Setting Up a System
There are two basic ways in which SHED and HDX's and HDX's can be used to augment your
HD camera systems and both concern how the camera is ultimately powered.
In a Passive set-up, a SHED and HDX-BS is connected to a SHED and HDX-C with two
singlemode fibers (
Figure 2-1 ). In this configuration, the camera head must be locally
powered via a battery or a suitable local power supply.

In an Active configuration, the SHED and HDX-BS is connected to an HDX via two
singlemode fibers and the HDX supplies power to the camera through up to 100m of
SMPTE Hybrid Cable (
Figure 2-2 ).

In each case, the SHED and HDX-BS returns an electrical signal to the base station that
facilitates the operation of the camera even though there is no physical copper connection.
The SHED and HDX-BS requires no external power supply.
