With four times the port density and 20% lower per-line power consumption than the widely deployed BCM65400 family, the BCM65450 is ideal for the highest-density multi-dwelling unit (MDU) and reverse-powered DPU system designs. Each BCM65450 device supports up to 16 G.fast 212MHz interfaces, with embedded crosstalk cancellation (‘vectoring’) of up to three devices interconnected seamlessly for a fully-vectored 48-port MDU. Coupled with Broadcom’s previously announced BCM65550 vector processor, system designs in excess of 100 lines are now possible with uncompromised crosstalk cancellation across the entire G.fast spectrum.
The BCM65450 does more than increase density and improve efficiency. As a true copper infrastructure platform, it delivers on all of the critical innovations of the copper industry and standards bodies, including: echo-cancellation technology, offering the opportunity to use the full G.fast spectrum for simultaneous upstream and downstream transmission; G.fastback, now standardized in the ITU, a technique that extends gigabit coverage via G.fast backhauling and cascading; a dedicated line-bonding engine to provide previously unachievable multi-gigabit throughput over a set of bonded copper lines; and Dynamic Time Allocation to offer gigabit symmetrical services by dynamically adapting downstream and upstream rates. With all of these, plus fallback to earlier deployments of standardized DSL protocols, the BCM65450 is the ideal copper infrastructure solution for the gigabit broadband era.
