Embodiment Construction

[0018] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0019] as attached figure 1 As shown, a re-pluggable automatic test system for EML lasers, the system includes a re-pluggable fixture and an automatic test control circuit, the re-pluggable fixture includes a socket, the socket is provided with Hollow tube, the number and position of the hollow tube match the number and position of the EML laser pins, so that the EML laser can be repeatedly plugged and unplugged on the tube base, and the automatic test control circuit is set on the re-pluggable fixture pins on the EML laser are electrically connected. In the embodiment of the present invention, the EML laser is preferably a 10G-EML laser.

[0020] Since the EML laser is electrically connected to the automatic test control circuit by inserting each of its pins in a re-pluggable fixture during the te...

Abstract

The present invention relates to the field of the optical communication technique, particularly to a repeatable plugging automatic test system and an automatic test method of an EML (Electro-absorption Modulated Laser). The repeatable plugging automatic test system of an EML comprises a repeatable plugging clamp and an automatic test control circuit. The repeatable plugging clamp includes a tube socket provided with hollow pipes, and the amount and the positions of the hollow pipes match the amount and the positions of pins of the EML, so that the EML may repeatedly plug on the tube socket. The automatic test control circuit is electrically connected with the pins of the EML arranged on the repeatable plugging clamp. Through the adoption of the invention, the test may be performed with no need for cutting the pins of the EML, and the test with multi-repeat plugging may be carried out, therefore scrapping an EML caused by cutting the pins in the production test process may be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an automatic test system and a test method for repeatable plugging and unplugging of EML lasers. Background technique [0002] In the field of optical communication technology, 10G electro-absorption modulated laser (Electro-absorption Modulated Laser, EML) is used in high-speed, long-distance communication, and its packaging form tends to be miniaturized and integrated. The EML laser integrates a laser light source and an electroabsorption modulator on the same semiconductor, which has the advantages of low driving voltage, high modulation width, small volume, and compact structure, but is expensive. In mass production of EML lasers, the production process is: coupling→laser welding→assembly→testing→cutting pins→assembling flexible boards→finished products. The purpose of this production process design is to complete the functional test before cutting the pins. If...
