Ib qho yog Dense Wavelength Division Multiplexing, uas siv LAN WDM wavelength txhais los ntawm 802.3, sau ua LWDM, uas yog siv rau hauv 10km qeb ntawm 100GBASE-LR4.
Qhov thib ob yog ntxhib ntoob sib faib ntau yam. Cov xaiv 20nm wavelength luv, luv dua li CWDM, feem ntau yog siv hauv 2km cov ntaub ntawv chaw. Peb tseem paub tias daim ntawv thov ntawm 100G optical module tau muab piv rau cov kev sib txuas lus hauv cov chaw hauv cov chaw, yog li CWDM cov xov tooj kev lag luam muaj kev paub tab heev, thiab nws txoj kev xaiv nthwv dej tau dhau los ua kev daws teeb meem.
100G LAN WDM tau cais raws li qhov kev ncua deb yav dhau los. Tsis muaj 2km cov ntaub ntawv, vim hais tias LAN cheeb tsam thaj chaw network tsis tshua muaj siv qhov kev ncua deb, tsuas yog SR luv luv, LR nyob deb li cas, thiab lwm yam ..., tab sis saib daim duab saum toj no, cov ntaub ntawv nruab nrab yog qhov muaj zog thiab txhim kho sai ntawm 802.3 qhov deb tam sim no ntxiv ob qho kev ncua deb ntawm 500 meters thiab 2km, DR4 thiab FR4, ntxiv rau SR4 thiab LR4 (10km). KR, SR, CR, SR, DR, FR, LR, ER thiab ZR hauv Y4T12 optical module
Kev xa cov ntaub ntawv nruab nrab yog 100 meters, 500 meters, thiab 2km. Txawm hais tias cov koom haum MSA no tsis yog cov koom haum ua lag luam, cov kev ua lag luam yog loj. Lawv tau tsim CWDM4, 2km kev siv, thiab tom qab ntawd ntxiv 10km ntsuas. Y4T209 Ntau qhov kev pom zoo MSA, Y2T4 100G optical module MSA-CWDM4, Y2T127 100G 10km 20km 40km ntev-deb optical module 4WDM MSA
