Ekufakeni i-fiber optical, ukulinganisa ngokuchanekileyo kunye nokubalwa kwe-fiber optical links kuyinyathelo elibaluleke kakhulu lokuqinisekisa ukunyaniseka kwenethiwekhi kunye nokuqinisekisa ukusebenza kwenethiwekhi. I-fiber optical iya kubangela ukulahleka kwesignali ebonakalayo (oko kukuthi, ukulahleka kwefiber optical) ngenxa yokutshatyalaliswa kokukhanya kunye nokusabalalisa, okuya kuchaphazela ukuthembeka kwenethiwekhi ye-optical transmission. Ke singalazi njani ixabiso lelahleko kwikhonkco lefiber? Eli nqaku liza kukufundisa ukubala ilahleko kwiikhonkco zefiber optic kunye nendlela yokugweba ukusebenza kwamakhonkco e-fiber optic.
Uhlobo lokulahleka kwefayibha: Ukulahleka kwefayibha kwaziwa ngokuba kukuthomalalisa ukukhanya, okubhekiselele kwisixa sokulahleka kokukhanya phakathi kwesiphelo sokudlulisa kunye nesiphelo sokufumana ifayibha. Kukho izizathu ezininzi zokulahleka kwefiber optical, njengokufunxa imathiriyeli yefiber optical / ukusasazwa kwamandla okukhanya, ilahleko yokugoba, ukulahleka kwesinxibelelanisi, njl.
Ukushwankathela, kukho izizathu ezibini eziphambili zokulahleka kwefiber optical: izinto zangaphakathi (oko kukuthi, iimpawu zendalo zefiber optical) kunye nezinto zangaphandle (oko kukuthi, okubangelwa kukungasebenzi kakuhle kwefiber optical), enokwahlulwa ibe yi-intrinsic optical. ilahleko yefiber kunye ne-non-intrinsic fiber optical loss. Ilahleko yefiber yangaphakathi luhlobo lwelahleko yendalo yefiber, ebandakanya ukulahleka kokufunxa, ilahleko yokusasazeka kunye nelahleko esasazwayo ebangelwa ziziphene zesakhiwo. Ilahleko yefiber engeyiyo ye-intrinsic ikakhulu ibandakanya ukulahleka kwe-welding, ukulahleka kwesinxibelelanisi kunye nokulahleka kokugoba.
ImiGangatho yokuLahleka kweFayibha: I-Telecommunications Industry Alliance (TIA) kunye ne-Electronic Industry Alliance (EIA) zisebenze kunye ukuphuhlisa umgangatho we-EIA/TIA, ochaza ukusebenza kunye neemfuno zothumelo lweentambo zamehlo kunye nezihlanganisi kwaye ngoku zamkelwe ngokubanzi kwaye zisetyenziswa ishishini lefiber optic. Imigangatho ye-EIA/TIA icacisa ukuba ukuthotywa okuphezulu yeyona parameters ibaluleke kakhulu kumlinganiselo wokulahleka kwefiber. Ngapha koko, eyona nto iphezulu yokuthomalalisa intambo yi-attenuation factor, kwi-dB/km. Lo mzobo ungezantsi ubonisa ukuthomalaliswa okuphezulu kweentlobo ezahlukeneyo zentambo kwi-EIA/TIA-568 yokucacisa umgangatho.
Uhlobo lwentambo ye-Optical Wavelength (nm) Ubuninzi bokunciphisa (dB/km) Ubuncinci be-bandwidth (Mhz * Km) 50/125 i-multimode 8503.550013001.550062.5 mu m / 125 microns multimode 8503.5160100 intambo ye-fiber eyodwa-50100 yomnyango omnye. 0-13101.0 yangaphandle eyodwa -mode intambo yefiber optical - 15500.5-13100.5
Ngentla sisingeniso somxholo jikelele wokulahleka kweFayibha ye-Optical, ndiyathemba ukukunceda kwimfuno.
Ukongeza kwiI-ONUuthotho, uthotho lwe-transceiver,OLTseries, Shenzhen HDV Photoelectron Technology Ltd. kwakhona ivelisa uthotho imodyuli, ezifana: imodyuli yonxibelelwano optical, imodyuli yonxibelelwano optical, imodyuli yenethiwekhi optical, imodyuli yonxibelelwano optical, imodyuli ifayibha optical, Ethernet imodyuli ifayibha optical, njl., inokubonelela ngeenkonzo ezisemgangathweni ezihambelanayo iimfuno ezahlukeneyo zabasebenzisi, wamkele utyelelo lwakho.
