200G QSFP56 Module: Specifications & Applications

Apr 15, 2026|

Peb lub hlis dhau los, peb tau pab tus neeg siv khoom siv AI inference pawg nruab nrog Arista 7050CX3 keyboards. Lawv tau xaj 200G QSFP56 modules, cia siab tias yuav poob yooj yim- hauv kev hloov kho los ntawm lawv qhov teeb tsa 100G uas twb muaj lawm.

Cov modules tuaj txog thiab zaum huv si rau hauv QSFP tawb uas tsis muaj teeb meem ntawm lub cev. Txawm li cas los xij, cov kev sib txuas tsis tuaj yeem tshwm sim: LEDs tseem tsaus, thiab cov ntawv hloov pauv tau tshaj tawm qhov "tsis txhawb nqa transceiver" yuam kev. Tom qab peb lub lis piam ntawm txoj haujlwm qeeb, lub hauv paus ua rau raug txheeb xyuas: Memory Technology Platform 3 ASIC hauv cov keyboards no tsis txhawb 50G PAM4 hluav taws xob signaling. Yuav tsum muaj kev sib pauv platform, tsis yog hloov kho firmware xwb.

Qhov no scenario plays tawm ntau dua li cov neeg muag khoom lag luam qhia. 200G QSFP56 daim ntawv zoo haum rau tib lub cev tawb li QSFP28-zoo tib yam qhov ntev, tib 38-pin connector. Tab sis hluav taws xob sib raug zoo yog ib lo lus nug sib txawv kiag li, thiab nws yog ib qho uas txiav txim siab seb koj lub sij hawm kev yuav khoom tuav los yog daim ntawv.

Lub Tsev Kawm Txuj Ci: Dab tsi 200G QSFP56 Qhov Yuav Tsum Tau

A 200G QSFP56 optical transceiver ua haujlwm ntawm plaub txoj kab ntawm 50Gbps txhua, siv PAM4 kev hloov kho dua li NRZ teeb liab hauv 100G QSFP28 modules. PAM4 encodes ob lub cim rau ib lub cim es tsis txhob ntawm ib qho - qhov no yog qhov koj muab ob npaug ntawm kev nkag mus yam tsis muaj ob npaug ntawm txoj kab suav. Tab sis PAM4 lub teeb liab-rau- suab nrov margin yog kwv yees li 9dB qis dua NRZ, uas ua rau Forward Error Correction tsis yog{14}} xaiv tau.

Qhov kev cuam tshuam zoo: koj qhov hloov ASIC thiab firmware yuav tsum tau txhawb nqa 50G PAM4 txoj kab thiab RS (544,514) FEC ua. Lub cev qhov chaw nres nkoj qhia koj tsis muaj dab tsi txog qhov no. Cisco tshaj tawm lawv Transceiver Module Group compatibility matrix ntawm tmgmatrix.cisco.com; Arista tuav cov ntaub ntawv zoo sib xws. Tshawb xyuas cov no ua ntej qhov kev txiav txim yuav nkoj yog qhov sib txawv ntawm kev xa khoom zoo thiab qhov xwm txheej uas qhib cov kab lus no.

Cov specs no los ntawm IEEE 802.3bs thiab cov ntaub ntawv chaw tsim khoom. Tab sis ntawm no yog lub rooj tsis qhia rau koj: xaiv qhov kev ntsuas los ntawm qhov deb tsis nco qab cov lus nug txog kev tsim kho vaj tse. FR4 tus tib - hom optics xav tau cov txheej txheem tu sib txawv, kev siv nyiaj tsawg dua, thiab feem ntau sib txawv thaj vaj huam sib luag ntau dua li qhov koj tab tom khiav rau multimode SR4 txuas. Thaum peb spec FR4 rau lub tsev kawm ntawv qaum tsev kawm ntawv ntau tshaj 500m, fiber ntau hloov pauv ib leeg ntxiv 15-25% rau qhov project BOM dhau qhov module nqi sib txawv nws tus kheej.

