This paper presents the conservation laws for optical cubic–quartic solitons in birefringent fibers where the governing model is Sasa–Satsuma equation. The multiplier approach reveals the conserved densities to the model. The conserved quantities are finally computed from these soliton solutions that were reported earlier.
