Introduction
Possibility of personal injury. Never look directly into an unterminated
fiber-optic connector unless it is absolutely known that no optical power is
being emitted by the connector.
Possibility of personal injury. Never look into a broken optical fiber cable
unless it is absolutely known that no laser radiation is present.
Possibility of personal injury. Never look at an optical fiber splice, cable, or
connector unless it is absolutely known that no laser radiation is present in
the fiber. Laser radiation can come from a fiber-optic transmitter, an Optical
Time Domain Reflectometer (OTDR), or other optical test equipment.
Possibility of personal injury. Never look directly into an unterminated
optical connector or cable with a magnifier/microscope unless it is
absolutely known that no laser radiation is being emitted from the connector
or cable. A magnifier or microscope greatly increases the laser radiation
hazard to the eyes.
Possibility of personal injury. This system normally operates as a Class I
Laser Product (no hazard). However, during servicing operations, when
optical connectors are being connected, disconnected, or handled without
dust covers, it is possible to be exposed to Class IIIb laser radiation, which
can cause eye damage.
Possibility of personal injury. Everyone within a 10-foot radius of an
unterminated optical fiber or connector that is connected to a powered
transmitter must wear laser safety goggles or eye shields.
Laser safety goggles or eye shields are not required if the following
2.6
work rules are strictly followed:
1. Always remove electrical power from fiber-optic transmitters before
disconnecting fiber-optic connectors in the path between the
transmitter and the receiver.
2. Never connect an unterminated optical cable to a fiber-optic
transmitter. Always connect fiber-optic cables to fiber-optic receivers,
test sets, or some other termination first.
