SAFETY WARNINGS

LASER RADIATION

The OTPT-300 laser transmitteremits invisible radiation thatcancause permanent eye
damage. . Operate the transmitter onlywiththe
proper optical fiber installed in the transmitter optical connector. Power to the OTPN­2000C should beturned-off orpreferably, disconnected whenever the optical connector
cover is opened and there is no installed fiber (as when the fiber connector is being
installed or removed fromthetransmitterconnector).

The power supply section (bottom section) of the OTPN-2000C contains no user
serviceable parts. There is exposed high voltage inside this section. Only factory
service technicians should openthepowersupplysection.

The AC line input fuse is containedin the IEC 320 power input connector. This fuse is a
3AG, 0.5A, slow blowfuse. To avoid a risk of fire, this fuse shouldbe replaced only with
an identically rated fuse.

The OTPN-2000Cis designed forindoor use only. Direct exposureto moisture mustbe
avoided.

AVOID DIRECTEXPOSURETO BEAM

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 OTPN-2000C) OR OTHER DEVICES AT ANY
DISTANCEFROMTHE LASERTRANSMITTER.

INTRODUCTION

The Olson Technology Inc. OTPN-2000C is ahigh-quality, cost-effective, bi-directional
CATVnode designed withthe latest opticalreceiver technology. It operates withoptical
input levels ranging from -6dBm to +2dBm. Thereceive RF pathinclude a plug-in 15dB
equalizer to provide for sloped output response as well as plug-in pads to set the
forward and reverse RF gains. The OTPN-2000C is available with two different band
splits.

OTPN-2000C 5-42MHz Reverse Band, 54-1,000MHzForwardBand
OTPN-2000C-PAL 5-65MHz Reverse Band, 85-1,000MHzForwardBand

The OTPN-2000C does not come with a reverse transmitter. The OTPT-300 return
transmitter is field-installed in the OTPN-2000C node. The OTPN-2000C has a
universal power supply that allows operation from 90-240 V @50 or 6 Hz. It consumes
less than 23 Watts of power . Positive cooling is

including an OTPT-300 Transmitter

AC

provided by means of a small, high-MTBF fan, which may be replaced in the field
without interrupting operation. The OTPN-2000C has flanges on the bottom to allow
mounting it to a flat surface. The available OTLL-RMKIT-2 will allow mounting up to
three of these nodesinastandard19"rack.

INSTALLATION/ENVIRONMENTALCONSIDERATIONS

The OTPN-2000C operates from -10°C to +55°C. An air-conditioned environment is
usually not required. Mount in an adequately ventilated area. Like all electronic
equipment, it will have a longer life span if it is not operated at higher temperatures. Do
not install in wet areas or areas of extremely high humidity. Avoid extremely dirty or
dusty areas. Do not block the openings in the housing or the fan. Do not install the
OTPN-2000C in areas that are accessible to children. The OTPN-2000C may be
installed and operated in any position on a flat surface. The unit has four slots in the
bottom plate to accommodate mounting hardware. Mount with a #6 or #8 pan-head
sheet metal screw,ora6-32pan-headmachinescrew. See Figure 1 for dimensions and
mounting details. This is due to limited clearance under the OTPT-300 that is above
some of the mounting slots. If the OTPN-2000C has an installed OTPT-300, mounting
or dismounting the unit does not require the disconnection of the OTPT-300. The fiber
connector can be moved to the other end of the unit. Make forward and reverse RF
adjustments to the OTPN-2000Cbeforemountinginarack mountkit.
