2 FRRA Series
Instruction Manual
TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER FROM THIS UNIT.
NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
Safety Precautions
The optical emissions from the units are laser-based Class IIIb, and may present eye hazards if improperly used.
NEVER
USE ANY KIND OF OPTICAL INSTRUMENT TO VIEW THE OPTICAL OUTPUT OF THE UNIT
. As always, be
careful when working with optical fibers. Fibers can cause painful injury if they penetrate the skin.
Laser Safety Procedures
ALWAYS
read the product data sheet and the laser safety label before powering the product. Note the operating wave-
length, optical output power, and safety classifications.
If safety goggles or other eye protection are used, be certain that the protection is effective at the wavelength(s) emitted
by the device under test BEFORE applying power.
ALWAYS
connect a fiber to the output of the device
BEFORE
power is applied. Power should never be applied without
an attached fiber output. If the device has a connector output, a connector should be attached that is connected to a fiber.
This ensures that all light is confined within the fiber waveguide, virtually eliminating all potential hazard.
NEVER look in the end of a fiber to see if light is coming out. NEVER! Most fiber optic laser wavelengths (1310 nm and
1550 nm) are totally invisible to the unaided eye and will cause permanent damage. Shorter wavelength lasers (e.g. 780
nm) are visible and are very damaging. Always use instruments, such as an optical power meter, to verify light output.
NEVER, NEVER, NEVER
look into the end of a fiber on a power device with ANY sort of magnifying device.
This includes microscopes, eye loupes, and magnifying glasses. This
WILL
cause permanent, irreversible burn
on your retina. Always double check that power is disconnected before using such devices. If possible, completely discon-
nect the unit from any power source.
If you have questions about laser safety procedures, please call Blonder Tongue before powering your product.
Laser safety classes for the FRRA are as follows:
Storing the Unit
If a unit is to be out of use for an extended period of time, the following steps should be taken to ensure the
preservation of the unit:
1. The storage temperature range is -20°C to +70°C.
2. A low humidity environment is preferable for long term storage.
3. All connectors should be covered with active device receptacle caps.
