Ikhebula le-FTTH langaphakathi
Ikhebula le-FTTH elitholwa kalula ngefayibha kanye nokufakwa okulula, ikhebula le-FTTH lingaxhunywa ngqo emakhaya.
Ifanele ukuxhuma nemishini yokuxhumana, futhi isetshenziswa njengekhebula lokungena esakhiweni ohlelweni lokusabalalisa izakhiwo. Imicu ye-optical ibekwe phakathi nendawo futhi amalungu amabili okuqina e-Fiber Reinforce Plastic (FRP) ahambisanayo abekwa ezinhlangothini ezimbili. Ekugcineni, ikhebula ligcwaliswa nge-LSZH sheath.
Izici: 1. Ithambile futhi iyagobeka, kulula ukuyibeka kanye nokulungisa. 2. Ububanzi obuncane, Isisindo esincane, kanye nokusebenza kahle kakhulu. 3. Ipulasitiki eqiniswe ngefayibha njengelungu lamandla iqinisekisa ukusebenza okuhle kakhulu kokulwa ne-electromagnetic. 4. Ukuvikelwa kwemvelo- Intuthu ephansi, i-halogen engenawo kanye ne-flame retardant sheath. 5. Ukwakheka okuhle kokumelana namanzi.
