Two in one
Hradil Spezialkabel introduces a new hybrid cable including both a fiber optic (FOC) and a copper cable. This specific broadband hybrid cable adds up to Hradil’s FOC business segment and combines two benefits. On the one hand, the optical fibers enable high data rates for the network layer whereas the “conventional copper cores” ensure the power supply and carry triggers and signals for the connected applications.

Using the keyword „Fiber to the home“, the optical fiber technology has found its way into the private customer field. The ultimate ambition is that all voice and image data be broadcasted without loss to the end-user. This requirement constitutes one of the main FOC properties which Hradil exploits in its new hybrid cable. The optical fibers enable a lossless transmission of the optical signals over a great distance without repeater and therefore make demanding applications like e.g. 3D-television (far above 100Mbit/s) possible. Jürgen Albrecht, Hradil product designer for special cables explains: “There is no way a copper cable could keep up with these advantages. The optical fiber technology offers a full symmetrical bandwidth, for example for the down- and upload of data”. In addition, its price is much cheaper than the copper technology, which constitutes another plus.


Advantages of the optical fiber technology (versus copper cable)
Opportunity of a combined installation together with other supply lines
  • Electromagnetic immunity (no EMI)
  • Crush resistance, no interference radiation,
  • No bandwidth loss resulting from the distance due to inductive reactance, capacitances or impedances
For the optical part of this hybrid cable, Hradil focuses on so-called graded index fibers. Graded index fibers (GI) offer a broader bandwidth than step-index-fibers and are available in different core diameters. They are typically suitable for the connection of interfaces like for example in street cabinets, building and home connections with high bandwidth.
