Ikhebula le-FTTH Ngaphandle
Ikhebuli yokudonsa yangaphandle ye-FTTH(GJYXFCH/GJYXCH) ibizwa nangokuthi ikhebula le-butterfly drop Optical elizisekelayo elinentambo yovemvane yasendlini kanye nelungu elinamandla elengeziwe elingu-1-12 fiber cores.FTTH outdoor drop cable(GJYXFCH/GJYXCH) ibizwa nangokuthi ukuzisekela. butterfly drop Optical cable ehlanganisa ikhebula uvemvane yasendlini kanye nelungu lamandla engeziwe ezinhlangothini zombili.I-fiber count ingaba yi-fiber cores eyi-1-12.
Isici I-1.Special low-band-sensitivity fiber inikeza i-bondwidth ephezulu kanye nempahla yokudlulisa ukuxhumana okuhle kakhulu; 2.Amalungu amabili aqinile ahambisanayo aqinisekisa ukusebenza kahle kokumelana nokuchoboza ukuvikela i-fiber; 3.Isakhiwo esilula.isisindo esincane nokusebenza okuphezulu; 4.Ukwakheka komtshingo okunoveli, ukuhlubula kalula nokuhlanganisa, kwenza ukufakwa nokugcinwa kube lula; I-5.Single steel wire njengelungu elingeziwe lamandla liqinisekisa ukusebenza okuhle kwamandla aqinile. I-Fiber Parameters: Amapharamitha ekhebula: Izimpawu zemishini nezemvelo:
