Configurations
3.1 HD Fiber configuration
The HD Fiber system allows video transmission and remote control of cameras up to a
distance of 4,000 m (13,200 ft) and beyond, using industry standard fiber optic cable. It is
based on 30 MHz full-bandwidth 4:2:2 transmission (Y/Cr/Cb components).
A camera head with the LDK 5880 HD Fiber adaptor is connected to an LDK 4582 HD Fiber
Base Station using a fiber optic cable. The maximum length of cable that can be used without
significant degradation of the video signal is 4,000 m (13,200 ft).
The double side band modulation technique used in combination with Y/Cr/Cb transmission
ensures linearity, resolution and an optimal signal-to-noise ratio over the maximum cable
length. Bandwidth efficient channel combining and equalization techniques minimize cross-talk
and interference. Teleprompter and viewfinder signals maintain high performance with
relatively long cable lengths.
The communication facilities provide for two-wire or four-wire high quality intercom signals.
Full camera control is provided via a C2IP Ethernet-based control network.
The power supply is applied to the Base Station and via the hybrid fiber optic cable to the
camera. An OCP 400 operational control panel can be connected directly to the Base Station
using a cross-over Ethernet cable.
