Fiber optic cable kuvaka yakakamurwa kuita zvinotevera matanho: kugadzirira → chirongwa chekufambisa → kuiswa kwefiber optic cable → fiber optic cable splicing → kugamuchirwa kweprojekiti.
1. Kugadzirira
(1) tarisa ruzivo rwekugadzira, mbishi zvinhu, midziyo yekuvaka, uye midziyo yakakwana.
(2) gadza chikwata chekuvaka chemhando yepamusoro. Izvi zvakakosha nekuti kuvakwa kwefiber optic pane zvinodiwa zvekuvaka tambo zvakanyanya kuomarara. Chero kusave nehanya mukuvaka kungangokonzera kuwedzera kwefiber kurasikirwa kana kunyange kutsemuka musimboti.
2. Routing engineering
(1) pamberi kuisa tambo yefiber optic inofanira kutanga yaita ongororo yakakomba yenzira kuburikidza netambo yefiber optic. Nzwisisa kugadzirwa kwemigwagwa yemuno uye kuronga, edza kunzvenga madziva, minda yegorosi, zviteshi zvepeturu, nezvimwe zvakadaro zvinogona kuvanzwa njodzi. Mushure menzira yakatemwa, kuyerwa chaiko kwekureba kwayo kunoitwa, yakarurama kusvika mukati me50m. Zvakare, wedzera kukotama kwechisikigo uye kureba kwakasiyana kwakachengetwa panguva yekuendesa. Kuchengetedzwa kwakasiyana-siyana kunosanganisirawo kuiswa kwekukotama mugomba, kuchengetedza padanda, kuchengetedza kumativi ose maviri ejoini, uye kumwe kuchengetedzwa kwakakosha sekuwedzera kukombama kwendege yakachinjika. Kuti ugadzire tambo yefiber optic pakaitika kutyora uye wobva wabatanidza, inofanira kusiiwa pamamita zana ega ega neimwe muganho, kureba kwemuganho kazhinji 5% kuti 10%. Ronga zvinoenderana nehurefu chaihwo hunodiwa uye tsanangura paunenge uchipepeta tireyi.
(2) Dhirowa mifananidzo yekugadzira nzira. Kuverengera pamatanda asati adyarwa, dhirowa dhayagiramu yekugadzira nzira uye taura nhamba yedanda rega rega kana yepasi pevhu pombi yekubuda nayo uye kureba kwepombi. Isa hurefu uye nzvimbo yezvinodiwa zvekusiya muganho. Izvi zvinogona kunyatsoshandisa kureba kwefiber optic cable, gadziriro inonzwisisika kuitira kuti fusion splice point ideredzwe.
(3) Majoini maviri efiber optic anoiswa zvakanaka mufurati, geologically yakagadzikana nzvimbo. Dzivisa madziva, nzizi, migero, nemigwagwa, zvichida iri panobuda danda kana pombi. Pamusoro pefiber optic cable joints dzinofanira kuwira padivi pedanda 0.5 ~ 1m kana zvakadaro, basa iri rinozivikanwa se “ndiro yekugovera”. Iyo inonzwisisika yekugovera ndiro inogona kuderedza fusion point. Pamusoro pe, mifananidzo yekuvaka inofanirawo kuratidza nzvimbo yefusion point, apo iyo fiber optic cable breakpoint, zviri nyore kukurumidza kushandisa chiridzwa kuti uwane iyo breakpoint yekugadzirisa.
3 fiber optic cable kuisa
(1) iyo imwechete batch ye optical fiber, dhayamita yayo yemumunda ndiyo yakafanana, iyo fiber pane imwe nzvimbo yekudimbura, pakati pemigumo miviri yendima yemodhi, zvinogona kuonekwa zvakafanana. Saka, fusion splicing mune ino disconnect poindi inogona kuita iyo mode yemunda dhayamita yefiber fusion kurasikirwa kusvika kushoma. Saka zvinoda mugadziri wetambo ane batch imwechete ye bare fiber, maererano nezvinodiwa zvehurefu hwetambo hunoramba huchigadzirwa, mutireyi yega yega pakutevedzana kwenhamba, uye zvakanyorwa A (tsvuku), B (girinhi) end, hapana jump number. Erection ye fiber optic tambo dzinoda kuiswa padivi peyakatemerwa nzira yekutevedzana zvichienderana nenhamba uye kuve nechokwadi chekuti B kuguma kweyapfuura tray yefiber optic tambo yakabatana neA kupera kwetirayi inotevera yefiber optic tambo.. Kuve nechokwadi chekuti kupatsanurwa kwemadhayamita maviri emunda wefiber kunenge kwakafanana kuitira kuti kukosha kwekurasikirwa kwefusion kuwane hushoma..
