ADU/FOS/MP
Fiber-optic GPS antenna splitter for secure signal transmission over long distances
ADU is an antenna distribution unit for connecting a Meinberg GPS antenna/converter (GNSS|IF|15V DC) to several Meinberg GPS receivers (up to eight receivers) via single-mode fiber lines.
The ADU system must be mounted inside the building and connected to the Meinberg GPS converter antenna via a coaxial cable.
The GOAL-S-R module is connected on the receiver side to the GPS antenna input of the receiver via a coaxial cable and can be mounted close to the connected receiver.
The two modules (ADU and GOAL-S-R) are interconnected via E9/125µm single-mode fiber. This type of antenna connection has the following advantages:
- Long antenna cable runs possible (up to 10km)
- No danger caused by overvoltage damage via the antenna cable
- Tap-proof security communication through fiber optic connection
The GOAL-S/R modules installed on the receiver side are powered by the Meinberg GPS-IF receiver via coaxial cable. The ADU/FOS/MP system installed on the antenna side requires an externally supplied voltage for its own power supply as well as for feeding the connected antenna through the built-in GPS receiver.
The system is suitable for the subsequent extension of existing Meinberg GPS systems. Ask a member of our team about systems suitable for use with a GOAL-S Antenna Link.
Key Features
