Imibuzo Evame Ukubuzwa
Uyini umehluko phakathi kwezintambo ze-OM3 ne-OM4?
Izintambo ze-OM4 zinikeza i-bandwidth ephezulu (4700 MHz·km) kanye nokusekelwa kwebanga elide (amamitha angu-550 ku-10 Gbps) uma kuqhathaniswa nezintambo ze-OM3, ezinikeza i-2000 MHz·km kanye namamitha angu-300.
Ingabe izintambo ze-fiber ze-multimode zingasetshenziswa ekusetshenzisweni kwangaphandle?
Yebo, izintambo ze-multimode ezilinganiselwe ngaphandle ezinamajakethi okuvikela, njenge-polyethylene (PE), ziyamelana nokuchayeka kwe-UV, umswakama, kanye namazinga okushisa aphezulu, okwenza zifaneleke ezindaweni zangaphandle.
Icebiso:Njalo qinisekisa uhlobo lwejakethi yekhebula kanye nezilinganiso zemvelo ngaphambi kokusebenzisa ngaphandle.
Ngiqinisekisa kanjani ukuthi iyahambisana nezinhlelo zenethiwekhi ezikhona?
Ishekeizinhlobo zezixhumi(isb., i-LC, i-SC, i-MTP/MPO) futhi uqinisekise ukuthi ziyahambisana nezidingo zesistimu. Hlola ukulahleka kokufakwa kanye nezilinganiso zokulahlekelwa kokubuyiselwa ukuze ugcine ubuqotho besiginali.
