      Imbobo ye-Ethernet - RJ45

      Njengoba kuboniswe esithombeni esingenhla, singakuqonda ukubukeka kwe-RJ45 ngokusho kwesithombe, kodwa akuzona zonke izixhumanisi ze-RJ45 ezifana nalezi ezingenhla ziyi-interface ye-RJ11, okungeke kuxoxwe ngayo okwesikhashana. Amaswishi ahlelwe eceleni ngamachweba amaningi e-RJ45, angaba...

      Ukuhambisana kwamamojula we-Optical

      Ngokuvamile, ukuhambisana kwamamojula optical kubhekisela ekutheni amamojula angasebenza ngokujwayelekile yini ezintweni zokuxhumana zemikhiqizo ehlukene kanye nabakhiqizi. Okuqukethwe kobuchwepheshe bamamojula optical kuphansi, futhi isingeniso sabo silula. Ngenxa yalokho, abaningi ...

      Umgomo Wokusebenza Wokushintsha

      noma imodeli yereferensi ye-OSI, iswishi isebenza kungqimba lwesibili lwale modeli, isendlalelo sesixhumanisi sedatha. Njengoba kuboniswe emfanekisweni olandelayo, ukushintshwa kunamachweba ayisishiyagalombili. Uma idivayisi ixhunywe kuswishi nge-RJ45, i-chip eyinhloko yeswishi izohlonza izimbobo ezixhunywe kunethiwekhi...

      Isingeniso se-PON Module

      Imojuli ye-PON iwuhlobo lwemojuli yokubona. Isebenza kumishini yetheminali ye-OLT futhi ixhuma nemishini yasehhovisi ye-ONU. Kuyingxenye ebalulekile yenethiwekhi ye-PON. Amamojula we-PON optical angahlukaniswa abe amamojula we-APON (ATM PON), i-BPON (inethiwekhi ye-broadband passive) amamojula optical, i-EPON (Ethernet...

      Umgomo we-Frequency Hopping Spread Spectrum Communication (FHSS)

      I-FHSS, ubuchwepheshe be-frequency hopping spread spectrum, ngaphansi kwesimo sokuvumelanisa kanye nesikhathi esisodwa, yamukela amasignali adluliswa abathwali bebhendi emincane yohlobo oluthile (leli fomu elithile linemvamisa ethile, njll.) kuzo zombili iziphetho. Kumamukeli ongenalo uhlobo oluthile, i-hop...

      OFDM — 802.11 Incazelo Yephrothokholi

      I-OFDM iphakanyiswe ku-IEEE802.11a. Ngokusekelwe kule ndlela yokushintshashintsha, sidinga ukwazi ukuthi iyini i-OFDM ukuze siqonde izimiso ezihlukene. Yini i-OFDM? I-OFDM iwubuchwepheshe obukhethekile bokushintshwa kwezinkampani eziningi. Lobu buchwepheshe buhlose ukuhlukanisa isiteshi sibe iziteshi ezincane ze-orthogonal, futhi ...
