I-Cable CPE, Imodemu Yedatha, i-DOCSIS 3.1, i-4xGE, i-SP440
Incazelo emfushane:
I-MoreLink's SP440 iyi-DOCSIS 3.1 Cable Modem esekela i-2×2 OFDM kanye ne-32×8 SC-QAM ukuze inikeze ulwazi olunamandla lwe-inthanethi olusheshayo.
I-SP440 iyisinqumo esifanele sabasebenzisi bekhebula abafuna ukunikeza ukufinyelela kwe-broadband okusheshayo nokungabizi kumakhasimende abo. Inikeza isivinini esifinyelela ku-4Gbps ngokusekelwe kumachweba ama-Giga Ethernet angu-4 nge-interface yayo ye-DOCSIS. I-SP440 ivumela ama-MSO ukuthi anikeze amakhasimende awo izinhlelo zokusebenza ze-broadband ezahlukahlukene njengokuxhumana nge-telecommuting, i-HD, kanye nevidiyo ye-UHD uma kudingeka ngokuxhumeka kwe-IP ku-oce/home oce encane (SOHO), ukufinyelela i-inthanethi yokuhlala okusheshayo, izinsizakalo ze-multimedia ezisebenzisanayo, njll.
