wheketere taura whatu
I roto i te 2004, GL FIBER whakapumautia te wheketere ki te whakaputa hua taura whatu, te nuinga whakaputa taura maturuturu, taura whatu waho, etc.
GL Fiber inaianei kua 18 nga huinga taputapu tae, 10 nga huinga taputapu whakakikorua kirihou tuarua, 15 nga huinga o nga taputapu whakakorikori paparanga SZ, 16 nga huinga taputapu whakakakahu, e 8 nga huinga taputapu hanga taura FTTH maturuturu, 20 huinga o nga taputapu taura whatu OPGW, me 1 taputapu whakarara Me te maha atu o nga taputapu awhina whakaputa. I tenei wa, ka eke ki te 12 miriona matua-km te kaha whakaputa a-tau o nga taura whatu (te kaha o ia ra o te 45,000 km matua me nga momo taura ka tae ki te 1,500 km). Ka taea e o maatau wheketere te whakaputa momo momo taura o roto, o waho hoki (pēnei i te ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, taura moroiti-rangi, etc.). Ko te kaha o ia ra o nga taura noa ka tae ki te 1500KM / ra, ka taea e te whakaputanga o ia ra o te taura maturuturu te eke ki te max. 1200km/ra, a ko te kaha whakaputa o ia ra o OPGW ka eke ki te 200KM ia ra.
