Tsis yog. Cov qauv siv tshuab thiab hluav taws xob sib txawv, thiab module keying yog npaj los tiv thaiv kev nkag mus rau hauv qhov chaw nres nkoj tsis ncaj ncees lawm hauv ob qho tib si.
Peb puas yuav tsum tos 1.6T es tsis txhob siv 800G?
Tos tsuas yog tias tam sim no muaj peev xwm txaus thiab cov txiaj ntsig xav tau tshaj qhov kev ncua thiab kev tsim nyog rau kev siv zog. Yog tias xav tau bandwidth tam sim no thiab 800G ecosystem ua tau raws li daim ntawv thov, kev siv tau siv tau 800G thaum tsim nyog 1.6T hauv chav kuaj yog qhov qis dua - kev pheej hmoo ua ntu zus.
Puas yog LPO ua haujlwm hauv txhua qhov OSFP hloov?
Tsis yog. Linear optics nyob ntawm ntau yam ntawm tus tswv tsev hluav taws xob interface thiab yuav tsum tau qhia meej platform thiab module tsim nyog. Daim ntawv-factor compatibility tsim tsis muaj dab tsi txog LPO kev txhawb nqa.
Xaus: Tsim lub Matrix, Tsis yog Huab Cua
Qhov tseem ceeb tshaj plaws OSFP txoj hauv kev tsis yog cov npe ntawm cov hnub kwv yees. Nws yog qhov txuas -los ntawm -link matrix. Rau txhua qhov kev sib txuas hauv lub network, sau qhov xav tau ceev, ncav cuag, hom connector, tus tswv txoj kab tus nqi, module fais fab, txwv cua txias, breakout hom, tsim nyog raws li txoj cai thiab lub hom phiaj xa tawm hnub. Sau nws los ntawm cov ntaub ntawv muag khoom thiab koj tus kheej cov txiaj ntsig tsis yog los ntawm cov khoom lag luam.
- ASIC- lub nti hloov pauv uas txiav cov kab hluav taws xob ntawm tus tswv tsev.
- SerDes- cov serializer/deserializer circuits uas teeb tsa qhov ua tiav tau rau - txoj kab.
- CMIS- Common Management Interface Specification, OIF- tuav tswj kev sib txuas ntawm tus tswv tsev thiab pluggable module.
- FEC- rov kho qhov yuam kev; ua ntej-FEC thiab tshaj tawm-FEC tus nqi yuam kev yog ob tus lej uas piav qhia txog kev sib txuas tiag tiag.
- MPO- ntau-fiber connector tsev neeg siv rau parallel optics thiab breakout cabling.
- DCI- data center interconnect, feem ntau ntev dua - mus txog kev sib txuas ntawm cov chaw.
- AEC- active hluav taws xob cable, ib tug powered tooj liab lwm txoj rau optics nyob rau hauv luv luv.
- Channel poob nyiaj txiag- tag nrho cov hluav taws xob poob ntawm lub rooj tsavxwm thiab cov khoom sib txuas yuav haus ua ntej lub module tsis tuaj yeem rov qab tau cov teeb liab.
