Xadhkaha shabakadda ee Cat5e: Sidee loo isticmaalaa sahayda korantada ee PoE?Intee in le'eg ayay tahay gudbinta calaamaduhu?

Nidaamka kamaradaha IP iyo nidaamka fiilooyinka shabakadda 100Mbps, waxaan inta badan u isticmaalnaa fiilada shabakadda Cat5e ee gudbinta calaamadaha iyo korontada.Elzoneta ayaa kuu sharxi doonta aqoonta aasaasiga ah sida hoos:

Sida loo isticmaalo sahayda korantada ee PoE?

Korontada, waa inaan haysanaa fikradda PoE marka hore.PoE (Power over Ethernet), macnaheedu waa in korontadu ay ka soo baxayso beddelka PoE una gudubta marinnada IP-ku-salaysan (sida talefanka IP, barta marinka wlan iyo kamaradaha IP) iyada oo loo marayo fiilada shabakadda ee Cat5e.Dabcan, labada beddelka iyo terminaalka IP-ku-salaysan labaduba waxay leeyihiin module PoE-ga ah;Haddii terminaalka IP-ku-salaysan aanu lahayn module PoE, waxay u baahan tahay inay isticmaasho Standard PoE splitter.

Caadi ahaan, waxaanu dooranaa inaanu isticmaalno beddelka caalamiga ah ee PoE, kaas oo taageera 48V-52V, raacaya IEEE802.3af/802.3at.Sababtoo ah dareemahan PoE wuxuu leeyahay shaqada ogaanshaha ee PoE.Haddii aan isticmaalno beddelka PoE-ga ee aan caadiga ahayn, 12V ama 24V, iyada oo aan lahayn shaqada PoE smart detection, marka ay soo saarto awoodda korantada ee terminaalka IP-ku-salaysan si toos ah iyada oo aan loo eegin in ay leeyihiin module PoE-ga ama haddii kale, way fududahay in la gubo dekedaha IP-ku-salaysan. , xitaa waxay dhaawacdaa moduleka awoodda.

Intee in le'eg ayay tahay gudbinta calaamaduhu?

Fogaanta gudbinta fiilada shabakadu waxay kuxirantahay agabka fiilada.Caadi ahaan, waxay u baahan tahay in la isticmaalo naxaasta aan oksijiinta lahayn, sababtoo ah iska caabbinta naxaasta aan oksijiinta lahayn ayaa ka yar, gudaha 30 ohms ee 300 mitir, sidoo kale cabbirka xudunta naxaasta guud ahaan waa 0.45-0.51mm.Eray ahaan, inta weyn ee cabbirka xudunta naxaasta, iska caabbinta yar, ayaa sii dheereysa fogaanta gudbinta.

Marka loo eego halbeegga Ethernet, masaafada ugu badan ee gudbinta calaamadda ee beddelka PoE waa 100 mitir, taas oo macnaheedu yahay beddelka POE wuxuu adeegsadaa fiilooyinka shabakadda caalamiga ah ee sahayda korontadu waxay ku xaddidan tahay 100 mitir sidoo kale.In ka badan 100 mitir, xogta waa la daahi karaa oo waayi kartaa.Si loo hubiyo tayada mashruuca, waxaan guud ahaan qaadnaa 80-90 mitir ee fiilooyinka.

Qaar ka mid ah furayaasha POE ee waxqabadka sare leh ayaa sheeganaya inay awood u leeyihiin inay gudbiyaan calaamadaha illaa 250 mitir ee shabakadda 100Mbps, ma runbaa?

Haa, laakiin gudbinta signalka ayaa laga dhimay 100Mbps ilaa 10Mbps (bandwidth), ka dibna fogaanta gudbinta signalka ayaa la kordhin karaa ilaa Max 250 (cable with oxygen-free copper core).Farsamadani ma bixin karto xawaaraha sare;Taa lidkeeda, xadhkaha xadhkaha goostay ayaa laga soo ururiyay 100Mbps ilaa 10Mbps, oo aan u fiicnayn gudbinta qeexitaanka sare ee sawirada la socodka.10Mbps macnaheedu waa 2 ama 3 xabbo oo kamaradaha 4MP IP ah oo keliya ayaa la geli karaa fiiladan Cat5e, mid kasta oo 4MP kamarad IP ah baaxaddeedu waa Max 2-3Mbps ee goobta firfircoon.Eray ahaan, fiilada shabakadda Cat5e kama badna 100 mitir ee fiilooyinka.

Fiilada shabakadda ELZONETA Cat5e waxay isticmaashaa xudunta sare ee oksijiin-free oo leh dhexroorka xudunta u ah 0.47mm, si uu u dhigmo kamarada PoE IP iyo beddelka tayada sare ee PoE.Tani waxay xaqiijinaysaa gudbinta calaamadaha iyo xasiloonida sahayda korantada ee dhammaan nidaamka ilaalinta CCTV.
