Tambo dzemagetsi dzemukati dzinoshandiswa zvakanyanya mumasisitimu emagetsi akagadzirwa. Nekuda kwezvinhu zvakasiyana-siyana zvakaita senzvimbo yekuvaka nemamiriro ekuisa, dhizaini yetambo dzemagetsi dzemukati dzave dzakaoma. Zvinhu zvinoshandiswa pakugadzira mafiber emagetsi netambo dzakasiyana-siyana, uye hunhu hwemakanika nehwemagetsi hunosimbiswa zvakasiyana. Tambo dzemagetsi dzemukati dzinoshandiswa dzinosanganisira tambo dzebazi rimwe chete, tambo dzisina kuunganidzwa, uye tambo dzakaunganidzwa. Nhasi, ONE WORLD ichatarisa pane imwe yemhando dzakajairika dzetambo dzemagetsi dzakaunganidzwa: GJFJV.
GJFJV Tambo yeOptical yemukati
1. Kuumbwa kweZvivako
Muenzaniso wemagetsi emukati meimba unoshandiswa zvakanyanya muindasitiri iyi ndiGJFJV.
GJ — Tambo yekutaurirana yemukati memagetsi
F — Chinhu chisiri chesimbi chinosimbisa
J — Chimiro chefiber ye optical chakasimba
V — Mudziyo wePolyvinyl chloride (PVC)
Cherechedza: Pakutumidza zvinhu zvemushedhi, "H" inomiririra shedhi isina hutsi hwakanyanya, uye "U" inomiririra shedhi yepolyurethane.
2. Dhizaini yeMutambo weOptical Cable Cross-Section
Zvinhu Zvinoumba uye Zvimiro
1. Fiber yeOptical Yakaputirwa (Yakaumbwa nefiber ye optical uye jira rekunze rekuputira)
Fiber ye optical yakagadzirwa ne silica material, uye dhayamita ye cladding yakajairwa i 125 μm. Dhayamita yepakati ye single-mode (B1.3) i 8.6-9.5 μm, uye ye multi-mode (OM1 A1b) i 62.5 μm. Dhayamita yepakati ye multi-mode OM2 (A1a.1), OM3 (A1a.2), OM4 (A1a.3), uye OM5 (A1a.4) i 50 μm.
Panguva yekudhirowa kwegirazi re optical fiber, jira re elastic coating rinoiswa uchishandisa ultraviolet light kudzivirira kusvibiswa neguruva. Pendi iyi yakagadzirwa nezvinhu zvakaita se acrylate, silicone rabha, uye nylon.
Basa rekuvhara nderekudzivirira pamusoro pefiber ye optical kubva kuhunyoro, gasi, uye kukweshwa kwemuchina, uye kuwedzera mashandiro e microbend yefiber, nokudaro zvichideredza kurasikirwa kwakawedzerwa kwekukotama.
Pendi yacho inogona kupendwa panguva yekushandiswa, uye mavara acho anofanira kuenderana neGB/T 6995.2 (Bhuruu, Orenji, Girini, Bhurawuni, Gireyi, Chena, Tsvuku, Dema, Yero, Purple, Pink, kana Cyan Green). Inogonawo kuramba isina ruvara seyakasikwa.
2. Chigadziko cheBuffer chakasimba
Zvinhu: Inochengetedza zvakatipoteredza, polyvinyl chloride (PVC) inodzivirira moto,polyolefin isina utsi hwakanyanya (LSZH), tambo inodzivirira moto ine chiyero cheOFNR, tambo inodzivirira moto ine chiyero cheOFNP.
Basa: Inodzivirirawo mafiber e optical, ichiva nechokwadi chekuti anochinjika mumamiriro akasiyana-siyana ekuisa. Inodzivirira kumanikidzwa, kumanikidzwa, uye kukotama, uye inopawo kudzivirira mvura nehunyoro.
Mashandisirwo: Chikamu chakasimba chebuffer chinogona kunyorwa mavara kuti chizivikanwe, nemakodhi emavara achienderana nezvinodiwa zveGB/T 6995.2. Pakuzivikanwa kusiri kwakajairika, mhete dzemavara kana madotsi zvinogona kushandiswa.
3. Zvikamu Zvinosimbisa
Zvinyorwa:shinda yeAramid, kunyanya poly(p-phenylene terephthalamide), rudzi rutsva rwefiber yekugadzira yakagadzirwa netekinoroji yepamusoro. Ine hunhu hwakanaka hwakadai sesimba rakakwirira kwazvo, modulus yakakwira, kuramba kupisa kwakanyanya, kuramba acid nealkali, kureruka, kudzivirira kupisa, kuramba kukwegura, uye kugara kwenguva refu. Pakupisa kwakanyanya, inochengetedza kugadzikana, ine mwero wakaderera wekudonha, kukambaira kushoma, uye kupisa kwakanyanya kwekuchinja kwegirazi. Inopawo kuramba ngura kwakanyanya uye kusafambisa mafambiro emhepo, zvichiita kuti ive chinhu chakakodzera chekusimbisa tambo dze optical.
