ADU/FOS/MP - GPS Singlemode Antenna Distribution Unit

Key Features

large antenna cable distances - up to 10km. using a continuous connection with a fiber type of category OS2 (0.4dB/km)
no destructive overvoltage via the antenna cable
no unintentional monitoring possible via optical fiber
Option: Redundant power with AC/DC and/or DC power supplies

Product Description

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 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 10 km)
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 receiver side are powered by the Meinberg GPS-IF receiver via coaxial cable. The ADU/FOS/MP system installed on 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. The following GPS receivers are suitable for use with a GOAL-S Antenna Link:

and older receivers of the series GPS163, GPS164, GPS165, GPS167, GPS168, GPS169 and GPS170 (but not GPS166!).
