Indoor optical cables anowanzo shandiswa mune yakarongeka cabling masisitimu. Nekuda kwezvinhu zvakasiyana-siyana senge nharaunda yekuvaka uye mamiriro ekuisa, dhizaini yemukati optical cables yave yakaoma. Zvishandiso zvinoshandiswa kune optical fibers uye tambo dzakasiyana, ine mechanical uye optical properties inosimbiswa zvakasiyana. Dzakajairwa indoor optical cables dzinosanganisira single-core branch cables, non-bundled cables, uye bundled cables. Nhasi, NYIKA IMWE ichatarisa pane imwe yemhando dzinozivikanwa kwazvo dzemabundled optical cables: GJFJV.
GJFJV Indoor Optical Cable
1. Kuumbwa Kwemaitiro
Iyo indasitiri-yakajairwa modhi ye indoor optical tambo ndeye GJFJV.
GJ - Kukurukurirana indoor optical cable
F - Non-metallic reinforcing chikamu
J - Tight-buffered optical fiber chimiro
V - Polyvinyl chloride (PVC) sheath
Cherechedzo: Pakupa zita rekuti, "H" inomirira hutsi husina halogen isina sheath, uye "U" inomirira polyurethane sheath.
2. Indoor Optical Cable Cross-Section Diagram
Kuumbwa Zvishandiso uye Zvimiro
1. Yakaputirwa Optical Fiber (Inoumbwa neoptical fiber uye yekunze yekupfeka layer)
Iyo optical fiber inogadzirwa ne silica zvinhu, uye yakajairwa cladding dhayamita ndeye 125 μm. Iyo dhayamita yepakati yeimwe-modhi (B1.3) ndeye 8.6-9.5 μm, uye yeakawanda-modhi (OM1 A1b) ndeye 62.5 μm. Iyo yakakosha dhayamita yeakawanda-modhi OM2 (A1a.1), OM3 (A1a.2), OM4 (A1a.3), uye OM5 (A1a.4) i50 μm.
Munguva yekudhirowa kwegirazi optical fiber, mutsetse we elastic coating inoshandiswa uchishandisa ultraviolet mwenje kudzivirira kusvibiswa neguruva. Kupfeka uku kunogadzirwa nezvinhu zvakaita se acrylate, silicone rabha, uye naironi.
Basa rekuvhara ndere kuchengetedza iyo optical fiber pamusoro kubva kune hunyoro, gasi, uye mechaniki abrasion, uye kuwedzera microbend kuita kwefiber, nekudaro kuderedza kumwe kurasikirwa kwekukotama.
Iyo yekupfeka inogona kuve neruvara panguva yekushandiswa, uye mavara anofanira kuenderana neGB/T 6995.2 (Blue, Orange, Green, Brown, Gray, White, Red, Black, Yellow, Purple, Pink, kana Cyan Green). Inogonawo kuramba isina ruvara seyakasikwa.
2. Tight Buffer Layer
Zvishandiso: Hushamwari kwezvakatipoteredza, murazvo unodzoreredza polyvinyl chloride (PVC),low utsi halogen-isina (LSZH) polyolefin, OFNR-yakatemerwa tambo inodzoreredza moto, OFNP-yakatemerwa tambo inodzoreredza moto.
Basa: Iyo inowedzera kuchengetedza iyo optical fibers, ichivimbisa kuchinjika kwavo kune akasiyana ekuisa mamiriro. Inopa kuramba kune tension, compression, uye kukotama, uye zvakare inopa mvura nekunyorova kuramba.
Shandisa: Iyo yakasimba buffer layer inogona kuve neruvara-coded kuti izivikanwe, ine mavara macode anoenderana neGB/T 6995.2 zviyero. Kuti zvizivikanwe zvisina mwero, mhete dzemavara kana madotsi anogona kushandiswa.
3. Kusimbisa Zvikamu
Material:Aramid yarn, kunyanya poly(p-phenylene terephthalamide), rudzi rutsva rwepamusoro-tech synthetic fiber. Iyo ine zvinhu zvakanakisa senge Ultra-yakakwirira simba, yakakwirira modulus, yakakwirira tembiricha kuramba, asidhi uye alkali kuramba, huremu, insulation, kuramba kuchembera, uye hupenyu hurefu hwebasa. Pakupisa kwepamusoro, inochengetedza kugadzikana, ine yakaderera shrinkage mwero, kushoma kunokambaira, uye yakakwirira yegirazi tembiricha yekuchinja. Iyo zvakare inopa yakakwira corrosion kuramba uye isiri-conductivity, ichiita iyo yakanakira yekusimbisa zvinhu kune optical tambo.
