G.657A1 Pi'o-le ma'ale'ale alava tasi-moega Fa'aalia Ata

Fa'amatalaga Puupuu:

O le oloa faʻaaogaina le faʻaogaina o mea faʻapipiʻi faʻapipiʻi uma, e mafai ona pulea le OH- anotusi o le fiber faʻapipiʻi i se tulaga maualalo, o lea o le oloa o loʻo i ai le maualuga o le attenuation coefficient ma le maualalo o le vai, sili atu le faʻatinoina o felauaiga.O le oloa e mafai ona faʻamautinoaina se laina faʻapipiʻi laʻititi aʻo fetaui atoatoa ma le fesoʻotaʻiga G.652D, o lea e mafai ai e le fiber ona faʻafetaui atoatoa manaʻoga o le FTTH.

Fa'aaogāga o Mea

1. Talafeagai mo ituaiga uma o le fiber optic fausaga uaea: totonugalemu ituaiga faagaau, vaega lima vaivai ituaiga saisaitia, ituaiga auivi, fiber optic fausaga uaea;

2. Fa'aaogāga o fibre optics e aofia ai: fiber optic systems e mana'omia ai le maualalo o le gau ma le maualuga o le bandwidth;E sili ona talafeagai mo MAN uaea malu opitika, tamai afifi opitika masini alava, opitika faimea coupler ma isi talosaga faapitoa;

3. O lenei ituaiga fiber e talafeagai mo O, E, S, C ma L fusi (o lona uiga, mai le 1260 i le 1625nm).O lenei ituaiga o fibre opitika e fetaui lelei ma le fiber G.652D.O faʻamatalaga mo le paʻu o le gau ma le avanoa faʻapipiʻi e sili ona faʻaleleia, ia faʻaleleia uma le fesoʻotaʻiga;

4. E mafai ona lagolagoina le faʻapipiʻiina o le afa-diamita laʻititi ma le faʻaogaina o le fiber optical system i totonu o ofisa o fesoʻotaʻiga ma nofoaga faʻatau i fale nofoia ma fale taʻitasi.
