Tus lej account rau Huawei Fiber ONU HG8346r yog Telecomadmin, thiab tus password yog Admintelecom. Yog tias nws tsis ua haujlwm, koj tuaj yeem tawg nws. Cov kauj ruam yog raws li nram no:
1. Siv Huawei Optical ONU ONT pab kom qhib Telnet;
2. Tom qab nkag mus rau Telnet (username: root password: admin), siv lub backup cfg hais kom ua backup cov ntaub ntawv configuration hw_ * * *. XML ntawm koj optical modem (ua ke nrog tftp32).
1. Fiber optic kev sib txuas lus tau tsim sai heev rau hauv daim ntawv tseem ceeb ntawm cov ntaub ntawv kis tau tus mob niaj hnub no vim nws qhov zoo xws li cov zaus bandwidth thiab muaj peev xwm loj. Txhawm rau kom ua tiav kev sib txuas lus kho qhov muag, kho qhov muag hloov kho thiab demodulation yuav tsum tau ua. Yog li ntawd, raws li ib feem tseem ceeb ntawm fiber optic kev sib txuas lus systems, optical modems tau txais kev saib xyuas. Muaj ob hom optical modulators: ncaj qha modulators thiab sab nraud modulators, thaum kho qhov muag modulators muab faib ua ob hom: nrog thiab tsis muaj built-in preamplifiers.
2. Direct modulation thiab demodulators nrog built-in preamplifiers yog lub hom phiaj ntawm qhov kev tshawb fawb no. Direct modulation muaj qhov zoo ntawm kev yooj yim, kev lag luam, thiab kev yooj yim ntawm kev siv, thaum demodulators nrog built-in preamplifiers muaj cov yam ntxwv ntawm kev sib koom ua ke siab thiab me me.
3. Hloov cov ntaub ntawv kom xa mus rau hauv daim ntawv uas tuaj yeem xa los ntawm cov xov tooj wireless, uas yog, hloov cov teeb liab mus rau qhov zaus haum rau kev sib kis. Feem ntau hais lus, kev hloov pauv yog cov txheej txheem ntawm kev hloov lub teeb liab baseband rau hauv lub teeb liab ntau dua bandpass. Modulation yog ib txheej txheem ntawm kev siv cov teeb liab baseband los hloov lub amplitude, theem, los yog zaus ntawm high-frequency hauv av yoj nqa khoom raws li tej kev cai.
