Mumakore mashoma apfuura, fiber optic tambo yave kutengeka zvakanyanya.Iko zvino yave kushandiswa kune akawanda ezvishandiso zvinoda kusadzivirirwa kuzere kukanganiswa kwemagetsi.Fiber yakanakira yakakwira data-reti masisitimu akadai seFDDI, multimedia, ATM, kana chero imwe network inoda kutamiswa kwemafaira makuru, anopedza nguva.
Zvimwe zvakanakira fiber optic tambo pamusoro pemhangura zvinosanganisira:
• Chinhambwe chikuru-Unogona kumhanya faibha kusvika makiromita akati wandei.• Low attenuation-Zviratidzo zvemwenje zvinosangana kushoma kushoma, saka data inogona kufamba kure.
• Chengetedzo-Matepi mufiber optic tambo iri nyore kuona.Kana ikabatwa, tambo inodonhedza mwenje, zvichiita kuti sisitimu yese ikundikane.
• Yakakura bandwidth-Fiber inogona kutakura data yakawanda kupfuura mhangura.• Immunity-Fiber optics haigoni kukanganiswa.
Single-mode kana multimode?
Single-modhi faibha inokupa yakakwira yekutapurirana mwero uye inosvika makumi mashanu yakapetwa chinhambwe pane multimode, asi zvakare inodhura yakawanda.Single-mode fiber ine diki diki pane multimode fiber-kazhinji 5 kusvika 10 microns.Chete lightwave inogona kufambiswa panguva yakatarwa.Iyo diki musimboti uye imwechete lightwave inobvisa chero kukanganisa kunogona kuguma kubva mukupindirana kwechiedza pulses, ichipa iyo shoma chiratidzo chekudzikisira uye yakanyanya kumhanyisa kumhanya kwechero fiber cable mhando.
Multimode faibha inokupa yakakwira bandwidth pakumhanya kwakanyanya pamusoro pemarefu madaro.Malightwaves anoparadzirwa munzira dzakawanda, kana modhi, sezvaanofamba nepakati petambo.Typical multimode faibha musimboti madhayamita ari 50, 62.5, uye 100 micrometers.Zvisinei, mukumhanya kwetambo refu (kupfuura mamita 3000 [914.4 ml), nzira dzakawanda dzechiedza dzinogona kukonzera kukanganisa kwechiratidzo pamagumo ekugamuchira, zvichiita kuti data rive isina kujeka uye isina kukwana.
Kuedza uye certifying fiber optic tambo.
Kana iwe wakajaira certifying Category 5 tambo, iwe unozoshamisika nekufara kuri kuita certify fiber optic tambo sezvo kana usinga pindike mukukanganiswa kwemagetsi.Iwe unongoda kutarisa zviyero zvishoma:
• Attenuation (kana decibel kurasikirwa) -Kuyerwa mu dB / km, uku ndiko kuderera kwesimba rechiratidzo apo inofamba kuburikidza nefiber optic cable.• Kudzorera kurasikirwa-Kuwanda kwechiedza chinoratidzwa kubva kumucheto kure kwetambo kudzokera kunzvimbo.Iyo yakaderera nhamba, zviri nani.Semuenzaniso, kuverenga kwe -60 dB kuri nani pane -20 dB.
• Graded refractive index-Inoyera kuti chiedza chakawanda sei chinotumirwa pasi fiber.Izvi zvinowanzoyerwa pamawavelength e850 uye 1300 nanometers.Kuenzaniswa nemamwe ma frequency ekushanda, aya mazinga maviri anopa kuderera kwesimba kurasikirwa.(Cherechedza Izvi zvinoshanda kune multimode fiber chete.)
• Propagation kunonoka-Iyi ndiyo nguva inotora chiratidzo kufamba kubva pane imwe nzvimbo kuenda kune imwe pamusoro penzira yekufambisa.
• Nguva-domain reflectometry (TDR) -Inotumira mapuruzi epamusoro-frequency patambo kuitira kuti uongorore zvinoratidzira pamwe chete netambo uye kupatsanura kukanganisa.
Kune akawanda fiber optic testers pamusika nhasi.Basic fiber optic testers inoshanda nekupenya mwenje pasi kumucheto kwetambo.Kune rumwe rutivi, kune mugamuchiri akaenzaniswa kusimba rechiedza chechiedza.Neiyi bvunzo, unogona kuyera kuti ingani chiedza chiri kuenda kune imwe mugumo wetambo.Kazhinji, vaedzi ava vanokupa mibairo mumadecibel (dB) akarasika, ayo aunozoenzanisa nebhajeti rekurasikirwa.Kana kurasikirwa kwakayerwa kuri kushoma pane nhamba yakaverengerwa nebhajeti rako rekurasikirwa, kuisirwa kwako kwakanaka.
Newer fiber optic testers vane huwandu hwakawanda hwekugona.Ivo vanogona kuyedza ese ari maviri 850- uye 1300-nm masiginecha panguva imwe chete uye vanogona kunyange kutarisa Gable yako kuti inoenderana neyakasiyana zviyero.
Nguva yekusarudza fiber optic.
Kunyangwe fiber optic tambo ichiri kudhura kupfuura mamwe marudzi etambo, inofarirwa kune yanhasi-yekumhanya data kutaurirana nekuti inobvisa matambudziko eakamonyoroka-pair cable, senge pedyo-end crosstalk (NEXT), electromagnetic interference (EIVII), uye kuchengetedza kutyora.Kana iwe uchida iyo fiber tambo unogona kushanyirawww.mireko-cable.com.
