As we are stepping on board the journey into the future, and adding devices to our growing range of digital appliances, there is a major issue holding us back: Current broadband networks are simply not geared to manage the amount of multi gigabit speeds required to effectively run and operate all the machines in our homes. But DOCSIS 3.1 can change that.

DOCSIS 3.1 provides new possibilities

DOCSIS 3.1, the new standard for coaxial distribution. Looking to the markets, the demand for more robust bandwidth is a global macro trend that is fueled by the increasing demand for streaming and IP video services. For the operators, getting this right will be crucial to gaining a competitive edge and lowering churn via satisfied customers.

However, this is also important on a much larger scale and will become central to nations’ standard- and quality of living, and competitive performance as societies and the countries failing to put sufficient focus on digital inclusion will surely fall behind.

New standards in the coaxial area, the DOCSIS 3.1, technology, provide possibilities for even faster broadband on existing coaxial cables, in practice 1Gb to every home.

With the introduction of DOCSIS 3.1 it is possible to accelerate faster broadband performance on existing coaxial cables and thereby improving connectivity between people and societies via innovative thinking rooted in stable high-speed broadband performance.

Optimizing performance with DOCSIS 3.1 Products

When upgrading to DOCSIS 3.1 you need to exchange the passive electronic infrastructure to handle higher frequencies, aligning the network to handle a narrower window in the return path and reduce noise due to an increased modulation index. With a DKT solution, you will have a complete product portfolio for the passive distribution network with optimized performance ready for DOCSIS 3.1.



All CATV network operators regularly encounter faults in their network. These faults are caused by defect interconnections between cables and network components. The DKT Signia product series has brass connectors, which do not cold-flow. Also, the connectors are plated with a nickel-tin alloy, this being very resistant to corrosion. High quality cable connectors are also made in brass with nickel-tin plating. As a result, using the Signia products considerably improves the operation of the CATV network.

Signia splitter for DOCSIS 3.1


From an electric aspect the Signia product series has a low failure rate. All splitters and taps in the network contain ferrite cores. At high power these cores are driven above their linear range of operation; hence signals are intermixed (passive intermodulation). This is observed as increased noise in the network, which may result in periodic failures that can be extremely difficult to locate and correct.

In the Signia product series the ferrite cores have a much higher linear range of operation. All ferrite cores have a memory effect; when the cores are exposed to a strong signal their linear range of operation is permanently narrowed. The ferrite cores used in the Signia product series are more resistant to this effect. Additionally, there is built-in protection in the Signia product series. This protects the ferrite cores against unwanted strong signals.

Push-in-outlet (PIO)


This “PIO”concept is a solution for changing frequencies on up- and downstream and will prepare the Home for future DOCSIS 3.1 upgrades. This means that roll-out can now be performed swiftly and at a higher speed. This will increase reaction time and customer satisfaction!

Push in outlet (PIO)


When upgrading/preparing the home for DOCSIS 3.1, we strongly recommend that the service is terminated at the first point of entry, the outlet. This simplification of the in-home coaxial network has the benefit of ensuring proper SNR as required for true DOCSIS 3.1 operation. It eases troubleshooting as the demarcation point/first outlet at the customer premises becomes the “services delivery point”. The In-home network is thereby separated from the distribution network and noise is thus eliminated.

DOCSIS 3.1 service termination in the home

  • Terminate DOCSIS 3.1 at the first point of entry, in the push in outlet.
  • Excludes distribution of DOCSIS 3.1 in the home => Simpler installation.
  • Eliminates return path noise contribution from the home (ingress and in-home components) => more robust network.
  • Upgrade only the first outlet in the home the remainder of the infrastructure can be reused = lower CAPEX.
  • Visit the customer once, subsequent upgrades are very simple/fast and can even be a Do-It-Yourself (DIY) approach = lower OPEX.
  • Supports smooth migration of the return path, 65 => 85 => 204 MHz => Symmetric.


Business Case Impact

  • Faster frequency upgrade in the home without installer presence => 80 to 90% truck roll savings.
  • Faster reaction time by service upgrade, allowing mass marketing => improved ARPU & ROI.
  • Faster roll-out due to D.3.1. service termination at the entrance of the home (remainder of home remains untouched) equals 65-75% reduced installer time in the home.


Band-Stop-Filters to handle TV packages to end-users. Steep slopes, efficient stop band attenuation and low insertion loss.

Equalizers & Attenuators

Efficient inline equalizers as required to align the signal level of the return path to reach the correct SNR and a range of inline attenuators to align network signal levels.


Significantly improved screening efficiency to eliminate noise and a design that can handle changes in frequencies (see “PIO”).

Home-network interface

Terminating the D3.1 stream at the doorstep; eliminating return path noise generated in the home network, either via a DVU or a PIO outlets.

Splitters & taps

The NiTin brass connectors eliminate the primary cause of network faults; loosening of connectors due to “cold-flow”. This significantly reduces the noise.

Power splitters

A robust and well-proven construction that has been refined over the years and now in a D3.1 version.
