Only six months after introducing its APEX1500 edge QAM, Motorola has delivered a new version with even greater port density.
Steadily rising demand for VOD and streamed content is pushing the industry toward ever-higher QAM density, and toward exploring the potential of a future Cable Converged Access Platform (CCAP). Motorola's APEX3000 universal edge QAM offers eight times the density of its previous universal edge QAM, supporting 384 QAM channels per rack unit (RU), or a total of 1,536 QAM channels per 4RU chassis.
Two APEX3000s can replace two entire racks in the hub of previous-generation edge QAM solutions. Motorola calculates that the new system reduces power per QAM by 72 percent (less than 1 W per QAM at maximum density).
It features 12 10GigE ports – eight primary ports and four backup – empowering operators to ingest enough content to fill every QAM channel with unique narrowcast content.
"We can do full ingest of 1,536 channels in and 1,536 out – non-blocking," said Floyd Wagner, director of global product marketing at Motorola.
Because most operators agree that CCAP migration will take place on a phased deployment model, hybrid networks will be the norm over the next several years, Motorola explained. Operators are faced with balancing investments in legacy technology and future-serving IP-based systems. As a result, Motorola has invested heavily in both the evolving CCAP platform and its legacy CMTS technology.
The company has also upgraded its software for its TX32 decoupled downstream CMTS module. The TXPlus module doubles the downstream capacity of its BSR 64000 CMTS DOCSIS 3.0 cards (64 channels), achieving 384 downstream channels per chassis (it increases EuroDOCSIS 2.0 downstream cards by 50 percent) without having to replace CMTS cards.
Separately, the company will be showcasing its new 4Home Software Platform for Cable. The open-standard and device-agnostic design enables the platform to support a range of disparate devices that will make use of home networks. This is the same platform behind Verizon's Home Control service.
