Kedu ihe bụ OM1, OM2, OM3 na OM4 Fiber?

Ọkọlọtọ

"OM" ọ bụla nwere bandwit Modal kacha nta (MBW) chọrọ.OM1, OM2, na OM3 fiber kpebisiri ike site na ọkọlọtọ ISO 11801, nke dabere na modal bandwit nke eriri multimode.N'August nke 2009, TIA/EIA kwadoro ma wepụta 492AAAD, nke na-akọwa njirimara arụmọrụ maka OM4.Ka ha mepụtara aha mbụ "OM", IEC ewepụtabeghị ọkọlọtọ akwadoro nke a ga-emecha detuo ya dị ka ụdị fiber A1a.3 na IEC 60793-2-10.

Nkọwapụta

● eriri OM1 na-abịakarị na jaket oroma ma nwee nnukwu nha nke 62.5 micrometer (µm).Ọ nwere ike na-akwado 10 Gigabit Ethernet na ogologo elu 33 mita.A na-ejikarị ya maka ngwa 100 Megabit Ethernet.

● OM2 nwekwara agba jaket a tụrụ aro nke oroma.Ogo isi ya bụ 50µm kama 62.5µm.Ọ na-akwado 10 Gigabit Ethernet n'ogologo ruo mita 82 mana a na-ejikarị 1 Gigabit Ethernet ngwa.

● fiber OM3 nwere agba jaket a tụrụ aro nke aqua.Dị ka OM2, isi ya bụ 50µm.Ọ na-akwado 10 Gigabit Ethernet n'ogologo ruo mita 300.E wezụga OM3 nwere ike ịkwado 40 Gigabit na 100 Gigabit Ethernet ruo 100 mita.10 Gigabit Ethernet bụ ihe a na-ejikarị eme ihe.

● OM4 nwekwara agba jaket a tụrụ aro nke aqua.Ọ bụ nkwalite ọzọ na OM3.Ọ na-ejikwa isi 50µm mana ọ na-akwado 10 Gigabit Ethernet n'ogologo na mita 550 yana ọ na-akwado 100 Gigabit Ethernet n'ogologo ruo mita 150.

● Fiber OM5, nke a makwaara dị ka WBMMF (fiber multimode fiber), bụ ụdị eriri multimode kachasị ọhụrụ, ọ na-adaba na azụ azụ na OM4.Ọ nwere otu isi nha ka OM2, OM3 na OM4.A na-ahọrọ agba nke jaket fiber OM5 dị ka akwụkwọ ndụ akwụkwọ ndụ lime.Emebere ya ma kọwaa ya iji kwado opekata mpe ọwa WDM anọ na opekata mpe 28Gbps kwa ọwa site na windo 850-953 nm.Enwere ike ịchọta nkọwa ndị ọzọ na: Nleba anya atọ dị egwu na OM5 Fiber Optic Cable

Dayameta: Isi dayameta nke OM1 bụ 62.5 µm, agbanyeghị, isi dayameta nke OM2, OM3 na OM4 bụ 50 µm.
