Popeza ma fiber a OM1 ndi OM2 sangathe kuthandizira kuthamanga kwa deta ya 25Gbps ndi 40Gbps, OM3 ndi OM4 ndizo zosankha zazikulu za multimode fibers zomwe zimathandizira 25G, 40G ndi 100G Ethernet.Komabe, pamene zofunikira za bandwidth zikuchulukirachulukira, mtengo wa zingwe za fiber optic zothandizira kusuntha kwa liwiro la Ethernet m'badwo ukukulanso.M'nkhaniyi, OM5 fiber idabadwa kuti ikulitse ubwino wa multimode fiber mu data center.
Multimode fiber optic cable model:
OM3 ndi 50um core diameter multimode fiber wokometsedwa ndi 850nm laser.Mu 10Gb / s Ethernet pogwiritsa ntchito 850nm VCSEL, mtunda wotumizira fiber ukhoza kufika 300m;OM4 ndi mtundu wosinthidwa wa OM3, OM4 multimode fiber imakulitsa OM3 multimode CHIKWANGWANI Chifukwa cha kuchedwa kwamitundu yosiyanasiyana (DMD) komwe kumapangidwa panthawi yotumizirana mwachangu, mtunda wotumizira wasinthidwa kwambiri, ndipo mtunda wotumizira ma fiber optical amatha kufikira 550m.
Kusiyana kwakukulu pakati pawo ndikuti pansi pa 4700MHz-km, EMB ya OM4 fiber imatchulidwa kuti 850 nm, pamene mtengo wa OM5 EMB umatchulidwa kuti 850 nm ndi 953 nm, ndipo mtengo wa 850 nm ndi waukulu kuposa OM4.Chifukwa chake, CHIKWANGWANI cha OM5 chimapatsa ogwiritsa ntchito mtunda wautali komanso zosankha zambiri za fiber.Kuphatikiza apo, TIA yasankha laimu wobiriwira ngati mtundu wa jekete yovomerezeka ya OM5, pomwe OM4 ndi jekete lamadzi.OM4 imapangidwira 10Gb / s, 40Gb / s ndi 100Gb / s kutumiza, koma OM5 imapangidwira 40Gb / s ndi 100Gb / s kutumiza, zomwe zingathe kuchepetsa chiwerengero cha optical fibers othamanga kwambiri.
Kuonjezera apo, OM5 ikhoza kuthandizira njira zinayi za SWDM, iliyonse yomwe imanyamula deta ya 25G, ndipo imagwiritsa ntchito ma multimode optical fibers kuti apereke 100G Ethernet.Kuphatikiza apo, imagwirizana kwathunthu ndi ulusi wa OM3 ndi OM4.OM5 itha kugwiritsidwa ntchito pokhazikitsa m'mabungwe osiyanasiyana padziko lonse lapansi, kuyambira masukulu mpaka nyumba mpaka malo opangira ma data.Mwachidule, OM5 fiber ndi yabwino kuposa OM4 ponena za mtunda wotumizira, liwiro ndi mtengo.
Kufotokozera kwachitsanzo kwachitsanzo cha ma multi-mode fiber optic: Tengani chitsanzo cha ma multi-core multimode, (4A1b ndi 62.5/125µm, 4A1 ndi 50/125µm).