Basa: Uta hweAramid hwakatenderedzwa zvakaenzana kana kuiswa muchikamu chetambo kuti hutsigire, zvichiwedzera kusimba kwetambo, simba remuchina, kugadzikana kwekupisa, uye kugadzikana kwemakemikari.
Hunhu uhwu hunovimbisa kushanda kwetambo uye hupenyu hwebasa rayo. Aramid inowanzoshandiswawo mukugadzira mavesti asingapindi mabara uye maparachuti nekuda kwesimba rayo rakanaka rekudhonza.
4. Mugoba weKunze
Zvinhu: Tambo dze polyolefin (LSZH) dzisina utsi hushoma, polyvinyl chloride (PVC), kana tambo dze OFNR/OFNP dzinodzora moto. Zvimwe zvinhu zve sheath zvinogona kushandiswa zvichienderana nezvinodiwa nevatengi. Polyolefin isina utsi hushoma inofanira kusangana neYD/T1113 standards; polyvinyl chloride inofanira kutevedzera GB/T8815-2008 yezvinhu zvakapfava zvePVC; thermoplastic polyurethane inofanira kusangana neYD/T3431-2018 standards dze thermoplastic polyurethane elastomers.
Basa: Chivharo chekunze chinopa dziviriro yakawedzerwa kumafiber e optical, zvichiita kuti akwanise kuchinjika munzvimbo dzakasiyana-siyana dzekuisa. Chinopawo dziviriro yekumanikidzwa, kumanikidzwa, uye kukotama, ukuwo chichipa dziviriro yemvura nehunyoro. Pamamiriro ekudzivirira moto zvakanyanya, zvinhu zvisina hutsi hushoma zvinoshandiswa kuvandudza kuchengetedzeka kwetambo, kudzivirira vashandi kubva kumagasi anokuvadza, utsi, uye marimi emoto kana moto ukabvira.
Mashandisirwo: Ruvara rweganda runofanira kuenderana nezvinodiwa neGB/T 6995.2. Kana fiber ye optical iri yerudzi rweB1.3, ganda rinofanira kunge riri yero; kune yerudzi rweB6, ganda rinofanira kunge riri yero kana girini; kune yerudzi rweAIa.1, rinofanira kunge riri orenji; AIb-type inofanira kunge iri grey; A1a.2-type inofanira kunge iri cyan green; uye A1a.3-type inofanira kunge iri yepepuru.
Maitiro Ekushandisa
1. Inoshandiswa zvakanyanya mumasisitimu ekutaurirana mukati mezvivakwa, zvakaita semahofisi, zvipatara, zvikoro, zvivakwa zvemari, nzvimbo dzekutenga, nzvimbo dzedata, nezvimwewo. Inonyanya kushandiswa pakubatanidza michina iri mumakamuri eseva uye kubatana kwekutaurirana nevanoshanda kunze. Pamusoro pezvo, tambo dzemukati dze optical dzinogona kushandiswa mukubatanidza waya dzenetwork dzepamba, dzakadai seLANs uye masisitimu edzimba dzakangwara.
2. Mashandisirwo: Tambo dzemagetsi dzemukati dzakatetepa, dzakareruka, dzinochengetedza nzvimbo, uye dziri nyore kuisa nekugadzirisa. Vashandisi vanogona kusarudza mhando dzakasiyana dzetambo dzemagetsi dzemukati zvichienderana nezvinodiwa nenzvimbo chaiyo.
Mudzimba dzakajairika kana munzvimbo dzemahofisi, tambo dzePVC dzemukati dzinogona kushandiswa.
Zvichienderana nechiyero chenyika cheGB/T 51348-2019:
①. Zvivako zveveruzhinji zvine urefu hwemamita zana kana kupfuura;
②. Zvivako zveveruzhinji zvine urefu huri pakati pemamita makumi mashanu nemakumi mashanu (50m) negumi (100m) nenzvimbo inodarika 100,000㎡;
③. Nzvimbo dzedata dzegiredhi B kana kupfuura;
Idzi dzinofanira kushandisa tambo dzemagetsi dzinodzivirira moto dzine chiyero chemoto chisingasviki giredhi reB1 risingapfuure utsi hwakaderera, risina halogen.
Mumutemo weUL1651 muUS, tambo yemhando yepamusoro inodzivirira moto ndeye tambo ye OFNP-rated optical, iyo yakagadzirirwa kuzvidzima yoga mukati memamita mashanu kana yaiswa mumoto. Pamusoro pezvo, haiburitse utsi kana mhute ine chepfu, zvichiita kuti ikodzere kuiswa mumapayipi emhepo kana masisitimu ekumanikidza mweya anoshandiswa mumidziyo yeHVAC.