Nqe Lus nug Tsis muaj leej twg xav muab sau rau hauv

Raws li peb cov nqi catalog tam sim no, FB-LINK's200G QSFP56 optical transceiver moduleskhiav 50-70% hauv qab no sib npaug OEM daim ntawv teev nqi ntawm Cisco, Arista, lossis Juniper. Qhov no qhia txog cov qauv paj, tsis zoo sib txawv -OEM pricing bundles brand premium, support contracts, and sellor lock-in economics into the unit cost.

Kev ntes yog kev txheeb xyuas qhov tseeb. Cov neeg muag khoom hloov pauv loj siv EEPROM-raws li kev txheeb xyuas module uas tuaj yeem tsis lees txais thib peb- tog transceivers tshwj tsis yog lawv ua ntej- programmed nrog cov neeg muag khoom- cov lej tshwj xeeb. Cisco txoj kev mus kom ze yog nruj tshwj xeeb; modules tsis nyob rau hauv lawv compatibility matrix tej zaum yuav ua rau "tsis txaus siab" ceeb toom los yog tsis kam mus txuas tag nrho.

Qhov no yog qhov kev xaiv tus neeg muag khoom tseem ceeb. Ib tug thib peb -tus neeg muag khoom module uas tsis tuaj yeem ua EEPROM customization yog muag koj qhov kev twv txiaj. Ib tus uas muab lub platform- tshwj xeeb coding, ua ntej- xa khoom xa tuaj kuaj tawm tsam koj tus qauv hloov, thiab kev lees paub kev sib raug zoo yog muag koj cov kev daws teeb meem. Thoob plaws peb Cisco Nexus thiab Arista 7000-series kev xa tawm hauv ob xyoos dhau los, cov neeg siv khoom siv peb cov qauv ua ntej-cov ntaub ntawv pov thawj pom qhov txo qis ntawm 80% ntawm kev xa tawm- txog daim pib txhawb nqa piv rau lawv qhov kev yuav khoom thib peb yav dhau los yam tsis muaj kev siv lub platform.

Kev ntsuam xyuas cov neeg muab khoom:Nug cov ntaub ntawv ntawm lawv cov peev txheej EEPROM thiab seb lawv puas yuav sim tawm tsam koj qhov kev hloov pauv tshwj xeeb ua ntej xa khoom.

Qhov twg 200G QSFP56 Kev xa tawm ua rau kev lag luam zoo

AI/HPC pawg khiav InfiniBand HDR

InfiniBand HDR tus qauv ntawm 200Gbps, uaQSFP56 SR4 multimode transceiverslub neej ntawd kev sib txuas ntawm NVIDIA ConnectX-6 adapters thiab Quantum keyboards.

Kab laug sab-Leaf Data Centers tsoo 100G Saturation

65% kev siv nruab nrab lossis 85% kev siv lub ncov ntawm nplooj - mus rau - txha nraub qaum- cov no yog qhov chaw pib qhov twg latency jitter pib tshwm hauv daim ntawv thov saib xyuas. Hauv qab no cov lej, 200G yog them rau headroom koj yuav tsis siv. Saum toj no lawv, cov lej txawj tej yam ntxiv ua ncaj nraim. Rau cov koom haum tseem khiav 10G lossis 25G ntawm ntug, pebkauj ruam -los ntawm - kauj ruam qhia kev tsiv teb tsaws chaw networknpog cov theem mus kom ze uas txo qis kev cuam tshuam.

A 32-chaw nres nkoj hloov chaw khiav 200G QSFP56 SR4 xa 6.4 Tbps aggregate peev- lub ntsiab lus ceev rau cov koom haum uas nws txoj kev loj hlob tsis tau pom zoo 400G thermal overhead. QSFP-DD modules rub 12–15W txhua qhov raws li IEEE 802.3ck specifications, kwv yees li peb npaug ntawm 200G lub hnab ntawv lub zog, uas hloov pauv qhov sib npaug ntawm ib qho txias txias.

