Dab tsi yog TFF thiab AWG?
TFFisThin Zaj Duab Xis Lim.
AWGis Arrayed Waveguide Gratin.
Hauv kev lag luam sib txuas lus kho qhov muag, TFFand AWGare siv dav rau DWDM lossis CWDM tov. Txhua tus muaj nws tus kheej zoo thiab qhov tsis zoo.
Thawj qhov peb yuav tsum xav txog yog tus naj npawb channel.Yog tias tus naj npawb channel loj dua 16, AWG yog qhov kev xaiv zoo dua vim tias AWG muaj qis dua IL thiab tus nqi. Yog tias yuav tsum muaj cov naj npawb channel yog 40, ces AWG tsuas yog kev daws teeb meem nkaus xwb. Nws yog ib qho nyuaj ua rau 40ch siv TFF.
Ib qho ntxiv uas peb yuav tsum xav txog yog yoj yoj channel yov.Tsuas yog, AWG zoo dua hauv DWDM (200GHz, 100GHz, 50GHz, thiab lwm yam), thiab TFF zoo rau CWDM.
Nqe yog ib qho tseem ceeb tshaj plaws.Tus nqi ntawm ib qho khoom yog nyob ntawm tsis yog nws cov nqi tsim khoom xwb tab sis kuj muag ntim.
Cov neeg feem ntau tau xav tias AWG tus nqi yog siab dua li TFF tus nqi. Tab sis hauv 5G daim ntawv thov, cov naj npawb channel tau siab thiab channel spacing yog DWDM spacing thiab kuj muag ntim tau siab (ntau dua ob peb txhiab toj hlis), ces AWG tus nqi tuaj yeem qis dua TFF tus nqi.
Hauv kev xaus, AWG zoo dua xaiv hauv rooj plaub hauv qab no:
- Channel naj npawb loj dua 8 ~ 16
- DWDM wavelength spacing yog yuav tsum tau
- Qhov ntau thiab tsawg yog ntau dua ntau pua pua hauv ib hlis
