A resin composition for an optical fiber is provided which can be sufficiently cured even in high-speed processing (at a low light energy dose) to obtain a cured article having a Young's modulus suitable for use for an optical fiber, and also causes neither increase in viscosity nor deposition of solids in storage for a long period or in storage at a high temperature and can be easily coated even after such storage. A coated fiber and an optical fiber unit, which use the resin composition are also provided. The composition contains a radical polymerizable compound (A); a photopolymerization initiator (B); a sulfide (C) represented by the formulas: R
