Optical transceiver yog ib qho khoom siv uas hloov ntau yam E1 teeb liab rau hauv cov teeb liab optical.Optical transceiver tseem hu ua optical kis khoom siv.Optical transceivers muaj tus nqi sib txawv raws li tus naj npawb ntawm E1 (uas yog, 2M) cov chaw nres nkoj xa mus.Feem ntau, qhov tsawg tshaj plaws optical transceiver tuaj yeem xa 4 E1s.Tam sim no qhov loj tshaj plaws optical transceiver tuaj yeem xa 4032 E1s, thiab txhua E1 suav nrog 30 xov tooj.Yog li, qhov optical transceiver 2m txhais li cas, thiab kev sib raug zoo ntawm optical transceiver E1 thiab 2M yog dab tsi?

Hom optical transceivers, optical transceivers muab faib ua 3 pawg: PDH, SPDH, SDH.PDH optical transceivers yog me me-muaj peev xwm optical transceivers, feem ntau siv ua khub, hu ua point-to-point applications, thiab lawv cov peev xwm feem ntau yog 4E1, 8E1, thiab 16E1.SDH optical transceiver muaj peev xwm loj, feem ntau 16E1 txog 4032 E1, SPDH optical transceiver, nruab nrab ntawm PDH thiab SDH.Feem ntau hais lus, optical transceiver yog ntau dua ntawm PDH optical transceiver, uas yog ib qho khoom siv hluav taws xob hloov dua siab tshiab.Feem ntau, optical transceiver nrog ib qho chaw nres nkoj kho qhov muag thiab plaub 2M tus nqi hluav taws xob qhov chaw nres nkoj yog qhov ntau tshaj.Cov neeg ua haujlwm hauv xov tooj feem ntau siv nws los xa cov suab paj nruag.Nyob rau hauv lub hauv paus chaw ua hauj lwm, lub optical davhlau ya nyob twg converts 2M hluav taws xob teeb liab mus rau hauv ib tug optical teeb liab thiab xa mus rau lub optical cable.Tom qab ncav cuag tus neeg siv kawg, cov teeb liab kho qhov muag tau hloov mus rau hauv 2M hluav taws xob teeb liab, uas yog, 2M kev pabcuam raug xa mus rau cov khoom siv suab xws li PCM.Thiab fiber ntau optic transceivers tau siv ntau dua hauv kev sib txuas lus cov ntaub ntawv.Nws kuj yog ib yam khoom siv photoelectric hloov dua siab tshiab.Feem ntau, muaj ntau tshaj ib qho chaw nres nkoj optical thiab ob peb Ethernet ports.Nws hloov cov teeb liab kho qhov muag rau hauv Ethernet teeb liab, uas yog siv los xa cov ntaub ntawv kev pabcuam rau cov ntaub ntawv sib txuas lus xws li routers lossis keyboards.

Rau optical transceivers, 2M yeej txhais tau hais tias qhov kawg 1550 wavelength muaj 2M bandwidth, uas yog siv los xa 485 cov ntaub ntawv tswj, thiab muaj 1.25G, 155M thiab cov zoo li, uas yog bandwidth xav tau rau kev sib kis video, pib 1 channel ntawm video. xav tau 155M.Optical transceivers E1 thiab 2M tsuas yog sib txawv hauv kev qhia.E1 yog qhov kev qhia ntawm pab pawg nyob rau hauv European tus qauv ntawm PDH (suav nrog rau North American standard pawg yog T1, piv txwv li 1.5M).Rau European tus qauv E1 tus nqi yog 2M, yog li 2M feem ntau siv los sawv cev E1.Nws tseem tuaj yeem hais tias E1 yog lub npe tshawb fawb thiab 2M yog lub npe nrov.Nyob rau hauv lub sijhawm SDH, tus nqi ntawm VC12 (thiab TU-12) hauv SDH multiplexing kev sib raug zoo yog ze rau 2M (qhov tseeb tsis yog 2048K), qee cov neeg kuj hu cov 2M, uas yog qhov tsis raug.Rau E1 chaw nres nkoj ntawm lub cuab yeej, nws feem ntau hu ua 2M chaw nres nkoj, thiab nws yuav tsum yog E1 eloquence kom meej.Ua ke, 34M chaw nres nkoj yuav tsum yog E3 chaw nres nkoj, thiab 45M chaw nres nkoj yuav tsum yog DS3 chaw nres nkoj.140M chaw nres nkoj yog E4 chaw nres nkoj.
