This paper presents the automatic optical power and extinction ratio control of 4.25 Gbps optical transceiver to optimize optical transmitting eye diagrams over operating temperature range. Optical eye diagrams are adjusted an optical power and extinction ratio over temperature following to quadratic equation and linear equation respectively which are calculated from the fitting curves of optical power and extinction ratio acquisition as the optical eye diagrams are optimized. The optimized eye diagrams are considered by zero hit mask margin test compliant with Fibre Channel standards.
