Tun da OM1 da OM2 fibers ba za su iya tallafawa saurin watsa bayanai na 25Gbps da 40Gbps ba, OM3 da OM4 sune babban zaɓi don filaye masu yawa waɗanda ke goyan bayan 25G, 40G da 100G Ethernet.Koyaya, yayin da buƙatun bandwidth ke ƙaruwa, farashin kebul na fiber optic don tallafawa ƙaurawar saurin Ethernet na gaba yana ƙaruwa kuma yana ƙaruwa.A cikin wannan mahallin, OM5 fiber an haife shi don faɗaɗa fa'idodin fiber multimode a cikin cibiyar bayanai.
Multimode fiber optic USB model:
OM3 shine 50um core diamita multimode fiber ingantacce ta 850nm Laser.A cikin 10Gb/s Ethernet ta amfani da 850nm VCSEL, nisan watsa fiber zai iya kaiwa 300m;OM4 shine ingantaccen sigar OM3, OM4 multimode fiber yana inganta OM3 multimode fiber Saboda yanayin jinkirin yanayin bambance-bambance (DMD) da aka haifar yayin watsawa mai sauri, nisan watsawa ya inganta sosai, kuma nisan watsa fiber na gani zai iya kaiwa 550m.
Babban bambanci tsakanin su shine cewa a ƙarƙashin 4700MHz-km, EMB na fiber OM4 an ƙayyade shi kawai a matsayin 850 nm, yayin da aka ƙayyade darajar OM5 a matsayin 850 nm da 953 nm, kuma darajar a 850 nm ya fi OM4 girma.Don haka, fiber OM5 yana ba masu amfani da nisa mai tsayi da ƙarin zaɓuɓɓukan fiber.Bugu da kari, TIA ta sanya lemun tsami koren a matsayin launi na jaket na USB na OM5, yayin da OM4 shine jaket na ruwa.OM4 an tsara shi don 10Gb / s, 40Gb / s da 100Gb / s watsawa, amma OM5 an tsara shi don watsawa na 40Gb / s da 100Gb / s, wanda zai iya rage adadin filaye na gani don watsawa mai sauri.
Bugu da kari, OM5 na iya tallafawa tashoshi na SWDM guda hudu, kowannensu yana dauke da bayanan 25G, kuma yana amfani da filaye na gani na multimode guda biyu don samar da 100G Ethernet.Bugu da ƙari, yana da cikakkiyar jituwa tare da zaruruwan OM3 da OM4.Ana iya amfani da OM5 don shigarwa a wurare daban-daban na kamfanoni a duniya, daga harabar harabar gine-gine zuwa cibiyoyin bayanai.A takaice dai, fiber OM5 ya fi OM4 kyau ta fuskar watsa nisa, gudu da farashi.
Bayanin ƙirar ƙirar fiber na gani na gaba ɗaya: Ɗauki nau'i-nau'i mai nau'i-nau'i huɗu a matsayin misali, (4A1b shine 62.5/125µm, 4A1 shine 50/125µm).
