CableLabs Completes First Testing of DOCSIS 4.0 Equipment Interoperability

Cable modems successfully linked to cable modem termination system equipment in a test of DOCSIS 4.0 technology interoperability, CableLabs Principal Architect Doug Jones blogged this week. The event, at CableLabs last month, "passed high-speed traffic. Very high speed, as in gigabits-per-second downstream and upstream," he said. Another interoperability session is scheduled for later this month as the cable industry and suppliers "keep pushing a more rigorous and deeper understanding of the DOCSIS 4.0 specifications and product maturity," he said.
