    product overview

    The Model CFA-24A Transparent Cable Farm Automation Switch is a transparent, electrically neutral, switching device that allows up to twenty-four incoming cable farm lines to be switched to five different loop segments. Use your own cable or purchase cable from Telebyte (see Ordering Information).

    Operating in a frequency band up to 212 MHz, the CFA-24A is highly suited to lab-grade testing of next-gen devices where live crosstalk is required (e.g., VDSL2 Vectoring or Gfast performance testing). Telebyte’s superior transparency delivers excellent crosstalk accuracy. Ideal for ID-337 Gfast Certification and TR-249 VDSL2 Vectoring testing.

    Now you can have a flexible cable farm with micro-interruptions that is easy to automate and configure. Also supports Reverse Powering for Gfast.

    Also supports G.hn Access Wave 2 testing.

    Configurations may be expanded by adding channel expander units, allowing users to scale the number of pairs that can be switched from 24 to as many as needed, in groups of 24. In addition, segment extender units can be jumpered together to add more line segments. Flexibility is further enhanced by allowing each unit to be configured for multiple vectoring groups as well as co-located and non-co-located configurations. This scalability optimizes your CAPEX budget.
