Nrog kev txhim kho txuas ntxiv ntawm kev sib txuas lus kho qhov muag, kev sib txuas lus kho qhov muag fiber ntau tau ntsib tsib tiam txij li thaum nws tshwm sim.Nws tau dhau los ua kom zoo dua qub thiab txhim kho ntawm OM1, OM2, OM3, OM4 thiab OM5 fiber ntau, thiab tau ua kom tsis tu ncua hauv kev sib kis thiab kis tau tus mob.Vim yog cov yam ntxwv thiab daim ntawv thov scenarios, OM5 fiber ntau tau qhia txog kev loj hlob zoo.
Thawj tiam optical fiber kev sib txuas lus system
1966-1976 yog theem kev txhim kho ntawm cov fiber ntau optical los ntawm kev tshawb fawb yooj yim mus rau kev siv tswv yim.Nyob rau theem no, multimode (0.85μm) optical fiber kev sib txuas lus nrog 850nm luv wavelength thiab 45 MB / s, 34 MB / s qis tus nqi tau pom.Nyob rau hauv cov ntaub ntawv ntawm lub amplifier, qhov kev ncua deb yuav ncav cuag 10 km.
Thib ob tiam optical fiber kev sib txuas lus system
Nyob rau hauv 1976-1986, lub hom phiaj ntawm kev tshawb fawb yog los txhim kho tus kis tau tus mob thiab ua rau kom cov kis tau tus mob nyob deb, thiab vigorously txhawb txoj kev loj hlob theem ntawm daim ntawv thov ntawm optical fiber kev sib txuas lus systems. kev khiav hauj lwm wavelength kuj tsim los ntawm 850nm luv wavelength mus rau 1310nm / 1550nm ntev wavelength, ua tiav ib hom fiber ntau kev sib txuas lus nrog ib tug kis tau tus mob ntawm 140 ~ 565 Mb / s.Nyob rau hauv cov ntaub ntawv ntawm lub amplifier, qhov kev ncua deb yuav ncav cuag 100 km.
Thib peb tiam optical fiber kev sib txuas lus system
Los ntawm 1986 mus rau 1996, kev tshawb fawb kev kawm ntawm ultra-loj muaj peev xwm thiab ultra-ntev deb tau nqa tawm los kawm txog cov cuab yeej tshiab ntawm optical fiber.A 1.55 μm dispersion hloov ib hom fiber ntau optic kev sib txuas lus tau siv nyob rau theem no.Cov fiber ntau siv cov txheej txheem kev hloov kho sab nraud (electro-optical device) nrog tus nqi sib kis mus txog 10 Gb / s thiab kis tau tus mob mus txog 150 km yam tsis muaj relay amplifier.
Plaub tiam optical fiber kev sib txuas lus system
1996-2009 yog lub sijhawm ntawm synchronous digital system optical fiber kis network.Qhov kev sib txuas lus kho qhov muag fiber ntau qhia txog optical amplifiers kom txo tau qhov kev thov ntawm cov neeg rov ua dua.Lub wavelength division multiplexing thev naus laus zis yog siv los ua kom qhov muag fiber ntau kis tau tus nqi (txog 10Tb / s) thiab kev sib kis deb.Nws tuaj yeem ncav cuag 160 km.
Lus Cim: Hauv xyoo 2002, ISO / IEC 11801 tau tshaj tawm cov txheej txheem ntawm multimode fiber ntau, faib cov multimode fiber ntau OM1, OM2 thiab OM3 fiber ntau.Xyoo 2009, TIA-492-AAAD tau txiav txim siab OM4 fiber ntau.
Thib tsib tiam optical fiber kev sib txuas lus system
Qhov kev sib txuas lus fiber ntau optical qhia txog kev siv tshuab optical soliton, thiab siv cov nyhuv nonlinear ntawm fiber ntau los ua kom cov mem tes yoj tiv thaiv qhov tawg ntawm qhov qub waveform.Nyob rau theem no, lub fiber-optic kev sib txuas lus tau ntse nthuav lub wavelength ntawm lub wavelength division multiplexer, thiab tus thawj 1530nm ~ 1570 nm txuas mus rau 1300 nm rau 1650 nm.Tsis tas li ntawd, nyob rau theem no (2016) OM5 fiber ntau yog officially launched.
