Product Description

FOXCOM AL5T2 CATV/SMATV chassis mount transmitters process AM/VSB, 8VSB, QAM or terrestrial signals inputs
from multiple current or planned sources. Using direct modulation, signal integrity is preserved, guaranteeing excellent
video quality required for High Definition reception. The AL5T2 Series serves a full range of high performance CATV/SMATV
applications cost effectively. A variety of lasers, output powers, wavelengths and options are available to
maximum flexibility and scalability.

When coupled with Foxcom’s FPS line of LGX style optical passive components, transmitter outputs may be split or
multiple AL5T2 signal paths can be combined using Wave Division Multiplexing to make use of existing fiber
infrastructure and ensure future expansion capability.

The AL5T2 CATV/SMATV transmitter module occupies two slots on the AL-500 19” 3U active shelf.
