One of the most common use-cases of Gfast is at the distribution point. In this scenario, the subscribers are often within 150 meters and second-generation Gfast solutions can deliver true gigabit services without the need for expensive and time-consuming last-mile construction costs.
With the typical fiber to the distribution point architecture, fiber is brought to a sealed, outdoor unit of 8,16, or 24 port DPU that is placed close to the home. These devices can be used on a pole, in a pedestal or submerged in the street or sidewalk to serve both single-family dwelling and MDU residents. At close distances, operators can leverage reverse power to deliver services.
One critical component of FTTdp deployments is need for a low-power footprint. The lower the start-up power needed, the further away a reverse-powered DPU can be placed. The Sckipio solution is more power efficient than competitive solutions. As a result, the Sckipio 212Mhz DPUs can be placed an extra 50-80 meters away from the residence than other solutions.
The challenge of higher port densities at this distance is reverse power feeding (RPF). Large port count DPUs (24 and above) require too much power consumption for a single user to power with RPF. Fortunately, using the Sckipio’s cross-DPU vectoring, a 16-port DPU can be reversed powered and cascaded with other boxes to create a 48-port RPF solution. Only Sckipio offers this capability.
Not only does the Sckipio solution support 212Mhz on a single pair, Sckipio can support 212a bonding, which can deliver up to 1.5Gbps of download and 500Mbps of upstream – even at 100 meters.
Sckipio is the only provider of coordinated dynamic time assignment for use in high crosstalk environments such as twisted pair. This means that better upstream performance can be delivered – providing the ability to offer higher aggregate rates for a given PHY rate.
