In order to improve the using life of LD and make sure the quality of transmission signal, a high performance and low-cost driving circuit was designed, which was composed of slow turn-on circuit and constant current circuit and protection circuit. The driving circuit was simulated under environment of TINA, and the result show that the circuit can meet designed requirements and offer some positive references for the research area.
