Are you considering replacing your router? If your router is more than 5 years old, has connection issues, or if you just want to improve your range and speed, it may be time to replace your old router. Don't w. [pdf]

How to measure the extinction ratio of fiber optic arrays

How to measure the extinction ratio of fiber optic arrays

IEC 61280-2-2:2012 describes a test procedure to verify compliance with a predetermined waveform mask and to measure the eye pattern and waveform parameters such as rise time, fall time, modulation amplitude and extinction ratio. The PEM-400 is an instrument developed for high-volume testing of the polarization extinction ratio (PER) of polarization maintaining (PM) components such as fiber array units (FAU) and external laser small form-factor pluggables (ELSFP). It is defined as the ratio of the maximum to minimum optical power levels, typically expressed in decibels (dB). [pdf]

How to Understand Building Electrical Distribution Boxes

How to Understand Building Electrical Distribution Boxes

This guide breaks down everything you need to know about electrical distribution boxes in plain English. We'll explain what they are, the different panel types you'll encounter, NEC 408 requirements that govern their installation, and common applications for each type. Think of it like a conductor in an. A distribution box, also known as a distribution panel or board, is a cabinet that holds electrical parts used to supply power to multiple circuits within a system. It acts as the central point where electricity distribution is managed inside a building. [pdf]

How to connect an 8-core fiber optic cable to a surveillance system

How to connect an 8-core fiber optic cable to a surveillance system

All you need here is a fiber optic cable and connector along with digital converter. Usually, a multimode, double stranded cable would be good. Ensure there are no splices in the camera. In this video, we walk you through a real-world IP camera installation project that involves setting up a network for 10+ cameras across a 150-meter distance between a garage and a control room. Often the camera will be located remotely and outdoor-rated or direct burial (armored) fiber will be required. Complex installations involving. [pdf]

How to ground a distribution box if it doesn t have a neutral wire

How to ground a distribution box if it doesn t have a neutral wire

The most common and simplest solution for an ungrounded circuit is to install a Ground-Fault Circuit Interrupter (GFCI) device. A simple three-light receptacle tester is the quickest way to check a three-prong outlet, using a pattern of lights to indicate common wiring issues, including an open ground. There is no ground bus bar present. This method works if you have a conventional. Alright so if I keep the hot wires ground connected to the screw and wire nut the neutrals ground with the fixture ground I should be good? The neutrals are not connected to ground at anyplace other than the main panel. Preparation: First, you need to prepare some necessary tools, including grounding wire, grounding rod, voltmeter, insulating gloves and insulating tools. [pdf]
