The Model 2990 PRO L-Band Satellite Transport System pro-
vides an economical solution for transporting digital signals
for numerous satellite distribution applications, including
headend relocation, and distribution of digital broadcast sys-
tems (DBS). The system utilizes a cost-effective coax cabling
configuration to distribute the RF signals from the dish to
the transmitter and from the receiver to the headend.
The single-mode optical fiber between the 2990PRO transmitter and receiver
allows transmission distances to 35 km at 1310 nm. Furthermore, using LNB
power from the transmitter decreases the need for additional equipment at the
dish site. RF alarm and indicator LEDs allow for a quick assessment of the link’s
operational status. The Model 2990PRO L-Band Transport System, whether used
in an antenna remoting application or
in a satellite distribution role, provides for transmission of the entire DBS spec-
trum in a simplified, flexible installation environment at one of the lowest costs
found in today’s market.
