1.4.5 DigiLink system hybrid fiber configuration
A camera head with an LDK 5481/20 fiber adapter can be connected to the LDK 4700/20
base unit using a hybrid fiber cable that carries both signal and power. The maximum cable
length that can be used is 100 m (330 ft). The power consumption of the camera may reduce
the maximum length of cable that can be used, so alternatively, the power for the camera can
be supplied directly to the adapter from the optional LDK 5901 power supply.

(16,400 ft). The camera adapter must be powered locally by the optional LDK 5901 DC power
supply.
