SAFETY WARNINGS

LASER RADIATION

The optical fiber connector attached to the OTOHP-RFG quad RFoG receiver emits invisible
radiation that can cause permanent eye damage. .
Operate the receiver only with the proper optical fiber installed in the receiver optical connector.
Power to the receiver 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
installedorremovedfromthetransmitterconnector).

PRECAUTIONS

Failure to comply with these general safety precautions and with the specific precautions
described elsewhere inthis manualviolates thesafety standardsof thedesign, manufacture, and
intended useof thedevice.OlsonTechnology Inc. assumesnoliability forthecustomer's failureto
complywiththeseprecautions.

Do not operate the receiver outside of its ratings. Doing so may result in unsatisfactory
performance,receiverfailure,shortenedreceiverlifespan,orasafetyhazard.

Do not attempt to modify or service any part of a receiver module. Doing so voids the warranty.
ReturntheunittoOlsonTechnology Inc.for serviceandrepair.

Do not restrict airflow in front of or behind the chassis. The receiver should be operated in an
ambientenvironmentbetween0and50ºC(32and122ºF).

INTRODUCTION

The OlsonTechnology, Inc.Model OTOHP-RFGis a quadreturn path receivermodule
optimized for good performance at the low optical levels associated with RFoG
systems. This low-noise receiver converts upstream optical signals into RF signals at
the headend or remote hubs. The OTOHP-RFG receiver is designed to operate with
Olson Technology’s OHP ( ptical eadend latform) series of products. The module

OH P
features fourindependent receivers with four RFoutput portslocated onthe rear panel
of the receiver module. The OTOHP-RFG typically provides a minimum+30dBmV RF
output leveloverthe full-13dBmto -27dBmoptical input range.Thefront panelcontrols
allow local management andmonitoring of the module while the RS-485 interface and
the OTOHP-NMS network management module allow remote management and
monitoringof the module.
