Optical netambo: zvakanakira pane nekuipira

Munguva manonwe, zvakava mufashoni chaizvo kuva chiedza usiku mumba mokuvata, zvinosanganisira kuva hemispherical nechigadziko uye yakabudikira kubva waveguides danda. Rokuvaka iri nani chiedza nerima airatidza muchimiro Dots duku, ichipfuta panguva muromo mutete translucent fibers. Izvi chaizvoizvo yakanaka chinhu chakaitwa kubva tsvina ane mhando itsva mashoko vakapofumara. Doma navo - optic netambo (aka - installer, kureva faibha-optic kukurukurirana mitsetse).

FOL achishanda musimboti

Chero zvemagetsi kondakita ane nemishonga kushingaira kwete chete, asiwo reactive (capacitive uye inductive). Izvi parameters mumuviri novimba dhayamita ari waya, wave zvivako ayo, uye chokwadi mutsetse pakureba unobva chiratidzo yatumira pamwe nokupiwa mudziyo. Zvikurukuru nehanya resistive soro gwara yepamusoro yokukurukurirana makwara. Fiber-optic wire asina drawback ichi, icho nazvo duku zvikuru kupfuura kwakajairika conductors, nekuti mutakuri mashoko ari chiedza simba. mugero chiito musimboti zvakajeka uye zviri nyore. At Link mureza ndiwo chiyamuro, akarega nemagetsi kune Manyiminya. Panguva nzira yokubudisa pane ayo demodulation, uye inopinda mugamuchiri-mashoko mudziyo ane zvatinosiita voltage pulses.

Zvakanakira Fiber Channel

Kuwedzera kuramba kukanganiswa attenuation, Manyiminya netambo mamwe zvinokosha chaizvo zvakwaibatsira. Kana nokupfuuridzirwa mashoko pamusoro faibha migero nyore zvikuru kuti irambe zvakavanzika, nokuti zvisingaiti kubatanidza pachivande kwavari. Chimwe chakanakira nzira iyi kutapurirwa ndiko zvoupfumi. Copper - imwe simbi kudhura uye ruvara, ari waveguide zvinhu inokwanisika mutengo. The Manyiminya waya yakaitwa kubva Goldstone kana chinokosha polymer nziyo (fluoro-aluminate, kana fluoro-zirconate), uko (chiremera wechitatu) riri vakareruka kupfuura waya simbi kuti kunofanirawo firimu.

Manyiminya kutaurirana zvikanganiso

Hongu, Manyiminya netambo, uyewo zvose munyika muno, hakusi pasina zvainovhiringidzawo.

Chekutanga, kudzoreredza kukurukura remudunhu yakazaruka zvinoda yaitsiva yose zvakakuvadza nharaunda, haagoni spliced waveguides saka zvakakomba zvinowedzera mari navatengesi.

Chechipiri, kuti basa chokugadza ndiyewo haana kokupata mutengo. Nokuti Implementation dzavo vachifanira zvakarurama michini, uye zvinodhura. Uye unyanzvi zvaida, uye vanoda uye kubhadhara zvinoenderana.

Chechitatu, kuti akati chiratidzo convert panguva kwezvavakaisa goho mitsetse, uyewo connectors (namano kuti zvinopa nokuchinja), yakakwirira chaizvo zvinoda kuvimbwa, Manyiminya kurasikirwa zvakarurama. Kuti unhu ndewe mari, hapana anoda kutsanangura.

ramangwana Communication

Kunyange zvakadaro, zvakanakira zvakawanda. Optical netambo zvinogona kutapurira munhu Broadband chiratidzo, ayo yekudyidzana zvinowedzera kumhanya mashoko Exchange (akayera atova terabits muzana wechipiri). Kana attenuation iri duku zvikuru (pane imwe wavelength pamusoro 1,55 microns, ndiko 0,22 chete db / km). Uyezve, mano chiedza mafungu kufamba wakatarisana mirayiridzo (pamwe zvakasiyana polarization) mune imwe chete internet optic kondakita kunowedzera mikana. kuvandudzika wavo anoenderera.
