Based on the estimated plant loss and known CMTS input power, one can conclude that the DOCSIS 3.1 cable modem should be transmitting SC-QAM channels around 44.6 dBmV and the OFDMA channel around 35.4 dBmV.
11 sty 2024 · The DOCSIS 3.1 modem has a 32X8 channel bonding, so you can expect faster download speeds and decent upload speeds. Plus, the modem supports speeds up to 6 Gbps, which means it would work well with high-speed gigabit plans.
DOCSIS 3.1 downstream orthogonal frequency division multiplexing (OFDM) signals support a variety of modulation orders up to 4096-QAM (optionally as high as 8192-QAM and 16384-QAM) over channel bandwidths ranging from a minimum of 24 MHz to a maximum of 192 MHz.
This paper looks at the two main technologies behind this latest version: orthogonal frequency domain multiplexing (OFDM) and low density parity check (LDPC). It also covers the best testing practices to get DOCSIS 3.1 running at peak performance levels.
Cable modems communicate directly with Internet service providers (ISP) to transmit data back and forth. This is also known as downstream and upstream channels of data and requires multiple channels for each to offer optimal performance. Here’s everything know about how cable modem channels work.
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”
8 maj 2023 · If you want cable internet in the gigabit or multi-gigabit range, you need a DOCSIS 3.1 modem, as cable providers require the improvements in the DOCSIS 3.1 standard to deliver that bandwidth under real-world conditions.