Basa: Aramid shinda yakatenderedzwa yakatenderedzwa kana kuiswa kureba mune tambo sheath kuti ipe tsigiro, inosimudzira tambo yekusimba uye kumanikidza kuramba, simba remuchina, kugadzikana kwemafuta, uye kugadzikana kwemakemikari.
Aya maitiro anovimbisa kutapurirana kwetambo uye hupenyu hwesevhisi. Aramid inowanzo shandiswawo mukugadzirwa kwemabhuruku nemaparachuti nekuda kwesimba rayo rakanaka.
4. Outer Sheath
Zvishandiso: Utsi hwepasi halogen-isina murazvo-retardant polyolefin (LSZH), polyvinyl chloride (PVC), kana OFNR/OFNP-yakatemerwa tambo dzinodzora moto. Zvimwe zvinhu zve sheath zvinogona kushandiswa sezvinodiwa nevatengi. Yakaderera utsi halogen-isina polyolefin inofanira kusangana neYD/T1113 zviyero; polyvinyl chloride inofanira kuenderana neGB/T8815-2008 yezvinhu zvinyoro zvePVC; thermoplastic polyurethane inofanira kusangana neYD/T3431-2018 zviyero zve thermoplastic polyurethane elastomers.
Basa: Iyo yekunze sheath inopa yakawedzera dziviriro kune iyo optical fibers, kuve nechokwadi kuti vanogona kuchinjika kune akasiyana ekuisa nharaunda. Inopawo kuramba kune tension, compression, uye kukotama, uku ichipa mvura uye hunyoro kuramba. Nokuda kwezviitiko zvekuchengetedza moto zvakanyanya, hutsi hushoma husina halogen hunoshandiswa kuvandudza kuchengetedzwa kwetambo, kudzivirira vashandi kubva kumagasi anokuvadza, utsi, uye moto kana moto.
Shandisa: Iyo sheath color inofanirwa kuenderana neGB/T 6995.2 zviyero. Kana iyo optical fiber iri B1.3-mhando, sheath inofanira kuva yero; yeB6-mhando, sheath inofanira kuva yero kana yakasvibirira; yeAIa.1-mhando, inofanira kuva orenji; AIb-mhando inofanira kuva grey; A1a.2-mhando inofanira kuva cyan girini; uye A1a.3-mhando inofanira kuva yepepuru.
Application Scenarios
1. Inowanzoshandiswa mumagadzirirwo ekukurukurirana kwemukati mukati mezvivako, zvakadai semahofisi, zvipatara, zvikoro, zvivako zvemari, zvivako zvekutengesa, nzvimbo dzepa data, etc. Inonyanya kushandiswa pakubatana pakati pemichina mumakamuri evhavha uye kushamwaridzana kwekukurukurirana nevanoshanda kunze. Pamusoro pezvo, tambo dzemukati dzemaziso dzinogona kushandiswa mudzimba network wiring, senge maLAN uye smart home system.
2. Kushandisa: Indoor optical cables dzakasimba, dzakareruka, dzinochengetedza nzvimbo, uye dziri nyore kuisa nekuchengetedza. Vashandisi vanogona kusarudza mhando dzakasiyana dzemukati optical tambo zvichienderana nezvinodiwa nharaunda.
Mudzimba dzakajairwa kana nzvimbo dzehofisi, tambo dzemukati dzePVC dzinogona kushandiswa.
Zvinoenderana neiyo yenyika standard GB/T 51348-2019:
①. Zvivakwa zveveruzhinji zvine hurefu hwe100m kana kupfuura;
②. Zvivakwa zveveruzhinji zvine hurefu huri pakati pe50m ne100m uye nzvimbo inopfuura 100,000㎡;
③. Data nzvimbo dzeB giredhi kana pamusoro;
Idzi dzinofanira kushandisa tambo dzemaziso dzisingadzoreki nemoto dzine mwero wemoto usingadzikire pane wakaderera-utsi, halogen-isina B1 giredhi.
Mune UL1651 yakajairwa muUS, mhando yepamusoro-soro-inodzosa tambo yetambo ndeye OFNP-yakatemerwa optical tambo, iyo yakagadzirirwa kuzvidzima mukati memamita mashanu kana yaiswa mumurazvo. Pamusoro pezvo, haiburitse chiutsi chine muchetura kana mhute, ichiita kuti ive yakakodzera kuisirwa mumataipi ekufemesa kana mhepo-yekudzoreredza masisitimu anoshandiswa mumidziyo yeHVAC.
