Abasebenzisi abaningi bazothola ukuthi ngemva kwezilungiselelo ezifanele ngemuva kwerutha engenantambo, ukusetshenziswa kweselula ukuze kuxhunywe inethiwekhi engenantambo, kodwa bathole ukuthi kunamagama amabili esignali ye-WiFi, isignali ye-WiFi eyodwa iyi-2.4G yendabuko, nelinye igama. kuzolandelwa uphawu lwe-5G, kungani...

Inethiwekhi yokufinyelela okubonakalayo (okungukuthi, inethiwekhi yokufinyelela enokukhanya njengendlela yokudlulisa, esikhundleni sezintambo zethusi, isetshenziselwa ukufinyelela umndeni ngamunye. Inethiwekhi yokufinyelela optical).Inethiwekhi yokufinyelela optical ngokuvamile iqukethe izingxenye ezintathu: optical line terminal OLT, optical network. iyunithi ONU, ukusabalalisa okubonakalayo...

Iningi lemicu ye-optical esivame ukuyibona i-optical fiber jumpers, okungukuthi, zombili iziphetho zinezixhumi, ezingafakwa ngokuqondile futhi zisuswe ngaphandle kokusebenzisa amanye amathuluzi, okuthiwa isixhumi sibhekisela ku-SC, FC, LC nezinye izinhlobo zokuhlukaniswa. . Futhi uyini umnyombo, njengoba negama lisho ...

I-Fast Ethernet (FE) igama le-Ethernet kunethiwekhi yekhompyutha, ehlinzeka ngezinga lokudlulisa elingu-100Mbps. Izinga le-IEEE 802.3u 100BASE-T Fast Ethernet yethulwa ngokusemthethweni yi-IEEE ngo-1995, futhi izinga lokudlulisela le-Ethernet esheshayo ngaphambili lalingu-10Mbps...

I-Ethernet ubuchwepheshe benethiwekhi yendawo yekhompyutha, obusetshenziswa kakhulu ukuxhuma amasistimu amaningi enethiwekhi ukuze kuzuzwe inethiwekhi yendawo (LAN). Kunezinhlobo eziningi ze-Ethernet emakethe, okuyi-Ethernet esheshayo ne-Gigabit Ethernet ezivame kakhulu. Ngokushesha u-Eth...

Ukuhlolwa kokushintsha kwe-Gigabit kanye nokushintsha kwe-gigabit eyi-10 akuveli kuphela ekuhlolweni okuhlangene kweswishi, kodwa kudingeka kuhlolwe ububanzi obugcwele. Okulandelayo ikakhulukazi ukukhuluma mayelana nokuphuma, isikhathi sokulibaziseka kokudluliselwa, iphrothokholi nezici kanye nokungadingeki ngokwemibandela ye-gi. .
