SAFETY WARNINGS

LASER RADIATION

The OLRT laser transmitter emits invisible radiation that can cause permanent eye
damage. AVOID DIRECT EXPOSURE TO BEAM. Operate the transmitter only with the
proper optical fiber installed in the transmitter optical connector. Power to the OLRT
transmitter should be turned-off or preferably, disconnected whenever the optical
connector cover is opened and there is no installed fiber (as when the fiber connector is
being installed or removed from the transmitter connector).

NEVER USE ANY OPTICAL INSTRUMENT TO VIEW THE OUTPUT OF THE
LASER TRANSMITTER. “OPTICAL INSTRUMENT” INCLUDES MAGNIFYING
GLASSES, ETC.

NEVER LOOK INTO THE OUTPUT OF THE LASER TRANSMITTER
NEVER LOOK INTO THE OUTPUT OF A FIBER CONNECTED TO A LASER

TRANSMITTER.
NEVER LOOK INTO OR USE ANY OPTICAL INSTRUMENT TO VIEW THE

DISTANT END OF A FIBER THAT MAY BE CONNECTED DIRECTLY OR VIA AN
OPTICAL SPLIT, TO A TRANSMITTER THAT MAY BE OPERATING. THIS
SPECIFICALLY APPLIES TO FIBERS THAT ARE TO BE CONNECTED TO
RECEIVERS (SUCH AS THE OLRR RECEIVER) OR OTHER DEVICES AT ANY
DISTANCE FROM THE LASER TRANSMITTER.

SHOCK HAZARD

The OLRT/OLRR is designed for indoor use only. Direct exposure to moisture must be
avoided.

GENERAL FEATURES

The OLRT L-Band fiber optic transmitter and the OLRR L-Band fiber optic receiver form
the basic L-Band Fiber Distribution System. The wide bandwidth 500MHz to 3,000MHz
or 10MHz to 3,600MHz 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 3.6GHz 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 single-mode 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.
