Nibihe fibre optique ikoreshwa mukubaka imiyoboro yohereza?
Hariho ubwoko butatu bwingenzi: G.652 isanzwe imwe-fibre fibre, G.653 ikwirakwizwa-ihinduranya imwe-fibre and G.655 fibre itari zeru ikwirakwizwa.
G.652 fibre imweifite ikwirakwizwa ryinshi muri C-band 1530 ~ 1565nm na L-band 1565 ~ 1625nm, muri rusange 17 ~ 22psnm • km, iyo igipimo cya sisitemu kigeze kuri 2.5Gbit / s cyangwa kirenga, hasabwa indishyi zo gutatanya, kuri 10Gbit / s Indishyi igiciro cya sisitemu ni kinini, kandi nubwoko busanzwe bwa fibre yashyizwe mumurongo wohereza kuri ubu.
Ikwirakwizwa ryaG.653 ikwirakwiza-fibremuri C-band na L-band muri rusange -1 ～ 3.5psnm • km, hamwe na zeru ikwirakwizwa kuri 1550nm, kandi igipimo cya sisitemu gishobora kugera kuri 20Gbit / s na 40Gbit / s, nuburebure bwumurongo umwe ultra-ndende-intera kwanduza Fibre nziza.Ariko, kubera imiterere ya zeru-itatanya, mugihe DWDM ikoreshwa mukwagura, ingaruka zidafite umurongo zizabaho, biganisha ku kimenyetso cyambukiranya, bikavamo imivumba ine ivanga FWM, bityo DWDM ntabwo ikwiye.
G.655 fibre itari zeru ikwirakwizwa: F.Gutatanya ni bito kandi birinda zeru.Agace ka dispersion ntikumira gusa imiyoboro ine ivanga FWM, irashobora gukoreshwa mugukwirakwiza DWDM, ariko kandi irashobora gufungura sisitemu yihuta.Fibre nshya ya G.655 irashobora kwagura ahantu heza kugeza kuri 1,5 kugeza kuri 2 ya fibre isanzwe, kandi ahantu hanini hashobora kugabanuka ingufu!
