Advantages and Disadvantages of Glass Optical Fiber


  • Glass fiber cables can be used in high-temperature applications like furnaces, ovens, and condensers in large engines, as well as in extremely low-temperature areas such as cold storage warehouses.
  • Since glass cores are efficient at transmitting light and allow for significantly higher transfer speeds, glass optical fibers can be used over long sensing distances.
  • Glass optical fiber enables you to use a photoelectric sensor in areas where you wouldn’t normally be able to use them. With this advantage, you can choose sensors with a wide range of housings, mounting styles, and features for your specific application.
  • Since glass fiber optic cables are thin and light, they are optimized for small spaces and small targets.


  • The installation of glass optical fibers requires highly trained technicians, and the tools and equipment for fiber termination are usually expensive.
  • The core diameter of glass fiber is very small, hence it has higher technology requirements to couple light into the core region, such as light sources.
  • Glass optical fibers are fragile and more possible to break if not handled properly.
