Izintambo ze-optical zangaphakathi zivame ukusetshenziswa ezinhlelweni zezintambo ezihlelekile. Ngenxa yezici ezahlukahlukene ezifana nendawo yokwakha kanye nezimo zokufakwa, ukwakheka kwezintambo ze-optical zangaphakathi sekuyinkimbinkimbi kakhulu. Izinto ezisetshenziselwa imicu ye-optical kanye nezintambo ziyahlukahluka, kanti izakhiwo zemishini neze-optical zigcizelelwa ngendlela ehlukile. Izintambo ze-optical ezivamile zangaphakathi zifaka izintambo zegatsha elilodwa, izintambo ezingahlanganisiwe, kanye nezintambo ezihlanganisiwe. Namuhla, i-ONE WORLD izogxila kolunye lwezinhlobo ezivame kakhulu zezintambo ze-optical ezihlanganisiwe: i-GJFJV.
Ikhebula le-GJFJV langaphakathi
1. Ukwakheka Kwesakhiwo
Imodeli ejwayelekile embonini yamakhebula e-optical angaphakathi yi-GJFJV.
Ikhebula le-optical langaphakathi le-GJ — Ukuxhumana
F — Ingxenye yokuqinisa engeyona eyensimbi
J — Isakhiwo sefayibha yokukhanya esiqinile
V — Isigqoko se-Polyvinyl chloride (PVC)
Qaphela: Ngokuqanjwa kwezinto zeshelufu, u-"H" umele ishelufu elingena-halogen enomsi ophansi, kanti u-"U" umele ishelufu le-polyurethane.
2. Umdwebo Wesigaba Esinqamula Ikhebula Lokukhanya Langaphakathi
Izinto Zokwakheka Nezici
1. I-Optical Fiber Ehlanganisiwe (Yakhiwe nge-optical fiber kanye nesendlalelo sokumboza sangaphandle)
I-optical fiber yenziwe ngezinto ze-silica, kanti ububanzi obujwayelekile bokumboza buyi-125 μm. Ububanzi obuyinhloko bemodi eyodwa (B1.3) buyi-8.6-9.5 μm, kanti bemodi eminingi (OM1 A1b) buyi-62.5 μm. Ububanzi obuyinhloko bemodi eminingi ye-OM2 (A1a.1), OM3 (A1a.2), OM4 (A1a.3), kanye ne-OM5 (A1a.4) buyi-50 μm.
Ngesikhathi senqubo yokudweba i-glass optical fiber, kufakwa ungqimba lwe-elastic coating kusetshenziswa ukukhanya kwe-ultraviolet ukuvimbela ukungcoliswa uthuli. Lokhu kuhlanganiswa kwenziwa ngezinto ezifana ne-acrylate, irabha ye-silicone, kanye ne-nylon.
Umsebenzi wengubo ukuvikela ubuso be-optical fiber ekuswakameni, igesi, kanye nokuhuzuka komshini, kanye nokuthuthukisa ukusebenza kwe-microbend ye-fiber, ngaleyo ndlela kuncishiswe ukulahlekelwa okwengeziwe kokugoba.
Isembozo singafakwa umbala ngesikhathi sokusetshenziswa, futhi imibala kufanele ivumelane ne-GB/T 6995.2 (Okuluhlaza okwesibhakabhaka, okuwolintshi, okuluhlaza okotshani, okunsundu, okumpunga, okumhlophe, okubomvu, okumnyama, okuphuzi, okunsomi, okupinki, noma okuluhlaza okotshani). Kungahlala kungafakwanga umbala njengemvelo.
2. Isendlalelo se-Tight Buffer
Izinto zokwakha: I-polyvinyl chloride (PVC) enobungani nemvelo, evimbela ilangabi,i-polyolefin engena-halogen ephansi (LSZH), ikhebula elivimbela ilangabi elilinganiselwe yi-OFNR, ikhebula elivimbela ilangabi elilinganiselwe yi-OFNP.
Umsebenzi: Ivikela kakhulu imicu ye-optical, iqinisekisa ukuthi iyakwazi ukuzivumelanisa nezimo ezahlukahlukene zokufakwa. Inikeza ukumelana nokucindezelwa, ukucindezelwa, nokugoba, futhi ihlinzeka nangokumelana namanzi nomswakama.
Ukusetshenziswa: Isendlalelo se-tight buffer singafakwa ikhodi yombala ukuze kuhlonzwe, ngamakhodi ombala ahambisana nezindinganiso ze-GB/T 6995.2. Ukuze kuhlonzwe okungejwayelekile, kungasetshenziswa amasongo ombala noma amachashazi.
3. Izingxenye Zokuqinisa
Izinto:Intambo ye-Aramid, ikakhulukazi i-poly(p-phenylene terephthalamide), uhlobo olusha lwefayibha yokwenziwa yobuchwepheshe obuphezulu. Inezakhiwo ezinhle kakhulu njengamandla aphezulu kakhulu, i-modulus ephezulu, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, ulula, ukuvikela ukushisa, ukumelana nokuguga, kanye nokuphila isikhathi eside. Emazingeni okushisa aphezulu, igcina ukuzinza, ngesilinganiso sokuncibilika esiphansi kakhulu, ukukhukhuleka okuncane, kanye nokushisa okuphezulu kokuguquka kwengilazi. Iphinde inikeze ukumelana nokugqwala okuphezulu kanye nokungaqhubi kahle, okwenza kube yinto efanelekile yokuqinisa izintambo ze-optical.
