Plastic Optical Fiber RAYTELA™ What is Optical Fiber?RAYTELA™

Optical fiber has a 2-layer construction, with a core material and an outer cladding material. By making the refractive index of the core higher than that of the cladding, a total reflection of light occurs at the intersection between core and cladding that is greater than the critical angle. The light entering the core is contained inside the core by this total reflection, and transmitted.


Types of Optical Fiber

Optical fiber can be split into the following types based on material and construction.

About Plastic Optical Fiber

Toray Plastic Optical Fiber RAYTELA™ is a multimode/step index optical fiber with low loss and high reliability. The polymethyl methacrylate (PMMA) that makes up the core portion uses a clean polymer made with integrated manufacturing from monomer to fiber production. A special fluorine containing polymer is used for the cladding.

Comparison with electrical wire
  1. Wide transmission band
  2. Noise Resistance
    Is not affected by external electromagnetic interference
  3. Explosion-proof
    No short circuits
  4. Lightweight
  5. Complete prevention of crosstalk
Comparison to Quartz Optical Fiber
  1. High Light Transmission
    Large diameter, high core proportion
    100 µm: 96% (Quartz type 125 µm: 0.6%)
  2. Flexibility (not easily broken)
  3. Handling
    Does not require special technology/tools
  4. Low Cost Light Transmission System
    Red LEDs, resin connector
