Ekufakweni kwe-fiber optical, ukulinganisa okunembile nokubala kwezixhumanisi ze-fiber optical kuyisinyathelo esibaluleke kakhulu sokuqinisekisa ubuqotho benethiwekhi nokuqinisekisa ukusebenza kwenethiwekhi. I-fiber optical izobangela ukulahlekelwa kwesignali okusobala (okungukuthi, ukulahlekelwa kwe-fiber optical) ngenxa yokumunca ukukhanya nokusabalalisa, okuzothinta ukwethembeka kwenethiwekhi yokudlulisa optical. Ngakho-ke singalazi kanjani inani lokulahlekelwa kusixhumanisi se-fiber? Lesi sihloko sizokufundisa ukuthi ubala kanjani ukulahlekelwa kuzixhumanisi ze-fiber optic nokuthi ungahlulela kanjani ukusebenza kwezixhumanisi ze-fiber optic.
Uhlobo lokulahleka kwefayibha: Ukulahleka kwefayibha kubuye kwaziwe njengokuncishiswa kokukhanya, okubhekisela enanini lokulahlekelwa ukukhanya phakathi kwesiphetho sokudlulisa kanye nesiphetho sokwamukela sefayibha. Kunezizathu eziningi zokulahleka kwefiber optical, njengokumuncwa/ukuhlakazwa kwamandla okukhanya, ukulahleka kokugoba, ukulahleka kwesixhumi, njll.
Ukufingqa, kunezizathu ezimbili eziyinhloko zokulahleka kwe-fiber optical: izici zangaphakathi (okungukuthi, izici zemvelo ze-fiber optical) kanye nezici zangaphandle (okungukuthi, ezibangelwa ukusebenza okungalungile kwe-fiber optical), ezingahlukaniswa zibe intrinsic optical. ukulahleka kwefiber kanye nokulahleka kwefiber optical okungeyona eye-intrinsic. Ukulahleka kwefayibha engaphakathi kuwuhlobo lokulahlekelwa okungokwemvelo kwezinto zefayibha, okubandakanya ikakhulukazi ukulahlekelwa ukumuncwa, ukulahlekelwa kokuhlakazeka nokulahlekelwa okuhlakazekayo okubangelwa ukukhubazeka kwesakhiwo. Ukulahleka kwefayibha engeyona eye-intrinsic ikakhulukazi kufaka phakathi ukulahleka kokushisela, ukulahleka kwesixhumi nokulahlekelwa ukugoba.
Amazinga Okulahleka Kwe-Fiber: I-Telecommunications Industry Alliance (TIA) kanye ne-Electronic Industry Alliance (EIA) basebenze ndawonye ukuze kuthuthukiswe izinga le-EIA/TIA, elicacisa ukusebenza nokudluliselwa kwezidingo zezintambo nezixhumi futhi manje sesamukelwa kabanzi futhi sisetshenziswa imboni ye-fiber optic. Amazinga e-EIA/TIA acacisa ukuthi ukuncishiswa okuphezulu kungenye yemingcele ebaluleke kakhulu esilinganisweni sokulahleka kwefayibha. Eqinisweni, ukuncishiswa okuphezulu kuyisici sokunciphisa ikhebula, ku-dB/km. Isibalo esingezansi sibonisa ukuncishiswa okuphezulu kwezinhlobo ezahlukene zekhebula kuzinga lokucaciswa kwe-EIA/TIA-568.
Uhlobo lwekhebuli yokubuka i-Wavelength (nm) Ukunciphisa okuphezulu (dB/km) Umkhawulokudonsa omncane (Mhz * Km) 50/125 i-multimode 8503.550013001.550062.5 mu m / 125 microns multimode 8503.5160100 intambo engu-single o130 intambo engu-516010010101010 womnyango owodwa. 0-13101.0 eyodwa yangaphandle -Imodi ye-fiber optical cable - 15500.5-13100.5
Ngenhla isingeniso esijwayelekile sokuqukethwe sokulahleka kwe-Optical Fiber, ngithemba ukukusiza oswele.
Ngaphezu kwe-I-ONUuchungechunge, uchungechunge lwe-transceiver,OLTuchungechunge, i-Shenzhen HDV Photoelectron Technology Ltd. futhi ikhiqiza uchungechunge lwamamojula, njengalokhu: imojula yokuxhumana ye-optical, imojula yokuxhumana optical, inethiwekhi ye-optical module, imojula yokuxhumana ye-optical, i-optical fibre module, i-Ethernet optical fiber module, njll., ingahlinzeka ngezinsizakalo zekhwalithi ezihambisanayo izidingo zabasebenzisi abahlukene, wamukele ukuvakasha kwakho.
