Description

Technical Field

[0001] The utility model relates to the technical field of optical power detection equipment, in particular to a portable optical power meter. Background Art

[0002] In fiber optic systems, measuring optical power is fundamental, much like a multimeter in electronics. Optical power meters are a common and often used instrument for fiber optic measurements. By measuring the absolute power of a transmitter or optical network, an optical power meter can evaluate the performance of optical equipment. When used in conjunction with a stable light source, an optical power meter can measure connection loss, verify continuity, and help assess the transmission quality of a fiber optic link. However, existing optical power meters still have certain drawbacks, such as:

[0003] In order to facilitate carrying, existing optical power meters are usually equipped with a hanging rope. However, during the test process, the hanging rope affects the grip and even becomes entangled, affecting use. In addition, existing optical power meters generally use a protective cover or protective cap to cover the test head for protection when idle. If the optical power meter is accidentally dropped during use, it cannot be protected, resulting in poor protection performance. Utility Model Content
