(Small Form-factor Pluggable) Ib qho me me transceiver uas ntsaws rau hauv SFP chaw nres nkoj ntawm lub network hloov thiab txuas rau Fiber Channel thiab Gigabit Ethernet (GbE) optical fiber cables ntawm lwm qhov kawg. Superseding GBIC transceiver, SFP modules kuj hu ua "mini-GBIC" vim lawv qhov me me. Los ntawm kev xaiv qhov tsim nyog SFP module, tib qhov chaw nres nkoj hluav taws xob ntawm qhov hloov pauv tuaj yeem txuas rau fibers ntawm ntau hom (multimode lossis singlemode) thiab qhov sib txawv wavelengths. Yog tias cov fiber ntau tau hloov kho, SFP module hloov.

Lub SFP hloov cov cim hluav taws xob serial rau serial optical signals thiab vice versa. SFP modules yog kub swappable thiab muaj ID thiab cov ntaub ntawv kaw lus rau kev hloov.

Combo SFP Chaw nres nkoj

Combo ports yog ua ke nrog Ethernet ports. Piv txwv li, yog tias ib qho SFP transceiver tau ntsaws rau hauv SFP chaw nres nkoj 24, ces Ethernet chaw nres nkoj 24 yog neeg xiam oob khab txawm tias lub cable txuas.

XFP thiab SFP + rau 10 Gigabits

Loj dua SFP, XFP transceivers yog thawj tus tswj 10 Gigabit Ethernet optical kab, vim tias SFP txhawb nqa txog li 4.25 Gbps. Tib qhov loj me me li SFP, SFP + tau qhia tom qab los tswj 10 Gbps tab sis xav tau ntau dua circuitry hauv lub party ntaus ntawv. Raws li qhov tshwm sim, SFP + cov chaw nres nkoj feem ntau pom muaj nyob rau hauv daim npav ntsaws rau cov servers thiab cov chaw lag luam hloov pauv. Saib transceiver thiab GBIC.

Lub neej yav tom ntej ntawm kev sib txuas lus tau tshwm sim niaj hnub no hauv daim ntawv ntawm fiber ntau optics. Ntau tus ISP thiab cov chaw muab kev sib txuas lus tau ceev nrooj sim siv, fiber ntau optics rau hauv, lossis qhov chaw, lawv cov tes hauj lwm uas twb muaj lawm.

JHA thev naus laus zis twb muaj cov thev naus laus zis no nyob rau hauv qhov chaw, thiab vim li ntawd tau muaj ib qho kev sib txuas siab tshaj plaws hauv Tebchaws Europe thiab Asmeskas.

Qhov zoo tshaj plaws ntawm fiber ntau optics yog nws cov kev saib xyuas dawb symetrical bandwidth muaj peev xwm thiab scalability. Fiber optic cables tuaj yeem txav tau cov ntaub ntawv ntau dua exponentially zoo dua li cov kab tooj liab.

Fiber optic cables yog ua los ntawm nyias strands ntawm iav thiab xa cov ntaub ntawv ntawm pulses ntawm lub teeb, uas yog hloov dua siab tshiab rau hauv hluav taws xob teeb liab. Txij li thaum lub teeb mus nrawm dua li hluav taws xob, cov ntaub ntawv txav nrawm dua li nrog lwm hom kab hluav taws xob.

Raws li cov fiber ntau optic cables yog ua los ntawm iav thiab tsis yog hlau, lawv tsis ua hluav taws xob thiab yog li tsis raug kev txom nyem los ntawm cov teeb liab degrading hluav taws xob cuam tshuam los ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob lossis teeb pom kev zoo.

Peb cov neeg siv khoom tau txais txiaj ntsig los ntawm peb qhov kev ua haujlwm tsis sib xws hauv lub network thiab cov kev daws teeb meem zoo rau lub suab | Internet | cov ntaub ntawv.

Kev koom tes nrog JHA ua kom koj tuaj yeem siv sijhawm ntau ntxiv rau kev loj hlob koj txoj kev lag luam thiab tsis muaj sijhawm txhawj xeeb txog koj lub network kev ua haujlwm.

Pom zoo cov kev daws teeb meem ntawm Metro Ethernet

Yog tias koj lub network suav nrog ntau qhov chaw, chaw nyob deb, chaw ua haujlwm hauv tsev lossis ib qho kev sib txuas ntawm kev lag luam-rau-kev lag luam, Metro Ethernet tuaj yeem ua rau koj lub network muaj kev nyab xeeb thiab, qhov tseem ceeb tshaj, ruaj ntseg.

JHA tuaj yeem muab koj txoj kev lag luam nrog cov kev cai daws teeb meem uas tso cai rau ntau qhov chaw lag luam hauv cov ntaub ntawv chaw nkag mus rau ib lub network ntiag tug ntawm ib qho ntawm lawv qhov chaw sib txuas.

Kuj tseem muaj lwm qhov kev daws teeb meem P2P Connectivity (Point-to-Point Connections for Data and Voice).
