Iintambo zangaphakathi zangaphakathi zisetyenziswa ngokuqhelekileyo kwiinkqubo ze-cabling ezicwangcisiweyo. Ngenxa yezinto ezahlukeneyo ezifana nokusingqongileyo kwesakhiwo kunye neemeko zofakelo, uyilo lweentambo ze-optical zangaphakathi ziye zanzima ngakumbi. Izinto ezisetyenziselwa i-fiber optical kunye neentambo ziyahlukahlukana, kunye neempawu zomatshini kunye ne-optical zigxininiswe ngokwahlukileyo. Iintambo eziqhelekileyo zangaphakathi zangaphakathi ziquka iintambo zesebe ezingundoqo, iintambo ezingadityaniswanga, kunye neentambo ezidityanisiweyo. Namhlanje, IHLABATHI ELINYE liza kugxila kwenye yezona ntlobo zixhaphakileyo ze-bundled optical cables: GJFJV.
GJFJV Indoor Optical Cable
1. Ukubunjwa koLwakhiwo
Imodeli esemgangathweni yoshishino lweentambo zangaphakathi zangaphakathi yi-GJFJV.
GJ - Unxibelelwano intambo yangaphakathi yangaphakathi
F - Inxalenye yokuqinisa intsimbi
J - Ulwakhiwo lwefiber optical optical-buffered
V - i-Polyvinyl chloride (PVC) sheath
Qaphela: Xa kuthethwa ngemathiriyeli ye-sheath, "H" imele i-low-halogen-free sheath, kwaye "U" imele i-polyurethane sheath.

Izinto zokuqulunqa kunye neempawu
1. I-Fiber ye-Optical Coated (Ihlanganiswe nge-fiber optical kunye ne-coating yangaphandle layer)
I-fiber optical yenziwe ngezinto ze-silica, kunye ne-standard cladding diameter yi-125 μm. I-core diameter ye-single-mode (B1.3) yi-8.6-9.5 μm, kunye ne-multi-mode (OM1 A1b) yi-62.5 μm. I-core diameter ye-multi-mode OM2 (A1a.1), i-OM3 (A1a.2), i-OM4 (A1a.3), kunye ne-OM5 (A1a.4) yi-50 μm.
Ngexesha lokudweba kweglasi ye-fiber optical, umaleko we-elastic coating usetyenziswa kusetyenziswa ukukhanya kwe-ultraviolet ukukhusela ukungcoliswa ngothuli. Olu tyaba lwenziwe ngezinto ezifana ne-acrylate, irabha ye-silicone, kunye nenayiloni.
Umsebenzi wokugquma kukukhusela umphezulu wefiber optical kufuma, irhasi, kunye nokuqhawuka koomatshini, kunye nokuphucula ukusebenza kwe-microbend yefiber, ngaloo ndlela kuncitshiswa ilahleko eyongezelelweyo yokugoba.
Ingubo inombala ngexesha lokusetyenziswa, kwaye imibala kufuneka ihambelane ne-GB / T 6995.2 (Blue, Orange, Green, Brown, Gray, White, Red, Black, Yellow, Purple, Pink, okanye Cyan Green). Isenokuhlala ingenambala njengendalo.
2. Umaleko we-Buffer oQinisekileyo
Izixhobo: Ihambelana nokusingqongileyo, i-polyvinyl chloride engatshiyo emlilweni (PVC),Umsi ophantsi we-halogen-free (LSZH) polyolefin, intambo ye-OFNR-iqondo lokuyeka ilangatye, intambo ye-OFNP-umlinganiselo we-flame-retardant.
Umsebenzi: Ikhusela ngakumbi imicu ye-optical, iqinisekisa ukuguquguquka kwayo kwiimeko ezahlukeneyo zokufakela. Inika ukuchasana noxinzelelo, uxinzelelo, kunye nokugoba, kwaye ikwabonelela ngamanzi kunye nokuxhathisa ukufuma.
Ukusetyenziswa: I-tight buffer layer ingaba nombala-coded ukuchongwa, kunye neekhowudi zombala ezihambelana nemigangatho ye-GB / T 6995.2. Ukuchonga okungaqhelekanga, iiringi ezinombala okanye amachaphaza anokusetyenziswa.
