  • Preventing Electric Shock from Home Electrical Distribution Boxes

    Preventing Electric Shock from Home Electrical Distribution Boxes

    Use and regularly test your GFCI outlets and plugs. GFCI is short for “Ground Fault Circuit Interrupters. ” GFCIs will prevent an electrical shock hazard by cutting off power when there has been a fault interruption in the electrical current. Ricardo Mitchell is the CEO of CN Coterie, a fully licensed and insured Lead EPA (Environmental Protection Agency) Certified construction company located in Manhattan, New York. Frayed or damaged cords are an accident waiting to happen. When the protective insulation wears down, the electrical current is exposed, increasing the risk of electric shock. Electrical shock occurs when a person comes into contact with an electrical current. The severity of the shock depends on several factors, including the voltage, the person's health, and the path the current takes through the body.

  • The power meter measured a negative optical power value

    The power meter measured a negative optical power value

    When there's loss in a fiber optic system, the measured power is less than the reference power, resulting in a negative logarithmic value and a negative dB reading on the meter. Despite the meter displaying a negative number, convention dictates referring to the loss as a positive. The measurement may be optical power from a test source, a transmitter or the input of receiver, measured in dBm, which is "absolute" power - absolute in that it refers to power calibrated to a national standard, so two people testing the same fiber output with different power meters calibrated to. An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device used for measuring the average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power. The power must be lower, of course, since we have loss, and 3dB is approximately a factor of 2, so the power the meter measured is 1mw divided by 2 = 1/2milliwatt or 0. Splitters, fusion splices, connectors and.
