Ukukhethwa kweentambo ze-optical akusekelwe kuphela kwinani kunye nohlobo lweentambo ze-optical, kodwa nakwisigqubuthelo sangaphandle sentambo ye-optical ngokwendawo esetyenziswa kuyo intambo ye-optical.
1) Xa intambo ye-optical yangaphandle igqunywe ngqo, kufuneka kukhethwe intambo ye-optical ekhuselweyo. Kwiindawo eziphakamileyo, intambo ye-optical ene-plastic outer sheath emnyama kunye neembambo ezimbini okanye ngaphezulu zokuqinisa zingasetyenziswa.
2) Xa kukhethwa iintambo ze-fiber optic eziza kusetyenziswa kwizakhiwo, kufuneka kuqwalaselwe iimpawu zazo ezithintela umlilo, ezingenabungozi, kunye nezingatshayiyo. Ngokubanzi, uhlobo oluthintela umlilo kodwa olungenabungozi (iPlenum) lungasetyenziswa kwi-conduit okanye umoya ophoqelekileyo, kwaye uhlobo oluthintela umlilo, olungenabungozi, kunye nolungenabungozi (iRiser) kufuneka lusetyenziswe kwindawo evezwe kuyo.
3) Xa ufaka iingcingo ngokuthe nkqo kwisakhiwo, ungakhetha iiNtambo zoSasazo; xa zibekwe ngokuthe tye, ungakhetha iiNtambo zoKwaphuka.
4) Ukuba umgama wokudlulisela ungaphantsi kwe-2 km, ungakhetha intambo ye-multimode optical. Ukuba idlula i-2 km, ungasebenzisa i-repeater okanye ukhethe intambo ye-single-mode optical.