3. Ukuqinisa Amacandelo
Izinto:Umsonto weAramid, ngokukodwa i-poly(p-phenylene terephthalamide), uhlobo olutsha lwe-high-tech fiber synthetic fiber. Ineepropathi ezigqwesileyo ezinje ngokuqina okuphezulu, imodyuli ephezulu, ukumelana nobushushu obuphezulu, iasidi kunye nokumelana nealkali, ukukhanya, ukugquma, ukumelana nokuguga, kunye nobomi benkonzo ende. Kumaqondo obushushu aphezulu, igcina uzinzo, ngesantya esisezantsi kakhulu sokushwabana, ukukhasa okuncinci, kunye nobushushu obuphezulu beglasi. Ikwabonelela ngokuxhathisa okuphezulu kwe-corrosion kunye nokungaqhubeki, okwenza kube yinto efanelekileyo yokomeleza iintambo ze-optical.
Umsebenzi: Umsonto we-Aramid ujikeleze ngokulinganayo okanye ubekwe ixesha elide kwi-cable sheath ukubonelela ngenkxaso, ukunyusa ukuqina kwentambo kunye nokumelana noxinzelelo, amandla omatshini, ukuzinza kwe-thermal, kunye nokuzinza kweekhemikhali.
Ezi mpawu ziqinisekisa ukusebenza kokuhanjiswa kwentambo kunye nobomi benkonzo. I-Aramid ikwasetyenziswa ngokuqhelekileyo kwimveliso yeevesti zembumbulu kunye neeparashuti ngenxa yokuqina kwayo okubalaseleyo.
4. Isingxobo sangaphandle
Izixhobo: Umsi ophantsi we-halogen-free flame-retardant polyolefin (LSZH), i-polyvinyl chloride (PVC), okanye i-OFNR/OFNP-zilinganiswe ngeentambo ze-flame-retardant. Ezinye izixhobo zesheath zingasetyenziswa ngokweemfuno zabathengi. Umsi ophantsi we-halogen-free polyolefin kufuneka ihlangabezane nemigangatho yeYD/T1113; i-polyvinyl chloride kufuneka ihambelane ne-GB/T8815-2008 yezinto ezithambileyo zePVC; i-thermoplastic polyurethane kufuneka ihlangabezane nemigangatho ye-YD/T3431-2018 ye-thermoplastic polyurethane elastomers.
Umsebenzi: I-sheath yangaphandle inika ukhuseleko olongezelelweyo kwimicu ye-optical, ukuqinisekisa ukuba banokuqhelana neendawo ezahlukeneyo zokufakela. Ikwabonelela ngokumelana noxinzelelo, ukucinezelwa, kunye nokugoba, ngelixa unikezela ukuxhathisa kwamanzi kunye nokufuma. Kwiimeko eziphezulu zokhuseleko lomlilo, izinto eziphantsi komsi we-halogen-free zisetyenziselwa ukuphucula ukhuseleko lwekhebula, ukukhusela abasebenzi kwiigesi ezinobungozi, umsi, kunye nomlilo xa kukho umlilo.
Sebenzisa: Umbala we-sheath kufuneka uhambelane nemigangatho ye-GB / T 6995.2. Ukuba i-fiber optical yi-B1.3-uhlobo, i-sheath kufuneka ibe tyheli; kuhlobo lwe-B6, i-sheath kufuneka ibe tyheli okanye eluhlaza; kuba AIa.1-uhlobo, kufuneka kube orenji; Udidi lwe-AIb kufuneka lube ngwevu; Uhlobo lwe-A1a.2 kufuneka lube luhlaza okwesibhakabhaka; kunye nohlobo lwe-A1a.3 kufuneka lube mfusa.
Iimeko zeSicelo
1. Ngokuqhelekileyo isetyenziswe kwiisistim zonxibelelwano lwangaphakathi ngaphakathi kwezakhiwo, ezifana neeofisi, izibhedlele, izikolo, izakhiwo zezemali, iindawo zokuthenga, amaziko edatha, njl. Ukongeza, iintambo ze-optical zangaphakathi zinokusetyenziswa kwiintambo zenethiwekhi yasekhaya, njengeeLAN kunye neenkqubo zasekhaya ezihlakaniphile.
2. Ukusetyenziswa: Iintambo ze-optical zangaphakathi zihlangene, zikhaphukhaphu, zigcina indawo, kwaye kulula ukuzifaka kunye nokuzigcina. Abasebenzisi banokukhetha iintlobo ezahlukeneyo zeentambo ze-optical zangaphakathi ezisekelwe kwiimfuno zendawo ethile.
Kumakhaya aqhelekileyo okanye iindawo zeofisi, iintambo eziqhelekileyo zePVC zangaphakathi zingasetyenziswa.
Ngokomgangatho wesizwe we-GB/T 51348-2019:
①. Izakhiwo zoluntu ezinobude obuyi-100m okanye ngaphezulu;
