Omnistar GX2-RX1000B
Forward Path Receiver
The OmniStar GX2-RX1000B Forward Path Receiver offers a greater
operational bandwidth while continuing the OmniStar legacy of superior
reliability and performance.
The
The Omnistar GX2 forward path receiver is designed
for headend and hub applications using 1310 or
1550 nm wavelengths. Gain and slope controls are
provided to easilyaccommodate varying link budgets,
as well as headend splitting and cabling needs. The
GX2-RX1000B provides a high-density solution for
high bandwidth downstream optical transport. These
receivers introduce a new found intelligence into
traditional headend equipment. The hot-swappable
modules
modules with unique embedded features, like QuickSwap
Swap Module Configuration, maximizein-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

OmniStar GX2-RX1000B Forward Path Receiver

Product DescriptionThe GX2-RX1000B is a forward path optical receiver module for the OmniStar® GX2 optical broadband
transmission platform. It occupies one slot in the GX2-HSG universal shelf. The optical input connector is
located on the front of the module for easy cleaning and installation. The standard connector type is SC/APC.
An E2000 connector is also available. The dual fans on each module arefield-replaceable, and the fan current
is monitored to provide operational status.
Both RF gain and slope can be manually adjusted. Gain control allows the user 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 theGX2-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 front panel RF test point directly monitors the RF output and is convenient for setup and maintenance of
the receiver. A blind-mate RF output connector on the rear of the module allows modules to be hot-swapped
withoutdisconnecting 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 can be upgraded while the module remains in operation. No hardware changes
are needed.
Intelligence
Each OmniStar GX2 module utilizes a powerful microprocessor, which allowssophisticated control functions
along with high integration; this single-chip design contains flash memory, random access memory, and
analog/digital converters. Manufacturing test data and all specific module information (i.e., firmware, bitmaps,
menu structure, etc.) are stored in the non-volatile memory.
Communications
Several communication methods are available for real-time system...
