Tham Txog 2.5G Thiab 5G
Network tshuab yog tsim nrawm. Txhim kho nrog cov qauv, cov chaw zov me nyuam yuav tsum tau los txhim kho tas li, txij 10G txog 40G, 40 G txog 100G thiab txawm tias 100G rau 400G. Txawm li cas los xij, rau qee cov chaw lag luam me nrog cov chaw 1G, ncaj qha mus rau lub tebchaws ntawm 1G txog 10G yog me ntsis yoo mov. Puas muaj lwm cov lus qhia qeeb qeeb Ethernet los ua kom sib txawv ntawm 1G Ethernet thiab 10G Ethernet speeds? Cov lus teb yog Yes-2.5 Ethernet thiab 5G Ethernet. Tsab xov xwm no yuav tham txog 2.5G thiab 5G.
Lub cev (PHY) txheej xaib txuas ntawm IEEE 802.3bz yog raws li 10GBASE-T, tab sis ua hauj lwm ntawm ib qho kev qhia tsawg dua. Los ntawm kev txo cov teeb liab thawj zaug rau 1/4 lossis 1/2, qhov hloov tus nqi xa mus rau 2.5 los sis 5 Gbit / s, feem. Lub spectral bandwidth ntawm lub teeb liab yog kom haum, txo cov tseev ntawm cabling, kom 2.5GBASE-T thiab 5GBASE-T yuav deployed ntawm ib cable ntev ntawm 100 meters ntawm unshielded Cat5e cable thiab Cat6 cable, feem. Cov duab hauv qab no qhia txog kev sib piv ntawm cov kev yees twv nrog cov Ethernet technologies.
Raws li cov qauv 2.5G thiab 5G Ethernet tawm tom qab 10G Ethernet tus qauv, muaj kev tshuaj ntsuam xyuas rau lawv. Qeb no yuav tsom rau cov khoom siv thiab kev tshaj li ntawm 2.5G / 5G Ethernet qauv.
Thaum 2.5G Ethernet thiab 5G Ethernet cov qauv qhia tawm, ntau tus neeg tsis xav txog ntau ntau. Lawv hais tias:
5GBase-T thiab 5GBase-T ntau yuav siv rau wifi rollouts. Thiab lawv zoo nkauj heev rau enterprise wireless deployments.
10GbE tau txais pheej yig zoo nkauj. Muaj ntau cov qauv duab tshiab tam sim no muaj 10G NICs hauv lawv thiab tus nqi yuav zoo dua li $ 100 dhau los, uas tsis yog phem heev. Dab tsi 's ploj lawm yog ib pawg ntawm 10G tsev keyboards thiab routers.
Raws li qhov muaj, tus 10G muaj 2 qauv tawm thaum lub 2.5G thiab 5G yog ob qho "los sai sai". Vim lub economies ntawm nplai thiab qhov nkag, 10G twb muaj IMO. Thaum 2.5G thiab 5G yuav tsis tau txais kev pom zoo los sis txhawb nqa.
Muaj tsis muaj ntau nti poob muag uas txhawb 2.5G Ethernet thiab 5G Ethernet tsis tau raws li lawv tsuas tau txais kev ua tiav. Tseem, feem ntau cov ntawv teev lus them nyiaj yug lawv tam sim no kuj txhawb 10Gbe.
Dab tsi tshwm sim yog tsim nyog. Ib qho kev kwv yees yog tias muaj 70 billion meter ntawm Cat5e thiab Cat6 cabling tau muag thaum xyoo 2003 thiab 2014. Cov kev lag luam uas muaj cov khoom lag luam nyob hauv seem ntawm qhov sib txawv, nws tsis yog tias cov tuam txhab feem ntau xav ncua cov uas twb muaj kab cab, khoom siv thiab kev lag luam nyob rau hauv tus txheej txheem wireless Ethernet wireless. Yog li no, nws tsis yooj yim rau koj nrhiav tau tias 2.5G Ethernet thiab 5G Ethernet qauv muaj lawv cov zoo.
Cat5 thiab Cat6 cabling tsis tuaj yeem txhawb 10G Ethernet li 100 meters, tab sis lawv yuav tau txais kev txhawb nqa qhov tsim tawm 2.5Gbps thiab 5Gbps, uas yog khaws cov nqi ntawm cov qauv uas twb muaj kab hlau txuas.
Kev hloov tshiab 2.5G thiab 5G yuav ua rau kev xav tau ntawm cov ntaub ntawv nce ntawm cov wireless networking. Tus tshiab 802.11ac Wi-nkaus txheem nce wireless bandwidth, txhawb Ethernet ceev ntawm 1.7 Gbps mus rau 2.5 Gbps. Nrog cov tuaj ntawm lub cim ntxiv ntawm wireless network, 802.11ac Wi-nkaus Wave 2, wireless network speeds yuav nce mus siab li 6.8 Gbps.
Dhau li ntawm qhov kev xav tau los ntawm kev lag luam hauv Wi-nkaus, ib lub 2.5G / 5G version kuj tseem yuav pab tau rau lwm daim ntaub ntawv xws li cov tuam txhab ua lag luam, kev siv cellular Wi-Fi, cov hlwb, cov koob yees duab kev ruaj ntseg, ntau yam siv thiab PoE technology.
Cov kev cai tshiab ob ntawm Ethernet no muaj ntau ntau cov cwj pwm kom paub meej meej, xws li yooj yim siv, rov qab sib tw, ceev dua tsis tau ntxiv kev hloov kho dua tshiab, nce kev nce qib, ntau tus neeg muag khoom, tsis txhob hais txog cov nqi zoo thiab kev ua tau zoo.
Los ntawm cov ntsiab lus saum toj no, peb tuaj yeem txiav txim tau tias cov ntsiab lus 2.5G / 5G Ethernet muaj ob qho zoo thiab kev tsim. Rau cov neeg uas xav hloov upgrade system mus rau 10G, 2.5 G / 5G tsis pab tau. Thaum lub sijhawm ua lag luam me thiab tsev neeg, 2.5G / 5G yog ib txoj hauv kev siv nyiaj tsawg. Tsis muaj teeb meem dab tsi koj lub tshuab cog kab mob, xaiv ib txoj kev cai migration haum yog qhov tseem ceeb tshaj plaws. FOCC muab cov khoom ua kom zoo tshaj plaws rau kab cog, xws li Cat5e cable, Cat6 cable, kev nkag mus rau wireless thiab hloov mus rau PoE.
