Applications
Consisting of a high-performance, highly flexible family of fiber-optic transmitter and receiver plug-ins,
system 8000 allows both microwave and RF signals
to be transmitted over long distances through fiberoptic cable, and thereby eliminates the need for
coaxial and waveguide interconnections. A fiberoptic 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 transmit/receive frequency bands and offers an extensive
selection of unique, site-specific interconnectivity
solutions for satellite earth stations, including:
n
n
C-, extended C-, X-, and Ku-band earth stations
n
IF and L-band IFLs
n

Description
The system 8000 fiber-optic interfacility links represent a comprehensive and simplified approach to
satellite earth station signal management and control. Essentially, the system is designed to bring
microwave technology into the 21st Century by converting microwave signals into continuously variable
amplitude-modulated optical signals.
n
n
Configurable 19 in. x 3u (5.25 in.) equipment chassis that includes redundant power supplies; redundancy switching options: single thread, 1:1, and
1:2; and selectable serial interfaces, RS-232 or
RS-485.
Economical 70 MHz/140 MHz links for uplink
antenna remoting, downconverter output distribution, and intersite connections for backup or
antenna diversity.
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.
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.

uplink signal at the uplink EIRP monitor coupler
located at the antenna’s input feed flange.

March 6, 2003
Status information, including alarms and warnings, is
indicated by front panel LEDs and through standard
system monitor and control serial data ports on the
chassis rear panel.
Monitor and control data link provides a full-duplex,
fiber-optic path for either RS-232C or RS-422 data
for the earth station’s monitor and control system.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute 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.

Typical Block Diagram
As indicated in the block diagram below, the input and output amplifiers are integral to the system 8000. The tables
presented throughout the following sections, however, give the expected performance of each functional block in
the link with respect to their corresponding performance bands, including 70 MHz—140 MHz, L-band, and C-, X-,
and Ku-band interfacility links. These specifications, along with those for remote RF signal monitor interfacility links
and fiber-optic data links, are presented to aid in generating level diagrams for overall system analysis.

70 MHz/140 MHz Interfacility Link Specification
These links are designed to interconnect the up- and downconverters with the satellite modems or video exciters
and demodulators. They are specified to meet and exceed Intelsat requirements to 70 km. They are ideal for interconnections on site, to and from a diverse antenna site and for local access between a teleport and the end user.
The 70 MHz/140 MHz links are available as nonredundant or 1:1 redundant links only.

L-Band Interfacility Link Specifications
The L-band links can carry a downconverted C-, X-, or Ku-band polarization. They can also carry the L-band transmit or receive signals for a satellite mobile communications feederlink station for systems such as Inmarsat. Each
link is designed to meet and exceed all of the requirements for use in Intelsat Standard A and C earth stations even
under the highest signal-loading conditions. The links are especially useful for routing signals to and from a diverse
antenna site. One fiber is used in single-strand links and two are used in 1:1 redundant paths. Optionally, the path
may share a fiber-optic link with another path in 1:2 redundant configurations.

System 8000 Fiber-Optic Interfacility Links

Remote RF Signal Monitor Interfacility Link Specifications
These links bring the uplink RF test ports located at the antenna site back to the equipment room or control room.
This permits the operator to monitor the composite transmitted RF signals conveniently, quickly, and reliably without having to go to the antenna site or invest in a spectrum analyzer for every antenna site. In applications where
the system 8000 is being used for the main signal paths, these links can be included as plug-ins in the main chassis. Or, the uplink RF monitor links can be added to an existing earth station with all the output ports in one chassis
in the control room.

Fiber-Optic Data Link Specifications
These plug-ins can be added to the System 8000 chassis to provide a full duplex data path connecting the M and
C computer terminals at the antenna site and the equipment room. The standard version is for RS-422 serial data
with an option for RS-232. This link provides a data path only; there is no hand shaking, so a modem must be used
at each computer.

System 8000 Fiber-Optic Interfacility Links
System 8000 Redundancy
the backup link. If the fiber-optic cable containing the
fiber for the primary link is broken, the fiber-optic
receiver detects loss of received optical power and the
output is switched to the other channel. The switching
due to receiver failure works independently of the
external monitoring and control (M and C) system only
for the 1:1 configuration. For the 1:2 version, the external M and C must switch the input to the backup transmitter.
System 8000 provides multiple redundancy options.
The standard offerings are single thread, 1:1, and 1:2.
The 1:1 and 1:2 configurations offer two modes of
redundancy switching: automatic and manual.
Automatic Mode
In this mode, internal sensing and control provides
automatic switching to the backup link in case of any
failure in the optical system. If the laser temperature
alarm or laser optical power alarm is detected at the
fiber-optic transmitter, the faulty transmitter is shut off.
In the 1:2 redundancy scheme, if these conditions are
detected, the switch position is changed to select the
backup link. The fiber-optic receiver then detects loss
of received optical power and the output is switched to
Manual Mode
When this mode is selected, automatic switching to the
backup link is turned off. This mode can be selected
remotely through the M and C system or it can be
selected locally by pressing the auto-off button on the
front panel of the status and control plug-in on the
chassis.
