ITU-G.657A2 Hewari Piko Fiber
Tuwhera Whats App
Momo:
Whakapiko i te Waea Matapihi Aratau-kotahi (G.657.A2)
Paerewa:
Ko te muka e tutuki ana, neke atu ranei i nga waahanga hangarau i roto i te ITU-T G.657.A1/A2/B2.
Āhuahira:
Putoro piko iti 7.5mm, tino pai rawa atu ki te whakapiko;
Tino hototahi ki G.652 muka aratau kotahi. Ko te roopu katoa (1260~1626nm) te tuku;
He iti te PMD mo te tere moka teitei me te tuku tawhiti. He iti rawa te whakaheke moroiti-piko, e tika ana mo nga momo taura whatu katoa tae atu ki nga riipene;
Ko te tawhā anti-ngenge teitei e whakarite ana i te ora ratonga i raro i te radius piko iti.
Taupānga:
Ko nga hanganga taura katoa, 1260~1626nm te tuku roopu katoa, te ararere whatu tere tere FTTH, te taura whatu i roto i te radius piko iti, iti-rahi taura muka whatu me te taputapu.

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.
