Muxponder vs Transponder: Nkag siab qhov txawv
Apr 25, 2026| Cov kab lus feem ntau ua rau cov lus nug muxponder vs transponder raws li kev hais lus. Txhua tus ua dab tsi, lawv txawv li cas. Qhov teeb meem tiag tiag yog kev ua haujlwm, thiab nws tshwm sim ntau lub hlis tom qab lub nkoj kho vajtse. Peb tsim ob hom OTN kab phaib ntawm peb lub chaw Shenzhen, thiab kev txhawb nqa kev sib tham uas siv sij hawm ntev tshaj plaws yeej tsis hais txog cov khoom specs. Lawv yog hais txog cov neeg muas zaub uas yuav lub cuab yeej zoo rau qhov tsis ncaj ncees lawm network scenario. Ib rooj plaub xyoo tas los: huab - tus neeg teb xov tooj tau xa tawm 400G muxponder ntawm ob - qhov chaw DCI txuas tsis muaj dab tsi tab sis 100GE. Lawv qhov kev kwv yees kev tsheb khiav tau suav tias yog kev sib koom ua ke hauv cheeb tsam uas tsis tau kaw, thiab ob ntawm plaub qhov chaw nres nkoj ntawm cov neeg siv khoom zaum tsaus rau yim lub hlis. Thaum kawg lawv nug seb puas yog ib khub ntawm -channel transponders yuav yooj yim dua thiab pheej yig dua, peb tau khiav cov lej ua ke. Txoj kev transponder yuav tau txiav lawv cov khoom siv ib qho chaw nres nkoj tus nqi los ntawm kwv yees li 40%, nrog rau lub zog qis dua ntawm qhov ntawd. Lub muxponder tsis yog cov khoom tsis raug. Nws yog cov khoom tsis raug rau qhov kev sib tw tsheb.
Yuav ua li cas Transponder thiab Muxponder Signal Mapping txawv
Transponder
Lub transponder ua qhov 1: 1 optical -hluav taws xob- hloov kho qhov muag. Ib tus neeg siv lub teeb liab nkag mus, ib qho ITU-daim phiaj DWDM wavelength tawm los. Lub teeb liab tau txais retimed, reshaped, thiab re- amplified los ntawm3R kev ua haujlwm, tab sis daim ntawv qhia piv txwv nyob ib -rau-ib.
Muxponder
Lub muxponder qhwv tib lub cav OEO hauv ib txheej txheej. Ntau qhov qis dua - tus nqi tus neeg siv cov teeb liab tau teeb tsa rau hauv OTN ntim ib ITU-T G.709, tom qab ntawd multiplexed mus rau ib qhoib zaug siab dua - tus nqi wavelength. Plaub 100G ntws dhau los ua ib qho 400G lambda.
Cov zis yog N: 1 es tsis txhob 1: 1, uas txhais tau hais tias tsawg dua wavelengths noj rau tib aggregate throughput. Qhov kev ua tau zoo ntawd yog qhov xwm txheej. Nws tuav thaum koj ua tiav cov neeg siv khoom ports, thiab thaum cov kev pabcuam sib sau ua ke sib koom ua ke SLA cov cai. Hauv kev sib xyaw- ib puag ncig kev tsheb khiav nrog kev xav tau kev tiv thaiv ywj pheej, cov xwm txheej no tawg sai dua li cov khoom luv luv qhia. Peb taug kev los ntawm qhov chaw so tshwj xeeb ntxiv mus.
Vim Li Cas Latency Splits Muxponder -Kev Txiav Txim Siab Ua Ntej Tus Nqi Ua
Txhua OEO hop ntxiv kev ua haujlwm qeeb. Kev lag luam cov ntaub ntawv muab qhov chaw rau qhov tsawg kawg nkaus - cov khoom siv transponder, tsis muaj OTN wrapping thiab tsis muaj FEC qhov twg cov kab ntawv txuas tso cai rau nws, qhov chaw nyob ib ncig ntawm 10 mus rau 15 microseconds ib kis. Cov duab tiag tiag nyob ntawm qhov tshwj xeeb DSP thiab cov qauv qauv (TelcoCloudBridge). Thaum koj ntxiv OTN encapsulation, FEC encode/decode, thiab ODU multiplexing, latency nce. Ntau npaum li cas nyob ntawm tus neeg muag khoom tus qauv DSP, uas yog vim li cas thov rov qab - rau - rov qab cov ntaub ntawv ntsuas latency hauv koj RFP tseem ceeb dua li kev nyeem cov ncauj lus tshwj xeeb.
Hauv pebDCI project kev sab laj, peb tshuaj ntsuam nrog sub-100-microsecond ib-txoj kev ncua nyiaj txiag.
