Distributed CCAP Solutions
Evolution of Cable Networks
The demand for bandwidth is sharpening competition in the broadband market. Common coax feeds have evolved into high-performance hybrid fiber coax (HFC) networks that handle not only TV signals, but data traffic, telephony and video-on-demand content.
Rising bandwidth demand and the number of network users has been driving the headend CCAP to capacity limits. Future bandwidth expansion requirements cannot be met with conventional network structures. Solving this capacity problem has often separated individual components of the CCAP and placed them closer to the end customer.
Distributed Access Architecture (DAA) Networks
The Remote MAC-PHY technology with Distributed CCAP nodes is a further development of the Remote PHY approach. In the Remote PHY concept, the Media Access Control (MAC) layer remains in the headend, while only the PHY layer is moved into the node. The physical separation of the two layers comes with emerging synchronization and communication challenges particular if the MAC and PHY layers are integrated in platforms from different manufacturers and are located many miles apart.
Superfluous Headend CMTS
Within Distributed CCAP architectures, PHY and MAC layer are moved into the node. Thus, only the monitoring and control, as well as the technology for optical digital transmission, remain in the headend. A headend CMTS becomes superfluous because it is integrated within the Distributed CCAP Node. This meets the challenges of timing and synchronization between node and headend devices. By using this technology, signal quality and transmission speeds increase. In addition, big savings in costs, space and energy consumption in the headend can be achieved.
Easy Integration in Current Networks
Distributed CCAP Nodes are not only suitable for new network infrastructures; they can also be integrated into existing networks to scale the existing infrastructure. With the Remote MAC-PHY topology, Distributed CCAP nodes can be used without changing the existing infrastructure simply by replacing the existing HFC optical nodes. Remote MAC-PHY nodes support all common DOCSIS standards and also work in conjunction with Remote PHY devices or conventional CMTS systems.
