      Ulwazi oluyisisekelo ngama-fiber optic transceivers

      1.1 Imojula yomsebenzi oyisisekelo I-transceiver ye-fiber optical ihlanganisa amamojula amathathu ayisisekelo asebenzayo: i-chip ye-photoelectric media conversion chip, isixhumi esibonakalayo sesignali ye-optical (imoduli ehlanganisiwe ye-transceiver optical) kanye ne-interface yesignali kagesi (RJ45). Uma ifakwe imisebenzi yokuphatha inethiwekhi, iphinde ihlanganise...

      Ukuhlaziywa kwamazinga obuchwepheshe be-fiber fusion optical

      I-Optical fiber fusion splicing process Izindlela zokuxhumanisa i-Optical fibre zingahlukaniswa zibe izinhlobo ezimbili: enye iyindlela yokuxhuma unomphela engakwazi ukuhlakazwa futhi ihlanganiswe uma isixhunyiwe, kanti enye iyindlela yokuxhuma isixhumi esingahlakazwa ngokuphindaphindiwe futhi sihlanganiswe...

      Ubuchwepheshe bokushintsha i-POE kanye nesingeniso sezinzuzo

      Iswishi ye-PoE iswishi esekela ukunikezwa kwamandla kukhebuli yenethiwekhi. Uma kuqhathaniswa neswishi evamile, itheminali yokwamukela amandla (njenge-AP, ikhamera yedijithali, njll.) ayidingi ukuxhunywa ngentambo ukuze kunikezwe amandla, futhi ukwethembeka kwayo yonke inethiwekhi kuphakeme. Umehluko phakathi kwe-P...

      Iyini i-optical splitter futhi yiziphi izinkomba ezibalulekile zobuchwepheshe?

      I-optical splitter ingenye yezinsiza ezibalulekile zokungenzi lutho kusixhumanisi se-fiber optical, futhi idlala kakhulu indima yokuhlukanisa. Ngokuvamile isetshenziswa kutheminali yomugqa obonayo we-OLT kanye netheminali yenethiwekhi yokubona i-ONU yenethiwekhi ye-passive optical ukuze kubonakale ukuhlukana kwesignali yokubona. I-op...

      Ukuhlaziywa okuphelele komehluko phakathi kwama-fiber jumpers nama-pigtails kanye nezinyathelo zokuphepha zokusetshenziswa

      Kunezinhlobo eziningi zezintambo ze-patch kanye ne-pigtails. Kuyaphawuleka ukuthi i-fiber pigtails kanye nezintambo ze-patch aziwona umqondo. Umehluko omkhulu phakathi kwezintambo ze-fiber optic patch kanye ne-fiber optic pigtails ukuthi ukuphela kwendawo eyodwa kuphela kwe-fiber optic pigtail enesixhumi esinyakazayo, futhi zombili izingxenye ze ...

      Yini okufanele ngiyenze uma izinga lokushisa lemojula ye-optical liphezulu kakhulu? Indlela yokuxazulula?

      Imojuli ye-optical idivayisi yokubona ebucayi kakhulu. Uma izinga lokushisa lokusebenza lemojula ye-optical liphezulu kakhulu, lizodala izinkinga ezifana namandla okudlulisa amehlo amaningi, iphutha lesignali elitholiwe, ukulahlekelwa kwephakethe, njll., futhi kushise imodyuli ye-optical ngokuqondile ezimweni ezinzima. Uma t...
