Definitions

  • the present invention relates to physical connection technology in the field of optical communications, and more particularly to a plastic optical fiber connector.
  • Plastic optical fiber (POF, Polymer Optical As an alternative to quartz fiber, Fiber) is a low-cost, lightweight, and easy-to-install data transmission medium. It is especially suitable for systems with short distances, small and medium capacity, and many connectors (such as access networks). Compared with multimode quartz fiber, plastic fiber is softer, easier to install and maintain. It is especially important that the POF core diameter is usually 0.5mm or larger, while the multimode quartz fiber core diameter is 62.5 microns or 50 microns. 10 times POF connection alignment is easy. For a stepped POF with a core diameter of 980 ⁇ m and a graded POF with a core diameter of 500 ⁇ m, even a ⁇ 30 ⁇ m offset in the connection does not seriously affect the coupling loss. (Approx. 0.03dB increase in loss), inexpensive injection molded connectors can be used, significantly reducing the overall cost of the system.
