Fiber Cable Overview
Fiber Optics and Fiber Optic Cable are the core technologies at the heart of the equipment.
The Telecast device features the ability to multiplex and de-multiplex a variety of video,
audio and data signals so that they can be carried over a thin strand of Fiber Optic cable for
long distances. The specific theory and operation of Fiber Optics is beyond the scope of
this document.

Managing the Fiber Optic Cable
The deployment of Fiber Optic Cables will vary greatly among users. Where the Fiber Optic
cable is permanently installed between units, such as between a campus performance
venue and a central media center, the management of the fiber optic cable will be a onetime occurrence. For those users who deploy the equipment in variable and outside
locations the considerations discussed below are important every time the Fiber Optic
Deployment system is used.
To prevent damaging your eyes, never look directly into the end of the optic fiber
while either end of the system is operating.
Always protect the ST Fiber Optic connectors when the cables are not connected. This
protects the connector from damage and the unlikely event of exposure to an operating
optical link. Keeping protection in place when the connectors are not in use will prevent
dirt and dust from entering the connector and degrading the performance of the optical
link.
It is important that you do an initial setup and test your system as soon as you receive it to
confirm proper operation and to provide training for you and your team prior to an actual
production.
It is highly recommended that you do not attempt to power up the system until all
connections are made. In particular, the Fiber Optic Cable must be connected at both ends.
If you need to power up the Fiber Optic Deployment unit, make sure that the Fiber
Connectors are protected. This will protect theconnector from damage or dirt and protects
you from damaging your eyes.
Deploying the Fiber Cable
Successful connection and management of the Fiber Cable requires you to perform four
tasks:
• Plan the route the Fiber Cable will take to the units
• Run the Fiber Cable along the planned route
• Connect the Fiber Cable Connectors at each end
• Power up the device and check the Fiber Optic Cable Links by means of the LED display
(where applicable).

Using Fiber Optic Cable
Planning the Fiber Cable Route
Planning the Fiber Cable Route
Obviously the longer the planned cable run, the more planning required. When planning
your cable route, consider the following:
• Be aware of any possible obstacles that might cause you to run short of cable. You may
need to take a more indirect, but achievable route.
• Be aware of any possible hazards to the cable.
While tactical fiber is extremely durable, it is not immune to damage. For example, you
would not want to run 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.
• Be aware of any possible physical interference with the cable that might cause it to
bend or kink to an extent causes unacceptable signal loss to occur.
• Be aware of any safety hazards.Make sure that the cable will not cause a tripping or
tangling hazard with people, animals, or vehicles.
• Decide whether the Fiber Cable is to be unspooled from the Signal Source of the device
location.
If one end of the cable needs to be moved during the production, it makes sense to
place the spool at that location. 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 first connection.

Running the Fiber Cable
Place the stationary
cable connector inside
the center of the reel prior
to unspooling the cable.
Do the following when running your Fiber Cable:
1 Make sure that both ends of the Fiber Cable are securely capped to prevent dirt and
damage
potentially cause you to lose the use of your camera while the problem is being
diagnosed and remedied.
2 If the cable run is long, or if you lose sight of the spooling-out cable reel, make sure you
ha
critical that you receive assistance to prevent the cable end from being caught or
tangled up. Don’t start reeling in the cable on your own and assume the Connector end
will make it back to home base safely.
3 When unspooling the cable, ALWAYS make sure the stationary end is securely
contained within the reel (a loose connector can bang around and be damaged).
NEVER connect the stationary end of the Fiber Cable to the local equipment and then
start unspooling the Fiber Cable. Severe damage to the cable could occur due to
extreme spiraling of the connected portion of the cable.
. ANY dirt in the connector can adversely affect Fiber Optical performance and
ve appropriate assistance in running out the cable. When retrieving the cable, it is

4 Prior to connecting the Fiber Connectors to the equipment, inspect both the Input and
Output Connectors.
If required, clean with dry compressed air or with
moistened with isopropyl alcohol. Fingerprints or other dirt on the optical connector
end surfaces will reduce the optical signal level on the fiber. If the connectors have
been properly capped during storage and movement, you will not likely have a
problem. However, if a connector has been dropped or dragged through dirt or
exposed to dust, you should cleanthe connector immediately.
5 Once the Fiber Cable has been connected, it is time to secure the Fiber Cable run. Make
e there are no cable hazards in the run. Secure the cable with Cable Guards and/or
sur
Gaffers tape to insure safety.
6 Now the system can be powered on. Plugging in Fiber Cable connectors with the
er on will not damage the system, but is not recommended because of the chance
pow
of possible damaging your eyes.
