An optical fiber coating composition comprising: one or more monomers forming a first polymer chain and a second polymer chain upon polymerization; and one or more hydrogen bonding cross-linkers including a first molecule that covalently bonds to the first polymer chain during the polymerization and a second molecule that covalently bonds to the second polymer chain during the polymerization. The first molecule includes a first functional group. The second molecule includes a second functional group. The first functional group and the second functional group hydrogen bond to form three or more hydrogen bonds during the polymerization. The first functional group and the second functional group both can be a ureidopyrimidinone functional group. The first molecule and the second molecule can both be a ureidopyrimidinone (meth)acrylate. The one or more monomers can be mono-acrylate monomers, and the optical fiber coating composition can lack any multi-acrylate monomers.
