Embodiment Construction
[0028] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] like figure 1 Shown, a kind of method that is used for Pigtail TOSA three temperature test, comprises the steps:
[0030] Step 1: Design a fixture for the Pigtail TOSA three-temperature test; the upper part of the main body of the fixture is a square structure, including the bottom plate, left panel and right panel, the front and back are empty, and it is also fixed on the main body The chopping head that can be pressed down on the upper part of the bottom plate;
[0031] Step 2: Place the laser to be tested wrapped in heat dissipation mud directly under the chopping body on the bottom plate of the main body, align it, add wires and optical fibers to lead out from the heat dissipation mud, and pass through the empty parts in the front and back of the main body ;
[0032] Step 3: Gently press down the chopping body, the c...

The invention provides a Pigtail TOSA three-temperature test method and device, and the method comprises the steps: 1, designing a jig, the upper part of a main body of the jig is of a square structure, the jig comprises a bottom plate, a left panel and a right panel, the front surface and the rear surface of the jig are hollow, and the jig further comprises a chopping head body which is fixed at the upper part of the bottom plate of the main body and can be pressed down; step 2, placing the tested laser wrapped by the heat dissipation mud under the chopping head body on the bottom plate of the main body, aligning, adding a wire and an optical fiber to lead out from the heat dissipation mud, and penetrating out from the hollow parts in the front and back of the main body; 3, the chopping head body is slightly pressed downwards, the heat dissipation mud is sunken, the chopping head body is fixed through a locking screw, and testing can be conducted; and step 4, putting the whole jig into a heating box after the tested laser is put, and carrying out three-temperature test. The three-temperature test fixture is simple in structure and simple in operation, solves the heat dissipation problem of three-temperature test, and can quickly fix a laser product, thereby greatly ensuring smooth three-temperature test, and ensuring the productivity.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to a method and device for Pigtail TOSA three-temperature testing. Background technique [0002] In the production process of Pigtail TOSA products, a reliability test is required. The three-temperature test is to test whether the laser performance is stable at three temperatures at -5°C, 0°C and 85°C. The test is to use the finished laser, and it needs to be powered and received. Among them, the heat dissipation and fixing of the finished laser are technical difficulties. At present, there is no effective test method and fixture, so the three-temperature test is not effective and wastes resources. In order to complete the test simply and quickly, it is urgent to design supporting fixtures for auxiliary testing. Contents of the invention [0003] In order to solve the technical problems raised by the background technology, the present invention provides a method a...
