Chingwe CPE, Data Modem, DOCSIS 3.1, 4xGE, SP440
Kufotokozera Kwachidule:
MoreLink's SP440 ndi DOCSIS 3.1 Cable Modem yothandizira 2 × 2 OFDM ndi 32×8 SC-QAM kuti ipereke chidziwitso champhamvu chapaintaneti.
SP440 ndiye chisankho chabwino kwambiri kwa ogwiritsa ntchito chingwe omwe akufuna kupereka mwayi wothamanga kwambiri komanso wachuma kwa makasitomala awo.Imapereka liwiro mpaka 4Gbps kutengera madoko 4 a Giga Ethernet pamawonekedwe ake a DOCSIS.SP440 imalola MSOs kupatsa makasitomala awo mapulogalamu osiyanasiyana a Broadband monga telecommuting, HD, ndi kanema wa UHD pakufunika pa kulumikizidwa kwa IP ku kanyumba kakang'ono ka oce/home oce (SOHO), intaneti yothamanga kwambiri, mautumiki ochezera a pa TV, ndi zina zambiri.
