Ominstar® GX2 GX2-LM1000B Series
Broadcast Transmitter 1310 nm
The OmniStar GX2-LM1000B Broadcast Transmitter utilizes a high-power DFB laser, an integrated low-noise
preamp, state-of-the-art predistortion and anticlipping circuitry. The compact, energy-efficient design allows up to
16 plug-n-play transmitter modules to operate in the four rack-unit OmniStar GX2 housing, minimizing valuable
headend space requirements. As the first gigahertz 1310 nm broadcast transmitter in the industry, it enables
operators to offer more revenue-generating services. Enhanced with PowerPC technology by Motorola, the
LM1000B series of transmitters introduces a new found intelligence to traditional headend equipment. The
hotswappable modules with unique embedded features like Quick-Swap Module Configuration maximize in-
service time by eliminating the need for manual configuration. The wide range of optical output power, coupled
with the full complement of other OmniStar GX2 application modules, provides
extreme flexibility for network design and fiber link optimization.TAR® GX2
