Menene CWDM?
-A cikin sadarwa ta fiber-optic, yawan rarrabawa tsakanin raƙuman ruwa (WDM) fasaha ce da ke ninka siginar ɗaukar hoto da yawa a kan fiber na gani ɗaya ta amfani da raƙuman ruwa daban-daban (watau launuka) na hasken laser. Wannan dabarar tana ba da damar sadarwa ta hanyoyi biyu a kan zaren fiber guda ɗaya, wanda kuma ake kira duplexing na tsawon rai-rabi, da kuma ninka ƙarfin aiki.
-Cikakken sunan CWDM shine Coarse Wavelength Division Multiplexing.
-Kamar yadda sunan ya nuna, nau'i ne na fiber optics masu yawa, don haka hanyoyin sadarwa na CWDM zasu iya aika sadarwa ta hanyoyi biyu a lokaci guda.
-Kalmar "mai kauri" tana nufin tazarar tsawon rai tsakanin tashoshi.
-CWDM yana amfani da siginar laser waɗanda suka bambanta a cikin ƙaruwa na 20 nm. Jimillar tashoshi 18 daban-daban suna samuwa - tare da kewayon tsawon rai daga 1610 nm zuwa 1270 nm - kuma ana iya amfani da 8 a cikin tsarin guda ɗaya. Tunda kowane tasha yana da ikon adadin bayanai na 3.125 Gbps, ƙarfin jimlar shine 10 Gbps ga kowane kebul na CWDM.
-Ana amfani da CWDM don ƙananan farashi, ƙarancin ƙarfin aiki (ƙasa da 10G) da kuma gajeriyar aikace-aikacen nesa inda farashi muhimmin abu ne.
-CWDM ya dace da hanyoyin sadarwa masu sauri da tsayi waɗanda ba sa buƙatar saurin sauri mai tsada. Hakanan ya dace da haɓaka tsoffin tsarin a hankali.
-CWDM na iya zama layin da zai iya sa zaɓuɓɓukanka su buɗe, amma har yanzu zaka iya amfani da wasu ƙirar kebul inda buƙatar hakan ta taso.
