VSAT Pro System | 4000
Global Foxcom’s 4000 VSAT Pro System is a fiber-based link kit for VSAT hubs and NOCs that replaces long coaxial runs between the antenna and the equipment room. It is designed for hub layouts that require consistent signal distribution, practical commissioning, and straightforward field servicing.
Features & Benefits
- Fiber link kit for hub and NOC antenna to rack connections
- Bidirectional L Band transport 950 to 2150 MHz
- Dedicated 10 MHz reference feed to the BUC
- Lower RF loss than long coax runs
- Improved resilience to lightning, EMI, and RFI
- IP65 outdoor enclosure with conformal coating
- Hot swappable outdoor access for faster service
- 1U indoor chassis for rack installation
- Available in 50 ohm and 75 ohm variants
- FC/APC terminations on SMF 28 single mode fiber
The 4000 VSAT Pro System uses fiber between the antenna and the equipment room to address signal loss and interference challenges commonly associated with extended coaxial routing. The architecture separates the outdoor antenna interface from the indoor rack equipment, allowing the system to integrate into existing modem, LNB, and BUC signal paths without changes to surrounding RF infrastructure. This configuration supports reliable commissioning, simplified maintenance, and stable antenna-to-rack connectivity for both hub upgrades and new installations.

What comes in the 4000 VSAT Pro kit?
The kit includes a G4000 outdoor unit for antenna side installation and a 1U 7190 indoor chassis with a power supply for the equipment room.
How far can the fiber run go?
Typical engineered spans are up to 3 km on single mode fiber within the stated optical budget.
Which RF and reference signals are supported?
L Band is carried in both directions and a dedicated 10 MHz reference feed is provided for the BUC.
Does the platform support LNB power?
Yes. LNB power is available at 18 V, with an optional 13 V setting, and it is current limited for protection.
Are field service actions disruptive?
Service access is supported at the outdoor unit through hot swappable module access, helping minimize impact during field work.
What connector and impedance options are available?
The system is available in both 50 ohm and 75 ohm variants. RF interfaces use F-type connectors indoors, with F-type, SMA, or N connectors outdoors depending on configuration. Optical connections use FC/APC terminations on single mode fiber.
