Fischer FiberOptic Series

Take fiber optics onto the field without any compromise on sealing, cleaning and performances



With the worldwide demand for increased bandwidth, data speed and high-quality audio/video, the use of fiber optics has been growing exponentially – and so has design engineers’ need for reliable optical connectivity solutions. And when the latter combine performance and quality with robustness and usability, they enable engineers to design devices that can be used in all sorts of indoor and outdoor environments. The Fischer FiberOptic Series offers robust and faultless optical performances in any conditions. Combined with easy use, cleaning and maintenance.

Product range

Fischer FiberOptic Series

The FiberOptic range features a wide choice of body styles to fulfill all your integration needs. Pre-cabled solutions provide maximum performance and time saving.


The single fiber optic connector (FO1) is a miniature, rugged connectivity solution especially designed to meet the growing market need for higher data transmission rates over long distance, while reducing space and guaranteeing performance. For example, it can be integrated into custom assemblies for instrumentation and sensing applications.

  • Available with one (FO1), two (FO2) or four (FO4) optical channels
  • Multimode with UPC polishing (Ultra Physical Contact)
  • Single mode with either UPC or 8° APC polishing (Angled Physical Contact)

Fischer FiberOptic Hybrid

The FiberOptic hybrid connector with two optical channels and two electrical contacts is perfectly suitable for demanding applications where space saving is essential.

  • Available with four channels (FO4): 2 optical channels and 2 electrical channels
  • Multimode with UPC (Ultra Physical Contact)
  • Single mode with either UPC polishing (Ultra Physical Contact) or 8° APC polishing (Angled Physical Contact)
  • Electrical contacts: current 10 [A] (IEC 60512-5-2-5b) and rated voltage 400 [V] r.m.s. (EIA-364-20-B)
