G.652D Alava opitika tulaga tasi-moega (B1.3)-Vaega B

G.652D Single-mode opitika fiber (B1.3)-Grade B Ata Fa'aalia

Fa'amatalaga Puupuu:

O le maualuga o le vai maualalo e le faʻasalalauina le solo e tasi-mode e talafeagai mo le faʻaogaina o le faʻaogaina o le fusi atoa 1280nm ~ 1625nm, lea e le gata ina faʻatumauina le maualalo o le faʻasalalauina o le 1310nm masani, ae o loʻo i ai foi se gau maualalo i le 1383nm, ma faia ai le E band. (1360nm ~ 1460nm) fa'aoga atoatoa. O le gau ma le faʻasalalauina o le faʻaupuga atoa mai le 1260nm i le 1625nm ua faʻamalosia, ma o le gau o le 1625nm wavelength ua faʻaititia, lea e maua ai punaoa bandwidth mo fesoʻotaiga i tua, MAN ma fesoʻotaʻiga avanoa.

Oloa Fa'ailoga

● O le faʻasinomaga o le pito i lalo o le vai e le faʻasalalau-siitia solo tasi-mode e sili atu nai lo ITU-T fautuaina G.652D ma IEC B1.3 fiber faʻamatalaga faʻapitoa;

● Faʻatinoga lelei tele, e mafai ona faʻamalieina le maualuga o le DWDM ma le tuʻuina atu o manaʻoga o le CWDM;

● sili geometry lapoa, ia mautinoa le ueloina o le leiloa maualalo ma le maualuga o le faʻamaufaʻailoga;

● Low coefficient o le PMD, faʻamalieina le faʻaogaina o le faiga o le mamao mamao ma le maualuga maualuga.

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 opitika e aofia ai: faiga fa'apipi'i fiber e mana'omia ai le gau maualalo ma le bandwidth maualuga, e pei o feso'ota'iga mamao-mamao, laina ogalaau, fafaga fa'aoga, laina tufatufaina ma le TV cable, ma isi, aemaise lava mo le 1383nm band coarse wavelength division multiplexing ( CWDM), mafiafia galu vaevaega multiplexing (DWDM) ma eseese faʻaoga siosiomaga faʻapitoa (faʻataʻitaʻiga Uila-faʻamaonia OPGW opitika uaea, ADSS uaea opitika, ma isi), o le alava opitika e ala i le malamalama faapitoa faʻamalolo mea faʻapipiʻi ma faʻagasologa faʻapipiʻi ma a maeʻa le gaioiga, ina ia o loʻo i ai se faʻatinoga sili atu ona maualuga i mea faʻainisinia ma le maualuga o le vevela o le siosiomaga.
