Specially, the invention is related to method and device for testing performance of new type self-defined photoelectric interface of Ethernet (PIE). An adjustable optical attenuator (AOA) is setup at sending direction of optical port of Ethernet. Data packet sent by the Ethernet data test logic module (EDTLM) passes AOA, which adjusts degree of decay of the sent light, and measures light receiving sensitivity of optical fiber transceiver. A light coupler is setup at receiving direction of optical port of Ethernet. The input light passing through the light coupler is split into two routes: one route is sent to light power test module; and the other route is sent to EDTLM at same time. The invention tests performance of optical interface, and tests luminescence power of device to be tested. The invention realizes testing performance of PIE through 'one key pushed'. Features are: easy of operation, quick test, and low testing cost.

The invention belongs to the technical field of hydraulic damper testing, and relates to a transverse anti-seismic test method for a nuclear-grade hydraulic damper, which comprises the following steps of S1, performing pre-inspection on the size and the appearance of each test tool; S2, performing a pre-test performance test on the performance of each test tool; s3, installing the damper in a test tool, installing the test tool on a test bed, and then enabling the test bed to conduct transverse vibration acceleration on the damper; s4, sequentially installing the damper in each test tool for the step S3, and recording the vibration frequency and amplitude of each test tool; S5, performing post-inspection on the size and the appearance of each test tool; and S6, performing a post-test performance test on the performance of each test tool. Through the test, enough data can be obtained, the excellent transverse anti-seismic performance of the damper can be effectively judged according to the data, the test difficulty is reduced, the operation is simple, and the use is convenient.
