2 Brief description
The visual red light source is used to screen optical fibres when troubleshooting and
for fibre classification.
The red light source allows individual optical fibres to be localised in bundles of fibres.
Any light escaping from the fibre sheath due to crushing, broken fibres or at splices,
and other occurrences, can be identified visually.
Optical fibres with a 2.5 mm connector (SC and FC types) can be inserted.
Both APC (8°) or UPC and PC (0°) connectors can be inserted.
Important – please note:
Never look directly into the beam of red light. If diffuse, unbundled light is
observed at a viewing distance of approx. >40 cm, this is quite safe under
normal conditions.
Do not look into the red light beam using optical loupes or lenses, or
optical fibre microscopes, either. A concentrated power that is
hazardous can be generated by bundling the light.
Only switch on the red light source once the patch cable or the optical
fibre has been inserted into the device.
Observe the red light that is emitted at the required minimum distance.
Do not leave the red light source switched on without supervision, and
instead switch it off immediately after successfully troubleshooting, and
secure it against accidental and unauthorised activation.
The range of the red light is visible for up to approx. 10 km for single mode fibres
G652 or G657. Optical splitters and other attenuation occurrences shorten the range
Please press and hold the left button for approx. 3 seconds to switch it on. The
same is done to switch it off.
To generate a 2 Hz pulse mode, press the right button (
Fn ). Pressing it again
switches off 2 Hz pulse mode again.
