Description

Technical Field

[0001] The utility model relates to a handheld testing device in the field of optical fiber testing, and more specifically to a handheld testing device for testing an optical switch module. Background Art

[0002] As the demand for bandwidth and cloud services continues to grow, the focus on optical fiber in data center networks is also increasing. In order to achieve longer distances, higher capacity and higher density connections, data center operators are deploying single-mode multi-fiber MPO interconnection technology. Recently, single-mode multi-fiber MPO cables have also been introduced in access telecommunication architectures such as FTTH, FTTA or C-RAN, which can speed up deployment, simplify cable management, and increase fiber panel density.

[0003] The OTDR (Optical Time Domain Reflectometer) platform equipped with MPO switch modules is a full-featured universal solution for verification, certification and troubleshooting of multi-fiber MPO cables. With just one device, field technicians no longer need to use fan-out / branch cables to efficiently test and certify MPO links.

[0004] Optical time domain reflectometer technology is a popular research project both at home and abroad. In terms of portable optical time domain reflectometer equipment, products have been launched both at home and abroad. At present, the solutions for implementing such equipment are usually large in size or independent devices. It is not possible to run multiple devices on one platform, and the software integration is relatively complex. Patent CN2021216666569 discloses a handheld test device for testing multiple modules. Although the patent realizes that the main body of the device can test multiple functions and is small in size, it is more practical and suitable for a variety of occasions and easy to carry, but it is aimed at general modules. However, for multi-core MPO optical switch modules, there is currently no small-volume, portable test equipment. Utility Model Content

Similarly, the second optical switch module is provided with a female connector on the front and a male connector on the back. The male connector on the back of the second optical switch module is connected to the female connector on the first optical switch module, so that the two optical switch modules are stacked on the device body.
