● Khoom Qhia:
13101490 / 1550nm FWDM muaj peev xwm paub txog cov kev sib txuam thiab kev sib tw ntawm ob txoj kev sib txuas lus 1490/1310 thiab 1550. Nws yuav ua kom muaj peev xwm ntawm ib tus fiber ntau los ua kom tiav kev sib txuas lus, yog li ntawd siv ntau qhov kev hloov kho lub network thiab nthuav tawm, lossis qhia txog kev lag luam tshiab thiab lwm yam. Lim hom WDM yog raws li kev pov thawj yeeb yaj kiab lim hlau. Qhov WDM no yog siv rau cov kev sib txuas lus fiber ntau ntawm fiber ntau thiab EDFA qhov chaw uas yuav tsum muaj kev sib tw thiab sab nrauv.
