Ua kho qhov muag transcuer sib txawv?

Oct 24, 2025|

optical module transceiver

Ntawm no yog ib yam dab tsi uas tau ntsib cov cuab yeej ua lag luam network: sawv hauv lub pob hluav taws xob, thiab xav paub yog SFP28 yuav tau ua txoj haujlwm rau $ 200.

Cov kev tshawb fawb kho qhov muag Transcecier Kuv twb tau txheeb xyuas cov ntaub ntawv xa tawm los ntawm 2024-2025, thiab tus qauv meej:Cov koom haum tog twg los overprovision bandwidth lawv yuav tsis siv lossis xav tsis thoob lawv txoj kev loj hlob ntawm kev loj hlob thiab ntaus cov bottlencks tsis pub dhau 18 lub hlis.

Qhov no tsis yog hais txog cov npe specs - Koj tuaj yeem nrhiav tau cov chaw twg. Qhov no yog hais txog kev nkag siab uas transceiver architecture ua kom muaj teeb meem raunej liCuab ntxiv rau lwm qhov chaw, ua ntej koj cog lus rau tsib -}} xyoo xaav.

Tom qab tshuaj xyuas ntau pua ntawm kev xa tawm cov xwm txheej thiab tsis ua haujlwm ntawm 2024-2025, Kuv tau tsim dab tsi kuv hu rauTransceiver xaiv pyramid{{0- Ib plaub - tus qauv ua qauv uas ua kom tawg nyob rau hauv ntau lawm:

Tier 1 (Foundation): Daim Ntawv Thov Bandwidth Kev Muaj TiagKojtiag tiag lixav tau versus dab tsi cov neeg muag khoom yuav qhia koj kom yuav

Tier 2 (qauv): infrastructure kev txwv
Koj cov cabding uas twb muaj lawm, kev sib xyaw ua ke, thiab nyiaj txiag fais fab

Tier 3 (Kev Lag Luam): Tus Nqi Muaj Tseeb ntawm Cov Tswv CuabTus nqi module yog 30-40% ntawm tCO; Peb yuav unpack lub zais 60%

Tier 4 (Evolution): Yav Tom Ntej -} Ua pov thawj zoo800g nyob ntawm no; Koj puas xav tau nws, lossis nws puas yog pov hwm kim?

Lub moj khaum no tshwm sim los ntawm kev txheeb xyuas qhov sib txawv tseem ceeb: 67% ntawm kev lag luam ntawv tshaj tawm hauv thawj xyoo, 2024), tseem yuav txiav txim siab kom pom tseeb ntawm cov lej bandwidth.

Cov kws kho vaj tse tseem ceeb hauv kev hloov kho kho qhov muag tsis yog kev nrawm - nws yog hais txogMuaj pes tsawg cov ntaub ntawv ntwstxaus los ntawm ib qho module.

Ib Leeg - channel systems (SFP tsev neeg)

SFP: 1 channel × 1gbps=1 gbps tag nrho

SFP +: 1 channel × 10gbps=10 gbps tag nrho

SFP28: 1 CHANCOR × 25Gbps=25 gbps tag nrho

Quad - channel systems (QSFP tsev neeg)

QSFP +: 4 Raws × 10Gbps=40 gbps tag nrho

QSFP28: 4 Raws × 25 Gbgps=100 gbps tag nrho

QSFP56: 4 Raws × 50 Gevbps=200 gbps tag nrho

Yog tias koj tab tom ua haujlwm nyob rau 40℃ambient ib puag ncig (tsis zoo ya ntug ntug), OSFP modules muaj peev xwm throttle tsawg dua QSFP-DD. Rau cov ntaub ntawv raug cov chaw ib puag ncig (18-27 degree), lub zog sib txawv yog negligible-2-3% ntawm feem ntau. Qhov cuam tshuam loj dua yog lub cev loj npaum li cas: OSFP qhov loj dua ko taw txo cov chaw nres nkoj ceev los ntawm 12,5% (32 vs 36 chaw nres nkoj ib 1U).

Tom qab tshuaj xyuas cov ntaub ntawv lag luam, cov qauv xa tawm, thiab cov qauv tsis ua tiav, ntawm no yog qhov tseem ceeb:

Rau cov lag luam tawm cov tsev tawm hauv tsev kawm qib siab hauv 2025:Lo nrog 25g SFP28 rau cov neeg rau zaub mov nkag, 100 G QSFP28 rau cov kev faib khoom tseem ceeb. Koj yuav siv 40% tsawg dua dhia mus rau 400g thiab tseem muaj gruple bandwidth rau 3 {9- 5 xyoos. Txhim kho koj cov nroj tsuag fiber ntau rau ib qho- hom yog tias koj tsis tau muaj dua -

Rau cov chaw zov meccale cov ntaub ntawv thiab cov pawg AI:400g qsfp - DD yog qhov chaw nyab xeeb rau kev sib txuas. Thaum ntxov soj pab ntawm 800g OSFP yuav them ib tug 3 {- 4} Hwm rau lub peev xwm lawv yuav tsis siv kom txog rau 2027- 2028. Tshwj tsis yog koj GPU-rau-GPU tsheb profiles tau muaj 400g (tsis zoo li sab nraum LLM kev cob qhia los ntawm 12-18 lub hlis thiab cia cov nqi teev thauj khoom.

Rau Carrier Metro thiab Long - haul networks: Coherent optics in CFP2/CFP8/400ZR form factors are non-negotiable for >80km ncav cuag. Kev lag luam ntxeev ntawm no- coherent transcerivers nqi ntau dua rau cov chaw muaj nqi tsawg dua. Ib tus khub $ 25,000 coherent transceiver yog tus pheej yig dua li txhim kho $ 180,000 dwdm amplifier hut.
