Title: Plastic optical fiber and method for manufacturing the same
Inventor: MIWAKEICHI KAZUNARI
IPC: G02B6/00
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a high-performance plastic optical fiber which is low in transmission loss even when the optical fiber is damaged by a connecting stress. SOLUTION: The fiber having a core-sheath structure formed by melt spinning is subjected to thermal stretching, then to a heat treatment, by which the sheath material is melted or plasticized. The heat treatment is the annealing treatment or thermal stretching treatment to be executed by using a heating gas of >=130 to <=190 deg.C or stream of >=120 to <=180 deg.C while the fiber is maintained in a fixed length state. As a result, the plastic optical fiber of which the sheath material consists of only the region substantially free of specific double refractiveness is obtained.
