Isingeniso somkhiqizo we-8-port poe switch
Iswishi ye-POE enezimbobo eziyisishiyagalombili (JHA-P30208CBMH) ihlinzeka ngamandla nokudluliswa kwedatha kusetshenziswa izintambo ze-Category 5 Ethernet ezivela endaweni yenethiwekhi.8+2 izimbobo ze-Ethernet ezisheshayo zingasetshenziselwa uxhumano lwe-10/100Mps, lapho izimbobo ezingu-8 zinganikeza amandla embonini e-IEEE802.3af.Ukuzizwa okuthuthukile kwe-al...Funda kabanzi -
Ungahlola kanjani ukuhambisana kwamamojula optical ahambisanayo?
Abantu abavame ukuthenga amamojula optical bayazi ukuthi amamojula we-optical fiber ngokuvamile adinga ukuqinisekisa ikhodi yokuhambisana, ngoba okwamanje kunezinhlobo ezimbili emakethe, eyodwa iyimojula ehambisanayo esebenza kahle, kanti enye iyimojula ye-optical ye-original switch brand. .Ukubheja kwegebe lentengo...Funda kabanzi -
Ungakuthola kanjani ukunikezwa kwamandla kwe-POE kokushintshwa okujwayelekile?
Iswishi ye-PoE ibhekisela ekushintsheni okunganikeza amandla enethiwekhi kumatheminali asebenza kude ngentambo yenethiwekhi.Kuyidivayisi evamile yokuphakelwa kwamandla kumasistimu okunikezwa kwamandla e-PoE.Kodwa-ke, uma iswishi ingenawo umsebenzi we-POE, ingabe imojula eyengeziwe yokuphakelwa kwamandla ka-poe ingangezwa...Funda kabanzi -
Isingeniso sokusebenzisa amamojula optical
Imojuli ye-Optical, ikakhulukazi ibhekisela kumojula encane ehlanganisiwe yokubona engashintshwa ngokushisa.Kuyimojuli ye-optical engashintshwa ngokushisa ngesikhathi sokusebenza futhi isetshenziswe embobeni yedivayisi.Isetshenziswa kakhulu ukuxhuma idivayisi (ngokuvamile ibhekisela ekushintsheni noma kudivayisi yomzila).Ugesi...Funda kabanzi -
Yikuphi okungcono ukusebenzisa i-CWDM/DWDM Multiplexer?
CWDM/DWDM wavelength division multiplexing ukusetshenziswa kwemishini Njengoba izidingo zabantu zomkhawulokudonsa ziya ngokuya zikhuphuka, amadivayisi weDense Wavelength Division Multiplexing (DWDM) enze inqubekelaphambili enkulu ekwehliseni izindleko, futhi ngenxa yalokho athandwa kakhulu emakethe.Nokho,...Funda kabanzi -
Uyini umehluko phakathi kwe-CWDM/DWDM Multiplexer?
Ekwakhiweni kwamanethiwekhi endawo yedolobha elikhulu (ikakhulukazi amanethiwekhi okudlulisa amehlo e-OTN amabanga amade), imishini yokuphindaphinda ye-wavelength division ibaluleke kakhulu.Imishini ye-DWDM dense wavelength division multiplexing inamakhono okudlulisela ibanga elide, anomkhawulokudonsa ophezulu;...Funda kabanzi -
Yini ebangela ukuthi isiginali yokuguqula i-RS485 iphazamiseke?
Umsebenzi oyinhloko wesiguquli se-485 ukuguqula isignali ye-RS-232 enesiphetho esisodwa ibe isignali elinganiselwe ye-RS-485 noma i-RS-422.Ngenxa yokudluliswa kolwazi olude kanye nekhono eliqinile lokulwa nokuphazamiseka, iziguquli ze-rs485 zisetshenziswa kabanzi kwezokuxhumana ngokuvikeleka nakweminye imikhakha....Funda kabanzi -
Yiziphi izizathu zokwehluleka kwemojula ye-optical?
Imojula ye-optical isetshenziswa kakhulu ukuguqula isignali kagesi kudivayisi (imvamisa ibhekisa ku-switch noma idivayisi ye-router) ibe isignali ye-optical, bese idlulisela nge-fiber optical (esetshenziswa ukuphela kokudlulisa kwe-optical module), futhi ingathola i-optica yangaphandle...Funda kabanzi -
Uyini umehluko phakathi kwechweba le-RJ45 kanye nembobo ye-SFP yokushintsha?
Njengoba sonke sazi, ukushintshwa kwe-Gigabit Ethernet ngokuvamile kunezinhlobo ezimbili zamachweba: amachweba we-RJ45 namachweba we-SFP.Zombili izinhlobo zamachweba zingathwala ukudluliselwa kwe-Gigabit Ethernet, ngakho-ke yini umehluko phakathi kwazo?Hlobo luni lwe-port ye-Gigabit Ethernet switch okufanele isetshenziselwe ukubona isixhumi se-Gigabit Ethernet...Funda kabanzi -
