Optical fibers are now the main medium for long distance transmission of telecommunication data. As such, fibers form the key backbone structure for the internet and many rapidly growing applications such as mobile telephony, email, social media and video streaming.

PE.fiberoptics Ltd (PFO) is a leader in the manufacture of test equipment for characterisation of optical fibers. Our products are used by most major fiber manufacturers in North and South America, Europe and Asia for quality control purposes at different stages including:

  1. Production of optical fibers in 24/7 manufacturing plants
  2. Characterisation of optical fiber cables
  3. Performance confirmation of installed telecommunication networks
  4. R&D for new fiber designs

The amount of data transmitted on the internet is increasing dramatically requiring rapid advances in all aspects of network technology including fibers. As a result, we work very closely with our customers to meet their evolving measurement requirements. PFO invests heavily in R&D for our products and 90% of our sales are from instruments announced in the last five years.

We export the majority of our products and have an installed base in approximately 40 countries.

Ian Mackenzie (born 1949) was the cofounder of the fiber optics division of PerkinElmer Inc in 1985. In 2003, PerkinElmer Ltd was awarded a Queens Award for Enterprise in the category of Innovation and a second Queens Award for International Trade.
