Kubera ko fibre ya OM1 na OM2 idashobora gushyigikira umuvuduko wo kohereza amakuru ya 25Gbps na 40Gbps, OM3 na OM4 nizo guhitamo nyamukuru kuri fibre fibre nyinshi zishyigikira 25G, 40G na 100G Ethernet.Nyamara, uko ibisabwa byihuta byiyongera, igiciro cyinsinga za fibre optique kugirango gishyigikire ibisekuruza bizaza Ethernet yihuta nayo igenda yiyongera.Ni muri urwo rwego, fibre ya OM5 yavutse kugirango yongere ibyiza bya fibre fibre muri data center.
Multimode fibre optique ya kabili:
OM3 ni 50um yibanze ya diameter multimode fibre yatunganijwe neza na 850nm laser.Muri 10Gb / s Ethernet ukoresheje 850nm VCSEL, intera yohereza fibre irashobora kugera kuri 300m;OM4 ni verisiyo yazamuye ya OM3, fibre ya OM4 ya optime itunganya fibre ya OM3 Multimode Bitewe nuburyo butandukanye bwo gutinda (DMD) byakozwe mugihe cyihuta cyihuta, intera yoherejwe yateye imbere cyane, kandi intera yohereza fibre optique irashobora kugera kuri 550m.
Itandukaniro ryingenzi hagati yabo nuko munsi ya 4700MHz-km, EMB ya fibre ya OM4 isobanurwa gusa nka 850 nm, mugihe OM5 EMB agaciro kayo kangana na 850 nm na 953 nm, naho agaciro ka 850 nm karenze OM4.Kubwibyo, OM5 fibre itanga abakoresha intera ndende nuburyo bwinshi bwa fibre.Byongeye kandi, TIA yashyizeho icyatsi kibisi nkibara ryemewe rya kabili ya OM5, naho OM4 ni ikoti ryamazi.OM4 yagenewe 10Gb / s, 40Gb / s na 100Gb / s yohereza, ariko OM5 yagenewe kohereza 40Gb / s na 100Gb / s, bishobora kugabanya umubare wa fibre optique yo kohereza byihuse.
Mubyongeyeho, OM5 irashobora gushyigikira imiyoboro ine ya SWDM, imwe murimwe itwara amakuru ya 25G, kandi ikoresha fibre optique ya fibre optique kugirango itange 100G Ethernet.Mubyongeyeho, irahujwe rwose na fibre ya OM3 na OM4.OM5 irashobora gukoreshwa mugushiraho muburyo butandukanye bwibigo bitandukanye kwisi, kuva mumashuri kugeza inyubako kugeza kubigo byamakuru.Muri make, fibre ya OM5 iruta OM4 ukurikije intera yoherejwe, umuvuduko nigiciro.
Muri rusange fibre optique ya fibre optique yerekana ibisobanuro: Fata intangarugero enye-nyinshi-urugero nkurugero, (4A1b ni 62.5 / 125µm, 4A1 ni 50 / 125µm).
