A cikin bincike da ci gaba da sababbin fasahohin fiber na gani, SDM rarraba sararin samaniya ya jawo hankalin mai yawa.Akwai manyan hanyoyi guda biyu don aikace-aikacen SDM a cikin filaye na gani: core division multiplexing (CDM), wanda aka gudanar da watsawa ta hanyar ginshiƙan filaye mai mahimmanci. Ko Yanayin Rarraba Multiplexing (MDM), wanda ke watsa ta hanyoyin yaduwa na ƴan-yanayin-yanayin ko fiber-mode multi-mode.
Core Division Multiplexing (CDM) fiber yana cikin ka'ida dangane da amfani da manyan tsare-tsare guda biyu.
Na farko yana dogara ne akan yin amfani da ƙunƙun fiber guda ɗaya (fibre ribbons), wanda a cikin layi ɗaya ana haɗa zaruruwan yanayi guda ɗaya don ƙirƙirar dauren fiber ko ribbons waɗanda zasu iya samar da ɗaruruwan layi ɗaya.
Zabi na biyu ya dogara ne akan isar da bayanai akan cibiya guda ɗaya (yanayin guda ɗaya a kowace sahihanci) wanda aka saka a cikin fiber iri ɗaya, watau a cikin fiber multicore MCF. Ana kula da kowace cibiya azaman tasha ɗaya ce dabam.
MDM (Module Division Multiplexing) fiber yana nufin watsa bayanai akan nau'ikan fiber na gani daban-daban, kowannensu ana iya ɗaukarsa azaman tashoshi daban.
