Kableeynta Coaxial Dheerka Raadiodka RF

Kabalka Coaxial ayaa ugu dhoweystay in ay noqdaan qodob aasaasiga ah ee xalka internet, gaar ahaan ee shabakada HFC (Hybrid Fiber Coaxial) oo waxa uu qabsaday adeegga kabalka modem ee dunida oo dhan. Tallaabada qorsho-eeysa ee isku mid ah jilaajilka heerarka sare, dielectric insulaadka ah, xidhmaha midabka ah, iyo jaarkhada miiska ah—wuxuu kuu celi karaa in uu soo saaray internet broadband iyo iskufoon teledifishanka ka duwan marka la isku dayo FDM (Frequency Division Multiplexing) si ay u gudbiyaan jirrada xilgaha. Nidaamka internet coaxial ee dheeraad ah ayaa socdaa qaybta DOCSIS (Data Over Cable Service Interface Specification), halka DOCSIS 3.1 uu ogola yahay cadadaha si ay u dhigiyaan 10 Gbps hoos ugu yimaada iyo 1 Gbps hoostii ka sare, waxaana la isbarbar dhigay fibirka qaar ka mid ah gobolada bulshada. Coaxial compared to Ethernet cables, waxay leeyihiin jirrada saxda ah ee badan (si ay u dhigiyaan boos laba koonfur) oo ku habboon yahay in la kala saaro, taas oo muuqda in ay noqdaan xal dhexe ee aasaasiga ah ee la taliyay. Xidhmaha heerarka sare waa muhim in cadada, sababtoo ah waxay kala saaridaa jadwalka ka soo horjeeda xidhmada jirrka ama iskufoonka laasiga ah, taas oo garanaya in xalka internet ay jirrada saxda ah ee la adeegayo si ay u ogolaadaan isku-dhismeedka video ama isku-dhismeedka. Si kastaba ha ahaatee, waxay coaxial ku jebin karaa awooddu marka la tixgelin yahay ama marka la isticmaalo xidhmada ugu danbeysan, taas oo sidaa darteed adeegsiiya ay u isticmaaliyaan kabalka oo kala soocan leh xidhmada heerarka sare, sida kabalka Hebei Mailing, si ay u kala saaro jirrada xilgaha. Gobolada dibedda, coaxial waxaa laga heley khalafka u dhexeeya DSL (dheer) iyo fibirka (qadhadhka badan), oo sidaa offer kuna leeyahay koros oo kala soocan. Fibirka optiikaska waxaa la rabay in la korosiyaa, coaxial waxaa laga filay in ay jirto habka soo saaridda ee la taliyay, fududka korosida, iyo la taliyadda ee MoCA (Multimedia over Coaxial Alliance) teknolojiiga, taas oo kala saaraya shabakada guriga oo dhan leh cadadaha gigabit. Iyada dhammaadka ah, in ay coaxial kabalka ee dalka ilaa modemka ay jirto xidhmada saxda ah iyo laga jaban yahay jadwalka waa muhim in ay korosiyaa awoodda internetka.
