PoE hloov pauv yog qhov hloov pauv uas txhawb nqa lub zog rau lub network cable. Piv nrog rau cov keyboards zoo tib yam, lub hwj chim txais lub davhlau ya nyob twg (xws li AP, lub koob yees duab digital, thiab lwm yam) tsis tas yuav tsum tau xaim rau lub hwj chim mov, uas muaj kev ntseeg siab dua rau tag nrho lub network ...

Kev nkag siab txog kev ua tau zoo ntawm optical fiber thiab tooj liab hlau tuaj yeem ua qhov kev xaiv zoo dua. Yog li dab tsi cov yam ntxwv ua optical fiber ntau thiab tooj liab hlau muaj? 1. Copper hlau yam ntxwv Ntxiv rau qhov saum toj no-hais zoo tiv thaiv kev cuam tshuam, tsis pub lwm tus paub, ib ...

Kev xaiv ntawm cov ntaub ntawv chaw xa xov xwm yog ib txwm muaj kev tsis sib haum xeeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw tshwj xeeb (xws li cov chaw zov me nyuam). Cov teeb meem kev lag luam thiab kev lag luam yuav tsum tau txiav txim siab. Qee tus neeg xav tias yuav tsum xaiv cov xov tooj tooj liab, thaum lwm tus thi...

Thaum muas ib qho kev hloov pauv, cov neeg siv khoom yuav raug nug seb lawv puas xav tau ib hom fiber ntau, ib hom dual-fiber, ntau hom dual-fiber, thiab lwm yam, thiab lawv siv qhov twg. Cov no tsuas yog nkag siab thaum lawv muaj kev nkag siab meej txog cov pu...

PoE injector ua haujlwm li cas? Thaum cov keyboards lossis lwm yam khoom siv uas tsis muaj lub zog ua haujlwm txuas nrog cov khoom siv hluav taws xob (xws li IP koob yees duab, wireless APs, thiab lwm yam), PoE fais fab mov tuaj yeem muab lub zog thiab cov ntaub ntawv xa mus rau cov khoom siv fais fab no ...

PoE (Power dua Ethernet) yog hais txog lub hwj chim tshaj Ethernet thev naus laus zis uas ib txhij xa hluav taws xob thiab cov ntaub ntawv los ntawm cov kab sib tw twisted. Daim ntawv thov ntawm cov thev naus laus zis no tuaj yeem txhim kho kev ruaj ntseg thiab hloov pauv ntawm lub network, yog li nws yog ...

Kev sib kis tus nqi yog qhov tseem ceeb hauv kev txiav txim siab hom Ethernet hloov chaw nres nkoj. Tam sim no, tus nqi sib kis ntawm Ethernet keyboards yog 1G / 10G / 25G / 40G / 100G lossis ntau dua. Cov hauv qab no yog cov chaw nres nkoj loj ntawm cov Ethernet keyboards nrog dif ...

Yuav ua li cas ntsuas lub network qeeb hauv Ethernet hloov? Raws li tuaj yeem pom los ntawm tshooj dhau los, hloov ncua ncua yog ib qho tseem ceeb uas ua rau lub network qeeb. Yog li cas peb ntsuas hloov latency? Hloov ncua yog ntsuas los ntawm qhov chaw nres nkoj mus rau qhov chaw nres nkoj ntawm Ethernet s ...

Network latency yog hais txog lub sijhawm tos lub network, uas yog hais txog lub sijhawm ncig mus ncig rau cov ntaub ntawv xa tawm los ntawm tus neeg siv lub computer mus rau lub vev xaib server, thiab tom qab ntawd tam sim ntawd los ntawm lub vev xaib server mus rau tus neeg siv lub computer. Network ncua sij hawm yog ib qho ntawm t...

Lub hwj chim dhau Ethernet (PoE) yog lub tshuab hluav taws xob siv hluav taws xob raws li thaj chaw hauv cheeb tsam network (LAN), uas tuaj yeem xa hluav taws xob thiab cov ntaub ntawv mus rau lub cuab yeej los ntawm lub network cable hauv Ethernet. Kev siv cov thev naus laus zis no tuaj yeem txo cov nqi khiav lag luam thiab txuag ...
