Ituaiga:
Puno'u le Ma'ale'ale Fa'a-Taitasi Fiber Optical (G.657.B3)
Tulaga masani:
O le fiber e tausisia pe sili atu i faʻamatalaga faʻapitoa i le ITU-T G.657.A1/A2/B2/B3.
Vaega:
La'ititi la'ititi o le pi'o 7.5mm, sili atu mea e tete'e punou;
E fetaui lelei ma le G.652 fa'alava fa'asolo tasi.Fa'aili atoa (1260~1626nm) fa'asalalauga;
PMD maualalo mo le maualuga o le bit-rate ma le mamao mamao.E matua'i maualalo le fa'ato'ilaloina o le micro-bending attenuation, e fa'atatau mo ituaiga uma uaea opitika e aofia ai lipine;
O le maualuga o le anti-fatigue parameter e mautinoa ai le ola tautua i lalo o le laina faʻapipiʻi laʻititi.
Talosaga:
Fausia uma uaea, 1260~1626nm fa'asalalau fa'aili atoa, FTTH fa'avavevave fa'ata'ita'i, uaea fa'apipi'i i le fa'ata'amilo la'ititi la'ititi, la'ititi la'ititi uaea alava ma masini.
Tusi lau savali iinei ma lafo mai ia i matou

Falegaosi Uaea Optical
I le 2004, na faʻatūina ai e le GL FIBER le fale gaosi oloa e gaosia ai oloa faʻapipiʻi, aemaise lava le gaosia o le uaea pa'ū, uaea mata i fafo, ma isi.
GL Fiber ua i ai nei 18 seti o meafaigaluega valivali, 10 seti o meafaigaluega faʻapipiʻi palasitika lona lua, 15 seti o SZ layer mimilo meafaigaluega, 16 seti o sheathing meafaigaluega, 8 seti o FTTH pa'u uaea gaosiga meafaigaluega, 20 seti o OPGW opitika meafaigaluega uaea, ma 1 meafaigaluega tutusa ma le tele o isi gaosiga o meafaigaluega fesoasoani.I le taimi nei, o le gaosiga faʻaletausaga o uaea mataʻutia e oʻo atu i le 12 miliona autu-km (o le gaosiga o aso taʻitasi o le 45,000 km matua ma ituaiga o uaea e mafai ona oʻo i le 1,500 km).E mafai e a matou fale gaosi oloa ona gaosia ituaiga eseese o uaea i totonu ma fafo (e pei o le ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, micro-cable ea, ma isi).e mafai ona oʻo i le 1500KM / aso le gaosiga o aso taʻitasi o laina masani, o le gaosiga o aso taʻitasi o le pa'ū uaea e mafai ona oʻo i le maualuga.1200km / aso, ma le gafatia o le gaosiga o aso uma o OPGW e mafai ona oʻo atu i le 200KM / aso.
