Mux Demux 4 Channel Coarse Wavelength Division Multiplexing CWDM LGX box type LC/UPC Connector

-Mu itumanaho rya fibre-optic, WDM ni ikoranabuhanga rikoresha uburyo bwo kongera ibimenyetso byinshi by’urumuri rw’amashanyarazi ku rumuri rumwe rw’amashanyarazi hakoreshejwe uburyo butandukanye bw’urumuri rwa laser. Ubu buryo butuma habaho itumanaho ry’uburyo bubiri hejuru y’urumuri rumwe rw’urumuri rw’amashanyarazi, ndetse no kongera ubushobozi bw’urumuri rw’amashanyarazi.

-Izina ryuzuye rya CWDM ni Coarse Wavelength Division Multiplexing.

-Nkuko izina ribivuga, ni ubwoko bwa fiber optique nyinshi, bityo imiyoboro ya CWDM ishobora kohereza itumanaho icyarimwe, mu buryo bubiri.

-Ijambo "coarse" risobanura intera y'uburebure bw'umuraba hagati y'imiyoboro.

-CWDM ikoresha ibimenyetso bya lazeri bitandukanye mu nyongera ya 20 nm. Hari imiyoboro 18 itandukanye — ifite uburebure bw'uburebure kuva kuri 1610 nm kugeza 1270 nm — kandi 8 ishobora gukoreshwa muri sisitemu imwe. Kubera ko buri muyoboro ushobora gutanga amakuru angana na 3.125 Gbps, ubushobozi rusange ni 10 Gbps kuri insinga iyo ari yo yose ya CWDM.

-CWDM ikoreshwa mu gukoresha igiciro gito, ubushobozi buke (sub-10G) no mu ntera ngufi aho ikiguzi ari ikintu cy'ingenzi.

-CWDM ni nziza cyane ku miyoboro yihuta kandi miremire idakenera umuvuduko uhenze cyane. Ni nziza kandi mu kuvugurura buhoro buhoro sisitemu zishaje.

-CWDM ishobora kuba umurongo wawe woroshye utuma amahitamo yawe aguma afunguye, ariko ushobora no gukoresha izindi nsinga aho bibaye ngombwa.
