摘要： An apparatus and method for bus interface for matching an optical module are provided. The interface apparatus connected to a bus includes a bus matching unit which performs a control operation for interfacing with the bus, receives digital data and a part of control signals, which are transmitted from the bus, into the bus interface apparatus, and outputs digital data and control signals of the bus interface apparatus, corresponding to the data and the control signals, to the bus; an optical matching module which includes a sending terminal for converting a digital signal to an optical signal to output the optical signal and a receiving terminal for converting an input optical signal to a digital signal; and a matching controller which delays a signal exchanged between the bus matching unit and the optical matching module by a predetermined time to drive the signal, using a predetermined time required for converting a digital signal to an optical signal or vice versa in the optical matching module and signals including a basic synchronization clock signal for operation of the bus. In the bus interface apparatus, when data is written through an optical module interface to a bus, a signal indicating that data can be written is delayed by a predetermined time to be driven, thereby solving the inconvenience of not transferring the exact data due to delay time which may occur from conversion between digital and optical signals in an optical module interface. This greatly improves convenience in a system integration by easily matching an optical module to the system.
