Fiber Optic Cable (FOC) chikamu chakakosha chemazuva ano ekutaurirana network, uye inobata chinzvimbo chakakosha mumunda wekufambiswa kwedata nehunhu hwayo hwekumhanya kwakanyanya, bandwidth yakakwira uye kugona kwakasimba kunopesana nekukanganisa. Ichi chinyorwa chichasuma chimiro chefiber optic tambo zvakadzama kuitira kuti vaverengi vanzwisise zvakadzama nezvazvo.
1. Basic kuumbwa kwefiber-optic cable
Fiber optic cable inonyanya kuumbwa nezvikamu zvitatu: fiber optic core, cladding uye sheath.
Fiber optic core: Uyu ndiwo musimboti wefiber optic tambo uye ine basa rekutumira masaini masaini. Fiber optic cores inowanzo gadzirwa negirazi rakachenesesa kana epurasitiki, ine dhayamita yemamicrons mashoma. Dhizaini yepakati inovimbisa kuti iyo optical chiratidzo inofamba nayo nemazvo uye nekurasikirwa kwakanyanya.
Cladding: Yakavharidzirwa kumativi epakati pefiber ndiyo cladding, iyo refractive index yakaderera zvishoma pane iyo yepakati, uye iyo yakagadzirirwa kubvumira chiratidzo chemaziso kuti chiendeswe mukati mepakati nenzira inonyatsoratidza, nokudaro kuderedza kurasikirwa kwechiratidzo. Iyo yekuvharisa inogadzirwawo negirazi kana epurasitiki uye inodzivirira pamuviri musimboti.
Jacket: Iyo jekete rekunze rakagadzirwa nechinhu chakaomarara senge polyethylene (PE) kana polyvinyl chloride (PVC), iyo basa guru nderokudzivirira iyo fiber optic core uye cladding kubva mukukanganisa kwezvakatipoteredza senge abrasion, unyoro uye kemikari corrosion.
2. Mhando dzefiber-optic cables
Zvinoenderana nekurongeka uye kudzivirira kweiyo optical fibers, fiber optic tambo dzinogona kukamurwa kuita anotevera marudzi:
Laminated stranded fiber optic cable: chimiro ichi chakafanana netambo dzechinyakare, umo akawanda optical fibers akasungirirwa akapoteredza chepakati reinforcing core, achigadzira chitarisiko chakafanana neicho chekirasi tambo. Laminated stranded faibha optic tambo dzine yakakwirira tensile simba uye zvakanaka kukotama zvinhu, uye vane dhayamita duku, zvichiita kuti zvive nyore nzira uye kuchengetedza.
Skeleton cable: Iyi tambo inoshandisa skeleton yepurasitiki sechimiro chekutsigira che optical fiber, iyo optical fiber inogadziriswa mumigero ye skeleton, iyo ine maitiro akanaka ekudzivirira uye kugadzikana kwemaitiro.
Center bundle chubhu tambo: iyo optical fiber inoiswa pakati pe optical cable tube, yakakomberedzwa nesimbi inosimbisa uye kuchengetedzwa kwejasi, chimiro ichi chinobatsira kuchengetedzwa kwemashizha emagetsi kubva kunze kwekunze.
Ribhoni tambo: iyo optical fibers yakarongwa muchimiro chemarabhoni ane spacing pakati pega yega fiber ribhoni, dhizaini iyi inobatsira kuvandudza simba rekusimba uye lateral compression kuramba kwetambo.
3. Zvimwe zvikamu zvefiber-optic cables
Pamusoro peiyo basic optical fibres, cladding uye sheath, fiber optic tambo dzinogona kunge dziine zvinotevera zvimwe zvikamu:
Reinforcement core: Iri pakati peiyo fiber optic tambo, inopa yakawedzera mechani simba kurwisa masimba ekumanikidza uye kushushikana.
Buffer layer: Iri pakati pe fiber uye sheath, inowedzera kuchengetedza fiber kubva pakukanganisa uye abrasion.
Armouring layer: Dzimwe tambo dzefiber optic dzinewo imwe yekuwedzera yekudzivirira, senge simbi tepi nhumbi dzokurwa, kuti dzipe imwe dziviriro kune dzakaoma nharaunda kana panodiwa kuchengetedzwa kwemagetsi.
4. Maitiro ekugadzira matambo efibre-optic
Kugadzirwa kwefiber optic cablesinosanganisira yakakwirira chaiyo maitiro, anosanganisira matanho akadai sekudhirowa kwefiber optics, coating of cladding, stranding, tambo kugadzira uye sheath extrusion. Nhanho imwe neimwe inoda kunyatsodzorwa kuti ive nechokwadi chekuita uye kunaka kweiyo fiber optic tambo.
Muchidimbu, dhizaini yekugadzira tambo dze optical fiber inofunga nezvese kufambiswa kwakanaka kwezviratidzo zvemaziso uye kuchengetedzwa kwemuviri uye kuchinjika kwezvakatipoteredza. Nekuenderera mberi kwekufambira mberi kwetekinoroji, chimiro uye zvinhu zvefiber optic cables zviri kuvandudzwa kuti zvizadzise kudiwa kuri kukura kwekutaurirana.
