Motorola’s OmniStar GX2-LM1000E Series 1310 nm Broadcast Transmitter uses a high-power DFB laser, an integrated low-noise preamp, and state-of-the-art predistortion and anticlipping circuitry for superior performance. The compact, energy-efficient design allows up to 16 plug-and-play transmitter modules to operate in the 4 RU OmniStar GX2 housing, maximizing valuable headend space. Enhanced with PowerPC technology, LM1000E series transmitters introduce intelligence to traditional headend equipment. Hot-swappable modules with Quick-Swap Module Configuration maximize in-service time by eliminating the need for manual configuration. The wide range of optical output power is coupled with the full complement of other OmniStar GX2 application modules, providing extreme flexibility for network design and fiber link optimization.

OmniStar GX2 is a fiber optic broadband transmission platform designed for the Broadband Hybrid Fiber/Coax Networks of tomorrow.

The OmniStar GX2 provides increased module density, while continuing the OmniStar legacy of scalability, performance, and flexibility. The four rack-unit chassis accepts up to 16 Plug-n-Play application modules, minimizing headend space requirements. A two rack-unit mini-chassis is also available that holds three application modules. With superior 1310 nm and 1550 nm products, the OmniStar GX2 enables you to offer more revenue-generating services. The universal platform and full complement of application modules can accommodate any system architecture. Enhanced with PowerPC® technology provided by Motorola, this next generation broadband platform brings newfound intelligence to traditional headend equipment. The high-performance chip, used in today’s luxury automobiles to enable in-car networking, is the foundation of this denser, smarter, and moreefficient design.

The OmniStar® GX2-EM870 series of 1550 nm Broadcast Transmitters uses advanced optical linearization technology to provide low noise and superior distortion performance. The suite of products satisfies various applications: full band loading or split band loading, super-trunking or distribution to nodes, long-distance transport or short hops. Several different versions of the transmitter are available that are optimized for transmission system standards with 6 MHz, 7 MHz, and 8 MHz video channels.
A proprietary technique provides Stimulated Brillouin Scattering (SBS) suppression up to 16 dBm to enable long links when used in conjunction with optical amplifiers. The transmitter uses a 1550 nm DFB laser diode as a precision light source, which is modulated by an optically linearized Mach-Zehnder modulator. Use of external modulation technology eliminates laser chirp and allows designs of transport systems for distances well beyond 100 kilometers.
Enhanced with PowerPC® technology, the GX2-EM870 series introduces a new found intelligence to traditional headend equipment. The system performance is continuously monitored and a sophisticated control algorithm assures optimum performance.

Motorola's OmniStar GX2-OA100B Series erbium-doped optical amplifiers serve multiple applications for HFC networks including super-trunking, direct distribution to many nodes, and DWDM narrowcast and return. The GX2-OA100B Series optical amplifiers are designed for use with the OmniStar® GX2 1550 nm broadcast transmitters and DWDM transmitters. With adjustable output and several nominal output powers available, the GX2-OA100B Series accommodates a wide range of link budgets. Its three operating
modes can satisfy a wide range of system design requirements: Constant Output Power mode to maintain exact optical levels; Constant Pump Power mode to optimize noise figures; and Constant Gain mode for DWDM applications. The GX2-OA100B Series Optical Amplifiers employ a proprietary erbium-doped fiber formulation that provides low noise performance, along with the most reliable 980 nm pump lasers available in the industry.
Other user benefits offered as part of the OmniStar GX2 platform include: higher density, SNMP interface for network management, and Quick-Swap module capability.

With two independent receivers in the module, the OmniStar GX2-RX200BX2 return path receiver module provides a high-density solution for advanced upstream video and data traffic. The wide optical input power range can accommodate today’s evolving networks with varying link budgets. An integrated low-noise pre-amplifier and high-performance post-amplifier offers high RF output level and exceptional distortion performance.
Enhanced with PowerPC technology by Motorola, these receivers introduce a new found intelligence to traditional headend equipment. The hot-swappable modules with unique embedded features, like Quick-Swap Module Configuration, maximize in-service time by eliminating the need for manual configuration. This receiver, coupled with the full complement of other OmniStar GX2 application modules, provides extreme flexibility for network design and fiber link optimization.

The GX2-PSAC and GX2-PSDC modules are installed in the rear of the Omnistar GX2 Housing (GX2-HSG) where power connections are easily made. Integrated fans provide localized cooling. A tri-colored LED on the rear of the unit indicates operating status. An additional tri-colored status LED is provided for each power supply on the front of the Control Module (GX2-CM100B). Though on ower supply can power an entire housing, the GX2-HSG accommodates two power supplies for true power source redundancy. When two power supplies are used, the load is shared between both supplies. If one supply fails, the other immediately picks up the additional load. For increased flexibility, the second power supply can be either AC or DC depending on system needs.

The GX2-CM100B control module supervises all the application modules and power supplies within the housing while also serving as the communication gateway between the modules and the various user interfaces. Three tri-colored LEDs are located on the front panel of the module: one indicates the worst-case status for all application modules and the other two indicate the status of the power supplies. The front panel Ethernet port allows local control and monitoring of all modules through a Web browser-style interface on a PC. The rear Ethernet port can be used for SNMP communications with a network management system.
Although the application modules can operate without it, the control module is necessary to setup and monitor modules through either the display option on the shelf door or the Web browser-style interface. The control module also enables some of the advanced OmniStar GX2 features such as Quick-Swap Module Configuration and downloadable firmware.
