Fa'ata'ita'iga fa'amatalaga:filo e tasi-moega le maaleale (G.657A2)
Tulaga fa'atonu:Faʻafeiloaʻi manaʻoga o le ITU-T G.657.A1 / A2 / B2 faʻamatalaga faʻapitoa faʻapitoa.
Fa'ailoga oloa:
- Ole la'ititi la'ititi ole pi'o e mafai ona o'o ile 7.5mm, fa'atasi ai ma le fa'ato'a lelei o le punou;
- E fetaui lelei ma le G.652 fa'aoga tasi;
- 1260～1626nm fa'aliliuga fa'asolo atoa;
- O le fa'asalalauina o faiga fa'avae maualalo e fetaui ma mana'oga o le televave ma le mamao mamao;
- Fa'aoga i uaea mata'utia eseese, e aofia ai uaea opitika lipine, fa'atasi ai ma le fa'aitiitia o le fa'aopoopoina o le micro-bending;
- O loʻo i ai tulaga maualuga e faʻasaʻo ai le vaivai e faʻamautinoa ai le ola tautua i lalo o le laina faʻapipiʻi laʻititi.
- Faʻamatalaga Faʻamatalaga: O loʻo faʻaogaina i laina faʻapipiʻi o fausaga eseese, faʻasalalauga atoa-galu i le 1260 ~ 1626nm, FTTH faʻavavevave faʻataʻitaʻiga opitika, uaea faʻapipiʻi faʻatasi ai ma mea e manaʻomia e laʻititi laʻititi, laʻititi laʻititi laʻititi ma masini fiber optical, ma manaʻoga. o le faʻaaogaina o le L-band.
