O feso'ota'iga alava mata e mana'omia le malamalama e fai ma fa'amatalaga fa'amatalaga e feso'ota'i ai.E mafai ona fa'asalalauina e ala i le fiber core.Peitaʻi, e lē o ave uma o le malamalama e talafeagai mo fesootaʻiga.O le gau o le felauaiga e fesuisuia'i i fusi galu eseese o le malamalama.Mo le ausiaina o le itiiti ifo o le gau ma le lelei, o saienitisi o loʻo sailia pea le malamalama sili ona talafeagai.
- 850nm Galue fusi
I le amataga o le 1980s, na amata suʻesuʻe ai e saienitisi le tekinolosi o fesoʻotaʻiga fiber opitika i se auala aoga.O le tele-mode fiber o le mea na masani ona latou suʻesuʻeina.Fa'atasi ai ma alava lapopo'a, alava muti-mode e mafai ona iloa se tasi fiber felauaiga mo muti-mode moli.850nm wavelength malamalama o le tasi lea e faʻaaogaina muamua.
- E Galufuga
I le amataga o le 1990s, na amata ona faʻaaogaina lautele le fiber faʻaoga tasi.
Ata 1
Sa iloa e saienitisi o le 1260nm ~ 1360nm waveband moli e mafai ona ausia le itiiti ifo o le faʻalavelave faʻailoga ma le gau o le faʻasalalauga e mafua mai i le taʻape e ala i suʻega.Faatasi ai ma tofotofoga ma mea sese, na iloa ai e saienitisi o le moli ma le 1260nm ~ 1625nm o loʻo i ai foi i le pito sili ona leiloa ma o le malamalama sili ona talafeagai mo le faʻasalalauina o fiber.
1260nm ~ 1625nm waveband malamalama ua vaevaeina i lima-O waveband, E waveband, S waveband, C waveband ma L waveband.
Ata 2
Sa maua foi e saienitisi le sootaga i le va o le gau ma le umi o galu.O lo'o fa'aalia e fa'apea.
Ata 3
O le fa'a'ili masani fa'aaogaina o le C waveband ((1530nm~1565nm), o lo'o tu mo le "masani".E mafai e le C band ona maua le itiiti ifo o le gau o le felauaiga lea e masani ona faʻaaogaina i le MAN, mamao mamao, ultra long distance, submarine optical cable systems and WDM system.
- L Galulue (1565nm~1625nm)
L e tu mo le "umi-umi-umi".L waveband e mafai ona ausia le gau lona lua sili ona maualalo ma o se tasi foi o filifiliga autu mo alamanuia.Afai e le mafai e C waveband ona fa'afetaui mana'oga o le bandwidth, e masani ona ave e tagata le L waveband e fai ma fa'atasi.
- S Waveband(1460nm~1530nm)
S o lo'o fa'atusa mo le "pu'upu'u galu umi".A o'o mai i le gau o alava, e maualuga atu nai lo le fusi o galu O.E masani ona faʻaaogaina i lalo ole galu o le PON.
- E Galue fusi
O le fusi galu e sili ona taatele i ituaiga e lima o fusi galu.E fa'atusa mo le "fa'alautele". E pei ona fa'aalia mai le ata 3, e mafai ona va'aia se fa'aputuga i luga o le fusi galu E.E mafua ona o le mitiia e le OH- e oʻo atu ai i le tele o faʻasalalauga gau, lea e taʻua foi o le vai maualuga.
I tua i aso tuai, ona o le utiuti o tekinolosi, na faʻafefiloi ai le vai i totonu o tioata fiber opitika lea na taʻitaʻia ai le tele o faʻasalalauga i le E waveband ma e le mafai ona galue masani.Mulimuli ane, na fa'atupuina e tagata le fa'atekonolosi fa'amama i le gaosiga o tioata, talu mai lena taimi, o le gau o le gau i le E waveband na maualalo ifo nai lo O waveband.Ae ui i lea, o le gau o le felauaiga na tupu i luga o le E waveband i luga o le fiber optical cable lea na faʻamatalaina o loʻo iai pea tapulaʻa mo E waveband o loʻo faʻaogaina i le fiber optical communication.
- U Waveband(fa'aili maualuga-umi-umi, 1625-1675 nm)
Se'i vagana ai nei waveband lea na ta'ua, U waveband e fa'aaogaina lautele, aemaise lava i luga ole mata'ituina o feso'otaiga.
