What is BS EN IEC 61315 - Fibre-optic power meters about?
BS EN IEC 61315 is a series on fibre-optic power meters. Fibre-optic power meters is a device used to measure the power in an optical signal. BS EN IEC 61315 is applicable to instruments measuring radiant power emitted from sources that are typical for the fibre-optic communications industry. These sources include laser diodes, light-emitting diodes (LEDs) and fibre-type sources. Both divergent and collimated radiations are covered.
