POF is overcoming silica in bit rate

The great advantage of the perfluorinated (PF) polymer base graded index polymer optical fiber ( GI POF) in bandwidth was clarified in detail. The PF polymer base POF has the potential of achieving the highest bit rate among existing physical media including even silica fiber, since the material dispersion of the PF polymer is lower than those of silica and other polymer materials. Therefore, more than 10 Gb/s bit rate transmission for 10giga Ethernet can be achieved by the POR. Campus LAN based on the PF polymer base GI POF has been actually installed in Keio University since last April. The system performance is briefly introduced in this paper.