Umsebenzi: Intambo ye-Aramid ijikeleziswa ngokulinganayo noma ibekwe ngobude esikhumbeni sekhebula ukuze inikeze ukwesekwa, ithuthukise ukumelana kokuthamba kwekhebula kanye nokucindezela, amandla omshini, ukuzinza kokushisa, kanye nokuzinza kwamakhemikhali.
Lezi zici ziqinisekisa ukusebenza kahle kokudlulisa ikhebula kanye nokuphila kwenkonzo yalo. I-Aramid isetshenziswa kakhulu ekukhiqizeni amavesti angenazinhlamvu kanye namaparashuti ngenxa yamandla ayo amahle kakhulu okubamba.
4. Umgodla Wangaphandle
Izinto zokwakha: I-polyolefin (LSZH) engenamusi ophansi, i-polyvinyl chloride (PVC), noma izintambo ezivimbela umlilo ezilinganiselwe yi-OFNR/OFNP. Ezinye izinto ze-sheath zingasetshenziswa ngokwezidingo zamakhasimende. I-polyolefin engenamusi ophansi kumele ihlangabezane nezindinganiso ze-YD/T1113; i-polyvinyl chloride kufanele ihambisane nezindinganiso ze-GB/T8815-2008 zezinto ze-PVC ezithambile; i-polyurethane ye-thermoplastic kufanele ihlangabezane nezindinganiso ze-YD/T3431-2018 zama-elastomer e-thermoplastic polyurethane.
Umsebenzi: Igobolondo langaphandle lihlinzeka ngesivikelo esengeziwe semicu ye-optical, okuqinisekisa ukuthi ingakwazi ukuzivumelanisa nezimo ezahlukahlukene zokufakwa. Liphinde linikeze ukumelana nokucindezelwa, ukucindezelwa, nokugoba, ngenkathi linikeza ukumelana kwamanzi nomswakama. Ezimweni zokuphepha okukhulu komlilo, izinto ezingenayo i-halogen entuthu encane zisetshenziselwa ukuthuthukisa ukuphepha kwekhebula, ukuvikela abasebenzi emagesini ayingozi, umusi, namalangabi uma kwenzeka umlilo.
Ukusetshenziswa: Umbala we-sheath kufanele uvumelane nezindinganiso ze-GB/T 6995.2. Uma i-optical fiber iwuhlobo lwe-B1.3, i-sheath kufanele ibe phuzi; kohlobo lwe-B6, i-sheath kufanele ibe phuzi noma iluhlaza; kohlobo lwe-AIa.1, kufanele ibe phuzi; uhlobo lwe-AIb kufanele lube mpunga; uhlobo lwe-A1a.2 kufanele lube luhlaza okotshani; kanye nohlobo lwe-A1a.3 kufanele lube phuzi.
Izimo Zohlelo Lokusebenza
1. Isetshenziswa kakhulu ezinhlelweni zokuxhumana zangaphakathi ezakhiweni, njengamahhovisi, izibhedlela, izikole, izakhiwo zezimali, izitolo ezinkulu, izikhungo zedatha, njll. Isetshenziswa kakhulu ekuxhumekeni kwemishini emakamelweni eseva kanye nokuxhumana nabasebenzi bangaphandle. Ngaphezu kwalokho, izintambo ze-optical zangaphakathi zingasetshenziswa ekuxhunyweni kwenethiwekhi yasekhaya, njenge-LAN kanye nezinhlelo zasekhaya ezihlakaniphile.
2. Ukusetshenziswa: Izintambo ze-optical zangaphakathi zincane, zilula, zigcina isikhala, futhi kulula ukuzifaka nokuzinakekela. Abasebenzisi bangakhetha izinhlobo ezahlukene zezintambo ze-optical zangaphakathi ngokusekelwe ezidingweni ezithile zendawo.
Emakhaya ajwayelekile noma ezindaweni zamahhovisi, izintambo ze-PVC ezijwayelekile zangaphakathi zingasetshenziswa.
Ngokusho kwe-GB/T 51348-2019 ejwayelekile kazwelonke:
1. Izakhiwo zomphakathi ezinokuphakama okungamamitha ayi-100 noma ngaphezulu;
②. Izakhiwo zomphakathi ezinokuphakama okuphakathi kwamamitha angu-50 kuya kwangu-100 kanye nendawo engaphezu kuka-100,000㎡;
③. Izikhungo zedatha zebanga B noma ngaphezulu;
Lezi kufanele zisebenzise izintambo ezibonakalayo ezivimbela ilangabi ezinesilinganiso somlilo esingaphansi kwebanga le-B1 elingenantuthu ephansi, elingenayo i-halogen.
Ezingeni le-UL1651 e-US, uhlobo lwekhebula elivimbela ilangabi eliphakeme kakhulu yikhebula elibonakalayo elilinganiselwe yi-OFNP, elenzelwe ukuzicisha ngaphakathi kwamamitha ama-5 uma livezwa ilangabi. Ngaphezu kwalokho, alikhiphi intuthu enobuthi noma umhwamuko, okwenza lifaneleke ukufakwa emigudwini yokungenisa umoya noma ezinhlelweni zokucindezela zokubuyisa umoya ezisetshenziswa emishinini ye-HVAC.
