Zhi Zhang et al. los ntawm Lub Tsev Kawm Ntawv ntawm Kev Sib Txuas Lus thiab Cov Ntaub Ntawv Engineering, University of Electronic Science thiab Technology ntawm Tuam Tshoj tau tsim lub constellation Reshaping chaotic encryption (CSCEn) scheme nrog cov txheeb cais faib tswj tau, raws li qhia hauv FIG 2. Firstly, orthogonal amplitud...

[Introduction] Lub wavelength division multiplexing thev naus laus zis tuaj yeem siv tag nrho cov peev txheej bandwidth loj uas coj los ntawm qhov tsawg-tsawg ntawm ib hom fiber ntau. Raws li qhov zaus (lossis wavelength) ntawm lub teeb nthwv dej ntawm txhua qhov channel, faib lub qhov rais qis ntawm cov fiber ntau rau hauv ntau ch...

Ua ntej, orthogonal amplitu...

一.Freight forwarder lwm yam nqi uas cov tswv yuav tsum paub Ntxiv nrog rau qhov "dawb huv" freight, muaj ntau yam xwm txheej, qee qhov yog them los ntawm tus tswv nkoj thiab qee qhov yog rau cov khoom xa tuaj .Sau los ntawm qhov chaw nres nkoj / chaw nres nkoj, thiab ib co yog sau los ntawm pem hauv ntej ...

Optical fiber transceiver yog Ethernet kis nruab nrab hloov dua siab tshiab chav tsev uas sib pauv luv luv-ntu twisted khub rau khub hluav taws xob teeb liab nrog cov teeb liab nyob deb. Kuj hu ua photoelectric converter nyob rau hauv ntau qhov chaw. Cov khoom no feem ntau yog siv nyob rau hauv qhov tseeb network envi ...

Cov kev xav sib txawv ua rau tib neeg muaj kev nkag siab sib txawv ntawm fiber ntau optic transceivers: Piv txwv li, raws li kev sib kis tus nqi, nws muab faib ua 10M, 100M fiber optic transceiver, 10/100M adaptive fiber optic transceiver thiab 1000M fiber optic transceiver> Raws li t. ..
