AWG Fiber Optic Array
Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. AWGs play a key role in DWDM systems by increasing network capacity, improving spectral efficiency and enabling high speed optical. An arrayed waveguide grating is a (typically fiber -coupled) device which can separate or combine signals with different wavelengths. It is usually built as part of a planar lightwave circuit (photonic integrated circuit), where the light coming from an input fiber first enters a multimode. A planar lightwave circuit that multiplexes or demultiplexes multiple wavelength channels in fiber optic WDM systems. The earliest MUX/DEMUX module in DWDM system is based on dielectric membrane filter TFF. Both of these are series structures.

Connecting the photovoltaic array to the combiner box
This blog begins with the structure of a PV combiner box, progressively explaining the wiring methods for PV arrays, the connection sequence of DC protection devices, and grounding approaches. Practical applications are used to illustrate how to avoid common mistakes. One of the key elements of a PV combiner box is the array of fuses. This piece will address the components required for a DC PV combiner box, how to read its wiring diagram and provide a step-by-step tutorial on how to wire it safely and efficiently. What Is a Combiner Box as Used in PV System? Wiring diagrams are a part and parcel of every electrical system. In a complete photovoltaic power generation system, the PV combiner box plays an indispensable role. Whether it's a residential rooftop solar power station or a larger-scale commercial and industrial PV system, none can function without the combiner box's critical roles in power collection. Connecting solar panels to a combiner box involves running DC wiring from each panel's output to dedicated input terminals in the combiner box, where multiple panel circuits are safely combined before feeding to the charge controller or inverter.

Russian Fiber Optic Phased Array Factory
Russia's sole optical fiber production plant, “Optical Fiber Systems” in Saransk city, has been out of operation since May 2025 due to a series of Ukrainian drone attacks, The Moscow Times wrote on February 26. They manufacture fiber optic cables that are used to control UAVs during military operations. Before the shutdown, the facility produced about 4 million. Fire in the main building of the Optical Fiber Systems company in Saransk.
