e. Set up the Intercom Talk Back switches and level controls as desired. Please see the
following Section 6.4 on Page 67 for details on Intercom operation with the CopperHead
3400 Camera Unit.
4. Deploy the Fiber Cable (see the next section) – you are now ready to Power Up the system.
6.2.Connecting and Managing the Fiber Cable
Connecting and managing the Fiber Cable between the CopperHead 3400 Camera Unit and Base Station
or an intermediate power supply requires you to perform four tasks:
1. Plan the route the Fiber Cable will take between the Camera Unit and the Base Station or power
supply
2. Run the Fiber Cable along the planned route
3. Connect the Fiber Cable Connectors at each end
4. Power up the Camera Unit and the Base Station or power supply and check the Fiber Optic Cable
Link and signal strength
Planning the Fiber Cable Route
Obviously the longer the planned cable run the more planning required. It also makes a difference
whether you are running Tactical Fiber Cable or Hybrid Fiber Cable as these affect both the length and
the type of exposure the cable can endure.
When planning your cable route take into the consideration the following:
1. Possible obstacles that might cause you to run short of cable – you may need to take a more
indirect, but achievable route
2. Possible hazards to the cable – while tactical fiber is extremely durable it is not immune to
damage. An obvious hazard is running the cable across a lawn scheduled to be cut during your
live production. Make sure the empty roadway at 6AM will not be filled with heavy equipment
when it comes time to retrieve your cable
3. Possible interference (physical) with the cable that might cause it to bend or kink to an extent
that unacceptable signal loss occurs.
4. Safety hazards – make sure that the cable will not cause a tripping or tangling hazard with
people, animals or vehicles.
5. Decide whether the Fiber Cable is to be unspooled from the Base Station location or the Camera
location. Typically the reel is kept close to the base station. However if there is a chance the
Camera location may need to move further away from the Base Station after initial placement it
makes sense to place the reel at the camera end. Make sure there is enough free cable coming
out of the stationary end of the cable reel to accommodate a well-managed connection to the
camera.
Planning the cable route requires common sense and the ability to foresee the unforeseen.
