System 8000 Fiber-Optic Interfacility Links

Designed to interface directly with earth station equipment, the multifaceted System 8000 interfacility link offers a wide

variety of unique, site-specific interconnectivity solutions for satellite earth stations.

Consisting of a high-performance, highly flexible fam-

ily of fiber-optic transmitter and receiver plug-ins,

Features

system 8000 allows both microwave and RF signals

to be transmitted over long distances through fiber-

n EIRP monitoring capability

n RS-232 or RS-485 serial interface

n RS-232 or RS-422 data link

n RFI/EMI immunity

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 CE approved

Applications

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 C-, extended C-, X-, and Ku-band earth stations

n IF and L-band IFLs

n Rain-fade site diversity

n Economical 70 MHz/140 MHz links for uplink

antenna remoting, downconverter output distribu-

tion, and intersite connections for backup or

antenna diversity.

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^stCentury by con-

verting microwave signals into continuously variable

amplitude-modulated optical signals.

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.

System 8000 Fiber-Optic Interfacility Links

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.

Description (continued)

n Remote RF monitor links measure the composite

uplink signal at the uplink EIRP monitor coupler

located at the antenna’s input feed flange.

n 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 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.

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 inter-

connections 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 trans-

mit 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 with-

out 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 chas-

sis. 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.

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 exter-

nal M and C must switch the input to the backup trans-

mitter.

System 8000 Redundancy

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.
