Abstract
To provide an FRP (Fiber Reinforced Polymer) tension member for a drop optical fiber cable in which a foaming phenomenon is eliminated. SOLUTION: A drop optical fiber cable 1 is provided with fiber cores 2 and 3, tension members 4, a supporting wire 5 and a main cladding 6. The tension members 4 are made of FRP tension members having an FRP section in which reinforced fibers are combined by means of a thermosetting resin. In the FRP tension members, the amount of residual styrene monomer in the FRP portion is required to be equal to or less than 0.018 weight% (with respect to the FRP section). When the amount of residual styrene monomer exceeds the above amount, the residual styrene monomer contacts with the melted main cladding when sheathing the main body in the production process of the drop optical fiber cable, the residual styrene monomer is volatilized and abnormality such as foaming in a cladding section and the main cladding section occurs. In order to control the amount of residual styrene monomer under a preset value, proper selection of a highly reactive thermosetting resin and a highly reactive catalyst, a proper setting time and a post processing after the setting or the like are all it takes.
