Ndedzipi nzira dzekubatanidza fiber?
1. Active connection:
Active connection inzira yekubatanidza saiti kune saiti kana saiti kune tambo yefiber optic uchishandisa akasiyana siyana fiber optic yekubatanidza michina (mapulagi nezvigadziko).Iyi nzira inoshanduka, yakapusa, yakanakira, uye yakavimbika, uye inowanzoshandiswa mumakombuta network wiring muzvivakwa.Yayo yakajairika attenuation ndeye 1dB / chinongedzo.
2. Emergency connection (inozivikanwawo se) kunyungudika kunotonhora:
Emergency yekubatanidza inonyanya kushandisa michina nemakemikari nzira kugadzirisa uye kubatanidza maviri optical fibers pamwechete.Hunhu hukuru hweiyi nzira ndeyekuti kubatana kunokurumidza uye kwakavimbika, uye yakajairika attenuation yekubatanidza ndeye 0.1-0.3dB / point.
Iwo anogona kubatirwa mumakonikisheni uye akaroverwa mumasokisi efiber optic.Iyo yekubatanidza inoshandisa 10% kusvika 20% yechiedza, asi inoita kuti zvive nyore kugadzirisa zvakare hurongwa.Zvisinei, nzvimbo yekubatanidza ichave isina kugadzikana kwenguva yakareba uye kuderedzwa kuchawedzera zvakanyanya, saka inogona kungoshandiswa pakukurumidzira mukati. nguva pfupi.
Inogona kubatanidzwa nemichina.Kuti uite izvi, isa imwe mugumo wemafiibhi maviri akanyatsochekwa muchubhu woasunga pamwechete.Iyo fiber inogona kugadziriswa kuburikidza nejunction kuti iwedzere chiratidzo.Mechanical bonding inoda anenge maminetsi mashanu kuti vashandi vakadzidziswa vapedze, uye kurasikirwa kwechiedza kunenge 10%.
3. Permanent fiber connection (inozivikanwawo sehot melt):
Mhando iyi yekubatanidza inoshandisa kubuda kwemagetsi kusanganisa uye kubatanidza nzvimbo dzekubatanidza dzefiber.Inowanzo shandiswa kubatanidza kureba-kure, zvachose kana semi-chisingaperi yakagadziriswa yekubatanidza.Chinhu chayo chikuru ndechekuti iyo yekubatanidza attenuation ndiyo yakaderera pakati pese nzira dzekubatanidza, ine yakajairika kukosha kwe0.01-0.03dB / poindi.
Nekudaro, kana uchibatanidza, yakakosha michina (welding muchina) uye mashandiro ehunyanzvi anodiwa, uye nzvimbo yekubatanidza inoda kuchengetedzwa nemudziyo unokosha.Idzo shinda mbiri dzinogona kubatanidzwa pamwechete kuti dzigadzire kubatana kwakasimba.
Iyo fiber inoumbwa neiyo fusion nzira yakada kufanana nefiber imwe chete, asi pane zvishoma attenuation.Kune ese matatu nzira dzekubatanidza, pane ratidziro pajunction, uye simba rinoratidzwa rinopindirana nechiratidzo.
Izvo zvinodikanwa kuti unzwisise kurasikirwa kweiyo optical fiber kuitira kuti ushandise zviri nani iyo optical fiber.Basa guru reFluke's CertiFiber Pro Optical Loss Test fiber kurasikirwa tester ndeyekuyedza kurasikirwa uye kutadza chikonzero chefiber.
Fluke's CertiFiber Pro Optical Loss Test Fiber kurasikirwa tester inogona:
1. Matatu-sekondi otomatiki bvunzo - (kakapetwa kane nekukurumidza kupfuura echinyakare testers) inosanganisira: yekuona kurasikirwa kuyerwa pamafiber maviri ewavelengths maviri, kuyerwa kwechinhambwe uye kurasika kwebhajeti kuverenga.
