Ikhebula CPE, Imodemu Yedatha, DOCSIS 3.1, 4xGE, SP440
Incazelo emfushane:
I-SP440 ye-MoreLink iyimodemu yekhebula ye-DOCSIS 3.1 esekela i-2×2 OFDM kanye ne-32×8 SC-QAM ukuze ilethe okuhlangenwe nakho kwe-inthanethi kwesivinini esiphezulu.
I-SP440 iyinketho efanelekile yabaqhubi bezintambo abafuna ukunikeza ukufinyelela kwe-broadband yezomnotho ngesivinini esiphezulu kusisekelo samakhasimende abo.Iletha isivinini esifika ku-4Gbps ngokusekelwe kumachweba angu-4 we-Giga Ethernet ngaphezu kwesixhumi esibonakalayo se-DOCSIS.I-SP440 ivumela ama-MSO ukuthi anikeze amakhasimende awo izinhlelo zokusebenza ezihlukahlukene ze-broadband ezifana ne-telecommuting, HD, kanye nevidiyo ye-UHD efunwayo phezu koxhumano lwe-IP ku-oce/home oce encane (SOHO), ukufinyelela ku-inthanethi okuhlala ngesivinini esiphezulu, izinsiza ze-multimedia ezisebenzisanayo, njll.
