TEST APPARATUS FOR TESTING DEVICE UNDER TEST HAVING OPTICAL COUPLER, TEST METHOD FOR TESTING DEVICE UNDER TEST HAVING OPTICAL COUPLER BY TEST APPARATUS AND DEVICE INTERFACE

摘要

PURPOSE: A test device, a test method, and a device interface are provided to observe the light collecting position, accuracy, and imbalance of an optical coupler in a tested device. CONSTITUTION: A test device comprises a substrate(110), an optical transmission line(120), and a lens unit(130). A tested device(10) is mounted on the substrate. The optical transmission line transmits an optical signal. The lens unit is installed in order to be faced with an optical coupler on the substrate. The optical signal from the one direction from the ends of the optical transmission line and optical coupler is collected to the other direction by the lens unit.
