  • Pros and cons of the most common fiber optic connectors
  • Importance of the self-centering ferrule
  • Pros and cons of the two main connector styles – FC and SMA
  • Importance of physical contact and polishing angle in regard to coupling efficiency and back reflections

 

 

There are two main categories of fiber-coupled laser diodes, pigtailed and detachable. The pigtailed approach provides significant advantages when it comes to alignment stability, mainly when dealing with single-mode fibers which, typically have a core diameter of less than 10 microns. By comparison, it is impossible to ensure that detachable fiber-optics will line up in the same spot, each time the fiber is connected. Therefore, reducing the overall coupling efficiency of the system. However, unless the pigtail is fusion spliced to another fiber, for both pigtailed and detachable fibers, it is required that at least one end of the cable be terminated with a fiber-optic connector. As a result, it is essential to understand the different types of fiber connectors used with fiber-coupled diode lasers as well as their pros and cons.

After reading this white paper, you will come away with an in-depth understanding of the optomechanical structure of fiber optic connectors, their variants and tolerances, and which of these will better suit your needs.
