Yini i-PON?Ubuchwepheshe bokufinyelela ku-Broadband buyadlondlobala, futhi bumiselwe ukuba inkundla yempi lapho intuthu ingasoze yashabalala.Njengamanje, okujwayelekile kwasekhaya kusewubuchwepheshe be-ADSL, kepha bayanda abakhiqizi bemishini nabaqhubi baphendukele ku-optical network ac...

Ngokuthuthuka okuqhubekayo kobuchwepheshe bokuxhumana be-optical, ukuxhumana kwe-fiber optical kuhlangabezane nezizukulwane ezinhlanu kusukela ekubukeni kwayo.Ithuthukiswe kahle futhi yathuthukiswa kwe-OM1, OM2, OM3, OM4 kanye ne-OM5 fiber, futhi yenze impumelelo eqhubekayo kumthamo wokudlulisela kanye...

Kusukela ngasekupheleni kweminyaka yawo-1980, ukuxhumana kwe-fiber-optic kancane kancane kwashintsha kusuka kubude obufushane kuya kubude begagasi ende, kusuka ku-multimode fiber kuya ku-fiber yemodi eyodwa.Njengamanje, i-fiber yemodi eyodwa isetshenziswa kabanzi kunethiwekhi yesiqu sekhebula kazwelonke kanye nenethiwekhi yomugqa wesifundazwe.I-Multimode fiber iyi-li kuphela ...

Ingabe ama-transceiver e-fiber optic kufanele asetshenziswe ngababili?Ingabe kukhona ukuhlukana kwe-fiber transceiver?Noma ipheya nje yama-transceiver e-fiber optic angasetshenziswa ukwakha ipheya?Uma ama-fibre transceivers kumele asetshenziswe ngababili, ingabe iwuphawu olufanayo nemodeli?Noma ungasebenzisa noma iyiphi inhlanganisela ye-bran...

Imojula ye-Optical iyisisetshenziswa sehadiwe esibalulekile sokubona ukuxhumana kwenethiwekhi ye-optical kusikhungo sedatha.Ngokukhula kwenombolo ye-port kanye nokuminyana, izindleko zemodyuli ye-optical zizobala cishe ingxenye yezindleko zenethiwekhi ye-optical kusikhungo sedatha.Okwamanje, ubuchwepheshe bokuxhumanisa kwe-100G ...

I-“OM” ekuxhumaneni kwamehlo ibhekisela “kumodi ye-Optical Multi-Mode”.Imodi ye-Optical, okuyindinganiso yefayibha ye-multimode ukukhombisa izinga lefiber.Okwamanje, i-TIA ne-IEC echazwe amazinga entambo ye-fiber patch yi-OM1, OM2, OM3, OM4, kanye ne-OM5.Okokuqala, yini i-multimode nemodi eyodwa?Cula...
