Introduction
ST112 SONET Transmission Test Set 1–5
Safety Instructions
WARNING! Read and Follow all of these Safety Instructions.
Failure to do so can cause injury to the user and damage the instrument.
AC Power
The ST112 SONET Transmission Test Set is designed to sense and switch line voltages between
115 VAC (90 to 132 VAC) and 230 VAC (180 to 250 VAC) and to operate at a line frequency of
either 50 Hz or 60 Hz (47 to 63 Hz range). Never connect the Test Set to a line voltage that falls
outside these voltage or frequency ranges.
Ground the Instrument
The ST112 SONET Transmission Test Set is grounded through its AC LINE connector. Always
power the Test Set using a three-conductor power cord that is plugged into a grounded, three-
conductor outlet. If you operate the Test Set without a proper ground then all metal surfaces of
the instrument can become potential shock hazards.
Use the Proper Fuse
Always replace the AC LINE fuse using the procedure and fuse rating specified. Use a 5 Amp
SLOBLO fuse. Operating the instrument with an improper fuse will create a fire hazard.
Do Not Look into the OPTICAL Output
The ST112 SONET Transmission Test Set OPTICAL output is equipped with a high-powered
laser. Never look directly into the laser output or into an unterminated optical patch cord
connected to this output. If you do not follow these precautions, permanent eye injury can
result.
Do Not Operate in an Explosive Atmosphere
The ST112 SONET Transmission Test Set does not provide protection from static discharges or
arcing components and therefore must not be operated in an explosive atmosphere.
Do Not Remove Instrument Covers
To avoid a shock hazard and to maintain proper air flow, never operate the Test Set with any of
its outside covers removed.

Introduction
1–6 ST112 SONET Transmission Test Set
Laser Safety
WARNING! Read and Follow all of these Safety Instructions.
To prevent injury, ensure the following information is reviewed before operating this equipment.
The ST112 SONET Transmission Test Set with Options 03, 04, and 5R are Class I laser
products that comply with the United States Food and Drug Administration (FDA) Standard 21
CFR Ch. 1040.10.
The Laser radiation emitted from the ST112 SONET Transmission Test Set aperture when the
fiber optic cable is disconnected has a wavelength which is in the near infrared spectrum and is
invisible.
Safety Precautions
To avoid exposure to hazardous laser radiation, it is recommended that the following practices
are observed when operating this equipment:
•Always use service-trained personnel, who are aware of the hazards involved, to work with
laser based equipment, circuits, and networks.
•Never examine or stare into an open or broken optical fiber when it is connected to any laser
output device or equipment—whether or not that laser is activated.
•Always assume that the laser is on whenever it is not connected to a circuit or covered.
•Always deactivate the laser before connecting or disconnecting optical cables.
•When connecting or disconnecting the optical cables between this equipment and the circuit,
network, or equipment-under-test, use the following connection sequences.
•Connecting: Before activating the laser output (1) connect all optical cables to the
equipment-under-test, circuit, network, and this equipment (2) ensure that the circuit is
complete and properly terminated.
•Disconnecting: Before disconnecting any part or piece of the network, circuit, or
equipment-under-test (1) ensure that the laser is deactivated as detailed above.
