Instrument for testing the depth of optical cables

An Optical Time-Domain Reflectometer (OTDR) is a specialized tool used in fiber optic networks for characterizing and troubleshooting optical fibers. Testing fiber optic components and cable plants requires making several measurements with the most common measurement parameters listed in the Table below. Optical power, required for measuring source power, receiver power and, when used with a test source, loss or attenuation, is the most. PFO supplies instruments to test and measure the performance of optical fibers and fiber-optic cables – the backbone of the telecommunications industry. Offering flexible configuration of products to fulfil the typical demands for testing to the current global standards. This category includes OLTS certifiers, OTDRs, optical power meters, light sources, and visual fault locators. [pdf]

Electrical cable trays in explosion-proof locations

Electrical cable trays in explosion-proof locations

Cable Trays have been permitted in the hazardous (classified) locations in the National Electrical Code for Class I (flammable vapor and gases) since the 1978 NEC and have been used extensively in chemical plants, refineries, and other types of facilities. This article is about code requirements. Let's break down what you need to know about explosion-proof requirements for cable trays in these environments, keeping it simple and clear. Chemical plants have risks like explosive gases, dusts, or vapors. However, when it comes to enforcement, only the standard approved for the geographical area may be utilized. Hazardous locations are defined in Article 500 of the National E ectrical Code® (NEC®) 2020. Cable must ha minated with listed fittings. [pdf]
