SynopsisIn fiber optics, a reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength-division multiplexing (WDM) system at the wavelength layer. This is achieved thr.....
SynopsisThe damped coupling consists of a main half-coupling, a slave half-coupling and a sealed housing. The damping coupling uses hydraulic fluid instead of conventional elastic materials, and the damping effect is achieved by the flow of hydraulic fluid between the.....
SynopsisFlat-break air breakers are completely renewable. This means that they can be rebuilt. Any damaged or broken parts can be repaired or replaced. It has six main components: the disconnecting connection (stinger), the contact assembly, the interrupter chamber, t.....
SynopsisSpectroscopic film thickness measurement systems for measuring film thickness, refractive index, reflection, transmission and absorption spectra of films and coatings. The global Spectroscopic Film Thickness Measurement System market was valued at US$ 15.....
SynopsisA Customisable Digital Polarimeter is an instrument used to determine the spin of a substance. The digital rotameter uses photoelectric detection and the principle of automatic optical zero balance for testing. The global Customisable Digital Polarimeter.....
SynopsisThe channel coil actuator consists of four bi-directional voltage controlled current sources designed to drive inductive loads. The output power has its own set of controls, indicators, inputs and outputs. Balanced differential inputs isolate the coil driver f.....
SynopsisFibre optic cable ring is a network topology in which each node is connected to two other nodes, thus forming a continuous path - a ring - for the signals passing through each node. Data is transmitted from one node to another, with each node along the way pro.....
SynopsisTransmittance-enhanced film cells offer a new optical pathway for vacuum experiments. Assembled using an optical contact process, these cells provide a high quality AR coating while maintaining a very high optical flatness in the cell wall, resulting in minima.....
SynopsisBattery separator quality control tools, to ensure the quality of the delivered rolls and to avoid conversion or end-use problems, require the use of appropriate instrumentation for quality control measurements of BSF. The global Battery Separator Qualit.....
SynopsisPolyethylene battery diaphragms, as the surface of lithium-ion polymer battery diaphragms, the presence of PiAN induced to the membrane surface by plasma modification plays a key role in improving wettability and electrolyte retention, interfacial adhesion bet.....
