Section 1 — General & Safety Instructions
You should always follow these Instructions to help ensure Against injury to yourself and damage to your equipment.
WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO
RAIN OR MOISTURE
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV System Installer’s attention to
Article 820-40 of the NEC that provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be connected to the grounding
system of the building, as close to the point of cable entry as practical.
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.
WARNING: The optical emissions from the units
are laser-based and present eye hazards. Follow
all safety precautions.
The STOP sign symbol is intended to alert you to the
presence of REQUIRED operating and maintenance
(servicing) instructions that if not followed, may result in
product failure or destruction.
The YIELD sign symbol is intended to alert you to the
presence of RECOMMENDED operating and maintenance
(servicing) instructions.
The LIGHTNING flash symbol is intended to alert you to the
presence of uninsulated “dangerous voltage” within the
product's enclosure that may be of sufficient magnitude to
constitute a risk of electrical shock.

1.2 Laser Safety Procedures
ALWAYS
read the product data sheet and the laser safety label before powering the product. Note the operating wavelength,
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 input of the device
BEFORE
power is applied. Power should never be applied without an
attached fiber input. If the device has a fiber 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 disconnect the unit
from any power source.
If you have questions about laser safety procedures, please call Blonder Tongue before powering your product.
1.1 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.
