RECEIVER DESCRIPTION
The OLAR L-Band Receiver can handle 10MHz to 4,000MHz RF signals. The receiver includes
a 25dB digital gain control. Optical input power ranges from -15 to +3dBm in the wavelength
range of 1270-1610nm. The receiver offers high sensitivity for an expanded optical link budget
from -22dBm to -3dBm. Built-in test points, LED indicators and alarms allow the receiver to
be easily set up and maintained.

RECEIVER CONTROLS OVERVIEW
Figure 3 shows the front and rear panels of the receiver.
On the front of the transmitter, the user can change the gain of the transmitter over a 25dB
range using S1 & S2. Higher gain allows the transmitter to be used with lower level RF sig-
nals and vice versa. S1 is a 16-position, hexadecimal, rotary switch. The “0” setting is mini-
mum gain and the “F” setting is the maximum gain. Each position is equal to a 1dB gain
change. So the gain of the “F” setting compared to the gain of the “0” setting will be 15dB
higher. The bottom switch of S2 is a high/low gain setting. When it is in the “Lo” position, the
incremental gain is 0dB. When it is “Hi” position, the gain increases by 10dB. To set the
