SFP optical module yog dab tsi?
SFP optical module yog cov khoom siv sib txuas uas hloov pauv gigabit hluav taws xob cov cim rau ua cov cim kho qhov muag. Nws yog qhov kev lag luam-tus qauv me thiab pluggable gigabit optical transceiver module uas tuaj yeem ntsaws rau hauv cov khoom siv hauv network xws li hloov chaw, cov hloov pauv, thiab cov hloov pauv tawm. SFP chaw nres nkoj yog siv los txuas cov kho qhov muag lossis tooj liab network cable rau cov ntaub ntawv xa tawm. Feem ntau peb tuaj yeem nrhiav nws hauv Ethernet keyboards, routers, firewalls thiab network interface phaib.
SFP chaw nres nkoj yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm SFP chaw nres nkoj yog rau cov teeb liab hloov dua siab tshiab thiab cov ntaub ntawv xa mus. Nws qhov chaw nres nkoj tau ua raws li IEEE 802.3ab tus qauv (xws li 1000BASE-T), thiab qhov siab tshaj plaws kis tau mus txog 1000 Mbps (SFP chaw nres nkoj ntawm tus hloov hloov txhawb nqa 100 / 1000Mbps).
SFP chaw nres nkoj nta
SFP qhov chaw nres nkoj yog qhov kub-hloov mus rau I / O interface (xa mus rau cov tswv yim / tso tawm interface), uas muaj qhov hloov tau yooj yim thiab haum rau ntau yam khoom, xws li 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-ZX lossis 1000BASE -BX10-D / U cov chaw nres nkoj tuaj yeem sib pauv tau, thiab SFP chaw nres nkoj rov qab tau tshaj, txhawb nqa 10/100 / 1000Mbps.
SFP chaw nres nkoj ntawm Gigabit hloov
SFP chaw nres nkoj ntawm gigabit hloov tuaj yeem siv los nthuav cov haujlwm hloov chaw ntawm txhua lub network los ntawm kev sib txuas ntau yam ntawm cov kho qhov muag (xws li ib hom thiab ntau hom fiber ntau) thiab cov tshuab dhia network (xws li Cat5e thiab Cat6), tab sis SFP chaw nres nkoj ntawm tus lej gigabit hloov SFP qhov kho qhov muag siv tau yuav tsum muab tso ua ntej siv, thiab tom qab ntawd siv cov khoom siv hluav taws xob dhia thiab cov neeg ua hauj lwm hauv lub network rau kev xa cov ntaub ntawv. Tag nrho cov qib kev hloov ntawm cov chaw ua lag luam tam sim no muaj tsawg kawg ob qhov SFP chaw nres nkoj, uas tuaj yeem siv los tsim lub nplhaib lossis lub hnub qub network cov topologies ntawm cov tuam tsev sib txawv, cov plag tsev lossis thaj chaw los ntawm kev sib txuas ntawm cov kho qhov muag thiab cov dhia network.
Cov txiaj ntsig zoo ntawm SFP optical module
Qhov ntim ntawm SFP optical module yog txo los ntawm ib nrab piv nrog qhov ntim ntawm GBIC optical module. Tus naj npawb ntawm SFP cov chaw nres nkoj ntawm tib lub vaj huam sib luag yuav yog ob npaug ntawm GBIC optical module. Tib qho SFP qhov kho qhov muag tau muaj qhov txuas thiab-ua si mini qhov kho qhov muag fiber ntau, uas ua raws cov ntaub ntawv Nrog rau qhov ntsuas qhov siab xav tau hauv nruab nrab, SFP optical modules yuav hloov GBIC optical module hauv cov chaw zov me nyuam yav tom ntej.
Nrov SFP cov kho qhov muag sib luag
Vim tias SFP optical module ntawm GLC-BX-D thiab GLC-BX-U yog cov muaj zog thiab nrhiav tom qab, cov ob hom ntawm cov khoos phis tawm tau txhawb nqa cov ntaub ntawv kho qhov muag, tso cai rau cov neeg siv saib xyuas kev ua haujlwm ntawm cov khoos phis tawj nyob rau hauv lub sijhawm, xws li nrhiav kev ntsuas kub, lub teeb tawm tso zis hluav taws xob, lub zog hluav taws xob nkag, laser bias tam sim no, transceiver fais fab mov voltage, thiab lwm yam.
Ntxiv rau, 1000BASE-BX10-D SFP optical module nrog qhov sib txawv ntawm 10km, GLC-BX40-D SFP optical module nrog qhov sib kis tau ntev txog 40km, thiab GLC-BX80-D SFP optical module nrog kis tau deb ntawm 80km tseem nrov ntawm cov neeg siv.
SFP kho qhov muag saum toj saud muaj plaub qhov zoo hauv qab no:
1. Txhawb kev sib hloov kub, uas tuaj yeem txo kev txhim kho, txij nkawm thiab tswj lub sijhawm;
2. Qhov chaw nres nkoj yog hloov tau;
3. Txuj kev tsim qauv txhim khu kev ntseeg tau;
4. Txhawb digital optical xyuas (DOM) muaj nuj nqi.
SFP optical module thov
1. Cov kab hluav taws xob luv-deb network
1000BASE-T SFP optical module txhawb 10/100/1000 kev hloov kho thiab Auto MDI / MDIX, thiab tuaj yeem siv nrog qeb 5 qhov tsis muaj kab thaiv ua haujlwm hauv lub network; kis nrug deb tuaj yeem ncav cuag 100m.
1000BASE-SX SFP optical module tau sib xws nrog IEEE 802.3z 1000BASE-SX tus qauv, thiab tuaj yeem siv rau hauv 50μm / 62.5μm multimode optical fiber txuas txuas nrog qhov siab tshaj plaws kis tau tus mob ntawm 550m.
2. Kev tiv thaiv network ntev-ntev
1000BASE-EX thiab 1000BASE-ZX SFP optical modules siv tau nrog tib hom kho qhov muag thiab tsim nyog rau kev xa xov hauv lub network ntev. Qhov kev sib kis deb ntawm 1000BASE-EX SFP optical modules tuaj yeem ncav cuag 40km, thiab kis tau deb ntawm 1000BASE-ZX SFP optical modules tuaj yeem ncav cuag 80km.
Nco tseg: Thaum ib hom fiber ntau (SMF) siv rau qhov chaw nyob ib ntus, kom tsis txhob muaj ntau dhau ntawm qhov tau txais, yuav tsum tau siv lub ntsej muag kho qhov muag.
Xaus
SFP chaw nres nkoj tuaj yeem txhawb nqa ob qho tib si SFP chaw nres nkoj hluav taws xob chaw nres nkoj thiab SFP optical chaw nres nkoj modules. Ob qho SFP qhov chaw nres nkoj thiab SFP cov kho qhov muag tau muaj qhov yooj thiab qhov yooj yim hauv kev siv thiab yog qhov kev daws teeb meem zoo tshaj plaws rau Gigabit Ethernet.
