FAQ Txog400G QSFP-DD DR4 Optical Transceiver
Q: Cov qauv no puas ua haujlwm nrog kuv lub Cisco lossis Arista hloov?
A: Yog. Nws ua haujlwm tawm - ntawm - lub - lub thawv nrog rau feem ntau lub lag luam hloov. Txhawm rau tshem tawm cov lus ceeb toom "tsis txhawb nqa transceiver", peb muab EEPROM coding pub dawb rau Cisco, Arista, Juniper, thiab lwm lub platforms-tsuas yog qhia rau peb paub koj tus qauv hloov thaum xaj.
Q: Tus nqi piv rau hom npe li cas -npe lwm txoj?
A: Cia siab tias 60-80% kev txuag nyiaj piv rau OEM- cov khoom sib npaug. Peb siv cov thev naus laus zis zoo ib yam Silicon Photonics thiab Broadcom DSP chips-tus nqi sib txawv los ntawm kev tshem tawm cov cim npe, tsis txiav qhov zoo.
Q: Dab tsi yog them raws li warranty?
A: 3-xyoo them rau qhov tsis xws luag thiab teeb meem kev ua haujlwm, ntxiv rau 30-hnub nyiaj rov qab lav. Txuas ntxiv 5-xyoo kev xaiv muaj rau kev xa khoom lag luam.
Q: Puas muaj qhov kev txiav txim yam tsawg kawg nkaus? Kuv tuaj yeem tau txais nws sai npaum li cas?
A: Tsis muaj MOQ- xaj txawm tias ib chav tsev rau kev ntsuas. Hauv -cov khoom xa tuaj hauv 1-3 hnub ua haujlwm. Cov nqi luv nqi pib ntawm 100+ units.
Q: DR4 vs FR4 vs LR4-uas kuv xav tau?
A: Nws nyob ntawm qhov deb. DR4 npog txog li 500m siv 4 parallel fibers -zoo tshaj rau intra-datacenter links. FR4 ncav cuag 2km ntawm 2 fibers ntawm wavelength multiplexing. LR4 txuas ntxiv mus rau 10km rau cov pob txha hauv tsev kawm ntawv. Rau feem ntau khib-rau- khib lossis kab-rau- kab sib txuas, DR4 muab tus nqi qis tshaj plaws thiab lub zog kos.
Q: Kuv puas tuaj yeem txuas qhov no rau kuv cov khoom siv 100G uas twb muaj lawm?
A: Yog lawm. Siv hom kev sib cais los faib ib qho 400G chaw nres nkoj rau hauv plaub qhov kev sib txuas 100G ntawm MPO-rau-LC cable. Qhov no tso cai rau koj hloov kho tus txha nraub qaum mus rau 400G thaum khaws cov nplooj hloov pauv ntawm 100G- tsis tas yuav hloov kho forklift.
Q: Dab tsi ua rau QSFP-DD txawv ntawm QSFP28?
A: Muab ob npaug rau txoj kab hluav taws xob-8 piv rau 4-ua kom 400G hauv qhov zoo sib xws. Lub connector yog rov qab sib xws, yog li koj tseem tuaj yeem siv QSFP28 modules hauv DD chaw nres nkoj ntawm qis dua.
Q: Vim li cas PAM4 tsis siv NRZ signaling?
A: PAM4 ntim 2 khoom rau ib lub cim (vs 1 me ntsis hauv NRZ), ua ob npaug ntawm kev xa tawm yam tsis tau muab ob npaug rau qhov kev taw qhia zaus. Qhov no ua rau cov khoom siv hluav taws xob pheej yig thaum ntaus 400G ceev. Lub built-hauv 7nm DSP ua haujlwm cov teeb liab ntxiv ntawm qis dua 10W.
Q: Kuv yuav nruab nws li cas?
A: Kub- sib pauv tus phooj ywg- tsis tas yuav muaj sijhawm poob. Ntxuav cov fiber ntau, xaub lub module kom txog thaum nws nyem, txuas koj MPO-12 cable, ua tiav. Auto-negotiation lis lwm tus. Rau hom kev tawg, teeb tsa qhov chaw nres nkoj li "4x100G" hauv koj qhov hloov CLI.
Q: Txuas qhov yuam kev lossis teeb liab tsis muaj zog -Kuv yuav tsum kuaj dab tsi?
A: Pib nrog cov hauv paus ntsiab lus: cov khoom siv qias neeg (ntxuav nrog lint- cov ntaub so dawb), hom fiber ntau tsis raug (yuav tsum yog tib hom -} hom), lossis ntau lub vojvoog khoov. Xyuas kom tseeb tias qhov txuas yog qis dua 500m thiab koj lub firmware hloov pauv tau raws li qhov tsawg kawg nkaus ntawm peb daim ntawv teev npe sib raug. Tshawb xyuas Tx/Rx lub zog ntawm CLI- nyeem tsis zoo taw tes rau cov teeb meem cable lossis connector.
