Abstract:
A bus interface apparatus, connected to a bus, for matching an optical module, the bus interface apparatus comprising:a bus matching unit which performs a control operation for interfacing with the bus, receives a first digital signal including first data and first control signals, the first digital signal being transmitted from the bus into the bus interface apparatus, and outputs a second digital signal including second data and second control signals of the bus interface apparatus, to the bus; an optical matching module which includes a sending terminal for converting the first digital signal to an optical signal to be output and a receiving terminal for converting an input optical signal to the second 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 based on a time required for the optical matching module to convert the first digital signal to the optical signal to be output or to convert the input optical signal to the second digital signal and using a basic synchronization clock signal for operation of the bus.
