The invention relates to a UV (ultraviolet) curing fiber coating resin for a guidance optical cable, which comprises the following components in percentage by weight: 40-65% of self-initiated carboxyl-containing polyurethane acrylate prepolymer, 10-20% of pure acrylate resin, 15-35% of octadecyl methacrylate, 5-20% of acrylate monomer, 3-15% of UV-curable cellulose ester, 1-5% of photoinitiator, 1-5% of photoinitiator and 1-5% of photoinitiator. The invention discloses a photocuring adhesive, which is prepared from the following components in percentage by weight: 0.1 to 5 percent of vinyl tri-tert-butylperoxy silane, 0 to 2 percent of photoinitiator and 0.01 to 1 percent of photocuring defoaming agent, and the sum of the components is 100 percent. The UV curing fiber coating resin is rapidly cured by UV light initiation, is free of VOC emission, low in odor, good in wettability to glass fibers, aramid fibers, polyester fibers, polyethylene fibers, carbon fibers, high-strength blend fibers and the like, excel
