Hauv kev sib txuas kho qhov muag fiber ntau, optical fiber transceivers yog ib qho ntawm cov khoom siv kho qhov muag tsis tseem ceeb. Fiber optic transceivers tuaj yeem raug cais raws li ntim, cov ntaub ntawv tus nqi, wavelength, thiab lwm yam.
Feem ntau siv optical fiber transceivers yog SFP, SFP +, XFP, thiab QSFP. Ntawm lawv, SFP + thiab XFP yog ob qho tib si 10G optical modules, tab sis SFP + modules tau tuav lub lag luam tseem ceeb ntawm 10G optical modules. Yog li dab tsi yog qhov txawv ntawm XFP thiab SFP +?
XFP transceiver module
XFP yog qhov kub-swappable fiber optic transceiver uas ua raws li XFP MSA raws tu qauv. XFP feem ntau yog siv hauv 10G bps SONET / SDH, Fiber Channel, Gigabit Ethernet, 10 Gigabit Ethernet thiab lwm yam kev siv, suav nrog CWDM thiab DWDM txuas. Piv nrog rau lwm yam 10G fiber optic transceivers, XFP muaj qhov me me thiab qis zog noj.
SFP + transceiver module
SFP + tshwm tom qab XFP thiab tseem yog qhov kub-swappable optical fiber transceiver. Tab sis SFP + qhov loj me me dua XFP. SFP + txhawb cov ntaub ntawv tus nqi txog 10G. Xws li 8G Fiber Channel, 10G Ethernet thiab OTU2 optical kis tau tus mob network qauv
XFP vs SFP +, qhov txawv yog dab tsi? Thaum ob lub modules feem ntau yog siv hauv 10G fiber optic tes hauj lwm, 10G XFP transceivers txawv ntawm 10G SFP + fiber ntau hauv qee qhov tshwj xeeb. Cia peb saib cov ntsiab lus ntawm daim duab hauv qab no.

Los ntawm kev sib piv XFP rau SFP +, nws yog qhov tseeb tias SFP + muaj qee qhov zoo dua XFP: 10G SFP + optics siv qhov chaw tsawg dua 10G XFP modules thiab tseem ua kom muaj qhov chaw nres nkoj ntau dua. Qhov no yog vim hais tias SFP + transceiver khaws ntau circuitry ntawm lub motherboard dua li hauv nws - nws offloads ib co functions rau motherboard, nrog rau cov teeb liab modulation functions, MAC, CDR thiab EDC. Tsis tas li ntawd, XFP thev naus laus zis tseem laus dua tab sis kim dua, yog vim li cas 10G SFP + modules tau txais kev lag luam ntau dua.
