Description

Technical Field

[0001] The utility model relates to the technical field of isolators, in particular to a high-power online isolator. Background Art

[0002] In-line isolators are special passive optical communication devices whose main function is to allow optical signals to pass in one direction while blocking them from passing in the opposite direction. This directional characteristic makes in-line isolators widely used in optical communication and optical measurement.

[0003] The online isolator is connected to the optical communication system to ensure that the optical signal will not be interfered by the reverse optical signal during the transmission process. When the high-power isolator is used, a large amount of heat is accumulated inside it. The electronic components are in an overheated environment for a long time, which will lead to a short service life. There are certain shortcomings in its use. For this reason, we propose a high-power online isolator. Utility Model Content
