Core Sense Splicer


The Fujikura 41S is Active V-groove splicer. By using Bluetooth technology, the 41S wirelessly connects to the CT50 fibre cleaver and enables a range of pioneering features that will improve the overall installation time, cost and efficiency for operators. The 41S also has the unique capability to estimate splice loss with greater accuracy, using a New Core Loss Estimation Function.

  • Easy protector positioning
  • Bluetooth capability connection
  • Core loss estimation function
  • Fast splicing time 6sec.
  • Touch panel with easy operation
  • Multi-functional carrying case with inte grated work station
