Isingeniso I-JHA-P41208BMHseries switches ihlinzeka ngenodi eyodwa yenethiwekhi isebenzisa ikhebula le-Cat5 ukudluliswa kanyekanye kwedatha namandla, lapho amandla e-AC engenamandla noma ephazamisa amandla (njengamakhamera we-PTZ namadivayisi we-WiMAX), uchungechunge lwe-JHA-P41208BMH lwenzelwe amanethiwekhi angenantambo, izinhlelo zokusebenza ezizenzakalelayo zokuphepha. Ukushintshwa kwe-JHA-P41208BMHseries kunciphisa ngokuphawulekayo izindleko zokufaka izintambo kumsebenzisi wamandla, izindawo zokufinyelela ze-LAN engenantambo, amakhamera okuqapha ividiyo nezinye izinto zokusebenza kufanele zisetshenziswe ukuze kusekelwe kangcono izinsizakalo ezintsha nezinhlelo zokusebenza, kunikeze abasebenzisi ukuguquguquka okuphezulu nokuhamba. I-algorithm yokuzizwela ethuthukisiwe kuphela yokunikezwa kwamandla kwemishini yesiphetho se-PD ejwayelekile, ngakho-ke asikho isidingo sokukhathazeka ngokulimala kwempahla ye-PoE eyimfihlo noma engajwayelekile. Idizayini elula nethembekile, i-JHA-P41208BMHuchungechunge lwezidingo zokuhlonza ezizenzakalelayo ze-PoE, isivinini, i-duplex, nokusebenzisa i-Auto Up link TM uhlobo lwekhebula.

Umklamo uhambisana ne-40GBASE-SR4 kanye ne-40GBASE-IR4 yezinga le-IEEE P802.3ba. I-module iguqula iziteshi ze-4 zokufakwayo (ch) zedatha kagesi ye-10Gb / s kumasignali we-4 CWDM optical, futhi iphindaphinda ibe isiteshi esisodwa se-40Gb / s yokudlulisa optical. Ngokuhlehlayo, ohlangothini lomamukeli, imojula i-optically de-multiplexes okokufaka kwe-40Gb/s kumasignali amashaneli angu-4 CWDM, futhi iwaguqulela kudatha kagesi ephumayo yesiteshi esingu-4. Amaza amaphakathi eziteshi ezi-4 ze-CWDM angu-1271, 1291, 1311 kanye no-1331 nm njengamalungu egridi ye-wavelength ye-CWDM echazwe ku-ITU-T G694.2. Iqukethe isixhumi se-LC esiyi-duplex yesixhumi esibonakalayo esibonakalayo nesixhumi samaphini angama-38 esixhumi esibonakalayo sikagesi. Ukuze unciphise ukuhlakazeka kokubona ohlelweni olude, i-multimode fiber (MMF) kufanele isetshenziswe kule mojula. Umkhiqizo uklanywe nge-form factor, uxhumano lwe-optical/electric kanye ne-digital diagnostic interface ngokuvumelana ne-QSFP Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazanyiswa kwe-EMI. Imojula isebenza kugesi owodwa we-+3.3V kanye namasiginali okulawula umhlaba wonke we-LVCMOS/LVTTL njengeModule Present, Setha Kabusha, Ukuphazamisa kanye Nemodi Yamandla Aphansi ayatholakala namamojula. I-serial interface enezintambo ezi-2 iyatholakala ukuze ithumele futhi yamukele amasiginali okulawula ayinkimbinkimbi kanye nokuthola ulwazi lokuxilonga lwedijithali. Iziteshi ngazinye zingasingathwa futhi iziteshi ezingasetshenzisiwe zingavalwa ukuze umklamo ube nezimo eziguquguqukayo. I-TQP10 iklanywe nge-form factor, uxhumano lwe-optical/electrical kanye ne-digital diagnostic interface ngokuvumelana ne-QSFP Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazanyiswa kwe-EMI. Imojula inikeza ukusebenza okuphezulu kakhulu nokuhlanganiswa kwesici, okufinyeleleka nge-serial interface enezintambo ezimbili. • Absolute Maximum Izilinganiso Ipharamitha Symbol Min.
