ukubeka:i-structural reinforcement strip, intambo enentambo emaphakathi, intambo engaphandle, indandatho eshumekiwe, ipuleti elihlanganyelwe elingunxantathu, izingxenyekazi zekhompuyutha ezixhumayo (indandatho elengayo emise okuka-U, ipuleti lokulungisa), izibophelelo zesakhiwo, njll.
Inhloso:Ukuthwala ukungezwani okuphelele.Xhuma intambo yaphansi eyinhlanganisela ye-fiber optical kutheminali, ukumelana ne-strain noma umbhoshongo wokuxhuma wekhebula le-optical.
