Ingabe i-transceiver ebonakalayo yocingo kulula ukuyisebenzisa? Yebo kulula ukuyisebenzisa, ngaphandle kwalokho ngeke kube umkhiqizo wokuthuthukiswa komlando wemishini yokuxhumana! I-telephone optical transceiver iyisisetshenziswa esiguqula izimpawu zocingo zendabuko ku...

Izinhlobo zokuxhumana zocingo ezisetshenziswa kakhulu zama-transceiver optical ocingo yilezi: i-loop relay interface (FXO), i-analog subscriber line interface (FXS), i-hotline phone interface (ifoni esemthethweni), isixhumi esibonakalayo socingo sikazibuthe. Ama-transceiver optical ocingo...

Iswishi yenethiwekhi ye-8-port POE "Ungalokothi ushise idivayisi" i-smart POE switch, i-algorithm ethuthukisiwe yokuzizwela inika amandla kuphela okokusebenza kwetheminali ye-IEEE 802.3af, ngakho-ke asikho isidingo sokukhathazeka ngokulimaza imishini yangasese evamile ye-PoE noma engeyona eye-PoE. Isistimu yokuphakelwa kwamandla ehlakaniphile...

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 zingahlinzeka ngezinga lemboni ye-IEEE802...

Abantu abavame ukuthenga amamojula optical bayazi ukuthi amamojula we-fiber optical ngokuvamile adinga ukuqinisekisa ikhodi yokuhambisana, ngoba okwamanje kunezinhlobo ezimbili emakethe, eyodwa iyimojula ehambisanayo esebenza kahle, kanti enye iyimojula ye-optical ye-ori. .

Iswishi ye-PoE ibhekisela ekushintsheni okunganikeza amandla enethiwekhi kumatheminali asebenza kude ngentambo yenethiwekhi. Kuyidivayisi evamile yokuphakelwa kwamandla kumasistimu okunikezwa kwamandla e-PoE. Nokho, uma iswishi ingenawo umsebenzi we-POE, ingeza...

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 ku-swit...

CWDM/DWDM wavelength division multiplexing ukusetshenziswa kwemishini Njengoba izidingo zabantu zomkhawulokudonsa ziya ngokuya ziya phezulu, amadivayisi weDense Wavelength Division Multiplexing (DWDM) enze inqubekelaphambili enkulu ekwehliseni izindleko, futhi ngenxa yalokho aya ngokuya akhula...

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 inebanga elide, eliphezulu...

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 kumasekhondi...
