SAFETY WARNINGS

LASER RADIATION

The OTOHP-FTX laser transmitter emits invisible radiation that can cause permanent eye
damage. . Operate the transmitter only with the proper

AVOID DIRECT EXPOSURE TO BEAM

optical fiber installed in the transmitter optical connector.Powertothetransmittershouldbeturned­off 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. “OPTICALINSTRUMENT”INCLUDESMAGNIFYINGGLASSES,ETC.

NEVER

LOOK INTO THE OUTPUT OF THE LASER TRANSMITTER

NEVER

LOOK INTO THE OUTPUT OF A FIBER CONNECTED TOA LASER

TRANSMITTER.

NEVER

LOOK INTO OR USE ANY OPTICAL INSTRUMENT TO VIEW THE DISTANT END
OF A FIBER THAT MAY BE CONNECTED DIRECTLY OR VIAAN OPTICAL SPLIT, TO A
TRANSMITTER THAT MAY BE OPERATING. THIS SPECIFICALLYAPPLIES TO FIBERS
THATARE TO BE CONNECTED TO RECEIVERS OR OTHER DEVICES ATANY
DISTANCE FROM THE LASER TRANSMITTER.

PRECAUTIONS

Failure to comply with these general safety precautions and with the specific precautions
described elsewhere inthis manualviolates the safety standards of the design, manufacture, and
intended useof thedevice. Olson Technology Inc. assumesno liability forthe customer's failureto
comply with these precautions.

Do not operate the transmitter outside of its ratings. Doing so may result in unsatisfactory
performance, receiver failure, shortened receiver life span, or a safety hazard.

Do not attempt to modify or service any part of a transmitter module. Doing so voids the warranty.
Contact Olson andrequest an RMAnumberandreturntheunitto OlsonTechnology Inc.for service
and repair.

Do not restrict airflow in front of or behind the chassis. The transmitter should be operated in an
ambient environment between 0 and 50ºC (32 and 122ºF).

Store the module awayfrom corrosivematerials,ata temperature between -40 and +70ºC (-40 and
+158ºF), and with no more than 85% humidity,non-condensing.

INTRODUCTION

The OTOHP-FTX series is a high performance 1310nm DFB laser transmitter module
that is ideal for broadcast and narrowcast applications in optical transportation. The
modules are available over wide range of optical output power to deliver both analog
and (QAM) CATV digital signals. High performance, advanced pre-distortion circuitry
achieves superior CSO and CTB. All configuration parameters of modules can be
monitored by LED screens on the front panel of the module, or by the OTOHP-NMS
equipment management module. The OTOHP-FTX module can be operated also by
Automatic Gain Control (AGC) or Manual Gain Control (MGC) modes. These modes
can be set uponthefront panel.
