Fur Whats App
Nooca:
Laaci Dareemka Hal-qaab ee Fiber indhaha ah (G.657.B3)
Heerka:
Fiberku wuxuu u hoggaansamaa ama ka badan yahay tilmaamaha farsamada ee ITU-T G.657.A1/A2/B2/B3.
Tilmaam:
7.5mm qalooci ugu yar, hanti ka-hortagga foorarsiga;
Si buuxda ula jaan qaada G.652 fiber hal-hab ah.Qayb buuxda (1260 ~ 1626nm) gudbinta;
PMD hoose oo loogu talagalay gudbinta heerka-yar ee sare iyo masaafada dheer.Attenuation-ka-laabashada yar-yar oo aad u hooseeya, oo lagu dabaqi karo dhammaan noocyada fiilooyinka indhaha oo ay ku jiraan xargaha;
Qiyaasta sare ee ka-hortagga daalka waxay hubisaa nolosha adeegga iyada oo hoos timaadda qaloocinta yar yar.
Codsiga:
Dhammaan dhismayaasha fiilooyinka, 1260 ~ 1626nm gudbinta band buuxa, FTTH xawaaraha sare ee dariiqa indhaha, fiilada indhaha ee radius yar yar, fiilada fiber-ka-yar ee cabbirka iyo qalabka.

Warshada Cable ee indhaha
2004tii, GL FIBER waxay aas aastay warshadan si ay u soo saarto wax soo saarka xadhkaha indhaha, oo inta badan soo saarta xargaha fiilada, xadhiga indhaha 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 isbar-bar 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.
