Mae Cebl Dan Do Dwbl Twin Dyblyg yn defnyddio ffibr byffer tynn 900μm neu 600μm gwrth-fflam fel cyfrwng cyfathrebu optegol.
Y ffibr byffer tynn wedi'i lapio â haen o edafedd aramid fel unedau aelod cryfder, mae uned o'r fath yn cael ei allwthio â haen o ddeunydd PVC neu LSZH fel siaced fewnol.
Yna cwblheir y cebl gyda haen o siaced fflat PVC neu LSZH (Mwg isel, Zero halogen, Fflam-retardant) fel gwain allan.
