CPE ya Cable, Modemu y'amakuru, DOCSIS 3.1, 4xGE, SP440
Ibisobanuro bigufi:
SP440 ya MoreLink ni Modem ya DOCSIS 3.1 Cable ifasha 2 × 2 OFDM na 32 × 8 SC-QAM kugira ngo itange ubunararibonye bukomeye bwa interineti yihuta cyane.
SP440 ni amahitamo meza ku bakoresha insinga bashaka gutanga interineti yihuta kandi ihendutse ku bakiriya babo. Itanga umuvuduko ugera kuri 4Gbps hashingiwe ku byambu bine bya Giga Ethernet hakoreshejwe DOCSIS interface yayo. SP440 yemerera MSOs guha abakiriya babo porogaramu zitandukanye za interineti nko gukoresha itumanaho, HD, na videwo ya UHD igihe cyose bikenewe hakoreshejwe IP kuri oce/home oce nto (SOHO), interineti yihuta yo mu rugo, serivisi z'itumanaho zihuza, n'ibindi.
