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 OPTICAL 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

ALWAYS connect a fiber to the output of the device BEFORE power is applied. Power should never be applied

without an attached fiber output. If the device has a connector output, a connector should be attached 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 (1310nm

and 1550nm) are totally invisible to the unaided eye and will cause permanent damage. Shorter wavelengths lasers
(e.g. 780nm) are visible and are very damaging. Always use instruments, such as an optical power meter to verify light
output.

BEFORE applying power.

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 INC. (OTI) before

powering your product.

GENERAL FEATURES

The OTLT linear fiber optic transmitter and the OTLR linear fiber optic receiver form the basic L-Band Fiber Distribu­tion System. The wide bandwidth of 500MHz to 3,000MHz 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 3.0GHz allows this to accommodate additional transponders including Euro­pean satellite communications applications. The enhanced bandwidth also facilitates stacked LNB applications to
accommodate additional transponders containing enhanced DBS services (HDTV, local channels, etc.) over single­mode fiber for DBS distribution.

These stand-alone versions are designed for mounting in outdoor enclosures or in other small spaces. For powering,
the stand-alone units both the transmitter and receiver can be powered via the wire leads or on the center of the coax
connector.

RF PERFORMANCE

The specifications are cited below with 12dB link optical loss and >55dB optical return loss. RF input level to Tx
@12dBmV, the level to the high gain Rx is -9dBm Optical Power unless otherwise specified.

RF Frequency Range 500-3,000MHz
Amplitude Flatness ±1.5dB for any 500MHz, ± 0.35dB for any 40 MHz
Return Loss 10 dB
I/O Connector F-Type Female (75 Ohms) Standard)
Link Gain @ 25°C -4 ± 5 dB
Noise Figure with -9dBm Optical Pwr to Rx 45dB MAX, typically better than 32dB
CNR @ 12dBmV IN, 27MHz BW Better than 17.7dB
Input 1 dB Compression to -20°C >-17dBm, see chart next page for typical performance
Input IP3 to -20°C -9.5dBm
Gain vs. Temperature Tx= 0.12dB/°C Rx= 0.09dB/°C
Max. Total RF Power in -14dBm
