Optical Safety Standards

The relevant international laser safety standard is usually AS / NZS IEC 60825-2:2011 ‘Safety of laser products Part 2: Safety of optical fibre communications systems (OFCS)’ Specifically Annex D, table D.1

Equivalent USA standards are administered by the FDA (Food & Drug Administration) under 21CFR1040.10

There are two safety classes directly relevant to Kingfisher Test Equipment:

Kingfisher infra-red test sources and VFL pens are all Class 1. This means they are eye safe, with or without a microscope.

Kingfisher offer a some special high power instruments with up to Class 2M power output, and negligible extra uncoupled total emission.

Class 2 devices are visible, so the "eye aversion" or "blink" response will cause the user to look away before eye damage is caused, allowing a higher safe level.

Power meters don't emit light, but safety precautions need to be used relevant to the maximum light level that could be emitted from the fiber.
