Improving loss testing efficiencies through enhanced OLTS abilities

  An optical loss test set (OLTS) is a well-known device for its advantages in speed and accuracy over the more conventional light source and power meter. This makes the OLTS a great fit for applications with high fibre counts such as fibre to the home (FTTH) passive optical networks (PONs), structured cabling and data […]

Corona discharge detection using an ultraviolet imaging camera

  By using a high sensitivity ultraviolet radiation receiver, corona and ultraviolet radiation can be recorded to evaluate equipment condition through data processing and analysis. With the likely future increase in power demand and expansion of the grid, failures on high voltage equipment could increase the necessity for more preventative maintenance actions. Distribution equipment in […]

Optical considerations for LED selection

  When choosing an LED for an application, its optical properties must first be considered. Properties such as lumen output, intensity distribution, and source size must be suited to the optical system of the application. One of the first questions asked when considering a LED type relates to how bright it is, which is really […]
