Mafunso Ofunsidwa KawirikawiriKusiyana pakati pa OM1, OM2, OM3, OM4 ndi OM5 Multimode Fiber
Lumikizanani nafe kuti mupeze zitsanzo zambiri, malinga ndi zosowa zanu, sinthani zomwe mukufuna
funsani tsopanoKusiyana pakati pa OM1, OM2, OM3, OM4 ndi OM5 Multimode Fiber
OM1, OM2, OM3, OM4, ndi OM5 ndi mitundu yosiyanasiyana ya zingwe za fiber-optic za multimode, iliyonse ili ndi makhalidwe osiyanasiyana okhudzana ndi bandwidth ndi mtunda wotumizira. Nayi kusanthula kwa kusiyana kwakukulu:
OM1 (Optical Multimode 1):
Ulusi wa OM1 uli ndi mainchesi 62.5 pakati.
Imathandizira Gigabit Ethernet kutalika mpaka mamita 275 ndi Gigabit Ethernet 10 kutalika mpaka mamita 33.
Ulusi wa OM1 nthawi zambiri umagwiritsidwa ntchito pa ntchito zazifupi mkati mwa nyumba kapena malo osungira deta.
OM2 (Optical Multimode 2):
Ulusi wa OM2 ulinso ndi mainchesi 62.5 pakati.
Imapereka magwiridwe antchito abwino pang'ono kuposa OM1, imathandizira Gigabit Ethernet kutalika mpaka mamita 550 ndi Gigabit Ethernet 10 kutalika mpaka mamita 82.
Ulusi wa OM2 umagwiritsidwa ntchito kwambiri m'njira zofanana ndi OM1 koma ukhoza kuthandizira mtunda wautali.
OM3 (Optical Multimode 3):
Ulusi wa OM3 uli ndi mainchesi ang'onoang'ono apakati a mainchesi 50.
Imathandizira 10 Gigabit Ethernet kutalika mpaka mamita 300 ndi 40/100 Gigabit Ethernet kutalika mpaka mamita 100.
Ulusi wa OM3 umakonzedwa bwino kuti ugwiritsidwe ntchito ndi magwero a VCSEL (Vertical Cavity Surface Emitting Laser).
OM4 (Optical Multimode 4):
Ulusi wa OM4 ulinso ndi mainchesi 50 pakati.
Imapereka magwiridwe antchito apamwamba kuposa OM3, imathandizira 10 Gigabit Ethernet kutalika mpaka mamita 550 ndi 40/100 Gigabit Ethernet kutalika mpaka mamita 150.
Ulusi wa OM4 umagwirizana ndi ulusi wa OM3 ndipo uli ndi ukadaulo wofanana wa VCSEL.
OM5 (Optical Multimode 5):
OM5 ndiye chowonjezera chatsopano mu banja la OM fiber.
Ilinso ndi mainchesi 50 apakati.
Ulusi wa OM5 umathandizira kugawa kwa wavelength division multiplexing (WDM) komwe kumalola kuti zizindikiro zingapo zifalitsidwe nthawi imodzi pa ma wavelength osiyanasiyana.
Yapangidwa kuti ithandizire bandwidth yayikulu patali, makamaka m'malo olumikizirana a data center.
Mwachidule, ngakhale kuti mitundu yonse ya ulusi iyi ndi ulusi wa multimode womwe umagwiritsidwa ntchito mwachidule mpaka pakati, umasiyana mu core diameter, bandwidth, ndi mtunda wotumizira wothandizidwa. OM1 ndi OM2 ndi miyezo yakale yokhala ndi core diameter yayikulu, pomwe OM3, OM4, ndi OM5 imapereka bandwidth yayikulu komanso chithandizo cha miyezo ya Ethernet yothamanga yokhala ndi core diameter yaying'ono.
