SAFETY
Safety Precautions
The optical emissions from the units are laser-based and may present eye hazards if improperly used. NEVER USE ANY KIND OF OPTICAL INSTRUMENT TO VIEW THE OP-
TICAL OUTPUT OF THE UNIT. Be careful when working with optical fibers. Fibers can
cause painful injury if they penetrate the skin.
Laser Safety Procedure
ALWAYS read the product data sheet and the laser safety label before powering the product.
Note the operation wavelength, optical output power and safety classifications.
If safety goggles or other eye protection are used, be certain that the protection is effective at
the wavelength emitted by the device under test BEFORE applying power.
ALWAYS connect a fiber to the output of the device BEFORE power is applied. Power must
never be applied without an attached fiber. If the device has a connector output, attach a
connector that is connected to a fiber. This will ensure that all light is confined within the fiber waveguide, virtually eliminating all potential hazard.
NEVER look at the end of the fiber to see if light is coming out. NEVER! Most fiber optic laser
wavelengths (1270nm through 1610nm) are totally invisible to the unaided eye and will cause
permanent damage. Shorter wavelengths lasers (e.g., 780 nm) may be visible and are very
damaging. Always use instruments, such as an optical power meter, to verify light output.
NEVER, NEVER, NEVER look into the end of a fiber on a powered device with ANY sort of
magnifying device. This includes microscopes, eye loupes and magnifying glasses. This WILL
cause a permanent and irreversible burn on your retina. Always double check that power is
disconnected before using such devices. If possible, completely disconnect the unit from any
power source.
If you have questions about laser safety procedures, please call Olson Technology before
powering your product.

GENERAL FEATURES
The OLAT Advanced L-Band Transmitters and the OLAR Advanced L-Band Receivers form a
feature-rich L-Band Fiber Optic Distribution System in a very compact package. The wide
bandwidth, from 10MHz to 4,000MHz, allows for a wide variety of communications applications including L-Band satellite antenna remoting, trunking radio, telemetry tracking and
time and frequency reference distribution. The extended frequency range to 4,000MHz and
digital gain adjustment range of 25dB in the transmitter and a digital gain adjustment range
of 25dB in the receiver allow these products to accommodate additional transponders including European and multiple satellite communications applications. The enhanced bandwidth
also facilitates stacked LNB applications to accommodate additional transponders containing
enhanced DBS services (off-air digital television signals) over single-mode fiber for DBS distribution.
RACKMOUNT CONFIGURATIONS
The transmitter, receiver and power supply are housed in rugged, compact, standalone enclosures. Rack mount configurations of the Advanced L-Band System offer an economical,
high-density solution. An adapter mounting plate refits the units on a 1RU or 2RU 19" plate
for installation in an EIA 19" rack. The 2RU plate will allow up to six units to be mounted in a
2RU space. No adapters are required; all units mount directly to a Model OTLL-RMKIT-4
adapter plate that can accommodate three transmitter/receiver modules in a 1RU space and
the Model OTLL-RMKIT-5 can accommodate six units in a 2RU space. The system includes a
tray area for fiber organization.

