1.Ua kom tag nrho cov kev pab cuam bandwidth ntawm optical fiber. Fiber ntau muaj peev txheej bandwidth loj (tsawg poob band). Wavelength division multiplexing thev naus laus zis ua rau muaj peev xwm kis tau tus mob fiber ntau los ntawm ob peb zaug mus rau kaum ob lossis ntau pua zaus tshaj li ntawm ib lub wavelength, yog li ua kom muaj peev xwm sib kis ntawm fiber ntau thiab txo tus nqi. Nws muaj txiaj ntsig zoo ntawm daim ntawv thov thiab tus nqi nyiaj txiag.

2. teeb liab pob tshab kis tau tus mob. Vim hais tias WDM system yog multiplexed thiab demultiplexed raws li qhov sib txawv wavelength ntawm lub teeb, nws tsis muaj dab tsi ua rau tus nqi ntawm lub teeb liab thiab hom hluav taws xob modulation, uas yog, cov ntaub ntawv yog "pob tshab" rau cov ntaub ntawv. Yog li ntawd, cov teeb liab uas muaj cov yam ntxwv sib txawv kiag li tuaj yeem kis tau, xws li ATM, SDH, IP thiab sib xyaw sib kis ntawm ntau yam kev pabcuam (suab, video, ntaub ntawv, thiab lwm yam), thiab lwm yam.

3. expansion thiab upgrade yog yooj yim thiab yooj yim, tsis muaj nqi. Nws yog qhov yooj yim los nthuav lub peev xwm ntawm qhov kev sib txuas lus fiber ntau optical los ntawm kev siv wavelength division multiplexer technology. Nyob rau hauv cov txheej txheem ntawm kev nthuav dav thiab kev loj hlob ntawm lub network, tsis tas yuav hloov pauv cov kab hluav taws xob kho qhov muag, tsuas yog hloov kho qhov muag transmitter thiab optical receiver, uas yog txoj kev nthuav dav zoo tshaj plaws. Thov mus rau lub tuam txhab lub vev xaib rau cov ntaub ntawv qhia: www.guangying.com / www.qdapt.com.
