  • Lightning protection wire with optical fiber communication line

    Lightning protection wire with optical fiber communication line

    Optical fiber cable OPGW (Optical Ground Wire) is a hybrid overhead cable that combines the role of a transmission line lightning protection conductor (ground wire) with built-in optical fibers for communications. Therefore, it is important to build a lightning protection. Building a lightning protection system for fiber optic cables is essential to safeguard the network infrastructure from potential damage caused by lightning strikes. Installed at the top of high-voltage transmission towers, OPGW replaces traditional. Although the signals in fiber cables are optical signals, most of the outdoor optical cables using reinforced cores or armored optical cables are easy to get damaged under lightning because of the metal protective layer inside the cable. What is OPGW (Optical Fiber Ground Wire)? OPGW is a.

    The function of an adjustable attenuator in optical fiber cables

    Variable Attenuators: Variable attenuators offer adjustable levels of attenuation, allowing precise control of the signal power. They are commonly used in situations where dynamic adjustments are required, such as network testing or in applications where power levels vary over time. for achieving a suitable signal level for a data receiver in a telecom system. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters.

  • Energy-efficient custom-designed optical directional coupler

    Energy-efficient custom-designed optical directional coupler

    Abstract: Directional couplers (DCs) are the basic elements for constructing various silicon photonic devices, including Mach– Zehnder switches (MZSs). Here, we propose a novel 2×2 bent directional couplers based on Bézier curves designed with an efficient semi-inverse design method. However, it is challenging due to the coupling between fibers and waveguides, which is highly sensitive. The design and fabrication of a compact, low-loss, broadband directional coupler (DC) based duplexer operating in the near-infrared (NIR) region are demonstrated. The duplexer exhibits high selectivity and coupling eficiency (CE), for target wavelengths of 1530 nm and 1653. Based on Finite Difference Eigenmode, Finite-Difference Time-Domain simulations, and experimental measurements. A directional coupler serves as an essential passive component in integrated photonic systems, allowing precise splitting or combining of optical signals between two closely. Directional couplers are essential components in integrated photonics.
