This paper describes the design, development, and deployment of a smart distribution box enabled by the Internet of Things (IoT) with the goal of improving defect detection, power monitoring, and overall energy management in single-phase residential power applications. An IoT dashboard was used to display the most significant information in terms of voltage, current, real power, reactive power, apparent power, power factor, and energy consumption. Assembling the Distribution Box Start by mounting the circuit breakers and contactors inside the distribution box, following the manufacturer's instructions. Utilizing a NodeMCU microcontroller unit, the system integrates a 4-channel relay for load management via voice.

Typical power levels measured by an optical power meter: Telecom transmitters: 0 to +10 dBm (1 to 10 milliwatts), Receivers: -30 dBm (1 microwatt) DWDM systems with fiber amplifiers: +10 to +20 dBm (10 to 100 milliwatts), Receivers: -20 to -30 dBm (1-10 microwatt). Typical Measurement Values in Fiber Optics Here are some typical measurements in fiber optics of optical power and loss. You may want to come back to this section as you read the explanations of dB and dBm below. This falls into visible wavelength (from 400nm to 700nm) and near infrared wavelength (from 700nm to 1700nm) in the electromagnetic spectrum shown in Figure 3. Attenuation in fiber optics is the gradual loss of light signal strength as it travels through a fiber cable. When a fiber attenuates (also known as background loss), less power will be seen at the output than the input. The relationship is: 1mw=0dbm, that is to say, 2mw=3dbm, 10*lgmw is the dbm value.

An increasingly common special-purpose OPM, commonly called a "PON Power Meter" is designed to hook into a live PON (Passive Optical Network) circuit, and simultaneously test the optical power in different directions and wavelengths. OverviewAn optical power meter (OPM) is a device used to measure the power in an signal. Additionally, these may be used with attenuating elements for high optical power testing, or wavelengt.
