Keeb kwm
Tus nqi ntawm cov ntaub ntawv sau niaj hnub no los ntawm cov neeg siv thiab cov lag luam yog qhov loj, thiab pheej loj tuaj. Yog li ntawd, kev khaws cia thiab nkag mus rau cov ntaub ntawv no kuj tseem xav tau ntau dua, xav tau cov ntaub ntawv ntau dua thiab cov ntaub ntawv thauj mus ntev dua. Ib qho ntawm peb cov neeg siv khoom tab tom saib ntxiv DWDM system rau 40G Network uas twb muaj lawm yav tom ntej thev naus laus zis hauv txoj hauv kev loj dua.
Kev sib tw
Lub chaw cia khoom hauv cov chaw khaws ntaub ntawv niaj hnub no tau nruab nrog 10G thiab 40G hloov pauv. Kev nce kev sib kis ntawm lub network yog qhov nyuaj tshwj xeeb tshaj yog rau 40G, vim tias qhov siab tshaj plaws ncav cuag 40G QSFP + optics yog txwv rau 40 km thiab txhua 40G interface xav tau fiber ntau ntawm cov chaw, tawm hauv qhov sib txawv rau cov chaw khaws ntaub ntawv sau. Cov neeg siv khoom network muaj qhov tsaus nti fiber ntau txuas ob qhov chaw tshaj 40km, thiab lawv nyuam qhuav paub qhov kev sib txuas ntawm cov chaw no.
Kev daws
Nrog rau cov peev nyiaj txuas loj, qhov kev daws teeb meem no pab txhawb 80G cov ntaub ntawv mus txog 60km yam tsis tas yuav tso cov fiber ntau ntxiv. Nyob rau hauv txoj kev no, ib qho 40G optical teeb liab tuaj yeem tawg mus rau hauv 4x10G cov teeb liab, thiab tom qab ntawd OEO hloov lawv mus rau qhov sib thooj DWDM wavelengths. Yog hais tias ntxiv dispersion conpensation modules thiab amplifiers, qhov kev ncua deb yuav ua tau ntau tshaj 60km. Piv txwv li, txawm tias 80 km tuaj yeem ua tau.
Raws li DWDM 10G 80km transceiver yog siv rau kev xa cov ntaub ntawv, peb siv lub attenuator los kho Rx lub zog ntawm optical transceiver nyob rau hauv thaj tsam ntawm -13dBm ~ -20 dBm kom tsis txhob hlawv lub transceiver.
Lub zog amplifier (BA) yog siv tom qab lub optical transmitter MUX thaum nyob rau hauv pem hauv ntej ntawm optical fiber kab kom muaj zog ntawm lub teeb kis tau tus mob. Lub pre-amplifier (PA) yog muab tso ua ntej lub optical receiver Mux tab sis tom qab lub optical fiber kab mus rau amplify lub tsis muaj zog optical teeb liab.
DWDM solution
Cov txiaj ntsig ntawm cov neeg siv khoom
Tus nqi-zoo 40GbE kev daws teeb meem yog qhov tseem ceeb rau kev xa cov kev txhawb nqa rau cov bandwidth ntau dua thiab qis dua latency. HTF 40G network kev daws teeb meem tso cai rau kev siv pheej yig thiab yooj yim 10Gb DWDM systems los txuas ntxiv kev pabcuam 40GbE, zam qhov xav tau ntawm cov khoom siv tshiab lossis rau kev tsim kho tshiab tshiab, muab kev tiv thaiv kev nqis peev tseem ceeb.
HTF tuaj yeem pab koj tsim coherent 400G / 200G / 100GDWDM/ OTN tov, DWDM Ib leeg lamda 100G / 200G / 400G Dual fiber / Ib leeg fiber ntau kis tau tus mob ntev.
