Ngu Admin / 28 Oct 20 /0Amagqabantshintshi Intshayelelo kwisixhobo semodem yefiber optic yasekhaya, iitransceivers zefiber optic kunye nezitshintshi zephotoelectric Ngaba ifayibha yamehlo ingaguqula intambo yenethiwekhi? Ifayibha ye-Optical luhlobo lwefiber yeglasi ye-optical, ehambisa izibonakaliso ze-optical kwaye ayikwazi ukudibanisa ngokuthe ngqo kwintambo yenethiwekhi. Kufuneka kusetyenziswe izixhobo zokuguqula i-photoelectric ukuguqula imiqondiso ye-optical kwimiqondiso yenethiwekhi. Ukhetho oluqhelekileyo lwefoto...

I-fiber optic transceiver ihambelana ngokupheleleyo ne-IEEE802.3, IEEE802.3u, kunye nemigangatho ye-IEEE802.1d. Ixhasa iindlela ezintathu zokusebenza: i-duplex epheleleyo, i-half duplex, kunye ne-adaptive. Gigabit ukhethe...

Ke, ngaba uyawazi umahluko phakathi kwezi zintathu zicacileyo? Imodem yokubona luhlobo lwezixhobo... Funda ngokugqithisileyo NguMlawuli / 12 Oct 20 /0Amagqabantshintshi Yintoni umahluko phakathi kwe-single-fiber-fiber kunye nemowudi enye yee-transceivers optical optical mode enye-nye? I-Optical fiber transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye nemiqondiso yokubona ekude. Ngokweemfuno zayo, ihlulwe kakhulu ibe yi-fiber optical transceivers kunye ne-dual-fiber optical transceivers.Okulandelayo...
