Yintoni IPTV? Yintoni i-IPTV Iimpawu kunye neZibonelelo?
Kweli nqaku siza kwazi ukuba yintoni i-IPTV iimpawu zayo kunye neenzuzo zayo. I-IPTV ngumabonwakude osebenzisanayo wenethiwekhi, obubuchwephesha obutsha obusebenzisa inethiwekhi ye-TV ye-broadband kunye nokudibanisa ubuchwephesha obahlukeneyo obunje nge-Intanethi, imultimedia, kunye nonxibelelwano...Funda ngokugqithisileyo - NguMlawuli / 26 Jul 22 /0Amagqabantshintshi
Ulwazi oluSisiseko malunga ne-GPON imodyuli yokubona
Namhlanje, kunye nokuphucula okuqhubekayo kunye nokuphuculwa kweemodyuli ze-fiber optical, i-PON (i-passive optical fiber network) ibe yindlela ebalulekileyo yokuthwala iinkonzo zenethiwekhi yokufikelela kwi-broadband. I-PON yohlulwe kwi-GPON kunye ne-EPON. I-GPON kunokuthiwa yinguqulelo ephuculweyo ye-EPON. Eli nqaku, etu-l...Funda ngokugqithisileyo - Ngu Admin / 25 Jul 22 /0Amagqabantshintshi
Umsebenzi wemodyuli ye-Optical FEC
Ngophuhliso lwenkqubo yonxibelelwano lwe-optical kunye nomgama omde, umthamo omkhulu kunye nesantya esiphezulu, ngakumbi xa isantya se-wave wave sivela kwi-40g ukuya kwi-100g okanye nakwi-super 100g, i-chromatic dispersion, i-nonlinear effect, i-polarization mode dispersion kunye nezinye iziphumo zokuhambisa kwi-op. .Funda ngokugqithisileyo - Ngu Admin / 22 Jul 22 /0Amagqabantshintshi
GPON FTTx iqumrhu lomsebenzi
