1.2.2 3G Transmission
Grass Valley’s latest XCU is based on full digital transmission and a proven and robust power
system. The 3G transmission system consists of a dockable camera adapter that fits on Grass
Valley HD camera heads and an XCU that takes care of power, signal transport and conversion
and connection to the studio or OB van.
A wide range of 3G transmission versions is available, so there is always an option that suits
your operational situation best.
XCU 3G Triax
The XCU 3G Triax makes camera transmission fully compatible with industry standard Triax
cables. This allows the use of existing, reliable and valuable cable inventories and at the same
time increases already long cable runs with up to 25% greater distances.
3G Triax offers video transmission and remote control of cameras up to a distance of 1,500 m
(5,000 ft) and beyond, using standard 14 mm (0.55 in.) Triax cables.
XCU 3G Fiber
The XCU 3G Fiber is equipped with a hybrid fiber connector.
3G Fiber offers video transmission and remote control of cameras up to a distance of 3,000 m
(10,000 ft) and beyond, using hybrid fiber cables.
XCU 3G Dual
The XCU 3G Dual combines a Triax connector with a hybrid fiber connector.
XCU 3G Twin
The XCU 3G Twin combines a Triax connector with two dark fiber connectors.
