POF stands for plastic optical fiber with the term plastic being used a vulgarization for polymer materials. The 1mm fiber diameter is about 500 times thicker than a glass optical fiber.96% of the cores cross section conducts modulated light for data transmission similar to glass optical fiber applications.he purpose of the project was to create an external USB audio card, which could be able to: 1) serve as usual external USB audio card with headphone/line output and audio line input. 2) can transmit the digital audio data at relatively long distance (20m -100m).
