Ama-optical fibers amashaneli anentambo adlulisa amasignali okubona.
Sibhekisela kumasignali kagesi angadingekile esiteshini njengomsindo. Umsindo ohlelweni lokuxhumana ubekwe phezulu esignali, futhi kunomsindo ohlelweni lokuxhumana lapho kungekho signali yokudlulisela, futhi umsindo uhlala ukhona ohlelweni lwezokuxhumana. Umsindo ungabonakala njengohlobo lokugxambukela esiteshini, okwaziwa nangokuthi ukuphazamiseka okungeziwe, ngoba ubekwe phezulu esignali. Umsindo uyingozi ekudluliselweni kwesignali, ungahlanekezela amasignali e-analog, wenze amaphutha kumasignali edijithali, futhi ukhawulele izinga lokudlulisela kolwazi.
Ngokokuhlukaniswa kwemithombo, umsindo ungahlukaniswa ngezigaba ezimbili: umsindo owenziwe umuntu nomsindo wemvelo. Umsindo we-anthropogenic ukhiqizwa imisebenzi yabantu, njengenhlansi evela kuma-drill kagesi kanye nogesi wesikhashana.amaswishi, inhlansi evela kumasistimu okushisa ezimoto, ukuphazamiseka kwamalambu e-fluorescent, nemisebe kazibuthe evela kwezinye iziteshi zomsakazo nezinto zikagesi. Umsindo wemvelo izinhlobonhlobo zemisebe kagesi ekhona emvelweni, njengombani (ukukhanya), umsindo womkhathi, kanye ne-cosmicnoise evela elangeni kanye nomthala (umthala). Ngaphezu kwalokho, kunomsindo wemvelo obaluleke kakhulu, okungukuthi, umsindo oshisayo. Umsindo oshisayo uvela ekuhambeni okushisayo kwama-electron kuzo zonke izingxenye eziphikisayo. Isibonelo, izintambo, ama-resistors, namadivayisi we-semiconductor wonke adala umsindo oshisayo. Ngakho-ke, umsindo oshisayo ukuyo yonke indawo futhi nakanjani ukhona kuwo wonke amadivaysi kagesi, ngaphandle uma idivayisi ikwizinga lokushisa le-thermodynamic Kulungile. Ezingxenyeni eziphikisayo, ama-electron amahhala ahlala enyakaza ngenxa yamandla awo ashisayo, ashayisana nezinye izinhlayiya ezihambayo futhi ahamba ngokungahleliwe ku-polygonal endleleni, okungukuthi, avela njengokunyakaza kwe-Brownian. Uma engekho amandla angaphandle, isilinganiso samanje esivela ekuhambeni kwe-Brownian kwalawa ma-electron silingana noziro, kodwa ingxenye yamanje ye-AC iyakhiqizwa. Le ngxenye ye-AC ibizwa ngokuthi umsindo oshisayo. Ibanga lefrikhwensi yomsindo oshisayo libanzi kakhulu, lisatshalaliswa ngokulinganayo cishe ukusuka eduze nefrikhwensi eyiziro kufika ku-102Hz.
Lena i-Shenzhen HDV phoeletron Technology Ltd. ukukulethela mayelana nendatshana "yomsindo esiteshini", ngethemba ukukusiza, i-Shenzhen HDV phoeletron Technology Ltd. iwumkhiqizo okhethekile wabakhiqizi bemishini yezokuxhumana, imikhiqizo eshisayo yokuxhumana yenkampani yile:I-ONUuchungechunge, uchungechunge lwe-transceiver,OLTuchungechunge, kodwa futhi ukukhiqizwa uchungechunge module, ezifana: Ukuxhumana module optical, optical zokuxhumana module, inethiwekhi module optical, zokuxhumana module optical, optical fibre module, Ethernet optical fibre module, njll, anganikeza isevisi izinga elihambisana kubasebenzisi ezahlukene. ' udinga, wamukele ukuvakasha kwakho.
