Performance analysis: DOCSIS 3.1 cable TV headend combining systems

  • Created: 2016-05-23
  • Size: 7.38 MB
  • Measuring MER performance of QAM signals in passive & active combining systems.



Inner spring design: Delivering network performance through high quality connections

  • Created: 2014-05-13
  • Size: 1.17 MB
  • Well designed inner spring connectors are vitally important to the optimum operation of a network. They help prevent intermittent connections, reduce intermodulation distortion and decrease common path distortion (CPD).

    Discover the three main factors that affect the quality of a connector and how the various combinations of inner spring attributes compare in performance.



MS-828/D Matrix: A smart solution for large-scale CPE testing

  • Created: 2014-05-08
  • Size: 1.49 MB
  • Not only is keeping headend test environments tidy with easy to track cabling a challenge, large scale testing of the latest consumer hardware can require extensive recabling, which is a costly and time consuming exercise.

    This paper introduces a smart solution that eliminates recabling times, simplifies the tracking of test combinations and is scalable to meet individual needs. Its passive design is suitable for forward and return path applications.



The future of narrowcast insertion: Next generation, CCAP compliant RF combining

  • Created: 2013-05-02
  • Size: 3.38 MB
  • This white paper looks at the advantages of using the converged cable access platform (CCAP) standard to implement converged video and data services.

    It also explores ways of overcoming some of the challenges for headend combining systems which need to be considered in your CCAP migration roadmap.



Upstream quality improvement: Carrier to noise improvement in the upstream

  • Created: 2012-08-09
  • Size: 3 MB
  • Demand for higher data throughput in the return path is growing significantly and techniques such as using 64 QAM channels in the upstream need to be deployed to keep up with the competition. This requires a higher carrier to noise ratio in the upstream path of the networks, which can be challenging to achieve.

    This paper examines factors that can have a negative impact on upstream quality and offers practical solutions for improvement gained from our experience of working to enhance European broadband networks.



DOCSIS 3: Are your lasers ready?

  • Created: 2011-12-06
  • Size: 1.23 MB
  • This white paper looks at the DOCSIS 3 standard, and the reasons why out-of-date laser transmitters need to be upgraded to make the most of this standard.
