  • The role of liquid cooling technology in optical modules

    The role of liquid cooling technology in optical modules

    A liquid-cooled optical module helps move data fast and stay cool. It has a design that lets liquid flow inside or around it. These modules work best where normal cooling does not help, like big data centers or powerful computers. Next, let's unveil the true face of this optical module. Good heat control gives you steady performance and helps keep electronics. As a leader in optical interconnect technology, Gigalight is pioneering immersion liquid-cooling extenders and silicon photonics liquid-cooled optical modules, driving data centers toward low-carbon and high-density development.

  • Quasi-distributed fiber optic sensing technology

    Quasi-distributed fiber optic sensing technology

    Quasi-distributed sensors enhance coverage by multiplexing multiple FBGs through time-division or wavelength- division schemes, enabling efficient long-distance monitoring. Optical sensors have emerged as vital tools in modern sensing technology owing to their sensitivity, immunity to electromagnetic interference, lightweight structure, and capability to operate under harsh environmental condition, By employing optical fiber as both transmission and sensing media. The Fiber Optic Sensing Association (FOSA) is dedicated to accelerating the use of distributed and quasi-distributed optical fiber sensing technologies. Fiber optic sensing works by measuring changes in the “backscattering” of light occurring in an optical fiber when the fiber encounters vibration.

  • Application of Dense Wavelength Division Multiplexing Technology

    Application of Dense Wavelength Division Multiplexing Technology

    Dense Wavelength Division Multiplexing (DWDM): DWDM works with a greater number of channels than the traditional WDM. It can transmit over longer distances and is primarily used in large-scale networks such as those found in internet service providers and telecommunication companies. It is designed to maximize the capacity of fiber-optic cables by simultaneously transmitting multiple data signals on the same fiber. The authors have studied WDM-PONs with centralised lightwave source and direct detection, where a wavelength-reuse system is employed to transmit the uplink data by using a colourless transmitter at the optical network unit (ONU).


  • Monitor output of the head unit

    Monitor output of the head unit

    Automotive displays — which include the center display, heads-up display (HUD), and gauge instrument cluster — show key information and interactive content to the driver. The center information display is connected to the head unit, and provides navigation and other in-cabin. The flagship Pioneer and Kenwood head unit models can do rear zone but only output composite video, which is generally good enough for the application. But there are pitfalls such as not being able to do Android Auto and play a video file off USB simultaneously. Video has to be played from DVD. I have installed a chinese Pumpkin Android head unit in my Toyota Previa van and after adding an external 3G router and connecting it via an ethernet adapter and an car roof antenna I am now extremely pleased. The controller integrates functions of the traditional head unit, cluster and. An automotive head unit, sometimes called the infotainment system, is a vehicle audio component providing a unified hardware interface for the system, including screens, buttons and system controls for numerous integrated information and entertainment functions.

    Fiber optic sensing technology is divided into point-type and

    Optical fiber sensing can be broadly classified into two types: point type, and distributed type. Point-type sensors are specially processed on optical fiber lines to function as sensors. A typical example is the Fiber Bragg Grating sensor. The distributed type uses technology making the entire. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system.
