Ubushinwa bwa mbere bwa mbere bwa fibre optique itanga umuyaga, GL ifite uburambe bwimyaka irenga 17, Uyu munsi, tuzashyiraho umugozi udasanzwe wa fibre optique SFU (Igice cyiza cya fibre ).
Igice cya Smooth Fiber Unit (SFU) kigizwe numurongo wa radiyo ntoya yunamye, nta fibre yamazi G.657.A1 fibre, ikikijwe nigice cyumye cya acrylate kandi ikarindwa na poliethylene yoroheje yoroheje, kugirango ikoreshwe murusobe rwinjira.Kwinjiza: guhuha muri microducts ya 3.5mm.cyangwa 4.0mm.(imbere ya diameter).
