Nyob rau xyoo 2004, GL FIBER tau tsim lub Hoobkas los tsim cov khoom siv kho qhov muag, feem ntau tsim cov hlua khi, sab nraum zoov kho qhov muag cable, thiab lwm yam.
GL Fiber tam sim no muaj 18 txheej ntawm cov khoom siv xim, 10 txheej txheej txheej txheej txheej txheej txheej, 15 txheej ntawm SZ txheej twisting equipments, 16 txheej ntawm sheathing equipments, 8 teeb ntawm FTTH poob cable ntau lawm equipments, 20 teeb ntawm OPGW optical cable equipments, thiab 1 paralleling khoom Thiab ntau lwm yam khoom pab khoom siv.Tam sim no, txhua xyoo muaj peev xwm ntawm optical cables ncav cuag 12 lab core-km (nruab nrab txhua hnub muaj peev xwm ntawm 45,000 core km thiab hom cables tuaj yeem ncav cuag 1,500 km).Peb cov chaw tsim khoom tuaj yeem tsim ntau hom kab hluav taws xob sab hauv tsev thiab sab nraum zoov (xws li ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, cua tshuab micro-cable, thiab lwm yam).lub peev xwm tsim khoom txhua hnub ntawm cov kab hluav taws xob ntau tuaj yeem ncav cuag 1500KM / hnub, lub peev xwm tsim tawm txhua hnub ntawm kev poob cable tuaj yeem ncav cuag max.1200km / hnub, thiab txhua hnub muaj peev xwm ntawm OPGW tuaj yeem ncav cuag 200KM / hnub.
