The paper describes a flame-retardant and fire-resistant optical cable applied in subway tunnel that emphasizes on cable design

material selection and process control.The flame-retardant and fire-resistant optical cable has passed strict testes and the results showed that the mechanical and environment performance comply design.And it also has passed the test of the fire behavior on a single cable and the test on bunched cables procedure C for flame-retardant performance

has passed IEC 60332-11/25 and 13 S 6387standard for fire-resistant performance.And the cable possess with low-density smoke and low corrosive gas released when burning in the test.
