Intshayelelo yeMveliso
I-Optical Fiber yenziwe ngemisonto yeglasi okanye yeplastiki ehambisa idatha njengeepulse zokukhanya, inika isantya esiphezulu kakhulu sokudlulisa idatha. Ingathwala ulwazi oluninzi kumgama omde ngaphandle kokulahleka okukhulu kwesiginali. Ngokungafaniyo neentambo zobhedu zemveli, i-Optical Fiber ayithintelwa kukuphazamiseka kwe-electromagnetic kunye nokuphazamiseka kwe-radiofrequency, okuqinisekisa isiginali ecocekileyo nethembekileyo. Olu mgangatho lwenza i-Optical Fiber ibe lukhetho olufanelekileyo kunxibelelwano kunye neenethiwekhi zokuhamba ixesha elide.
Sinikezela ngeendidi ezahlukeneyo zeemveliso zefayibha ye-optical, kuquka i-G.652.D, i-G.657.A1, i-G.657.A2, nezinye ezininzi ukuze zihlangabezane neemfuno zakho ezithile.
iimpawu
I-fiber ye-optical esiyinikezileyo ineempawu ezilandelayo:
1) Ukukhetha okuguquguqukayo kweengubo ezahlukeneyo ukuhlangabezana neemfuno zezihlandlo ezahlukeneyo zesicelo.
2) I-coefficient encinci yokusasazwa kwemo ye-polarization, efanelekileyo ekudlulisweni kwesantya esiphezulu.
3) Ukumelana nokudinwa okunamandla kakhulu, okufanelekileyo ukusetyenziswa kwiindawo ezahlukeneyo.
Isicelo
Isetyenziswa kakhulu kwiintlobo ngeentlobo zentambo ye-optical ukudlala indima yonxibelelwano.
