Intshayelelo yeMveliso
IFayibha ye-Optical yenziwe ngeglasi okanye imisonto yeplastiki esasaza idatha njengemibhobho yokukhanya, inikezela ngesantya esiphezulu kakhulu sothumelo lwedatha. Inokuthwala ulwazi oluninzi kumgama omde kunye nelahleko encinci yomqondiso. Ngokungafaniyo neentambo zobhedu zemveli, i-Optical Fiber ayinakuchaphazeleka kuphazamiseko lwe-electromagnetic kunye nokuphazamiseka kweradiofrequency, iqinisekisa uphawu olucocekileyo noluthembekileyo. Lo mgangatho wenza i-Optical Fiber ibe lolona khetho lufanelekileyo kunxibelelwano lomnxeba kunye nothungelwano olude.
Sibonelela ngeendidi ezahlukeneyo zeemveliso zefiber optical, kubandakanywa i-G.652.D, G.657.A1, G.657.A2, kunye nezinye ezininzi ukukhawulelana neemfuno zakho ezithile.
iimpawu
Ifiber optical esiyinike yona inezi mpawu zilandelayo:
1) Ukukhetha okuguquguqukayo kweengubo ezahlukeneyo zokukhawulelana neemfuno zezihlandlo ezahlukeneyo zesicelo.
I-2)I-polarization encinci ye-coefficient ye-dispersion coefficient, ifanelekile kwi-high-speed transmission.
3) Ukumelana nokudinwa okuguquguqukayo okuphezulu, kukulungele ukusetyenziswa kwiindawo ezahlukeneyo.
Isicelo
Ikakhulu isetyenziswa kwiindidi ezahlukeneyo zentambo ye-optical ukudlala indima yonxibelelwano.

Ukupakishwa
I-G.652D i-optical fiber ithathwa phezulu kwi-spool yeplastiki, ifakwe kwibhokisi, kwaye emva koko ifakwe kwi-pallet kwaye ilungiswe ngefilimu yokusonga.
Iispools zeplastiki zifumaneka ngobukhulu obuthathu.
1) 25.2km/spool
2) 48.6km/spool
3) 50.4km/spool
Ugcino
