Amasignali omsakazo ayindlela ebalulekile yokuxhumana yezinhlelo zokusebenza ezihlukahlukene, njengokusakaza, izinsizakalo eziphuthumayo, nokuzulazula.Kodwa-ke, ukulahlekelwa kwesignali kungenzeka ngenxa yezici ezihlukahlukene, okuholela ekwamukeleni okuncane noma ukungabikho nhlobo.Ezinye izinkinga ezivamile ezingase zithinte isignali yakho yomsakazo zihlanganisa ukuvinjelwa ngokomzimba, ukuphazamiseka kukazibuthe kagesi, ibanga ukusuka kumthombo, nezinkinga ze-antenna.Kubalulekile ukukhomba imbangela yokulahleka kwesignali ukuze kubhekwane nenkinga futhi kuqinisekiswe ukuxhumana okuthembekile.
Izimbangela ezivame kakhulu zokwehluleka kwe-fiber:
• Ukuphuka kwefiber ngenxa yokucindezeleka ngokomzimba noma ukugoba ngokweqile
• Amandla okudlulisa anganele
• Ukulahleka kwesignali okweqile ngenxa yezikhonkwane zekhebula ezinde
• Izixhumi ezingcolile zingabangela ukulahlekelwa kwesignali ngokweqile
• Ukulahleka kwesignali ngokweqile ngenxa yokungaphumeleli kwesixhumi noma isixhumi
• Ukulahleka kwesignali ngokweqile ngenxa yezixhumi noma izixhumi eziningi kakhulu
• Ukuxhumeka okungalungile kwefayibha kuphaneli yokunamathisela noma ithreyi le-splice
Ngokuvamile, uma uxhumano kwehluleka ngokuphelele, kungenxa yokuthi ikhebula liphukile.Kodwa-ke, uma ukuxhumana kuphazamiseka, kunezizathu ezimbalwa ezingenzeka:
• Ukunciphisa ikhebula kungase kube phezulu kakhulu ngenxa yezixhumi zekhwalithi engeyinhle noma izixhumi eziningi kakhulu.
• Uthuli, izigxivizo zeminwe, imihuzuko, nomswakama kungangcolisa izixhumi.
• Amandla okudlulisela aphansi.
• Ukuxhumana okungalungile ekhabetheni lezintambo.
