OI1125 E/O Transmitter Instruction Manual
Installation
To properly install and power on the OI1125 E/O Transmitter, read this
procedure first to acquaint yourself with the instrument before performing the
procedure.
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 wavelength output from the OI1125 internal
laser is in the infrared band and is invisible to the human eye.
1. Be sure the operating environment is within the specifications listed in
Table 7 starting on page 21.
CAUTION. To prevent damage to the transmitter, provide proper ventilation. Do
not block the cabinet ventilation holes. Do not remove the cabinet feet; the feet
provide proper clearance for ventilation.
2. Leave space for cooling. Do this by verifying that the ventilation holes on
the sides, top, and bottom of the cabinet are free of any airflow obstructions.
Leave at least 5.1 cm (2 inches) free on each side.
3. Check that you have the proper electrical connections. The OI1125 E/O
Transmitter requires 100 to 240 VAC
RMS

10%, 47 Hz to 63 Hz,
≤
40 W.
4. Connect the proper power cord from the rear-panel power connector (see
Figure 7 on page 14) to the power system.
NOTE
. For the internal laser to function, either the laser safety interlock or an
external control circuit must be connected to the remote connector on the rear
panel. See Using the Rear-Panel Remote Interface on page 15.
5. If you intend to use the internal laser as the optical source for the transmitter,
connect the laser safety interlock to the remote connector on the rear panel,
or connect your external control circuit to the connector.
NOTE
. You need to make optical connections in the next step. Before making any
optical connection, clean your optical cables using the procedure on page 62.
6. If you are using the internal laser as the optical source for the transmitter,
connect the optical cable with FC/APC-PM connectors on both ends
(standard accessory, Tektronix part number 174-4664-00), between the
internal laser output and the modulator optical input. See Figure 1 on
page 1.