200G vs . 400G Kev Txiav Txim

Ntawm cov neeg siv cov ntaub ntawv peb tau ua haujlwm nrog rau qhov kev txiav txim siab no dhau 18 lub hlis dhau los, ib qho qauv tshwm sim: cov koom haum nrog cov kev npaj tsim kho tshiab nyob rau hauv 18 lub hlis thiab kev loj hlob ntawm 40% ib xyoos ib zaug tau xaiv QSFP-DD platforms populated nrog QSFP56 modules{{5}rov qab-chaw nres nkoj hloov dua siab tshiab rau ob qho tib si. Yog xav paub ntxiv txog kev sib piv ntawm cov qauv no, saib pebQSFP28 vs QSFP-DD cov lus qhia.

Rau kev rov ua dua tshiab 3+ xyoo tawm, kev xa tawm ib leeg 200G feem ntau muab TCO zoo dua. 400G ecosystem tus nqi hwm tus nqi tseem tsis tau ua tiav tag nrho, thiab koj tsis them nyiaj rau lub peev xwm koj yuav tsis qhib rau xyoo. Peb phau ntawv qhia txog 100G-rau-400G kev npaj kev tsiv teb tsaws chaw npog cov kev teeb tsa kev sib cais uas ua rau qhov kev hloov pauv no yooj yim dua.

Cov Kev Ua Haujlwm Tsis Ua Haujlwm Uas Tsis Ua Rau Hauv Cov Ntaub Ntawv

MPO Cable Polarity

Rau 200G SR4 transceiver- mus rau - kev sib txuas ntawm transceiver, Hom B polarity cables -key- mus txog qhov tseem ceeb - nce kev taw qhia - yog qhov yuav tsum tau ua. Hom A cables lub cev txuas tab sis tsim Tx- mus rau -Tx daim ntawv qhia uas lav qhov tsis ua haujlwm txuas. Qhov no tau txhais nyob rau hauv TIA-568, tab sis nws catches pab pawg accustomed rau duplex LC kev sib txuas uas polarity tswj yog yooj yim dua. Peb khaws daim ntawv txiav txim siab polarity hauv peb cov peev txheej tshwj xeeb vim tias lo lus nug no tuaj txog ze li txhua qhov kev xa tawm SR4.

FEC Configuration Mismatch

Ob qhov kawg ntawm 200G txuas yuav tsum pom zoo rau FEC teeb tsa-enabled tiv thaiv neeg tsis taus, thiab hom FEC tshwj xeeb (RS-FEC vs. FC-FEC). Kev tsis sib haum xeeb tsis cuam tshuam qhov yuam kev; qhov txuas tsuas ua tsis tau rau kev cob qhia. Peb taug qab ntau-hnub kev daws teeb meem lub voj voog ntawm cov neeg siv kev pabcuam nyiaj txiag kev xa mus rau qhov teeb meem tiag tiag no- ib qho kawg tau teeb tsa rau KP4 FEC, lwm qhov muaj FEC xiam oob qhab tag nrho. Cov tsos mob yog qhov sib txuas sib txuas- tom qab los ntawm kev ua tsis tiav tam sim. Tsis muaj dab tsi hauv cov cav taw qhia ncaj qha ntawm FEC kom txog rau thaum peb pib sib piv cov kab teeb tsa los ntawm kab.

Contamination Sensitivity

PAM4 lub suab nrov txo qis txhais tau hais tias cov qauv kev sib txuas huv huv uas dhau ntawm 100G yuav tsis txaus ntawm 200G. Insertion poob siab tshaj 1.5dB- feem ntau tshwm sim los ntawm kev sib kis tsis pom qhov liab qab - qhov muag tshuaj xyuas - tuaj yeem ua rau CRC tsis raug. IEC 61300-3-35 Cov qauv kev tu chav B yuav tsis yog-kev sib tham tsis yog qhov zoo tshaj{14}} xyaum. Rau luv luv- ncav cuag khib-rau-rack kev sib txuas qhov twg fiber tu tsis siv tau,direct txuas tooj liab cablestshem tawm qhov kev txhawj xeeb ntawm kev kis kab mob optical nkaus.
