INTRODUCTION
The Olson Technology OTPT-300 is a cost effective field installable return laser transmitter with an RF
passband of 5 to 70 MHz. The unit has a DFB laser with 3mW output (+4.8dBm) or a FP laser with 1.6mW
output (2.0dBm). This transmitter is intended only for indoor applications. This transmitter must be mounted to an
OTPN-1000 Piconode. It will not function as a standalone device. The diplex filter, test point, return OMI pad,
and AC power supply are part of the OTPN-1000. The actual return passband is determined by the diplex filter in
the OTPN-1000.
ENVIRONMENTAL CONSIDERATIONS
The OTPT-300 is specified to operate from -10°C to +55°C. It will probably not require an air-
conditioned environment. It should be mounted in an adequately ventilated area. Like any other electronic
equipment, it will probably have a longer life span if it is not operated at the upper limit of the temperature range.
Installation in wet areas or areas of extremely high humidity should be avoided. Extremely dirty or dusty areas
should be avoided if possible. Objects or debris should not be allowed to block the openings in the OTPN-1000
housing or fan. The unit should not be installed in areas that are accessible to children.
OPTICAL CONNECTORS AND CLEANING
The standard optical connector is an SC/APC. In order to use FC/APC connectors, you must order a
conversion kit, OTLL-SCFCKIT. The standard optical connector location is on the opposite side from the RF
connector. The connector can be moved to the other side by swapping it with a cover plate. Only a screwdriver is
required for either operation.
Either of these operations must be done before the OTPT-300 is mounted to the OTPN-1000. Failure to
replace all of the OTPT-300 cover screws can cause RF ingress problems.
The fiber ends can be damaged by the insertion of contaminated connectors. Some types of customer
damage to connectors are not covered under warranty. Fiber connectors should never be left uncovered.
Prepackaged alcohol wipes are the most convenient means of cleaning optical connectors. Clean alcohol and lint
free wipes or swabs may also be used.
