezimbini zeebhokisi ze-fiber optic ziya kunyibilika kwaye ziqhekeke.
4. Ibhanti yentsimbi enesikrweqe:
Abavelisi abaqhelekileyo basebenzisa imicu yentsimbi esongiweyo ende egqunywe ngeplastiki enamacala amabini, exutyiweyo, nengagqwaliyo. Iintambo ze-optical eziphantsi zenziwe ngamashiti esinyithi aqhelekileyo, kwaye ngokuqhelekileyo icala elinye kuphela eliye lanyangwa ukuthintela umhlwa.
5. Ibhokisi ye-fiber optic:
Ityhubhu ekhululekileyo ejikeleze i-optical fiber kwi-optical cable kufuneka yenziwe ngezinto ze-PBT. Ezi zinto zinika amandla aphezulu, ziyamelana nokuguquguquka, kwaye ziyamelana nokuguga. Ii-optical cable housings eziphantsi zihlala zenziwe nge-PVC. Ububanzi bangaphandle bezi housings buncinci kakhulu kwaye buthambile, buthambile lula xa bucinezelwe. Zifana neestraw zokusela kwaye aziboneleli ngokhuseleko olufanelekileyo kwi-optical fiber.
6. Ioyile yefayibha:
I-fiber paste esetyenziswa kwiintambo ze-optical zangaphandle inokuthintela ukutyibilika kwesilivere, ukulahleka kwe-hydrogen, kwanokuqhekeka kwe-fiber optic okubangelwa kukufuma. I-fiber paste encinci kakhulu esetyenziswa kwiintambo ze-optical ezingaphantsi, kwaye amanye amaqamza anokubonakala emehlweni. Kungenjalo, kusetyenziswa i-inferior fiber paste, nto leyo enciphisa ubomi beentambo ze-fiber optic.
7. I-Aramid:
Ikwabizwa ngokuba yiKevlar, ifayibha ye-aramid yifayibha yamakhemikhali enamandla aphezulu ngoku esetyenziswa kakhulu kwishishini lezomkhosi. Isetyenziselwa ukuvelisa izigcina-ntloko zomkhosi kunye neevesti ezikhusela iimbumbulu. Okwangoku, ifayibha ye-aramid ethengiswayo ikakhulu ivela kwi-brand yaseMelika iDuPont. Iintambo ze-optical zangaphakathi neze-overhead (ADSS) zisebenzisa i-aramid yarn njenge-reinforcement. Ngenxa yexabiso eliphezulu le-aramid (200,000 yuan/ton), iintambo ze-optical zangaphakathi ezikumgangatho ophantsi zihlala zine-diameter encinci kakhulu yangaphandle, enokonga iindleko ngokunciphisa ubungakanani bentambo ye-aramid esetyenzisiweyo. Olu hlobo lwentambo ye-optical lonakala lula xa ludlula kwi-conduit.
8. Intambo yokuncamathisela:
Intlama yangaphandle yentambo ye-fiber optic ibotshelelwe ngaphandle kwesingxobo se-fiber optic ukukhusela intambo kumswakama. Intlama yentambo esemgangathweni ophezulu ixutywe ngokulinganayo kwaye ayihlukani emva kokusetyenziswa ixesha elide. Kwiintambo ze-optical ezikumgangatho ophantsi, intlama yentambo iya kutsha okanye isizalisi asiyi kwanela, nto leyo echaphazela ukusebenza kwentambo okumelana nokufuma.
