How to distinguish the positive and negative poles of indoor optical cables

Home / How to distinguish the positive and negative poles of indoor optical cables

Some are non-polar and function in the same way regardless of the direction of current through them. For terminals of such polarized electrical devices, the anode/cathode terminology is used, with anode being the con. According to master electrician James Hornof, for DC power, the red wire is generally positive and the black wire is usually negative. When you're dealing with electrical wiring, it's important to know which is positive and which is negative—but how are you supposed to tell them apart? The easiest way to tell is by looking at the color, but the colors mean different things depending on what kind of power is being used. By analogy, when in electronics a signal is observed across two terminals, the measurement of voltage between the terminals yields opposing signs for the positive and negative polarity.

Some electrical components are non-polar and function in the same way regardless of the direction of current through them. For example, properties of a resistor are unaffected if the wires on its terminals are swapped. Many other components, however, require a particular direction of current to operate. For terminals of such polarized electrical devices, the anode/cathode terminology is used, with anode being the con

Component Orientation and Polarity

When current flows between two points or poles, one of the poles will have more electrons accumulated than the other. The pole with fewer electrons is called the
