A method, an apparatus and a device for detecting an optical module, and a storage medium are provided. The method includes: constructing insertion loss ranges meeting an insertion loss specification that respectively correspond to different signal frequencies in a predetermined signal frequency range, to construct a target insertion loss region; acquiring a microstripline length, a stripline length, a via number and a connector number of a to-be-detected optical module; inputting the microstripline length, the stripline length, the via number and the connector number to a pre-constructed first model, to determine an insertion loss curve of the to-be-detected optical module in the signal frequency range; and determining that the to-be-detected optical module is unqualified if a part of the insertion loss curve is outside the target insertion loss region.

Optical module testing method, apparatus and device, and storage medium

An analysis method and an analysis system for optimization of a high-speed signal connector are provided. The method includes: setting an excess portion of each of a pin and a pad in the high-speed signal connector to be different lengths; equating the excess portion of each of the pin and the pad with an inductor and a capacitor; analyzing performance of connectors having different lengths of the excess portion of the pin and different lengths of the excess portion of the pad, and comparing performance parameters of the connectors; and obtaining a length of the excess portion of the pin and a length of the excess portion of the pad in a case of an optimal performance parameter, and cutting the pin and the pad based on the obtained lengths.
