Motorola OMNISTAR GX2-LM1000E Series User Manual

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 equip-
ment. 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.
