Vectoring Port Density

One of the most critical components to any DPU is the vectoring and the ability for a given DPU to support the density of subscribers sharing a single copper binder. The Sckipio second generation DPUs support the highest density using internal distributed vectoring while supporting the 212a band plan.

Internal Distributed Vectoring

To achieve high port counts while keeping the costs low, Sckipio invented the concept of internal distributed Gfast vectoring. In this approach, each chipset vectoring its ports and coordinates vectoring between chips. This eliminates the need for a separate, external vectoring chipset.

PAY AS YOU GROW

Sckipio’s cross-DPU vectoring changes the business case for Gfast. By starting with a smaller unit and connecting additional units only when the first DPU is full, CAPEX is better aligned with potential revenue. This accelerates breakeven and reduces the CAPEX needed.

LOWER SKU COUNT

With cross-DPU vectoring, operators can use fewer designs and yet meet a much larger set of use-cases. This reduces operating expenses because a single SKU can be put on the truck that supports multiple use-cases. Select the box that covers most of your deployment. And by stacking and bonding you can cover the longer tail of uses cases.

BETTER RPF

Cross-DPU vectoring makes higher port count reverse power feed possible. With cross-DPU vectoring, a single subscriber only needs to support the DPU they are connected to. This reduces the power needed to be injected at the CPE. So, for example, a 48-port vector group can be supported by using three 16-port DPUs that are cross-connected together. The subscriber needs only to maintain power for a single 16-port unit, not a 48-port unit. Only Sckipio offers this flexibility

HIGHER DENSITIES

With cross-DPU vectoring, the telco can connect DPUs together to create larger vector groups – today up to 96 ports while staying within the 212a band plan. Only Sckipio supports more than 24 ports of 212a performance without requiring external vectoring. Today, the Sckipio portfolio offers DPUs from a single port to 96 ports and from 4 ports to 48 ports of bonded 212a performance.

SYMMETRIC-LIKE PERFORMANCE

Only Sckipio provides the ability to support dynamic time assignment (DTA) for both high crosstalk (coordinated DTA) and low crosstalk (independent DTA) environments. Only Sckipio shipped both solutions already in the first generation and the second generation is even more mature and effective.

MULTIPLE OPERATOR VECTORING

While each country has its own regulatory environment, in markets where unbundling is common and/or mandatory, cross-DPU vectoring allows for cross-operator vectoring. In this environment, multiple service providers can share a single copper binder and create one vector group across the various participants. Each service provider will use its own DPU with its own applications and software and the vectoring will be synchronized across the different DPUs. Sckipio makes it possible to achieve both choice and performance using Gfast.
