Icyitegererezo:kugoreka-kutumva fibre imwe (G.657A2)
Ubuyobozi bukuru:Kuzuza ibisabwa na ITU-T G.657.A1 / A2 / B2 optique ya fibre optique.
Ibiranga ibicuruzwa:
- Radiyo ntarengwa yo kugonda irashobora kugera kuri 7.5mm, hamwe no kunama neza;
- Bihujwe rwose na G.652 fibre imwe-fibre imwe;
- 1260 ～ 1626nm yohereza umurongo wuzuye;
- Uburyo bwa polarisiyasi ntoya ikwirakwiza yujuje ibyifuzo byihuta kandi byihuta;
- Ikoreshwa mumigozi itandukanye ya optique, harimo insinga ya optique, hamwe na bike byiyongera cyane kuri micro-bending;
- Ifite ibipimo byinshi birwanya umunaniro kugirango ubuzima bwa serivisi bugabanuke kuri radiyo nto.
- Icyitonderwa cyo gusaba: Ikoreshwa kuri insinga ya optique yuburyo butandukanye, ihererekanyabubasha ryuzuye kuri 1260 ~ 1626nm, FTTH yihuta yihuta ya optique, insinga ya optique ifite radiyo ntoya isabwa, insinga ntoya ya optique nibikoresho bya fibre optique, nibisabwa yo gukoresha L-band.
