C100G & C40G CCAP
Casa Systems’ track record of firsts – such as its distributed access architecture – has been recognised by BTR’s Diamond Technology Review on 10 September 2016.
This CCAP (Converged Cable Access Platform) architecture helps cable operators push capacity to the edge as they transition from a centralised cable access architecture to a distributed network.
The elegance of the design means that its ready to deliver gigabit+ services with a true CCAP platform: it enables smooth transition from DOCSIS 3.0 to DOCSIS 3.1 and to distributed access architecture. It means you can offer gigabit services now – against your competitors – to win market share.
The effect of this decentralised access architecture is to reduce rack space and power requirements by up to 30% over legacy systems. The design also increases Upstream capacity to deliver better customer experiences.
Casa offers a range of distributed access node form factors that perform DOCSIS and EQAM PHY functions. Either 10G Ethernet or 10G PON transport can be used between the CCAP core and the DA nodes.
The plug-and-play design makes for easy deployment while retaining MAC functions in the headend reduces the complexity of the software in the distributed access nodes and means fewer truck rolls. These nodes are presented as extensions of the CCAP core and are collectively managed as a single, large CCAP.
The CCAP Services Card (CSC) has 8x10G Ethernet/EPON interfaces. The C100G is 13 RU and can house 12 CSCs for a maximum of 96 ports, which means 96-384 distributed access nodes per C100G. The smaller full CCAP solution, the 6 RU C40G, houses 4 CSCs, for a maximum of 32 ports, meaning 32-128 distributed access nodes.
The design of the platforms support the DOCSIS Provisioning of EPON (DPoE) specifications.
Three distributed access nodes models have been designed for single-dwelling homes, and multi-dwelling unit applications.
All elements of the C100G are redundant, either N+1 or 1+1, and all are hot-swappable which adds up to 99.999% system availability. In addition, the integrated architecture of the C100G CCAP minimises the effort and time required for initial installation, configuration, and troubleshooting. Cable operators deploying dense (multi-channel) DOCSIS downstream service groups will realise significant savings in terms of head-end real estate (rack space), powering, and cooling requirements by deploying the Casa Systems CCAP.
If you are planning DOCSIS 3.1 services, then the C100G and the C40G are capable to get you there simply when you are ready to implement.