2. Ipa otomatiki kupasa / kukundikana kuongororwa kunoenderana neindasitiri zviyero kana tsika yekuyera miganhu
3. Ziva maitiro asina kururama ekuedzwa anokonzera "kurasikirwa kusina kunaka" migumisiro
4.Onboard (USB) yekuongorora kamera inonyora fibre endface image
.
6.Built-in video fault locator for basic diagnostics uye polarity kuonekwa
7. Dual wavelength kuyerwa kugona pane imwe fiber inobvumira muyedzi kuti ashandiswe mumaapplication anoda imwe chete fiber link.
Hapana mimwe michina kana maitirwo anodiwa kutevedzera TIA-526-14-B uye IEC 61280-4-1 ring flux zvinodiwa.
Ndeupi musiyano uripo pakati pe optical tambo uye optical fiber
Iyo optical cable inoumbwa neimwe nhamba ye optical fibers.Iyo yekunze core yakafukidzwa nesheath uye inodzivirira layer yekutaurirana uye kure-kure-kure-kugona kufambisa ruzivo.
Optical fiber chishandiso chekufambisa, kungofanana newaya yakatetepa yepurasitiki.Yakanyanya kutetepa optical fiber inozovharirwa mune repurasitiki sleeve kuitira kureba ruzivo rwekufambisa.Saka iyo fiber optic tambo ine optical fiber.
Pakupedzisira, ngatitaure nezvetambo.Tambo inoumbwa neye conductive wire core, insulation layer, uye chisimbiso chekudzivirira layer.Inogadzirwa nesimbi (kazhinji mhangura, aluminium) sekondakita, uye inoshandiswa kufambisa simba kana ruzivo.Waya dzakamonyoroka.Cables anonyanya kushandiswa mukutakura hubs, substations, etc. Kutaura zvazviri, waya netambo hazvina miganhu yakasimba.Kazhinji, tinodaidza waya dzine madhayamita madiki uye maseru mashoma sewaya, uye tambo dzine madhayamita makuru uye masero mazhinji.
Zvinoita here kuti optical fibers idzore zvachose tambo dzemhangura kubva kunze?
Munzvimbo zhinji dzedata, fiber yakatonga pamusika nekuda kwepamusoro bandwidth zvinodiwa.Pamusoro pezvo, tambo dzefiber optic hadzisi pasi pekukanganiswa kwemagetsi, uye yavo yekuisa nharaunda zvinodiwa hazvina kuoma setambo dzemhangura.Naizvozvo, iyo optical fiber iri nyore kuisa.
Nekudaro, zvinofanirwa kucherechedzwa kuti kunyangwe mutengo wepakati pakati peoptical fibers uye tambo dzemhangura dzakaderera, mutengo wakazara wetambo dzemagetsi wakakwira kupfuura tambo dzemhangura.Naizvozvo, fiber inoshandiswa zvakanyanya munzvimbo dzinoda bandwidth yakakwirira, senge data data.
Ukuwo, tambo dzemhangura dzinodhura zvishoma.Optical fiber imhando yakakosha yegirazi faibha iyo isina kusimba kupfuura tambo dzemhangura.Nokudaro, mari yekuchengetedza zuva nezuva yetambo yemhangura yakaderera zvikuru kupfuura ye optical fiber.Inopawo kumashure kuenderana neyekare gumi / 100Mbps legacy Ethernet zvishandiso.
Naizvozvo, tambo dzemhangura dzichiri kushandiswa mukufambisa kwezwi uye indoor network application.Mukuwedzera, horizontal cabling, Simba pamusoro peEthernet (POE), kana Indaneti yezvinhu zvikumbiro zviri kutyaira kushandiswa kwetambo dzemhangura.Naizvozvo, tambo dzefiber optic hadzizotsiva zvachose tambo dzemhangura.
Nezve ruzivo rudiki rwe optical fiber, ini ndichasundira pano kune wese munhu nhasi.Fiber optic cables uye tambo dzemhangura dzinogona kupa chaizvo Internet yekubatanidza masevhisi edzimba nemabhizinesi.Muchokwadi, optical fiber uye mhangura mhinduro dzichagara mune ramangwana rinoonekwa, uye imwe neimwe mhinduro ichashandiswa painonzwisisika.
