Description
The system 8000 fiber-optic interfacility links repre-
sent a comprehensive and simplified approach to
satellite earth station signal management and con-
trol. Essentially, the system is designed to bring
microwave technology into the 21^st Century by con-
verting microwave signals into continuously variable
amplitude-modulated optical signals.
Consisting of a high-performance, highly flexible fam-
ily of fiber-optic transmitter and receiver plug-ins,
system 8000 allows both microwave and RF signals
to be transmitted over long distances through fiber-
optic cable, and thereby eliminates the need for
coaxial and waveguide interconnections. A fiber-
optic link between the control room and antenna site
allows for convenient remote monitoring and control
as well.
The system can be tailored for a wide range of trans-
mit/receive frequency bands and offers an extensive
selection of unique, site-specific interconnectivity
solutions for satellite earth stations, including:
n Configurable 19 in. x 3u (5.25 in.) equipment chas-
sis that includes redundant power supplies; redun-
dancy switching options: single thread, 1:1, and
1:2; and selectable serial interfaces, RS-232 or
RS-485.
n Economical 70 MHz/140 MHz links for uplink
antenna remoting, downconverter output distribu-
tion, and intersite connections for backup or
antenna diversity.
n L-band links cover the 950 MHz—2050 MHz and
can be used for block downconverted C-, extended
C-, X-, or Ku-band signals, or for L-band Inmarsat
transmit and receive applications.
n C-, extended C-, X-, and Ku-band uplink and
downlink systems carry the main transmit and
receive signals between the control room and the
antenna site.
