[0002] Wavelength division multiplexers can transmit multiple optical signals of different wavelengths simultaneously in the same optical fiber, thereby improving the bandwidth utilization of optical fiber transmission. Wavelength division multiplexers are divided into two types: dense wavelength division multiplexers (DWDM) and sparse wavelength division multiplexers (CWDM), which are designed for different application scenarios and needs. Through wavelength division multiplexing technology, efficient transmission and management of multiple optical signals in optical fiber communication networks can be achieved.

[0003] A wavelength division multiplexer is generally provided with a large number of optical fiber cables inside. During installation and use, the optical fiber cables may become entangled, causing inconvenience to the inspection and maintenance of the wavelength division multiplexer. Therefore, a positioning structure for a wavelength division multiplexer is proposed to solve the above problem. Utility Model Content

[0007] Furthermore, a clamping assembly is provided on the positioning column, and the clamping assembly includes a first clamping plate, a second clamping plate, a buckle and a second clamping block. The first clamping plate is fixedly installed on the front side of the outer peripheral wall of the positioning column and below the positioning groove, the second clamping plate is movably installed on the top of the first clamping plate, the second clamping block is fixedly installed at the right center of the second clamping plate, and the buckle is fixedly installed at the right center of the first clamping plate, and the buckle matches the second clamping block.

The clamping block can clamp the optical fiber cables. In this way, the optical fiber cables in the box can be fixed on different positioning columns and positioning grooves respectively, effectively avoiding the situation where the optical fiber cables are entangled together.
