Mhedziso

Nheyo ye fiber optic cable inoshanda sehwaro hwekutumira data nekukurumidza uye kwakavimbika. Ingava ukobvu, zvinhu, kana tekinoroji, chikamu chimwe nechimwe chepakati chinokanganisa kumhanya, kujeka, uye kushanda zvakanaka. Kusarudza mhando yepakati yakakodzera, kutevedzera maitiro akakodzera ekuisa, uye kugara uchiziva tekinoroji iri kubuda kuchakubatsira kuwana mhedzisiro yakanaka. Nekudzora mhando uye hunyanzvi hunoramba huchiuya, zvichisimudzira fiber optics zvakanyanya, tambo ye fiber optic yave chinhu chakakosha mukutaurirana kwemazuva ano.

Ungave uri kuronga kubatana kwekupedzisira kana kuti kuendeswa kwenyika yese, kuziva zviri pasi penyaya yekushambadzira kuchakubatsira kuti uite sarudzo dzakangwara. Fiber optics isayenzi yekururama uye mashandiro, uye musimboti ndiwo musimboti wesainzi. Kuti uve nechokwadi chekubatana nekukurumidza uye kwakavimbika uye kufamba kwedata kwakanaka, zvinobatsira kuisa mari mumusimboti wakakodzera.

Mibvunzo Inowanzo bvunzwa

Chii chinonzi musimboti wetambo ye fiber optic?

Chinoumba musimboti igirazi rakatetepa, repakati kana tambo yepurasitiki yetambo yefiber optic. Ndicho chikamu chetambo yefiber optic chinotakura zviratidzo zvechiedza kuti zvitumire data. Hunhu nehukuru hwechinoumba musimboti zvakakosha mukuita kuti data rakawanda rifambiswe zvakanaka.

Chinhu chikuru chinokanganisa sei kutapurirana kwedata?

Musoro unoshanda senzira iyo masaini echiedza anopfuura nayo kuti atumire data. Musoro ukajeka uye wakasimba, data rinogona kutumirwa nekukurumidza uye zvakavimbika kuburikidza nefibers pasina kurasikirwa nedata kana kukanganiswa kushoma.

Ndeupi musiyano uripo pakati pema "single-mode" nema "multi-mode" cores?

Macore emhando imwe chete anogadzira ray imwe chete inoburitsa, akatetepa (anenge 8-10 microns) uye anonyanya kukodzera madaro marefu. Macore emhando dzakawanda anopa macore makuru (50-62.5 microns) uye anoshandiswa kumadaro mapfupi ane bandwidths yakakwirira.

Ndezvipi zvinhu zvinokanganisa mashandiro e fiber optic core?

Kushanda zvakanaka kwepakati kunokanganiswa nehunhu hwezvinhu, kuchena, kunyatsoita dhayamita yepakati, uye kuiswa muchubhu yetambo. Kunyangwe zvinhu zvekunze, zvakaita sekuti tambo yakakombama kana kutatamuka iri kushandiswa, zvinogona kukanganisa mashandiro ayo.

Hunhu hwepakati hunodzorwa sei panguva yekugadzira?

Vagadziri vanovimba nemidziyo yekudhirowa fiber yemazuva ano kuti vave nechokwadi chekuti dhayamita yepakati yakarurama, kuchena kwezvinhu, uye kuvimbika kwekristaro. Kuedza kwakasimba kunovimbisa kushanda zvakanaka uye kutevedzera mitemo yeANSI/TIA.

Kuisa zvisina kunaka kunogona kukanganisa fiber optic core here?

Ehe. Kukombama zvakanyanya kana kudzvanywa kunoshandiswa pa fiber optic cable core panguva yekuisa kunogona kutyora kana kukanganisa core, zvichikonzera kurasikirwa kwechiratidzo kana kukanganiswa. Kutevedzera nzira dzakanakisisa ndiko kwakakosha.

Ndezvipi zvitsva zvitsva zviri kuitika mu fiber optic core technology?

Pakati pekufambira mberi kwazvino pane ma cores asingakanganisi ma "bend-insensitive cores", kugona kwepamusoro kwe "bandwidth", uye zvinhu zvinochengetedza nharaunda. Izvi zvitsva zvinotarisa pakuwedzera kugara kwenguva refu, kushanda zvakanaka, uye kugara kwenguva refu. Zvakakodzera zvakakwana kune network dzedata dziri kuramba dzichikura nhasi.
