FiberOptic connector


  • Robust
  • Optical performance
  • Easy cleaning


Fischer FiberOptic connectors and cabling solutions offer the best quality and stability needed for an optical link, combined with easy mating and easy field cleaning. They will perform perfectly in harsh and extreme environments and have a high ingress protection of IP68 when mated, and IP67 unmated.

Reduced insertion and return losses

The Fischer FiberOptic Series is well-known for its robust and faultless optical performances in any conditions. UPC & APC polishing reduces insertion and return losses, making devices more secure, while IP68 sealing provides highly valuable device protection.

Push-pull locking system

The push-pull locking system allows quick and easy connections and disconnections, making these connectors ideally suited for outdoor environments. The removable sleeve holder (monoblock mate adapter) ensures that end faces can be cleaned easily, keeping electronics in top condition.

Fischer FiberOptic Series - Easy mating


Fischer FiberOptic Series operates effectively at cryogenic temperatures, with a minimal effect on insertion and return losses, and on optical and sealing performance. It provides an excellent baseline measurement for further testing and a good starting point for investigating fiber optic interconnect solutions for other cryogenic applications.

Liquefied natural gas (LNG) pipelines, where temperatures can drop to approximately -180°C, are another example of an application that depends on robustness to ensure reliable, long-term performance. As demonstrated in the CERN tests, optical fiber can be used to monitor temperatures along the pipeline even in extreme cold.

The test results confirm the ruggedness of our connectivity solution, which can deliver precision optical performance in cryogenic and other extreme applications.

Easy Field Cleaning 

Fischer Connectors can offer a fiber solution that is extremely quick and easy to clean thanks to a removable mono-block mate adapter and to the possibility of rinsing the unmated connectors freely under water or in an ultrasound bath.
