Isakhiwo sezintambo ze-optical siyathuthuka kanye nokuthuthukiswa kwamanethiwekhi e-optical kanye nezidingo zendawo yokusebenza. Isizukulwane esisha samanethiwekhi e-optical aphelele sidinga izintambo ze-optical ukuze zinikeze i-bandwidth ebanzi kanye nokusekelwa...

1. Ilula: Isakhiwo asingeni moya futhi sinomklamo ohlukile womsele, okwenza ukuxhumana kube lula futhi kube lula ukufakwa nokugcinwa. 2. Ikhebula le-optical laklanywa ngokukhethekile ngohlangothi olunwebekayo, olufanele...

1. Ikhebula Lenethiwekhi Lesigaba 5: Ikhebula Lesigaba 5 lisekela isivinini sokudlulisa esingu-100 Mbps futhi lithathelwe indawo yikhebula Lesigaba 5; imvamisa yesiginali edluliselwa yikhebula Lesigaba 5 ingu-100 MHz futhi isivinini...

(1) Ukuhlanganiswa: Ukufakwa kwezintambo ehhovisi kumele kuhlangabezane nezidingo zokudlulisa zezimpawu ezahlukene ze-analog noma zedijithali, futhi kuhlanganiswe lonke ulimi, idatha, isithombe, kanye nokufakwa kwezintambo zemishini yokuqapha ohlelweni olujwayelekile lwezintambo ze-E...

(1) Ithusi elimsulwa. Ithusi elimsulwa liyikhebula lenethiwekhi elingcono kakhulu nelisezingeni eliphezulu. Lifanelekela izinsiza zikagesi ze-PoE futhi linokumelana okuphansi ukuvimbela ukulahleka kwamandla ngesikhathi sokudlulisa. Lolu hlobo lwekhebula lenethiwekhi luyikhebula elingcono kakhulu...

1. Hlola Umbala: Okokuqala, vula ijakhethi yangaphandle yekhebula lenethiwekhi bese ulihlola. Manje usungakwazi ukubona izintambo zenethiwekhi zihlangene bese uziqhathanisa ngokucophelela. Uma izintambo eziluhlaza nezimhlophe kanye nezintambo eziluhlaza nezimhlophe...

I-GY--Ikhebula le-fiber optic langaphandle i-GJ--Ikhebula le-optical langaphakathi i-MG--Ikhebula le-optical lemayini yamalahle II. Izinhlobo zezinto eziqinisayo (akukho modeli)--Ilungu lokuqinisa insimbi F--Ilungu lokuqinisa elingeyona insimbi III. Izici zesakhiwo...

Izici eziyinhloko ezibangela ukuncishiswa kwefayibha yilezi: izici zangaphakathi, ukugoba, ukuphuma, ukungcola, ukuntuleka kokufana, kanye nokuhlangana. 1. Ingaphakathi: Lokhu ukulahlekelwa okungokwemvelo kwefayibha, okuhlanganisa: Ukusabalala kweRayleigh, ukumuncwa...

Inzuzo 1. Amandla aphezulu okumelana nezimo zezulu ezimbi kakhulu (imimoya enamandla, isichotho, njll.). 2. Ukuzivumelanisa nezimo zokushisa okunamandla kanye ne-coefficient encane yokwanda okuqondile ukuze kuhlangatshezwane nezidingo zezimo ezinzima...

Ngokusekelwe ezingxenyeni ezahlukene kanye nezakhiwo ze-OPGW, i-OPGW ihlukaniswe kanje. 2.1 Ngokwezinto ezisetshenziswayo zepayipi elivikelayo leyunithi yokukhanya, uhlobo lwesakhiwo se-OPGW luhlukaniswe ngepayipi le-OPGW lensimbi engagqwali kanye...

1. Izintambo ze-fiber optic zasemoyeni zisetshenziswa kakhulu emigqeni yesibili yesiqu kanye nezintambo zekhebula ze-fiber optic ezingaphansi komhlaba, futhi zifanele izindawo ezinesimo esiyisicaba kanye nokuguquguquka okuncane kwamandla kagesi. 2. Kunezindlela ezimbili zokumiswa...

I-fiber yemodi eyodwa (i-fiber yemodi eyodwa): ukukhanya kungena ku-fiber nge-engeli ethile yokwenzeka, futhi ukukhishwa okuphelele kwenzeka phakathi kwe-fiber kanye ne-cladding. Uma ububanzi bubuncane, ukukhanya kuvunyelwe kuphela ukudlula ohlangothini olulodwa...
