Cov Lus Nquag Nug
Kuv puas tuaj yeem siv Ethernet Transceiver rau cov channel fiber ntau?
Tsis tau. Thaum tsim cov yam ntxwv sib xws (ob qho tib si siv SFP + piv txwv), Ethernet thiab Fiber ntau cov kev cai, sijhawm sijhawm, thiab firmware coding. Cov khoom siv yuav tsis lees txais kev hloov pauv transceiver rau cov kev cai lij choj tsis muaj tseeb, thiab txawm tias nws tsis ua li cas, qhov tsis sib haum teeb meem yuav tiv thaiv kev lag luam sib txuas.
Puas yog 10G SFP + ua haujlwm hauv 25G SFP28 chaw nres nkoj?
Lub cev yog, tab sis tsuas yog koj tswj hwm qhov chaw nres nkoj ceev rau 10G hom. Feem ntau 25g {- Cov chaw nres nkoj muaj peev xwm tsis pib {}}}}}}}}}}}}} Txoj Kev Ncaws Pob "tshwj tsis yog qhov chaw nres nkoj nrawm tau teeb tsa rau 10G.
Yuav muaj dab tsi tshwm sim yog tias FEC chaw tsis phim rau 100g txuas?
Qhov txuas yuav tsim tab sis pom cov nqi yuam kev siab (CRC yuam kev) lossis swb stermittently nyob rau hauv load. Pam4 transceivers ntawm 400g feem ntau suav nrog ua- hauv fec, xav tau host- sab fec kom tsis taus. Nrz transceiversivers ntawm 25g / 100g xav tau rs - fec enabled ntawm ob qho kev ua haujlwm rau kev ua haujlwm txhim khu kev qha dhau ntawm kev ncua.
Vim li cas kuv txoj kev hloov pauv tau qhia "tsis txhawb nqa" ntawm kuv tus hloov?
Qhov no feem ntau qhia cov neeg muag khoom coding tsis sib xws. Lub pob hluav taws xob xa cov ntaub ntawv ESPROM rau cov neeg muag khoom -}} speccection cov cim. Thib peb-} kev hloov tog tog neeg yuav tsum tau tshaj coding rau koj cov neeg muag khoom tshwj xeeb. Qee qhov hloov chaw tso cai tawm ntawm cov lus qhia kev teeb tsa no, tab sis qhov no yuav tsis muaj kev cog lus pab txhawb.
Kuv puas tuaj yeem sib xyaw ib qho - hom thiab multimode transceivers?
No. Ib Leeg - hom waverength) thiab xav tau ib leeg} hom transceivers, thaum muaj kev sib tshuam ntau. Lub cev optics, pob nyiaj hluav taws xob, thiab cov yam ntxwv sib kis tau sib txuam. Siv cov hom lus tsis haum rau kev sib txuas ua haujlwm tsis ua haujlwm.
Puas yuav tsum tau transi transceivers yuav tsum tau zoo ib yam ntawm ob qho kawg?
Tsis muaj {- qhov tseeb lawv yuav tsum sib txawv. Bidi Transceivers Siv cov sib txawv xa thiab tau txais wavelengths rau ib fiber ntau. Ib sab kis tau 1270nM thiab tau txais 1330nm, thaum lwm tus ua rov qab. Siv cov kev sib tw Bidi ntawm ob qho kawg ua ob qho tib si xa thiab tau txais tib lub wavelengths, tiv thaiv kev sib txuas lus.
The relationship between transceiver types and network protocols involves matching physical form factors, electrical signaling rates, encoding schemes, and vendor-specific coding requirements. Nkag siab txog cov nyiaj txiag no {2 2}} los ntawm cov kev xaiv nrawm rau kev txhim kho network tsim thiab muaj kev sib raug zoo tshwm sim. Raws li networks evolve mus rau 800g ethernet, thiab connerent plugargables specifications, thiab cov kev cai ua kom tiav raws li cov qauv txheej txheem thiab cov ntsiab lus siv.
