– First G.fast Single Port DPU with Dynamic Time Assignment
– First G.fast Dynamic Time Assignment over Multiple Vectored Copperwires (Binders)
– First 24 Port G.fast Gear for Asian Telco Standards

Sckipio this week made three major announcements and reminded us of a major announcement it made some months ago about Dynamic Time Allocation DTA, which it originally called Dynamic Bandwidth Assignment (DBA). DTA, which has now been included in the ITU specification for G.fast, allows for automatic, real-time allocation of bandwidth to up and down streams. As demand for one direction decreases, DTA allows the other direction to access more bandwidth. The reason that DTA is important is that the world is at the beginning of two eras that will require that consumers have fast up speeds: live social media streaming as promoted by Twitter, Facebook, YouTube and others plus telemedicine, which needs fast up speeds at the residence for the health care provider to see the patient in high-resolution.
World’s First Single Port G.Fast DPU with Dynamic Time Assignment
The first new Sckipio G.fast technology is intended to connect a single residence to nearby fiber. It works over cablecos’ coax and telcos’ copperwires. It allows service providers to “extend” their fiber GPON networks so that the copper or coax looks like fiber to the provider’s management software. No longer is new and or separate management software needed to manage the coax or copperwire sections.
Sckipio’s reference design for a first-of-its-kind single-port G.fast distribution point unit (DPU) provides up to 1 Gbps of symmetrical broadband over existing coax and copper wiring. To the service provider it’s a virtual fiber GPON network even though it’s over copperwires or coax in MDUs and single-family households (SFUs). A signal port DPU uses one copperwire to connect one residence to the fiber network, which means there is no sharing of bandwidth between neighboring residences. The design uses Sckipio’s dynamic time assignment technology, which provides up to 1Gbps of broadband access in either direction. It also supports reverse power feeding from Microsemi, which makes it easy to install because no electrical outlet is required for the DPU. The home that’s connected supplies the DPU with power that costs the residence about a dollar a year.
The service provider connects the existing coax or copperwire to the DPU, which is connected to fiber, and then ships or installs a G.fast-based modem/router/gateway in the residence. That’s all that’s needed for a 1 Gbps home. And the bonus is that the service provider can use its existing GPON network management software to manage the network all the way to the modem/router/gateway.
Sckipio’s technology uses a very thin management layer for G.fast, which allows service providers to use their existing GPON management software. This speeds up the gigabit rollout by avoiding costly and time-consuming integration of new management protocols by service providers.
Intel and Microsemi partnered with Sckipio on the design, which works within an existing Intel-based GPON management infrastructure. Sckipio said the technology offers equipment makers the fastest path to deployable single-port DPUs.
