Over range LED/Signal LED
Two LEDs on the front of the OE-2 indicate optical input signal status. The lower “SIGNAL” LED is lit
when the OE-2 senses an optical signal. If the upper “OVERRANGE” LED is blinking red, the optical
signal power is beyond the input range of the instrument and should be removed to prevent damage to the
optical detector.
If both LEDs are blinking, the O/E receiver temperature stabilization is not within range. Measurements
made during this condition are not valid. If this occurs, turn off the unit for a few minutes and turn it back
on. It may be necessary to move the
OE-2 to a cooler location. If this condition persists, the unit should
be serviced by an authorized
WAVECREST service representative.

Channel 1 Optical Input
This FC/UPC input connector accepts either single-mode or multi-mode (up to 62.5 um) optical fibers.
Optical signals from 770 to 1650 nm can be used.
Before attaching any connector to the OE-2, clean all
optical connections using an optical
fiber connector cleaner such as the NTT-ME CLETOP.
CAUTION: Do not exceed +3 dbm peak optical power.
5
Channel 1 Electrical Output
The electrical output signal is available at this 50 Ohm SMA connector. The converted electrical signal is a
linear representation of the optical signal.
CAUTION: This output port is sensitive to electrostatic discharge. Use ESD protection when
connecting to this port.

Channel 2 Optical Input
This FC/UPC input connector accepts either single-mode or multimode (up to 62.5 um) optical fibers.
Optical signals from 770 to 1650 nm can be used.
Before attaching any connector to the OE-2, clean all optical connections using an optical
fiber connector cleaner such as the NTT-ME CLETOP.
CAUTION: Do not exceed +3dbm peak optical power.

Front Panel On/Off Switch
The front panel switch turns the internal power supply on or off.
9
Local/Remote Switch
The Local/Remote switch selects between local mode and remote GPIB operation. In local mode,
settings are selected using the Filter and Amplifier Selection knobs. In GPIB remote operation, settings
are selected by using OE-2-specific commands via the GPIB. The Local/Remote pushbutton is lit when
in local operation.
