Peb txhua tus paub tias ib txwm 100G optical modules siv 4 25G optical channels nyob rau hauv parallel lossis wavelength division multiplexing rau kev sib kis. Lub ntsiab kho qhov muag modules nyob rau hauv kev ua lag luam feem ntau yog 100G SR4 / CWDM4 / PSM4 / LR4 / ZR4, thiab lwm yam. Lub 100G ib leeg- wavelength optical module peb qhia rau koj hnub no siv ib leeg-wavelength 100G PAM4 modulation tshuab, uas tuaj yeem txo cov nqi ntau lawm thiab tau txais kev sib kis tau zoo dua.
1. Qhov txawv ntawm cov tsoos 100G optical modules thiab 100G ib leeg-wavelength optical modules
Cov tsoos 100G optical module siv 4x25G NRZ thev naus laus zis. Siv plaub txoj kev sib txuas lus ywj pheej thiab txais tos, 4 raws ntawm 25Gb / s cov ntaub ntawv hluav taws xob tuaj yeem hloov mus rau 4 raws ntawm LAN WDM optical signals, thiab tom qab ntawd lawv tau muab faib ua ib qho ntawm 100Gb / s optical kis tau tus mob. Thaum kawg tau txais, 100Gb/s optical input yog demultiplexed rau hauv 4-channel LAN WDM optical signals, uas yog tom qab ntawd hloov mus rau hauv 4-channel hluav taws xob cov ntaub ntawv tawm.
Tsis tas li ntawd, ib txwm siv 100G optical modules yuav tsum muaj kev ywj pheej xa tawm thiab tau txais cov khoom siv ntawm txhua qhov channel, uas tsis yog tsuas yog ua kom lub zog noj thiab chaw ua haujlwm ntawm qhov kho qhov muag module, tab sis kuj nce tus nqi. 100G ib leeg-wavelength kho qhov muag module hloov lub 4-channel 25Gbps NRZ teeb liab ntawm lub voj voog kawg rau hauv ib qho channel ntawm 53Gbps los ntawm kev ua DSP ntawm PAM nti los ntawm kev tsav tsheb txias electro-absorption modulated DFB laser (EML). Cov thev naus laus zis no txhim kho cov teeb liab sib kis tau zoo thiab txo cov xov tooj ntawm cov teeb liab raws li qhov xav tau piv rau NRZ modulation technology.
100G ib leeg-wavelength kho qhov muag module txais PSM4 kev sib txuas lus thev naus laus zis ntau dua, txo tus naj npawb ntawm kev xa khoom kho qhov muag thiab tau txais los ntawm 4 mus rau 1, uas tuaj yeem txo tus nqi ntau dua 40%. Txij li thaum 100G ib leeg-yoj tshuab txais ib leeg-channel PAM4 thev naus laus zis, qhov kev tsim kho tshiab no ua rau nws muaj peev xwm hloov kho 100G rau 4x100G (400G optical module) smoothly.
2. FOCC 100G Ib leeg-nqaj series khoom
FOCC 100G single-wavelength optical modules tam sim no suav nrog 100G QSFP28 DR1 / FR1 / LR1 / ER1. Lawv txhua tus tsim nyog rau 100Gb / s cov ntaub ntawv ceev ceev kev sib txuas lus siv ib leeg-hom optical fiber. Kev khiav hauj lwm wavelength yog 1310nm, thiab cov teeb liab kho qhov muag yog multiplexed rau ib hom optical fiber siv ib tug duplex LC connector. Cov khoom lag luam no yog tsim los nrog qhov ntev, kev sib txuas kho qhov muag / hluav taws xob, thiab cov kev kuaj mob digital interfaces raws li QSFP28 Multi-Source Agreement (MSA). 100G QSFP28 optical module muaj qhov sib txuas ntau tshaj plaws ntawm 40 mais ntawm ib hom OS2 optical fiber ntau thiab feem ntau yog siv hauv cov ntaub ntawv sib txuas, 100G Ethernet, kev lag luam tes hauj lwm, thiab lwm yam.
Raws li lub platform kev tshaj lij rau txhua yam khoom siv kho qhov muag thiab cov kev pabcuam, ETU-LINK tuaj yeem muab kev ruaj ntseg, txhim khu kev qha, raug nqi, txuag nqi, ib leeg-yoj 100G QSFP28 optical modules nrog hermetic (los yog non-hermetic) ntim cov kev daws teeb meem . Qhov no yog qhov kawg ntawm tsab xov xwm no. Yog tias koj xav paub ntau ntxiv txog cov khoom lag luam, koj tuaj yeem tawm cov lus lossis cov lus ntiag tug hauv qab no. Mus ntsib koj tom ntej kom paub ntau ntxiv!
