Olson Technology OTOHP-RFG - Manual (Page 3)

INTRODUCTION
The Olson Technology, Inc. Model OTOHP-RFG is a quad return path receiver module
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
features four independent receivers with four RF output ports located on the rear panel
of the receiver module. The OTOHP-RFG typically provides a minimum +30dBmV RF
output level over the full -13dBm to -27dBm optical input range. The front panel controls
allow local management and monitoring of the module while the RS-485 interface and
the OTOHP-NMS network management module allow remote management and
monitoring of the module.
