Hauv 5G fronthaul tes hauj lwm, 25G optical SFP modules tau siv dav, tshwj xeeb 25G WDM optical SFP modules. Vim tias hom kev tsim kho qhov muag SFP no muaj peev xwm xa ntau lub cim ntawm ib leeg, nws txuag tau nyiaj fiber ntau, tab sis nws muaj cov nqi siab dua lwm cov qauv 25G. Tam sim no, 25G SFP28 LWDM optical SFP modules ntawm lub lag luam kuj tseem tuaj yeem ua tiav ntau lub teeb liab kis ntawm ib tus hluas, tab sis tus nqi qis dua. Yog li no, 25G SFP28 LWDM modules muaj qhov hloov los ua cov hloov pauv ntau dua thiab ruaj khov nyob hauv 5G fronthaul tes hauj lwm.
Lub npe puv ntawm LWDM yog LAN WDM. 25G SFP28 LWDM module muaj 12 nthwv cua, txhua tus ntawm O-band. Yim ntawm lawv yog tus qauv wavelengths uas tau muab faib ua O-band spectrum raws li 800GHz, thiab plaub seem nthwv dej yog 25G multiplexed. Plaub qhov ntev ntawm CWDM optical SFP modules yog 1269.23nm, 1332.41nm, 1313.73nm thiab 1291.10nm. Zoo ib yam li 25G WDM module, 25G SFP28 LWDM optical SFP modules kuj tseem siv tau WDM thev naus laus zis mus rau ntau yam wavelengths mus rau ib khub ntawm cov kho qhov muag, uas tuaj yeem txuag tau ntau ntawm cov khoom siv fiber ntau.
Cov qauv sib txuas ntawm 25G SFP28 LWDM optical SFP modules tau zoo tib yam li 25G CWDM / DWDM optical SFP modules. Nws yuav tsum tau siv ua ke nrog txuam Mux / Demux, uas yog, LWDM Mux / Demux. Koj tsuas yog yuav tsum tau ntxig plaub 25G LWDM optical SFP modules rau 25G hloov ntawm ob qho kawg, thiab tom qab ntawd siv 4 tib hom fiber ntau cov khoom siv los txuas cov optical SFP modules rau LWDM Muxes / Demuxes, thiab siv tib hom fiber ntau jumper siv. nruab nrab ntawm ob lub LWDM Muxes / Demuxes. Cov kab txuas nrog.
25G SFP28 LWDM optical SFP modules tuaj yeem pab txhawb ntau cov teeb liab kis ntawm ib qho fiber ntau. Nws them rau qhov kev sib kis loj ntawm 25G CWDM modules thiab tus nqi siab ntawm 25G DWDM optical SFP modules lasers, thiab txuag 5G fronthaul kis thaum tseem ruaj khov kis tau tus mob. Qhov no yog vim li cas nws yog qhov daws tau ruaj khov thiab raug nyiaj hauv 5G fronthaul tes hauj lwm, thiab nws tseem muaj txoj kev cia siab zoo hauv kev tsim 5G fronthaul tes hauj lwm yav tom ntej.
