"OM" mukutaurirana kwemaziso zvinoreva "Optical Multi-mode".Optical mode, inova chiyero chemultimode fiber kuratidza fiber giredhi.Parizvino, TIA neIEC yakatsanangurwa faibha chigamba tambo zviyero ndeye OM1, OM2, OM3, OM4, uye OM5.
Chekutanga pane zvese, chii chinonzi multimode uye single mode?
Single Mode Fiber is optical fiber inobvumira nzira imwe chete yekufambisa.Iyo dhayamita yepakati inenge 8 kusvika 9 μm uye dhayamita yekunze inenge 125 μm. Multimode Optical Fiber inobvumira nzira dzakasiyana dzechiedza kuti dziendeswe pamusoro pefiber imwe chete nehupamhi hwepakati hwe 50 μm uye 62.5 μm.Single-mode fiber inotsigira kureba kwekutapurirana madaro pane multimode fiber.Mu100Mbps Ethernet kusvika ku1G Gigabit, imwe-modhi fiber inogona kutsigira kutapurirana madaro pamusoro pe5000m.Multimode faibha inokodzera zvepakati uye pfupi chinhambwe uye diki inokwana fiber optic masisitimu ekutaurirana.
Chiivari tiye musiyano pakati peOM1, OM2, OM3, OM4, OM5?
Kazhinji,OM1 ndeye 62.5/125um.OM2 inowanzoitika 50/125um;OM3 ndeye 850nm laser-yakagadziridzwa 50um yakakosha multimode fiber.Mu10Gb / s Ethernet ne850nm VCSEL, iyo fiber transmission kureba inogona kusvika 300m.OM4 ishanduro yakagadziridzwa yeOM3.OM4 multimode faibha inogonesa iyo yekusiyanisa mode kunonoka (DMD) inogadzirwa neOM3 multimode fiber panguva yekufambisa-kumhanya.Naizvozvo, kureba kwekutapurirana kwakagadziridzwa zvakanyanya, uye faibha yekufambisa kureba inogona kusvika 550m.Iyo OM5 fiber patch cord ndiyo chiyero chitsva chefiber patch cords inotsanangurwa neTIA neIEC ine fiber dhayamita ye50/125 μm.Kuenzaniswa neOM3 uye OM4 fiber patch cords, OM5 fiber patch cords inogona kushandiswa kune yakakwirira bandwidth applications.The bandwidth uye kureba kure zvakasiyana pakutumira pamazinga akasiyana.
Chii chinonzi OM5 fiber patch cord?
Inozivikanwa seWideband Multimode Fiber Patch Cable (WBMMF), OM5 fiber is laser-optimized multimode fiber (MMF) yakagadzirirwa kutsanangura bandwidth maitiro ewavelength division multiplexing (WDM).Iyo itsva fiber classification nzira yakagadzirirwa kutsigira akasiyana-siyana e "pfupi" wavelengths pakati pe850 nm uye 950 nm, iyo inokodzera yakakwirira bandwidth application mushure mepolymerization.Iyo OM3 neOM4 zvakagadzirirwa zvakanyanya kutsigira imwe wavelength ye850 nm.
Ndeupi musiyano uripo pakati peOM3 neOM4?
1.Different jekete ruvara
Kuti usiyanise pakati peakasiyana fiber jumpers, mavara akasiyana ekunze sheath anoshandiswa.Kune asiri echiuto maapplication, single mode faibha inowanzova jekete rekunze reyero.Mune multimode fiber, OM1 uye OM2 iorenji, OM3 uye OM4 ibhuruu yemvura, uye OM5 igirini yemvura.
2.Different application scope
OM1 uye OM2 zvakashandiswa zvakanyanya muzvivako kwemakore akawanda, zvichitsigira Ethernet transmissions kusvika ku1GB.OM3 uye OM4 fiber optic cables inowanzoshandiswa mu data center cabling environments kutsigira 10G kana kunyange 40 / 100G high-speed Ethernet nzira. 40Gb / s uye 100Gb / s kutumira, iyo OM5 inoderedza nhamba yefibers inogona kutumirwa nekukurumidza.
OM5 multimode fiber maitiro
1. Mafibhi mashoma anotsigira maapplication epamusoro ebandwidth
Iyo OM5 fiber patch tambo ine yekushanda wavelength ye850/1300 nm uye inogona kutsigira angangoita mana wavelengths.Iyo yakajairika yekushanda wavelengths yeOM3 uye OM4 ndeye 850 nm uye 1300 nm.Izvi zvinoreva kuti, tsika yeOM1, OM2, OM3, uye OM4 multimode fibers ine chiteshi chimwe chete, nepo OM5 ine mitsara ina, uye simba rekufambisa rinowedzerwa nechina.Kubatanidza short-wavelength division multiplexing (SWDM) uye parallel. tekinoroji yekufambisa, OM5 inongoda 8-core wideband multimode fiber (WBMMF), iyo inogona kutsigira 200/400G Ethernet application, inoderedza zvakanyanya nhamba yefiber cores.Kusvika zvishoma, mari ye wiring ye network inoderedzwa.
2.Farther kutapurirana kure
Iyo yekufambisa kureba kweOM5 fiber yakareba kupfuura iyo yeOM3 uye OM4.Iyo OM4 fiber yakagadzirirwa kutsigira kureba kweanenge 100 metres ine 100G-SWDM4 transceiver.Asi OM5 faibha inogona kutsigira kusvika 150 metres pakureba ine transceiver yakafanana.
3.Lower fiber kurasikirwa
Iyo attenuation yeOM5 Broadband multimode tambo yakaderedzwa kubva ku3.5 dB/km kune yapfuura OM3, OM4 tambo kusvika 3.0 dB/km, uye bandwidth inodiwa pa953 nm yakawedzera.
Iyo OM5 ine saizi yefiber yakafanana neOM3 uye OM4, zvinoreva kuti inoenderana zvizere neOM3 uye OM4.Izvo hazvidi kuchinjwa mune iripo wiring application OM5.
OM5 faibha inowedzera scalable uye inochinjika, ichigonesa kukurumidza kukurumidza kufambisa network ine mashoma multimode fiber cores, nepo mutengo uye simba rekushandisa zvakaderera zvakanyanya kupfuura single mode fiber.Naizvozvo, ramangwana richashandiswa zvakanyanya mu100G/400G/1T data yakakura kwazvo. centers.
