Optical module heat dissipation VC liquid cooling
A liquid-cooled optical transceiver is a high-speed module that incorporates liquid cooling technologies (such as cold plates or microchannels) into traditional optical modules to achieve efficient heat dissipation. It not only effectively reduces energy consumption. As pluggable modules scale to 400G and beyond, thermal management becomes a primary reliability constraint. This article explains contemporary thermal strategies for OSFP modules — from fin geometry tuning to detachable heatsink covers — and maps measured performance to practical deployment steps. In highly integrated environments like NVIDIA's GB200/GB300, high-speed optical modules are not only vital for data transmission but also major heat sources. The liquid cooling structure comprises a heat dissipation plate (100) and a heat conduction layer (200), wherein the heat dissipation plate (100) comprises a cooling liquid input port (110) and a cooling liquid output port.

Fiber Optic Grating Liquid Level Measurement
In this paper, we present a polymer optical fiber (POF) Bragg grating (FBG) to measure liquid level based on Archimides' law of buoyancy. The sensor consists of polymer 3D-printed rods with different radii attached to the fiber terminal containing an FBG. When the temperatures of the liquid and the gas are different, the liquid level can be. In this paper, we present a fiber sensor using a fiber Bragg grating encapsulated in a half-polymer-filled metal cylinder for measuring liquid level variation.
