CPE ya Chingwe, Modemu ya Deta, DOCSIS 3.1, 4xGE, SP440

Kufotokozera Kwachidule:

SP440 ya MoreLink ndi DOCSIS 3.1 Cable Modem yomwe imathandizira 2×2 OFDM ndi 32×8 SC-QAM kuti ipereke intaneti yamphamvu kwambiri.

SP440 ndi chisankho chabwino kwambiri kwa ogwiritsa ntchito mawaya omwe akufuna kupereka mwayi wolumikizirana mwachangu komanso mopanda ndalama kwa makasitomala awo. Imapereka liwiro lofika pa 4Gbps kutengera madoko anayi a Giga Ethernet kudzera pa mawonekedwe ake a DOCSIS. SP440 imalola ma MSO kupatsa makasitomala awo mapulogalamu osiyanasiyana a broadband monga telecommuting, HD, ndi UHD video pakafunika kudzera pa IP yolumikizira ku oce/home oce yaying'ono (SOHO), intaneti yothamanga kwambiri yapakhomo, mautumiki olumikizirana a multimedia, ndi zina zotero.

SP440 ya MoreLink ndi DOCSIS 3.1 Cable Modem yomwe imathandizira 2x2 OFDM ndi 32x8 SC-QAM kuti ipereke intaneti yamphamvu kwambiri.

SP440 ndi chipangizo chanzeru chomwe chimawonjezera zinthu zake zoyambira zotumizira deta ndi chithandizo cha IPv6, zomwe zimapangitsa kuti chikhale choyenera kwambiri potumiza deta kutengera protocol iyi.
