TDS RFoF1P System

RFoF1P is a 1-port RF-over-Fiber link based on our active photonic TDS probe technology. It is a miniature electrically fully isolated RF-over-Fiber probe link operating in the 100kHz – 10 GHz frequency range. It is an excellent solution for applications where traditional coaxial measurement cables and other galvanic connections to the DUT are not possible or not desirable. An RFoF1P system consists of a miniaturized electro-optical media converter (SMA to optical fiber) and a standard TDS remote unit (optical fiber to 3.5mm). The miniature media converter employs power over fiber, i.e., does not require external or battery power and can be customized and miniaturized further for OEM applications.

RFoFP1 system


TDS RFoF1P is composed of one RFoF1P and a TDS Remote Unit. 


The TDS RFoF1P system is optimized RF signal transmission over fiber optics in EM-hostile and EM-sensitive environments:

  •  Over-the-Air performance 
  • Antenna correlation measurements
  • Signal and power integrity
  • MRI signal links
  • EMP/ESD/Lightning test
  • Low-noise, long-distance interconnects
  • Timing, and frequency reference
