Cov Lus Qhia Tshwj Xeeb ntawm Cisco SFP Transceivers
Cisco SFP transceivers yog tsim los hloov cov hluav taws xob cov cim hluav taws xob rau cov teeb liab txuas hluav taws xob uas feem ntau tswj hwm gigabit Ethernet, suav nrog cov channel fiber thiab SONET / SDH, nws muab txoj hauv kev muaj txiaj ntsig, txais cov qauv ntawm kev daws teeb meem hauv tsev kawm qib siab, hauv cov ntaub ntawv chaw, chaw loj hauv nroog, nplhaib sib txuas thiab khw cov vev xaib.
Ethernet converter nqa ntawm ib kawg mus rau lwm qhov kom cia ntau lub tshuab sib txawv xov kom raug sib txuas Ethernet cable. Qhov no zoo li no tau siv nyob rau hauv qhov zoo sib xws tsim ib zaug muaj ob peb lub koos pij tawj ua haujlwm nrog ntau hom thev naus laus zis. Ib qho ntxiv, cov kab hluav taws xob fiber ntau tuaj yeem tawm tsam los ntawm txhua yam ntawm cov khoom siv hluav taws xob, xov tooj ntawm tes thiab wireless ua ke uas feem ntau tsis nyiam nrog cov tsoos Ethernet, cov cuab yeej zoo li no tau poob lub teeb liab cuam tshuam. Nyob rau hauv cov ntaub ntawv no, raws li hloov mus rau hauv optical fiber Ethernet, vim nws muab lub nrawm nrawm thiab zoo heev. SFP yog los ntawm cov tswj hwm kev ruaj ntseg hauv hiav txwv lossis los ntawm IBM, txoj kev tsis txaus ntseeg, Siemens, xam / TYCO thiab Infineon Ntau qhov chaw tsis muaj peev xwm, qhov no yog lub ntsiab lus tseem ceeb ntawm cov tswj kev muag khoom network. SFP cov khoom lag luam sib txuas tau muaj cov kev zoo li hauv qab no:
1. Vim li cas ntawm qhov uas koj tuaj yeem ntxig, kho qhov muag fiber ntau, tseem tuaj yeem hloov kho ntawm qhov kawg ntu ntawm kev tsim daim npav.
2. Nws muaj peev xwm kom haum raws li txuas ntau lub txuas lossis kev sib xyaw ua ke LX SFP thiab SX.
3. Txij li thaum lub pob tawb ntawm SFP transceiver muab tso rau hauv PCB kom thiaj li lees txais cov lus teev tseg, nws tuaj yeem txo cov haujlwm ntxiv, thiaj li txo cov nqi. Raws li qhov tshwm sim, nws ua rau nws yooj yim dua kev hloov kho thiab hloov chaw.
4. Vim tias cov khoom siv kho qhov muag, SFP transceivers txhim kho kev ntseeg tau. Nws tso cai rau siv cov kub siab dua.
Cisco SFP yog qhov sib hloov hloov tau, ntxiv rau nws yoog raws, ntawm ntau cov haujlwm Cisco. Nws tuaj yeem siv nrog Cisco 1000BASE-TX, 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-EX, 1000BASE-ZX, lossis 1000BASE-BX10-D / U hauv chaw nres nkoj los ntawm cov chaw nres nkoj sib koom ua ke.
Cisco SFP modules yuav tsum txuas cov txheej txheem ib thooj rau lwm qhov, vim nws ua lub luag haujlwm tseem ceeb hauv kev lag luam cov ntaub ntawv siv tshuab.
SFP transceiver modules feem ntau kub-pluggable I / O cov khoom siv uas yooj yim tuaj yeem nkag mus rau hauv cov hlua khawm. Cov transceiver siv tau zoo txuas rau qhov hluav taws xob Circuitry ntawm qhov module mus rau tooj liab lossis network. Cov neeg siv tuaj yeem siv txhua qhov kev sib xyaw ntawm SFP transceiver modules uas Cisco transceiver ntaus ntawv pabcuam. Tib qho uas yuav tsum nco ntsoov nyob ntawm no yog tias txhua qhov chaw nres nkoj yuav tsum sib phim rau qhov ntev ntawm qhov xav tau ntawm lwm qhov kawg ntawm lub cable thiab tias cable yuav tsum tsis pub tshaj qhov txhawj xeeb cable ntev kom thiaj li muaj kev sib txuas lus zoo ib yam. Nws raug nquahu kom cov neeg siv siv SFP transceiver Cisco modules tsuas yog siv Cisco ntsuas. Txhua txhua Cisco SFP transceiver module pab Cisco zoo cim uas ua rau Cisco router lossis hloov pauv kom paub thiab lees paub tseeb tias transceiver module tau tshuaj xyuas thiab pom zoo los ntawm Cisco. Tam sim no kuv qhia SFP-10G-ZR tau tshaj Cisco pab kiag li hauv Fiberstore. nws yog pheej yig dua tuam txhab Cisco. SFP-10G55-80-CO series ib hom transceiver yog daim ntawv me me qauv pluggable module rau kev ua tiav cov ntaub ntawv kho qhov muag ntawm 10G. Tus hloov khoom siv no muaj cov haujlwm zoo ib yam nrog Cisco SFP-10G-ZR thiab nws muaj kev siv tau tag nrog Cisco. Nws yog nrog SFP + 20-pin txuas kom tso cai rau lub peev xwm kub.Qhov qauv no tau tsim rau ib hom fiber ntau thiab ua haujlwm ntawm lub zog nominal wavelength ntawm 1550 nm.
FOCC tau tsim nyob rau xyoo 2005, peb lub hom phiaj yog los muab cov khoom zoo fiber ntau rau lub ntsej muag, SFP ua kom sib haum, GBIC LAN thiab WAN tes hauj lwm thiab cov khoom lag luam muaj feem xyuam. FOCC ntseeg hais tias txoj hauv kev kom ua tiav yog dhau los ntawm kev ua tau zoo thiab kev pabcuam rau cov neeg siv khoom. Thiab tam sim no FOCC nyob rau hauv kev txiav txim rau cov qhua tuaj noj mov ntawm lawv cov neeg tuaj xyuas, nws koj xav paub ntau cov ntaub ntawv hais txog cov xov tooj hluav taws xob optical transceivers zoo siab txais tos tuaj saib peb FOCC.
