O le a le faʻavae faʻavae o le wavelength division multiplexing system?

Optical wavelength division multiplexing o se tekinolosi e fa'asalalauina fa'ailoga mata'itusi tele-umi i totonu o le fiber optical e tasi.O le faʻavae autu o le tuʻufaʻatasia (multiplex) faʻailoga mataʻutia o galu eseese i le pito faʻasalalau, faʻapipiʻi i latou i le fiber opitika tutusa i luga o le laina uaea opitika mo le faʻasalalau, ma vavae ese (demultiplex) faʻailoga opitika o galu tuʻufaʻatasia i le pito e maua. ., ma fa'agasolo atili, o le ulua'i fa'ailoga e toe maua ma auina atu i fa'ailoga eseese.

WDM wavelength division multiplexing e le o se manatu fou.I le amataga o le faʻaalia o fesoʻotaʻiga fiber opitika, na iloa ai e tagata o le bandwidth tele o fiber optical e mafai ona faʻaaogaina mo le tele o galu umi, ae i luma o le 1990s, e leai se faʻalavelave tele i lenei tekinolosi.Atina'e vave Mai le 155Mbit/s i le 622Mbit/s i le 2.5Gbit/s System TDM fua faatatau ua fa'afaina i nai tausaga ua tuana'i E seasea ona ua'i atu tagata i se isi tekinolosi pe a alu saoasaoa se tasi tekinolosi I le 1995 O se mafuaaga taua mo le suiga i le O le atinaʻeina o le WDM system o tagata na feagai ma faʻalavelave i le TDM 10Gbit / s tekinolosi i lena taimi, ma le tele o mata na taulaʻi atu i le multiplexing ma le faʻaogaina o faailoilo mata.Naʻo le taimi lena na maua ai e le WDM le tele o faʻaoga i le lalolagi atoa..
