  • United States Dense Wave Division Multiplexing Market by Manufacturers, States, Type and Application, Forecast to 2022
    Published: 21-Aug-2017        Price: US 4480 Onwards        Pages: 118
    Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. The technology creates multiple virtual fibers, thus multiplying the capacity of the physical medium. Scope of the Report: This report focuses on the Dense Wave Division Multiplexing in United States market, to s......
  • Asia-Pacific Time Switch Market by Manufacturers, Regions, Type and Application, Forecast to 2022
    Published: 21-Aug-2017        Price: US 4480 Onwards        Pages: 116
    "A time switch (also called timer switch or simply timer) is a timer that operates an electric switch controlled by the timing mechanism. A time switch is a device that has a built-in mechanical or electronic timer that turns an electrical circuit on and off at certain times of the day. The electrical current typically is used to perform a task that otherwise would be done by a person. Time Switch work in a variety of areas, such as irrigation or other water pumps, indoor or outdo......
  • Asia-Pacific Reed Switch Market by Manufacturers, Regions, Type and Application, Forecast to 2022
    Published: 21-Aug-2017        Price: US 4480 Onwards        Pages: 119
    Reed Switch consists of a pair of ferromagnetic reeds, which overlap at their free ends (contact area) at a very small distance and are hermetically sealed in a glass tube. When in the presence of a magnetic field, the reeds become magnetized to opposite polarity, thus attracting each other and closing contact. Like many other great inventions, reed switches were born at Bell Laboratories, invented there in the mid-1930s by Walter B. Elwood. Today, reed switches are still in common uses. ......
  • Asia-Pacific Non-Grain Oriented Electrical Steel Market by Manufacturers, Regions, Type and Application, Forecast to 2022
    Published: 21-Aug-2017        Price: US 4480 Onwards        Pages: 116
    Electrical steels are distinguished by their excellent electro-magnetic properties. There are two major types of fully processed electrical steels: grain-oriented (GO) and non-oriented (NO). Non-oriented electrical steel features homogeneous magnetic properties in all directions. They are widely used as iron core materials in rotating machines ranging from large power generators to tiny precision electric motors. They are also used in the iron core of small power transformers. Sco......
  • Asia-Pacific KNX Products Market by Manufacturers, Regions, Type and Application, Forecast to 2022

    KNX Products (Konnex) is the worldwide standard for home and building control. The standard is based on the communication stack of EIB but enlarged with the physical layers, configuration modes and application experience of BatiBUS and EHS. KNX Products defines several physical communication media: Twisted pair wiring (inherited from the BatiBUS and EIB Instabus standards); Powerline networking (inherited from EIB and EHS - similar to that used by X10); Radio (KNX Products-RF); Infrared; Etherne......
  • Global Static Random Access Memory (SRAM) Market by Manufacturers, Countries, Type and Application, Forecast to 2022
    Published: 21-Aug-2017        Price: US 3480 Onwards        Pages: 119
    This report studies the Static Random Access Memory (SRAM) market, SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor, SRAM does not have to be periodically refreshed. Static RAM provides faster access to data and is more expensive than DRAM. SRAM is used for a computer's cache memory and as part of the random access memory digital......
