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

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.

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.
