OmniStar ® GX2

Headend Optics Platform

GX2‐RX1000B

Forward Path Receiver

FEATURES

• Integrated low‐noise preamp and high‐performance post amplifier allows a high RF output level and exceptional distortion performance

• Up to 16 receiver modules in a four rack‐unit housing provide high module density

• Quick‐Swap Capability allows for replacement modules to be recognized and updated with previously stored settings

• Wide input range from –9 to +3 dBm with variable gain and slope controls to accommodate various system architectures

PRODUCT OVERVIEW

The Omnistar® GX2 forward path receiver is designed for headend and hub applications using standard Hybrid Fiber Coax Cable

Television wavelengths. The receiver features gain and slope controls to easily accommodate varying link budgets and support headend splitting and cabling requirements. The hot‐swappable modules, which feature unique embedded features like Quick‐Swap

Module Configuration, maximize in‐service time by eliminating the need for manual configuration. The adjustable features and high

RF gain of these receivers, coupled with the full complement of other OmniStar GX2 application modules, provide extreme flexibility for network design and fiber link optimization.

OmniStar® GX2‐RX1000B

The GX2‐RX1000B occupies one slot in the GX2‐HSG universal shelf. The standard SC/APC optical input connector is located on the front of the module for easy cleaning and installation. The dual fans on each module are field‐replaceable, and the fan current is monitored to provide operational status.

Operators can manually adjust the receiver’s RF gain and slope. Gain control allows operators to adjust the RF output level for customized C/N and distortion performance based on channel loading and system requirements. The slope control is designed to compensate for the forward link slope and cable length that might follow the GX2‐RX1000B within the headend or hub area. The

0 to +3 dB slope control range can compensate for up to approximately 50 feet of RG59 headend coaxial cable.

Module Features

The receiver’s front panel RF test point directly monitors the RF output and allows operators to conveniently setup and maintain the receiver. A blind mate RF output connector on the rear of the module allows operators to hot‐swap modules without disconnecting cables from the back panel of the housing. To provide path and equipment redundancy, the GX2‐RX1000B is designed to interface with both the OmniStar® GX2 RF Switch and the Optical Switch. Firmware is downloadable, and operators can upgrade firmware while the module remains in operation. No hardware changes are needed.

Communications

The GX2‐RX1000B supports several communication methods for real‐time system monitoring and control. A tri‐colored LED on each module indicates general operating status. The optional shelf door unit with display provides monitoring and control with an alphanumeric display and simple push button navigation. Finally, a PC interface is available through an Ethernet port on the front of the control module. Using a standard Web browser, the graphical user interface provides a point‐and‐click method of monitoring and controlling the shelf. For higher‐level management, the OmniStar GX2 can be easily connected to a remote network management system using the standard Ethernet SNMP interface.
