I-Cable CPE, iModem yeDatha, iDOCSIS 3.1, i-4xGE, i-SP440
Inkcazo emfutshane:
I-MoreLink's SP440 yiModem yeCable yeDOCSIS 3.1 exhasa i-2×2 OFDM kunye ne-32×8 SC-QAM ukuze inike amava e-intanethi anamandla akhawulezayo.
I-SP440 lukhetho olufanelekileyo kubaqhubi beentambo abafuna ukubonelela ngokufikelela kwi-broadband ekhawulezayo neyoqoqosho kubathengi babo. Inika isantya esifikelela kwi-4Gbps ngokusekwe kwiiports ze-Giga Ethernet ezi-4 nge-interface yayo ye-DOCSIS. I-SP440 ivumela ii-MSO ukuba zinike abathengi bazo usetyenziso oluhlukeneyo lwe-broadband olufana nokunxibelelana ngefowuni, i-HD, kunye nevidiyo ye-UHD xa kuyimfuneko ngokunxibelelana kwe-IP kwi-oce/home oce encinci (SOHO), ukufikelela kwi-intanethi yokuhlala ekhawulezayo, iinkonzo ze-multimedia ezisebenzisanayo, njl.
