Abstract:
A microcomputer 202 is coupled to a SFP module 101 via control signal lines 112 to 114. The microcomputer 202 monitors control signals transmitted on the control signal lines 112 to 114, and acquires, based on the result of monitoring, the condition of the SFP module 101 from a ROM 151 at a timing when a protocol chip 102 is not accessing the SFP module 101.
