Optical components
Which optical components for which application?
To enable the transmission of CATV signals over large distances, the application of optical
transmission technology is essential. While the signal gets corrupted after only a few kilome-
ters of transmission when using ordinary coax-cable connections, an optical transmission line
can bypass a much larger distance - with much lower impact on the signal quality. For optical
transmission purposes ASTRO offers a complete component system:
Optical Head-end platform
Optical Nodes
LWZ-series: Basic element of the optical
Head-end platform is the 19“ base unit LWZ B.
This module rack is designed for housing
different optional modules: optical transmitters
in 1310 nm and 1550 nm, quad return path
receiver, controller and power supplies. The
compact design of this technology allows
installation of up to 12 modules in only three
HU. The power supply is achieved by modular
built, hot-swappable power supply units.
LWO-series: ASTRO offers optical nodes at
different power ratings. The LWO 2xx are fully
integrated forward path receivers in compact
housing while the LWO 3xx are built modular
and can be matched to individual require-
ments in transmission networks. In this series
different return path transmitters are available
and the configuration of the RF output is higly
variable by the use of pluggable splitters and
taps.
Optical reception and distribution technology
ASTRO offers optical splitters in 19“ housing
for splitting optical CATV signals.
For optical SAT-IF splitting there are an optical
LNB, different splitters and opto-electrical
converters with Twin, Quad and Quatro-
universal outputs available.
As a supplement to this series and to satisfy special needs of customers ASTRO offers also
19“ Stand-alone solutions for optical transmission and reception technology.
