1. Dab tsi yog qhov transceiver module?
Transceiver modules, raws li lub npe qhia, yog bidirectional, thiab SFP kuj yog ib qho ntawm lawv.Lo lus "transceiver" yog ua ke ntawm "transmitter" thiab "receiver".Yog li ntawd, nws muaj peev xwm ua tau raws li ib tug transmitter thiab ib tug receiver los tsim kev sib txuas lus ntawm txawv pab kiag li lawm.Kev sib raug zoo rau lub module yog qhov kawg hu ua, nyob rau hauv uas lub transceiver module tuaj yeem muab tso rau.SFP modules yuav piav qhia ntau ntxiv hauv tshooj hauv qab no.
1.1 SFP yog dab tsi?
SFP yog luv luv rau Daim Ntawv Me Me-Qhov Pluggable.SFP yog tus qauv transceiver module.SFP modules tuaj yeem muab Gbit / s ceev kev sib txuas rau tes hauj lwm thiab txhawb nqa multimode thiab singlemode fibers.Hom interface feem ntau yog LC.Visually, cov hom fiber ntau txuas tuaj yeem raug txheeb xyuas los ntawm cov xim ntawm SFP's rub tab, raws li qhia hauv daim duab B. Lub nplhaib rub xiav feem ntau txhais tau hais tias ib hom kab cable, thiab lub nplhaib rub txhais tau hais tias ntau hom cable.Muaj peb hom SFP modules cais raws li kev sib kis ceev: SFP, SFP +, SFP28.
1.2 Qhov txawv ntawm QSFP yog dab tsi?
QSFP stands rau "Quad Form-factor Pluggable".QSFP tuaj yeem tuav plaub qhov sib txawv.Zoo li SFP, ob qho tib si ib hom thiab ntau hom fibers tuaj yeem txuas nrog.Txhua channel tuaj yeem xa cov ntaub ntawv tus nqi mus txog 1.25 Gbit / s.Yog li, tag nrho cov ntaub ntawv tus nqi tuaj yeem nce mus txog 4.3 Gbit / s.Thaum siv QSFP + modules, plaub txoj kev kuj tseem tuaj yeem muab ntim.Yog li, cov ntaub ntawv tus nqi tuaj yeem nce mus txog 40 Gbit / s.
