A Radio-Over-GI-POF Transport System

A novel radio-over-graded index-plastic optical fiber (GI-POF) transport system is proposed based on vertical-cavity surface-emitting lasers (VCSELs) and light injection-locking technique. Comparing with other light sources, VCSEL provide a good balance between its cost and quality for intrabuilding network applications. To further enhance its transmission performance, we are the first one to integrate VCSELs with light injection-locking technique in radio-over-GI POF intrabuilding network. Impressive upgrading of third-order intermodulation distortion to carrier ratio, spurious-free dynamic range, error vector magnitude, and bit error rate were experimentally obtained and discussed in the paper.
