Kune marudzi akasiyana efiber optic cable.Mamwe marudzi ari single-mode, uye mamwe marudzi ari multimode.Multimode fibers inotsanangurwa neiyo core uye cladding madhayamita.Kazhinji dhayamita yefiber multimode ingave 50/125 µm kana 62.5/125 µm.Parizvino, kune marudzi mana emhando dzakawanda-modhi fibers: OM1, OM2, OM3, OM4 uye OM5.Mavara ekuti “OM” anomirira optical multimode.Rudzi rumwe norumwe rwazvo rune maitiro akasiyana.
Standard
Imwe neimwe "OM" ine hushoma hweModal Bandwidth (MBW) inodiwa.OM1, OM2, uye OM3 faibha zvinotemerwa neISO 11801 chiyero, icho chinobva pane modal bandwidth ye multimode fiber.Muna Nyamavhuvhu we2009, TIA/EIA yakabvumidza uye yakaburitsa 492AAAD, iyo inotsanangura maitiro ekuita kweOM4.Kunyange vakagadzira mazita ekutanga ekuti "OM", IEC haisati yaburitsa mwero wakatenderwa wakaenzana unozopedzisira wanyorwa sefiber type A1a.3 muIEC 60793-2-10.
Zvinotsanangurwa
● OM1 tambo inowanzouya nebhachi reorange uye ine core size ye62.5 micrometers (µm).Inogona kutsigira gumi Gigabit Ethernet pakureba kusvika 33 metres.Iyo inonyanya kushandiswa kune zana Megabit Ethernet application.
● OM2 inewo ruvara rwebhachi reorange.Hukuru hwayo hwepakati i50µm pachinzvimbo che62.5µm.Inotsigira gumi Gigabit Ethernet pakureba kusvika 82 metres asi inonyanya kushandiswa kune 1 Gigabit Ethernet application.
● OM3 faibha ine ruvara rwejacket rweaqua.Kufanana neOM2, saizi yayo yepakati i50µm.Inotsigira gumi Gigabit Ethernet pakureba kusvika ku300 metres.Kunze kwe OM3 inokwanisa kutsigira 40 Gigabit uye 100 Gigabit Ethernet kusvika ku 100 metres.10 Gigabit Ethernet ndiyo inonyanya kushandiswa.
● OM4 inewo ruvara rwejacket yeaqua.Iyo imwezve kuvandudzwa kune OM3.Inoshandisawo 50µm core asi inotsigira gumi Gigabit Ethernet pakureba kusvika 550 metres uye inotsigira 100 Gigabit Ethernet pakureba kusvika 150 metres.
● OM5 fiber, inozivikanwawo seWBMMF (wideband multimode fiber), ndiyo itsva yemhando ye multimode fiber, uye inodzokera kumashure inoenderana neOM4.Iyo ine saizi yepakati yakafanana neOM2, OM3, uye OM4.Rudzi rweOM5 fiber jaketi rakasarudzwa se lime green.Yakagadzirwa uye yakatsanangurwa kuti itsigire kanokwana mana eWDM chiteshi pakumhanya diki kwe28Gbps pachiteshi kuburikidza ne850-953 nm hwindo.Rumwe ruzivo runogona kuwanikwa pa: Matatu Akakosha Yekutarisa paOM5 Fiber Optic Cable
Dhayamita: Iyo yepakati dhayamita yeOM1 ndeye 62.5 µm, zvisinei, pakati dhayamita yeOM2, OM3 uye OM4 ndeye 50 µm.

Ungasarudza sei Multimode Fiber?
Multimode fibers inokwanisa kuendesa kureba kwakasiyana pane akasiyana data data.Iwe unogona kusarudza yakanyanya kufanira zvinoenderana nechako application.Iyo max multimode fiber kureba kuenzanisa pane akasiyana data data inotsanangurwa pazasi.
