Olson Technology OTOHP-RRX - Manual (Page 3)

INTRODUCTION
The Olson Technology, Inc. Model OTOHP-RRX is a quad return path receiver module
optimized for good performance over a wide range of optical levels. This low-noise
receiver converts upstream optical signals into RF signals at the headend or remote
hubs. Internal selectable RF attenuators can be switched in or out to enable each
receiver to handle a very wide range of optical input signals. The module features four
completely independent receivers with four RF output ports, which are located on the
rear panel. The OTOHP-RRX provides +45dBmV output level. 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.
