Operating Basics
This section describes the connectors and controls on the front and rear panels of
the OI1125. Figure 5 on page 11 and Figure 7 on page 14 illustrate the front and
rear panels of the instrument.
Handling
Handle the OI1125 E/O Transmitter carefully at all times. The instrument
contains sensitive optical and electrical components that can be damaged by
physical shocks.
WARNING.
To prevent eye injury, do not look directly into any optical output port
or cable attached to the port. Output power from the laser is Class IIIb, which
can be harmful to your eyes. The output wavelength from the OI1125 internal
laser is in the infrared band and is invisible to the human eye.
Connecting Signals
The OI1125 E/O Transmitter has two types of connectors for inputs and outputs.
The OI1125 E/O Transmitter electrical input uses a high-performance SMA
connector. Never attach a cable that has a worn or damaged connector because
this may damage the OI1125 connector.
Use extra care when attaching or removing a cable from the connectors. Turn
only the nut, not the cable. Use light finger pressure to make this initial
connection. Then tighten the nut lightly with a wrench.
For best repeatability and to prolong the life of both the cable and instrument
connectors, use a torque wrench and tighten the connection to the range of 79 to
112 N-cm (7 to 10 lb-in).
If the connectors will receive heavy use, such as in a production environment,
you should install connector-saver adapters on the OI1125 E/O Transmitter to
make connections to the device under test.
The output of the OI1125 E/O Transmitter can couple to optical fibers with a
core diameter of up to 9
m
m. Alternative optical connector types can be coupled
by using the optional FC, ST, SC or DIN adapters. (Refer to Optional Accesso-
ries on page 3.)
