PLASTIC OPTICAL FIBER AND COMMUNICATION SYSTEM EMPLOYING SAME

摘要

A POF strand (11) is constituted of a core (15) as a light conducting portion, and a clad (16) for sealing the light in the core (15). A coating layer (12) is provided for covering the POF strand (11), thereby constituting a POF cable (10). The outside diameter of the core (15) is set in the range of 200-500µm, and the outside diameter of the POF strand (11) is set in the range of 750-1000µm. The POF cable (10) of 20m long is bound by means of a binding band (24) into a circle having an outside diameter (D5) of 200mm, and the coating layer is so formed as to have such a hardness as a bend occurring in the vicinity of a holding portion (23) by the self-weight of the circular portion (22) has a radius (R2) of 7mm or more when the POF cable (10) is held horizontally by the holding portion (23) with the position separated by 100m to the outside of the circular portion (22) from the binding band (24) as the end (21).
