Tau txhais los ntawm pab pawg kev lag luam hauv xyoo 2002, XFP yog tus qauv rau cov neeg tos txais siv hauv cov khoos phis tawj loj thiab sib txuas lus hauv xov tooj uas siv kho qhov muag. XFP transceivers yog kub hloov chaw tau tsim rau 10G network daim ntaub ntawv xws li 10 Gigabit Ethernet, 10 Gbit / s Fiber Channel, synchronous optical networking (SONET) ntawm OC-192 tus nqi thiab lwm yam. Cov hauv qab no yog qee qhov tseem ceeb uas cov neeg lag luam yuav tsum paub txog XFP transceivers yog tias lawv nyob rau hauv kev ua lag luam rau lawv.
Tsim los ntawm XFP ntau qhov kev pom zoo (MSA) pab pawg, qhov tshwj xeeb ntawm XFP transceiver yog qhov kev pom zoo tsis raws cai ntawm ib pab pawg kev lag luam. Hauv lwm lo lus, nws tau lees paub los ntawm ntau tus neeg tsim qauv hauv kev lag luam es tsis yog "raug cai" pom zoo los ntawm tus qauv lub cev. Nws muaj ntau yam hloov tshiab rau qhov kev ntsuas no txij li nws tau tsim ua thawj zaug xyoo 2002.
XFP transceiver's interface rau lwm cov khoom siv hluav taws xob feem ntau hu ua XFI. Tsim los ntawm XFP MSA pab pawg, XFI hluav taws xob interface tshwj xeeb yog 10 Gbit / s nti-rau-chip hluav taws xob interface kev qhia tshwj xeeb uas tau txhais ua ib feem ntawm XFP MSA.
XFP transceivers tuaj yeem ua haujlwm ntawm ntau lub wavelengths suav nrog 850 nm, 1310 nm, thiab 1550 nm, thiab lwm yam Thiab ntawm cov ze-infrared wavelengths, cov cim qhia tuaj yeem kis tau nrog kev ntseeg siab thiab nyob deb ntawm ntev. Ntxiv rau, cov transceivers no tseem ua hauj lwm dhau ib qho yoj yoj thiab siv cov kev txawj ntau yam sib npaug.
XFP muaj ntau yam muaj ntau lub transmitter thiab txais hom, thiab muaj plaub yam tseem ceeb XFP transceivers, uas tso cai rau cov neeg siv khoom xaiv hom XFP transceiver uas lawv xav tau hauv lawv cov qauv. Cov khoom siv sib txuas ntawm XFP feem ntau yog 10GBASE-SR XFP transceivers uas muaj lub suab yoj ntawm 850 nm thiab qhov siab tshaj plaws kis tau tus mob mus txog 300 m, thiab 10GBASE-LR XFP transceivers uas muaj nthwv dej ntawm 1310 nm thiab qhov sib kis tau mus txog 10 km. Ob leeg 10GBASE-ER XFP transceivers thiab 10GBASE-ZR XFP transceivers siv ntau yam 1550nm, tab sis lawv hloov cov ntev sib txawv li 40 km thiab txog 80 km feem.
XFP transceivers yog loj dua ntawm SFP + transceivers (raws li qhia hauv daim duab hauv qab no), tab sis lawv nyob deb ntawm cov me me 10 Gbit / s cuam tshuam rau kev sib kis ntom ntom ntaws sib kis sib kis sib kis sib kis (DWDM). Ntxiv mus, ntau lub kho qhov muag txais yuav XFP transceivers txawm tias yuav tsum muaj kev sib kis ntev ntev.
Hauv kev xaus, XFP transceivers muaj kev hloov pauv thiab tuaj yeem muab cov neeg siv ntau txoj hauv kev ntawm cov qauv tsim. Nws yog txaus siab los ntawm cov neeg siv khoom uas tab tom tshawb rau cov khoom siv me me nrog yooj thiab lub zog. Tam sim no, muaj ntau yam XFP transceivers hauv khw. Ntawm lawv, Cisco XFP transceivers yog ib qho zoo tshaj plaws muag XFP transceivers.