TRANSMITTER DESCRIPTION
The Advanced L-Band Transmitter carries 10MHz to 4,000MHz RF signals over single-mode
optical fiber. Model OLAT includes an adjustable 25dB digital gain control. Laser power options include +4dBm/2.5mW (DFB, CWDM), +5dBm/3mW (DFB) or +10dBm/10mW (DFB,
DWDM). The transmitter offers two LNB powering options. The LNB may be powered
through a standard “F” connector with a power supply or power inserter or via the
OTAPS-4000 power supply through a 9-pin DIN connector. The OTAPS-4000 has selector
switches allowing each transmitter to have its LNB voltage set at +13V or +17V and also to
turn a per-channel 22kHz tone on or off. The LNB Current is limited to about 0.5 Amps. Any
attempt to draw more than 0.5 Amps will cause the LNB voltage to be pulsed at a 0.1% duty
cycle until the current drops below 0.5 Amps. Built-in test points, LED indicators and alarms
allow the transmitter to be easily set up and maintained.
Figure 1 - Front & Rear View of Transmitter
TRANSMITTER CONTROLS OVERVIEW
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 signals and vice versa. S1 is a 16-position, hexadecimal, rotary switch. The “0” setting is minimum 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 left 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 transmitter for minimum gain, set S1 to “0” and the left switch of S2 up. To set the transmitter for
025-000570 Rev. X7 www.olsontech.com 5
maximum gain, set S1 to “F” and the left switch of S2 down.
The right switch of S2 allows the LNB power to be switched on or off. When the switch is in
the “Off” position, no LNB voltage will be applied to J4. When the switch is in the “On” position, LNB voltage from either J5 or J6 will be applied to J4. J1 & J3 allow easy measurement
of the transmitter optical output power using a D
igital Volt Meter (DVM). J1 is a ground. J3
gives an indication of the laser power. The scale factor is 0.1V/mW. J2 is the optical output.
D1 indicates that the Laser Power is OK. It will be green if the laser control circuitry is behaving normally. If the laser or control circuitry fails, then D1 will turn red.
D2 indicates the input RF Level. Figure 2 indicates the thresholds at which D2 will switch. D2
will be yellow if the RF level is below the low threshold, red if the RF level is above the high
threshold and green if the RF level is between the low and high thresholds. For most applications, if D2 is green, then the RF level is in the optimum range. J4 is the RF Input. It is a
high-frequency F-Type Female (75Ω) Connector.
Figure 2 - D2 Behavior
On the rear of the transmitter, connector J5 is used to connect to the OTAPS Advanced
L-Band Power Supply. When it is used, D3 and D4 give a local indication of the LNB voltage
and the 22kHz tones being generated in the OTAPS power supply. J6 and J7 are used when J5
is not used. J6 provides an alternate means of injecting an LNB voltage input via an “F” connector. Connector J7 allows the unit to be powered via an “F” connector. Allowable input
power voltage is +8V
to +24VDC. Connector J8 provides various status outputs. They will be
DC
described in more detail later in this document. See Figure 5.
Note: If J5 is not used with the OTAPS power supply, the D3 LED’s will still give some indication of the LNB voltage. They are designed to switch at +15 Volts. The LNB voltage will only
be applied to the J4 connector when the right switch of S2 on the front panel is in the up or
“On” position.

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 a maximum optical link budget.
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 signals and vice versa. S1 is a 16-position, hexadecimal, rotary switch. The “0” setting is minimum 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 left 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 transmitter for minimum gain, set S1 to “0” and the left switch of S2 up. To set the transmitter for
maximum gain, set S1 to “F” and the left switch of S2 down.
The right switch of S2 also allows the final RF amplifier to be switched on or off (Mute). When
the receiver output is Muted, the RF output level typically drops by 30dB. Note that the RF
025-000570 Rev. X7 www.olsontech.com 7
Level detector (discussed later) still functions as though the receiver is not muted.
J1 & J3 allow easy measurement of the transmitter optical output power using a Digital Volt
Meter (DVM). J1 is a ground. J3 gives an indication of the Optical Input Power. The scale
factor is 1.0V/mW. J2 is the optical input. D1 indicates the RF Output Power level. D2 indicates the input RF Level. Figure 2 indicates the thresholds at which D2 will switch. D2 will be
yellow if the RF level is below the low threshold, red if the RF level is above the high threshold
and green if the RF level is between the low and high thresholds. For most applications, if D2
is green, then the RF level is in the optimum range. Table 1 shows the behavior of the Receiver D2 LED. J4 is the RF Output. It is a high-frequency F-Type Female (75Ω) Connector.
Table 1 - Receiver D2 LED Behavior
RF Output Level D2 LED Color
<-37dBm Yellow
≥-37dBm and ≤ -22dBm Green
>-22dBm Red
Note: This holds true even if the Receiver output is Muted
On the rear of the transmitter, connector J5 is used to connect to the OTAPS Advanced
L-Band Power Supply. Connector J6 is for unit power voltage input via an “F” connector.
Connector J7 provides various status outputs. These will be discussed later in this document.
See Figure 6.

POWER SUPPLY CONTROLS OVERVIEW
On the front of the power supply, D1 indicates that the power supply is powered and operating
normally. D2 indicates if there is a fault with any of the units connected to the power supply.
LED’s D3 through D7 indicate if Units 1 through 5 are connected. Switches S1 through S5 are
used to select +13 Volts or +17 Volts for each unit and also turn on or off the 22kHz tone.
On the rear of the unit, connectors J1 through J5 are used to power up to five transmitters or
receivers. Connector J6 is the AC input. It also contains the AC fuses for the unit. See Figure 7
for details.
