Preliminary research on decreasing the loss of PMMA plastic optical fiber

The influence on the loss of plastic optical fiber (POF), which was caused by diverse initiators, antioxidant monomer and the technology of POF's cladding, was researched by us in this paper. We found that, the loss of POF could be decreased by using a new initiator, a antioxidant monomer and a new material of cladding. The POF, whose lowest loss was 192dB/km (650nm) corresponded with the loss level of the congeneric overseas products (about 200dB/km), was prepared in our experiment.
