OPTICAL fibre installers face significant health and safety issues when working on active optical fibre equipment or associated cables that transmit laser or LED signals.
Risks associated with optical fibre systems arise when laser signals are used to transmit data over an optical fibre installation.
As these signals operate in the infrared region of the spectrum, they are invisible. Cabling installers are at risk of instant and permanent damage to the retina in their eyes if this signal is viewed without laser eye protection.
For telecom laser applications, LASERVISION offer a clear filter covering the whole range from 850-1700nm. The filter is available in three different frame styles.
LEDs usually operate at lower levels than many lasers. However, care still needs to be taken especially when inspecting terminations. Recently, a severe incident was reported. A cabler looked at the end of a fibre optic connector connected to an active device through a hand held fibre optic microscope. The microscope magnified the LED signal light intensity more than 100 fold, causing permanent blindness in one eye.
For LED applications, LASERVISION now offer a new model providing protection from 315-1000nm in one filter, which is available from Laser Resources .
