"OM" pakulankhulana kwamaso amatanthauza "Optical Multi-mode".Optical mode, yomwe ndi muyezo wa multimode fiber kuwonetsa giredi ya fiber.Pakali pano, TIA ndi IEC zomwe zimatanthauzidwa za fiber patch cord miyezo ndi OM1, OM2, OM3, OM4, ndi OM5.
Choyamba, multimode ndi single mode ndi chiyani?
Single Mode Fiber ndi fiber optical yomwe imalola njira imodzi yokha yopatsira.Chigawo chapakati chimakhala pafupifupi 8 mpaka 9 μm ndipo m'mimba mwake ndi pafupifupi 125 μm. Multimode Optical Fiber imalola mitundu yosiyanasiyana ya kuwala kuti iperekedwe pamtundu umodzi wokhala ndi pakati pa 50 μm ndi 62.5 μm.Ulusi wamtundu umodzi umathandizira mtunda wautali wotumizira kuposa ma multimode fiber.Mu 100Mbps Efaneti ku 1G Gigabit, single-mode CHIKWANGWANI angathandizire kufala mtunda pa 5000m.Multimode CHIKWANGWANI ndi yoyenera kwa mtunda wapakatikati ndi waufupi komanso kachitidwe kakang'ono ka fiber optic communication.
Chanindi tKodi pali kusiyana pakati pa OM1, OM2, OM3, OM4, OM5?
Nthawi zambiri, OM1 ndi ochiritsira 62.5/125um.OM2 ndi ochiritsira 50/125um;OM3 ndi 850nm laser-wokometsedwa 50um core multimode CHIKWANGWANI.Mu 10Gb / s Ethernet ndi 850nm VCSEL, mtunda wa fiber transmission ukhoza kufika 300m.OM4 ndi njira yowonjezera ya OM3.OM4 multimode fiber imakulitsa kuchedwa kwamitundu yosiyanasiyana (DMD) yopangidwa ndi OM3 multimode fiber panthawi yotumiza mwachangu.Choncho, mtunda kufala kwambiri bwino, ndi CHIKWANGWANI kufala mtunda akhoza kufika 550m.Chingwe cha OM5 fiber patch ndi muyezo watsopano wa zingwe za fiber patch zomwe zimatanthauzidwa ndi TIA ndi IEC zokhala ndi fiber diameter ya 50/125 μm.Poyerekeza ndi OM3 ndi OM4 fiber patch zingwe, zingwe za OM5 fiber patch zingagwiritsidwe ntchito pa mapulogalamu apamwamba a bandwidth.
Kodi OM5 fiber patch chingwe ndi chiyani?
Wodziwika kuti Wideband Multimode Fiber Patch Cable (WBMMF), OM5 fiber ndi laser-optimized multimode fiber (MMF) yopangidwa kuti iwonetsere mawonekedwe a bandwidth for wavelength division multiplexing (WDM).Njira yatsopano yamagulu amtundu wa fiber idapangidwa kuti izithandizira mafunde "afupi" osiyanasiyana pakati pa 850 nm ndi 950 nm, omwe ndi oyenera kugwiritsa ntchito ma bandwidth apamwamba pambuyo polima.Ma OM3 ndi OM4 adapangidwa makamaka kuti azithandizira kutalika kwa 850 nm.
Kodi pali kusiyana kotani pakati pa OM3 ndi OM4?
1.Mtundu wosiyana wa jekete
Pofuna kusiyanitsa pakati pa ma jumper osiyanasiyana a fiber, mitundu yosiyanasiyana ya sheath yakunja imagwiritsidwa ntchito.Kwa osakhala ankhondo, ulusi wa single mode nthawi zambiri umakhala jekete lakunja lachikasu.Mu multimode fiber, OM1 ndi OM2 ndi lalanje, OM3 ndi OM4 ndi madzi a buluu, ndipo OM5 ndi madzi obiriwira.
2.Different ntchito kuchuluka
OM1 ndi OM2 zakhala zikugwiritsidwa ntchito kwambiri m'nyumba kwa zaka zambiri, kuthandizira kutumiza kwa Ethernet mpaka 1GB.OM3 ndi OM4 fiber optic zingwe zimagwiritsidwa ntchito m'madera a data center cabling kuthandizira 10G kapena 40 / 100G njira zothamanga kwambiri za Ethernet. Kutumiza kwa 40Gb / s ndi 100Gb / s, OM5 imachepetsa kuchuluka kwa ulusi womwe ungathe kufalikira mofulumira kwambiri.
OM5 multimode fiber mawonekedwe
1. Ulusi wocheperako umathandizira kugwiritsa ntchito ma bandwidth apamwamba
Chingwe cha OM5 fiber patch chili ndi kutalika kwa 850/1300 nm ndipo chimatha kuthandizira mafunde osachepera anayi.Mafunde omwe amagwira ntchito a OM3 ndi OM4 ndi 850 nm ndi 1300 nm.Izi zikutanthauza kuti, chikhalidwe cha OM1, OM2, OM3, ndi OM4 multimode fibers chili ndi njira imodzi yokha, pamene OM5 ili ndi njira zinayi, ndipo mphamvu yopatsirana ikuwonjezeka ndi kanayi. teknoloji yotumizira, OM5 imangofunika 8-core wideband multimode fiber (WBMMF), yomwe ingathandize 200 / 400G Ethernet ntchito, kuchepetsa kwambiri chiwerengero cha fiber cores.Pang'ono pang'ono, mtengo wa wiring wa maukonde umachepetsedwa.
2.Farther kufala mtunda
Mtunda wotumizira wa OM5 fiber ndi wautali kuposa wa OM3 ndi OM4.Chingwe cha OM4 chapangidwa kuti chithandizire kutalika kwa mita pafupifupi 100 ndi transceiver ya 100G-SWDM4.Koma fiber ya OM5 imatha kuthandizira mpaka mamita 150 m'litali ndi transceiver yomweyo.
3.Kutsika kwa fiber
Kutsika kwa chingwe cha multimode cha OM5 chachepetsedwa kuchokera ku 3.5 dB / km kwa OM3 yapitayi, chingwe cha OM4 kufika ku 3.0 dB / km, ndipo chofunika cha bandwidth pa 953 nm chawonjezeka.
OM5 ili ndi kukula kwa fiber monga OM3 ndi OM4, zomwe zikutanthauza kuti imagwirizana kwathunthu ndi OM3 ndi OM4.Sichiyenera kusinthidwa mu pulogalamu yomwe ilipo ya OM5.
OM5 fiber imakhala yowonjezereka komanso yosinthika, yomwe imapangitsa kuti pakhale maulendo othamanga kwambiri pa intaneti ndi ma multimode fiber cores ochepa, pamene mtengo ndi mphamvu zogwiritsira ntchito mphamvu ndizochepa kwambiri kusiyana ndi fiber mode imodzi. malo.
