OM1, OM2, OM3, OM4, le OM5 ke mefuta e fapaneng ea likhoele tsa fiber-optic tsa multimode, e 'ngoe le e 'ngoe e na le litšobotsi tse fapaneng tse amanang haholo-holo le bandwidth le sebaka sa phetisetso. Mona ke tlhaloso ea liphapang tsa bohlokoa:

OM1 (Mokgwa o Mongata wa Optical 1):

Faeba ea OM1 e na le bophara ba mantlha ba li-micrometer tse 62.5.

E tšehetsa Gigabit Ethernet ka bolelele bo fihlang ho limithara tse 275 le Gigabit Ethernet tse 10 ka bolelele bo fihlang ho limithara tse 33.

Hangata faeba ea OM1 e sebelisoa lits'ebetsong tse khutšoane ka har'a mehaho kapa litsi tsa data.

OM2 (Mokgwa o Mongata wa Mahlasedi wa 2):

Faeba ea OM2 e boetse e na le bophara ba mantlha ba li-micrometer tse 62.5.

E fana ka tshebetso e betere hanyane ho feta OM1, e tshehetsa Gigabit Ethernet ka bolelele bo fihlang ho dimithara tse 550 le 10 Gigabit Ethernet ka bolelele bo fihlang ho dimithara tse 82.

Faeba ea OM2 e sebelisoa hangata lits'ebetsong tse tšoanang le tsa OM1 empa e ka tšehetsa libaka tse telele.

OM3 (Mokgwa o Mongata wa Optical 3):

Faeba ea OM3 e na le bophara bo bonyenyane ba mantlha ba li-micrometer tse 50.

E tšehetsa 10 Gigabit Ethernet ka bolelele bo fihlang ho limithara tse 300 le 40/100 Gigabit Ethernet ka bolelele bo fihlang ho limithara tse 100.

Faeba ea OM3 e ntlafalitsoe bakeng sa tšebeliso le mehloli ea VCSEL (Vertical Cavity Surface Emitting Laser).

OM4 (Mokhoa o mongata oa Optical 4):

Faeba ea OM4 e boetse e na le bophara ba mantlha ba li-micrometer tse 50.

E fana ka ts'ebetso e phahameng ho feta OM3, e tšehetsa 10 Gigabit Ethernet ka bolelele bo fihlang ho limithara tse 550 le 40/100 Gigabit Ethernet ka bolelele bo fihlang ho limithara tse 150.

Faeba ea OM4 e tsamaisana le faeba ea OM3 ka morao 'me e na le theknoloji e tšoanang ea phetisetso e thehiloeng ho VCSEL.

OM5 (Mokgwa o Mongata wa Optical 5):

OM5 ke tlatsetso e ncha ho lelapa la OM fiber.

E boetse e na le bophara ba mantlha ba li-micrometer tse 50.

Faeba ea OM5 e tšehetsa ho ata ha wavelength division multiplexing (WDM) e lumellang matšoao a mangata ho fetisoa ka nako e le 'ngoe holim'a maqhubu a fapaneng a wavelength.

E etselitsoe ho tšehetsa bandwidth e phahameng libakeng tse telele, haholo-holo likhokahanong tsa litsi tsa data.

Ka bokhutšoanyane, leha mefuta ena eohle ea likhoele e le likhoele tsa mekhoa e mengata tse sebelisoang lits'ebetsong tse khutšoane ho isa ho tse mahareng, li fapana ka bophara ba mantlha, bandwidth, le libaka tse tšehetsoeng tsa phetisetso. OM1 le OM2 ke litekanyetso tsa khale tse nang le bophara bo boholo ba mantlha, ha OM3, OM4, le OM5 li fana ka bandwidth e phahameng le tšehetso bakeng sa litekanyetso tse potlakileng tsa Ethernet tse nang le bophara bo bonyenyane ba mantlha.
