G.657A1 Kwunama-kutumva kimwe-fibre

G.657A1 Kwunama-kutumva-uburyo bumwe bwa fibre Yerekanwe

Ibisobanuro bigufi:

Igicuruzwa gikoresha ubuhanga bugezweho bwa sintetike ya fibre yakozwe mbere yubuhanga bwo gukora inkoni, ishobora kugenzura OH- ibirimo inkoni ya fibre yakozwe mbere kurwego rwo hasi cyane, bityo ibicuruzwa bifite coefficient nziza ya attenuation hamwe nimpinga y'amazi make, imikorere myiza yo kohereza. Igicuruzwa kirashobora kwemeza radiyo ntoya mugihe ihuye neza numuyoboro wa G.652D, bityo fibre irashobora kuzuza byimazeyo ibyifuzo bya FTTH.

2. Gukoresha fibre optique harimo: sisitemu ya fibre optique isaba igihombo gito numuyoboro mwinshi; Birakwiriye cyane cyane kubikoresho bya MAN byoroshye optique, pake ntoya ya optique ya fibre optique, fibre optique hamwe nibindi bidasanzwe;

3. Ubu bwoko bwa fibre bubereye imirongo ya O, E, S, C na L (ni ukuvuga kuva 1260 kugeza 1625nm). Ubu bwoko bwa fibre optique burahuye neza na fibre ya G.652D. Ibisobanuro byo guhomba igihombo n'umwanya muto byatejwe imbere cyane, byombi kunoza umurongo;
