DOCSIS® 3.1 – An Overview. Adapted from an SCTE webcast by Cisco’s Ron Hranac and Broadcom’s Bruce Currivan. Data-Over-Cable Service Interface Specifications. DOCSIS 1.0 gave us standards-based interoperability, which means “certified” cable modems from multiple vendors work with “qualified”
Officially released by CableLabs in 2013, the DOCSIS 3.1 specifications are the current industry standard for providing high-quality internet access over hybrid fiber coax (HFC) networks.
This DOCSIS® specification is the result of a cooperative effort undertaken at the direction of Cable Television Laboratories, Inc. for the benefit of the cable industry and its customers.
CG3000 DOCSIS 3.1 RGW operates simultaneously both DOCSIS 3.1 and DOCSIS 3.0 32x8. It makes extreme speed up to 10 Gigabit per second, and enables operators to provide premium services while data traffic for HD/UHD video streaming and complex internet usage at home are increasing.
The ECM31 and the DRM31 series Rugged Cable Modem is DOCSIS® 3.1 and EuroDOCSISTM 3.1 compliant and is specially designed for installations where temperatures can be extreme, uncontrolled, and typical of the outside plant in an HFC cable network.
The TC4400 cable modem is fully compliant with the latest DOCSIS 3.1 specification as published by CableLabs® and is capable of delivering downstream cable speeds of up to 3.6 Gbps by using 2 Orthogonal Frequency-Division Multiplexing (OFDM) downstream channels (and up to 5 Gbps in case of.
Frequency Range: 5MHz ~ 42MHz/85MHz switchable. Modulation: QPSK or 8/16/32/64/128 QAM and OFDMA: to 4096 QAM. Maximum DOCSIS 3.1 Data Rate: 2 x 96MHz OFDMA channels provide capacity up to 2Gbps. Maximum DOCSIS 3.0 Data Rate: 8 upstream channels provide speeds up to 246Mbps.
