Warshada Cable ee indhaha
2004tii, GL FIBER waxay aas aastay warshada soo saarta wax soo saarka xadhkaha indhaha (optical cable) oo inta badan soo saarta xargaha fiilada lagu shubo, xadhkaha indhaha ee dibadda, iwm.
GL Fiber hadda waxay leedahay 18 qaybood oo ah qalabka midabaynta, 10 qaybood oo ah qalabka daahan caagga ah ee labaad, 15 qaybood oo ah qalabka maroojin ee lakabka SZ, 16 qaybood oo ah qalabka wax lagu dhejiyo, 8 qaybood oo ah qalabka wax soo saarka fiilada ee FTTH, 20 qaybood oo ah qalabka fiilada indhaha ee OPGW, iyo 1 qalab isbarbar socda iyo qalab kale oo badan oo wax soo saarka ah. Waqtigan xaadirka ah, awoodda wax-soo-saarka fiilooyinka indhaha ee sannadlaha ah waxay gaartaa 12 milyan-core-km (celceliska awoodda wax-soo-saarka maalinlaha ah ee 45,000 core km iyo noocyada fiilooyinka waxay gaari karaan 1,500 km). Warshadahayadu waxay soo saari karaan noocyo kala duwan oo ah fiilooyinka gudaha iyo dibaddaba (sida ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, fiilada-yar ee hawada lagu afuufay, iwm.). awoodda wax-soo-saarka maalinlaha ah ee fiilooyinka caadiga ah waxay gaari karaan 1500KM / maalin, awoodda wax-soo-saarka maalinlaha ah ee fiilada dhibcaha waxay gaari kartaa max. 1200km/maalintii, iyo awoodda wax soo saarka maalinlaha ah ee OPGW waxay gaari kartaa 200KM/maalintii.