(2) pamusoro fiber optic tambo inogona kushandiswa 72.2mm galvanized steel stranded waya yekurembera tambo kuturika. Waya inorembera uye tambo yefiber optic kuti inyatsodzika pasi, kuva nemheni, zviyero zvemagetsi, nokudengenyeka kwenyika, mhepo mechanical properties. Pamusoro wakarembera waya uye tambo yemagetsi yakachinjika uye yakatwasuka kureba kusvika kupfuura 2m, kubva pasi kusvika paurefu hushoma hwe5m, kubva padenga kusvika padiki chinhambwe che 1.5m. Pamusoro faibha optic tambo yekurembera mhando kune marudzi matatu: kurembera waya yakarembera bracket kurembera mhando, yakarembera waya inomonereka mhando, uye kuzvitsigira mhando. Kuzvitsigira mhando isina simbi yakasungwa yakaturika waya, cable sagging, mhepo yakaipa mutoro, saka inowanzoshandiswa yakaturika mhando.
(3) pamusoro pepamusoro fiber optic cable kuiswa. Nekuda kwehurefu hwereel kupfuura tambo, kureba kunogona kusvika makiromita akati wandei, inoganhurirwa neiyo inobvumidzwa yakatemerwa tension uye bending radius, kunyanya kukoshesa mukuvaka hakugoni kudhonzwa uye kuitika kwekink phenomenon. General fiber optic tambo inogona kubvumidzwa kudhonza pamusoro 150 ~ 200kg. Iyo tambo yekubhenda radius inofanirwa kuve yakakura kupfuura kana kuenzana nayo 10 ~ 15 nguva kunze dhayamita yetambo, uye kuvakwa kweradius yekubhenda kunofanira kuva yakakura kudarika kana kuenzana 20 nguva dzekutumirwa. Kuitira kudzivirira tambo yefiber optic yakaiswa pakati pemugwagwa, anenge 20m kubva padanda, inomiswa mumativi maviri akapesana, hafu yekutanga vhoriyamu, muhafu yechipiri vhoriyamu yefiber optic tambo kubva mundiro zvichidzika. Maererano ne “8” mhando nzira pasi, uyezve kutumirwa.
(4) mukuisa tambo, rambidza tambo kutamba denderedzwa diki uye peta, twist, uye kuve akashongedzerwa neimwe nhamba yemaintercom. The the “famba mberi uchiteverwa netambo pabendekete” nzira yekuisa tambo, inogona kudzivirira zvinobudirira kuitika kwebhagi rekumashure. Zvakare, teerera kune simba rakafanana, simba rekudhonza haripfuuri 80% yetambo inobvumirwa, uye iyo yakanyanya instantaneous traction simba haipfuure 100%. Pamusoro pe, pakumisa, mukubhenda kwetambo kana nzvimbo yakaomarara inofanirwa kuve nemhosva yemotokari inorambidzwa zvachose kupwanya.. Kuendesa pamusoro pefiber optic tambo uchishandisa pulley mota, pre-yakaturika pulleys padanda romutanda uye kurembera mutsara (kazhinji zvese 10 ~ 20m kurembera pulley), mufiber optic tambo inoenda kumusoro kune pulley, inotungamira pasi kune pulley kuderedza drape, kuderedza kushushikana. Zvadaro pfeka tambo yakanaka yekukwevera pakati pemapulleys, tambo yekukweva yakasungirirwa kumusoro wetambo, neimwe tsigiro kuti tambo ikwire padanda rerekeni, kurembera pamutsetse wokurembera. Fiber optic cable hook spacing ye40cm, hoko munzira yehitch pamutsetse wehanger kuti uenderane. Danda rega rega rinofanirwa kunge riine gutter yeconvex, uye tireyi yega yega yefiber optic cable inofanira kusiiwa pajoinhi ine danda rehurefu pamwe ne3m yekumucheto. Kuti iyo splice bhokisi pasi fusion kushanda, uye mazana mashoma emamita ega ega kuve neimwe ndiro inogara.
4. Fiber optic cable splicing
Common fiber optic tambo dzine laminated, skeleton, uye pakati bundle chubhu faibha optic tambo. Ruvara rwepakati rwakakamurwa mune iyi hurongwa, orenji, girinhi, bhurawuni, gireyi, chena, nhema, tsvuku, yero, pepuru, pink, uye green green, iyo inonzi iyo yakazara-ruvara spectrum yepakati. Vamwe vanogadzira tambo dzefiber optic vanoshandisa “bhuruu” kutsiva ruvara muruvara rwemavara. Multicore fiber optic tambo kune akasiyana mavara efiber mune imwechete bundle yemachubhu kuita boka, saka multicore fiber optic tambo inogona kunge iine akati wandei. Muchinjikwa-chikamu chefiber optic tambo, iyo red bundle chubhu seyekutanga bundle refiber optic tambo, clockwise kune chena, machena maviri, machena matatu …… yekupedzisira ndeye green bundle chubhu. Mu fiber optic splicing, musimboti unofanira kuteverwa: nhamba yemacores yakaenzana. Mune imwechete bundle yeinoenderana ruvara fiber butt, nhamba yemacores yakasiyana panguva imwe chete, kuitira kuti utange wabatanidza musimboti wehombe, ipapo musimboti wediki.
Zviri pamusoro apa “nzira yekumisa fiber optic tambo?” Ndinovimba inogona kukubatsira.
