The Tunable Laser Source has been con
fi
gured to provide
laser radiation in the C Band of operation. (1530-1565nm) L
Band may be available upon request with a range of (1565-
1625nm). Please see the warning label in
fi
gure 1.1. This is
displayed on the left hand side of the body of the TLS. The unit
has been designed to comply with 21 CFR (Code of Federal
Regulations) 1040.10 and 1040.11, for Class 1M emission
limits. Although Class 1 levels are not considered to be hazardous, we suggest limiting exposure by
never looking directly into the optical aperture. Also, do not under any circumstance view or inspect the
laser output
fi
bers, connectors or the
fi
ber under test through collimating or focusing optics unless the
unit is turned off, batteries are removed and the power adapter is disconnected.

The FTE6000 also contains a visual fault locator. The VFL
is a Class 2 laser. Class 2 lasers are considered safe for
normal operation, the output power is below 1 milliwatt. All
Class 2 lasers emit visible light only.
SAFE USE GUIDANCE - GENERAL
A Class 2 laser is relatively weak. It normally would not
harm an eye unless a person deliberately stared into the beam. Laser protective eyewear is normally not
necessary. A Class 2 laser is not a skin or materials burn hazard.
However, even a Class 2 laser can be a distraction, glare or flash blindness hazard for pilots and drivers.
NEVER aim any laser towards an aircraft or vehicle that is in motion. This is unsafe and is illegal.
