Description
The System 10000 TVRO L-band and C-band fiber-
optic links provide a simple and extremely reliable
connection between a receive-only earth station
antenna site and the associated satellite receivers at
a remote location using standard single-mode optical
fiber. They are primarily used in cable television hea-
dends and broadcast television facilities. Standard
versions allow for cable lengths of up to 15 km, while
the high-performance models can be used at up to
40 km distance.
For each LNA or LNB output, the entire polarization
is converted to an optical signal by direct modulation
of a semiconductor laser diode, and is then con-
verted back to an RF signal by a PIN photodiode at
the other end of the fiber. The link is format-indepen-
dent due to its inherently low phase noise, so it may
be used with either FM or QPSK modulated signals.
Fiber-optic cable is compact, flexible, and light-
weight, and provides electrical isolation and immunity
from electromagnetic interference.
The System 10000 product family includes a com-
plete selection of fiber-optic transmitters, receivers,
input and output gain controls, and ac power supplies
in 3U high, rack-mount plug-ins. Both L-band and
C-band versions are available and may be used in a
unique L-/C-band configuration that carries two
polarizations on one fiber. Input gain controls offset
conversion and optical losses to ensure adequate
signal at the satellite receiver. Each 19 in. wide rack
chassis has the capacity for up to four polarizations
plus two redundant power supplies, and all plug-ins
are hot swappable.

Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
