Tsis ntev los no, IPEC (International Optoelectronic Commission) tau tshaj tawm cov kev lag luam thawj "100 Gbit / s / Lane-based 100 Gbit / s thiab 400 Gbit / s PAM4 Optical Module Test Specifications" (tom qab no hu ua "Test Specifications"), qhov kev sim Cov lus qhia tshwj xeeb los ntawm Pawg IPEC xeem, nrog kev koom tes ntawm ntau lub koom haum xws li Tuam Tshoj Academy of Information thiab Communications Technology, Accelerator, Huawei, Source, ZTE, YOFC, thiab lwm yam, nws lub hom phiaj los muab lub hauv paus xeem rau kev hloov pauv ntawm data center networks rau 400GE thiab pab ntau optical module manufacturers hauv kev lag luam saw. thiab nws cov neeg siv khoom txheeb xyuas cov teeb meem sib cuam tshuam thiab kev pheej hmoo ua ntej, thiab ua kom cov txheej txheem ntawm kev lag luam loj siv.
Nyob rau hauv xyoo tas los no, cov ntaub ntawv chaw lag luam tau txuas ntxiv kom muaj kev loj hlob sai. Ib tug loj tus naj npawb ntawm cov tshiab thiab reconstructed cov ntaub ntawv chaw tau txhawb lub lag luam xav tau rau optical modules, thiab lub lag luam nplai tau txuas ntxiv mus. Tus nqi ntawm optical modules siv nyob rau hauv cov ntaub ntawv chaw yog evolving los ntawm 100G mus rau 400G. Raws li kev soj ntsuam ntawm lub koom haum tshawb fawb kev lag luam LightCounting, cov tuam txhab kev pabcuam huab thiab cov chaw loj cov ntaub ntawv (DCs) yog thawj zaug pib hloov mus rau 400G, thiab lawv tau pib siv lawv hauv 2019. 400G yuav tsum ua tus thawj tswj hwm cov ntaub ntawv chaw lag luam los ntawm 2023.
Hauv 400GE optical modules tam sim no, 4 * 106Gbps PAM4 (400G-DR4, FR4, LR4) yog siv rau ntawm qhov chaw nres nkoj kho qhov muag kom paub txog 400G teeb liab kis, thiab 8 * 53Gbps PAM4 lossis 4 * 106Gbps PAM4 yog siv rau ntawm qhov chaw nres nkoj hluav taws xob. sab. Cov teeb liab hluav taws xob, hauv daim ntawv ntawm OSFP lossis QSFP-DD. Hauv kev sib piv, QSFP-DD muaj cov pob me me (zoo ib yam li QSFP28 pob ntawm ib txwm 100G optical modules) thiab yog qhov tsim nyog rau cov ntaub ntawv hauv chaw siv.
400GE optical modules, raws li cov khoom siv tseem ceeb rau kev sib tshuam ntawm kev sib txuas ntawm cov khoom siv kho qhov muag hauv cov ntaub ntawv chaw uas yuav tsum tau ua lag luam loj, xav kom kev lag luam koom ua ke tsim lub platform qhib rau kev txheeb xyuas dav. Vim li no, IPEC International Optoelectronics Committee tau tshaj tawm cov txheej txheem kev ua haujlwm sib cuam tshuam rau 400G Ethernet optical modules nyob rau lub Plaub Hlis 2021, aiming los tsim ib qho qhib kev sib koom tes platform rau 400GE los ua lag luam thiab paub tab; txhawm rau txhawb cov txheej txheem tshawb fawb ntawm lub platform qhib, nyob rau lub Cuaj Hli ntawm tib lub xyoo, IPEC thiab ntau tus tswv cuab koom ua ke tau ua kom pom 400GE optical module interoperability test Demo raws li IPEC xeem pab pawg tus kheej tsim kev sim platform ntawm Shenzhen Optical. Expo; Lub sijhawm no, IPEC tau tshaj tawm qhov kev xeem tshwj xeeb, uas yog kev lag luam thawj 400GE optical module. Tus qauv specification ntawm module interoperability xeem cia siab yuav muab ib tug haum haum rau cov kev lag luam saw los txhim kho thiab optimize lub interoperability kev ua tau zoo, thiaj li mus ua kom lub mature thiab loj-scale lag luam xa mus rau 400GE kev lag luam saw.
