Optical Fiber
Folasaga o oloa
O le Optical Fiber e gaosia mai tioata po'o filo palasitika e tu'uina atu fa'amatalaga e pei o pulupulu o le malamalama, e ofoina atu le maualuga tele o fa'asalalauga fa'amatalaga. E mafai ona ave le tele o faʻamatalaga i luga o mamao mamao ma faʻaitiitia faʻailoga leiloa. E le pei o uaea apamemea masani, Optical Fiber e le mafai ona faʻalavelave i le electromagnetic faʻalavelave ma faʻalavelave leitio, faʻamaonia se faʻailoga mama ma faʻatuatuaina. O lenei tulaga lelei ua avea ai le Optical Fiber ma filifiliga lelei mo feso'ota'iga ma feso'ota'iga umi.
Matou te tuʻuina atu le tele o ituaiga o oloa fiber opitika, e aofia ai le G.652.D, G.657.A1, G.657.A2, ma le tele o isi mea e faʻatatau i ou manaʻoga patino.
uiga
O le fiber optical na matou tuʻuina atu e iai uiga nei:
1) Filifiliga fetuutuunai o coatings eseese e fetaui ma manaʻoga o taimi faʻaoga eseese.
2) Laiti polarization faiga fa'asalalau fa'atasi, talafeagai mo fa'asalalauga maualuga-saosaoa.
3) Teteʻe malosi malosi vaivai, talafeagai mo le faʻaaogaina i siosiomaga eseese.
Fa'atatauga
E masani ona faʻaaogaina i ituaiga eseese o cable optical e taʻalo ai le matafaioi o fesoʻotaʻiga.

2) 48.6km/spool
3) 50.4km/spool
Teuina
1) E tatau ona teuina le oloa i totonu o se faleteuoloa mama, tumama, mago ma faʻafefe.
2) O le oloa e le tatau ona fa'aputu fa'atasi ma mea e mu ma e le tatau ona latalata i fa'apogai afi.
3) O le oloa e tatau ona aloese mai le susulu o le la ma le timu.
4) E tatau ona faʻapipiʻi atoatoa le oloa e aloese ai mai le susu ma le filogia.
5) E tatau ona puipuia le oloa mai le mamafa mamafa ma isi faʻaleagaina faʻainisinia i le taimi o le teuina.
