Tam sim no, 5G tau pib ua cov txheej txheem kev ua lag luam, tab sis cov txheej txheem tuav cov nyom coj mus rau qhov nce ntawm cov coj cov qauv siv tau kho qhov muag. Rau 5G rau pem hauv ntej kis, nyob rau hauv cov nqe lus ntawm kev nrawm, AAU tau qhia eCPRI raws tu qauv, thiab tus xa mus rau 25G tus nqi tau dhau los ua tus qauv ntawm ntau yam khoom siv tuam ntxhab. Vim tias qhov no, tus nqi txheem ntawm cov cab kuj lub network yuav txiav txim siab raws li kev sib dhos sib luag ntawm txhua txheej. Thaum kawg, nws xaus lus tias optical module nrog 50G ceev rau kis nruab nrab yog qhov kev xaiv tshaj plaws raug nqi.
Qhov laj thawj yog vim li cas WDM thiab bidi thev naus laus zis tau siv yog tias xav txog qhov nyuaj ntawm kev teeb tsa fiber ntau, kev siv hluav taws xob ntawm cov hluav taws xob optical fiber ntau tuaj yeem txhim kho los ntawm kev siv ob lub thev naus laus zis.
Tam sim no, 50G thiab 25G optical module yog qhov tseem ceeb tshaj plaws ntawm cov txheej nkag hauv kev tsim kho ntawm Tuam Tshoj Txawb, Tuam Tshoj Unicom thiab cov xov tooj sib txuas. Ntawm lawv, cov phiaj xwm ntau lawm ntawm 25G dual fiber bidirectional optical module tau paub tab heev, tab sis 50G PAM4 optical module tseem nyob rau theem pom zoo nyob rau hauv Suav teb, thiab nws cov qauv tseem nyob hauv cov txheej txheem tsim.
Cov hom ntawm 5G cov cab kuj kho qhov muag tshwj xeeb yog tsim los ntawm kev sib xyaw ntawm kev nrawm, ib leeg / ob chav fiber ntau thiab xim lub teeb, thiab sfp56 yog lub ntsiab ntim hom. Tom ntej no, HTF yuav qhia ob yam hauv qab no 50G optical module:
1. 50G ib leeg fiber bidirectional xim module, SFP28 pob, BIDI, ib hom, nruab nrab lub zog ntev ntawm 1309nm-TX / 1295nm-RX, LC yooj yim txuas, ua haujlwm kub ntawm 0-70 ℃, qhov siab tshaj plaws kis tau mus txog 40km.
2. 50G SFP56 SR optical module, lub suab yoj yog 850nm, multimode, duplex LC txuas, ua haujlwm kub ntawm 0-70 ℃, tuaj yeem siv nrog OM3 thaj qaum, qhov kis tau siab tshaj yog 70m, lossis nrog OM4 thaj qaum, qhov kis tau ntau tshaj plaws deb yog 100m.
50G optical modules feem ntau yog siv rau kev sib kis nruab nrab thiab thim rov qab hauv kev tsim kho ntawm 5G tes hauj lwm. Raws li lub chaw tsim hluav taws xob kho qhov muag, HTF tuaj yeem muab cov khoom lag luam saum toj saud, thiab cov khoom tuaj yeem sib haum nrog Huawei, Cisco, H3C, Ruijie thiab lwm hom kev hloov khoom lag luam. 5G backhaul npog npog thaj tsam ntawm kev nkag mus rau txheej, sib xyaw txheej thiab txheej txheej txheej. Cov chaw hauv nroog nkag tau siv feem ntau 25G, 50G, 100g xim xim kho qhov muag, thaum lub txheej sib sau ua ke thiab cov tub ntxhais txheej feem ntau siv DWDM xim xim kho qhov muag nrog cov ceev ntawm 100G, 200G thiab 400G.
Tam sim no, txhua daim ntawv thov teeb meem muaj ntau lub khoos phis tawj module kho teeb meem thiab hom. 5G cov coj kev kho qhov muag siv tshuab daws teeb meem xav tau txuas ntxiv nrhiav qhov muaj txiaj ntsig thaum khaws cov kev sib txawv thiab tsom xam pom Tus nqi tuaj yeem raug txo los ntawm kev saib xyuas kev nqis peev thiab ntsuas cov peev txheej ntawm cov kev daws teeb meem tseem ceeb.
