Yintoni imodyuli yokukhanya ye-DWDM?

I-Dense Wavelength Division Multiplexing (DWDM) iteknoloji ingasetyenziselwa kwiindawo ezahlukeneyo zothungelwano lonxibelelwano, kubandakanywa uthungelwano lwe-backbone olude, i-metropolitan area networks (MAN), uthungelwano lokufikelela kwiindawo zokuhlala, kunye neenethiwekhi zendawo zendawo (LAN).

Kwezi zicelo, ngakumbi i-MAN, i-plug-factor encinci ye-pluggable (SFP) kunye nezinye iintlobo zeemodyuli ze-optical zivame ukufakwa kwiifom ze-high-density form.Kungenxa yoko le nto abantu bejonge phambili kwi-DWDM transceivers optical kakhulu.Esi sifundo siya kukuxelela malunga nesishwankathelo seemodyuli ze-DWDM optical, kwaye sikwazise kwi-Beiyi Fibercom (WWW.F-TONE.COM) izisombululo zemodyuli ye-DWDM ye-optical module.

Yintoni imodyuli yokukhanya ye-DWDM?

Njengoko igama layo lisitshela, imodyuli ye-DWDM optical imodyuli ye-optical edibanisa iteknoloji ye-DWDM.Imodyuli ye-DWDM ye-optical module isebenzisa i-wavelengths eyahlukeneyo kwi-multiplex ye-optical signals kwi-fiber optical enye, kwaye lo msebenzi awudli naluphi na amandla.Ezi modyuli ze-optical zenzelwe umthamo ophezulu, ukuhanjiswa kwexesha elide, izinga linokufikelela kwi-10GBPS, kwaye umgama wokusebenza unokufikelela kwi-120KM.Ngelo xesha, imodyuli ye-DWDM ye-optical yenzelwe ngokweSivumelwano se-Multilateral Agreement (MSA) ukuze kuqinisekiswe uluhlu olubanzi lwezixhobo zenethiwekhi ezihambelanayo.Iimodyuli ze-10G ze-DWDM ze-optical zixhasa i-ESCON, i-ATM, i-Fiber Channel kunye ne-10 Gigabit Ethernet (10GBE) kwi-port nganye.Iimodyuli ze-DWDM optical kwimarike ngokuqhelekileyo ziquka: I-DWDM SFP, i-DWDM SFP +, i-DWDM XFP, i-DWDM X2 kunye ne-DWDM XENPAK iimodyuli ze-optical, njl.
