Cleaning fiber-optic connectors
WARNING
Never clean an optical connector attached to a fiber that is carrying light.
Particles of foreign matter on the tip of a ferrule can have a disabling effect on fiber-optic
transmission. Fiber-optic connectors need to be cleaned every time they are mated and
unmated; it is essential that fiber-optic users develop the necessary discipline to always clean
the connectors before they are mated.
Use a commerially available cleaning kit specifically designed for fiber-optic connectors and
follow the manufacturer's instructions carefully.
• The connector sections to be cleaned include the tips and sides of ferrules, the interior
walls of alignment sleeves, and the interior and exterior of connector shells.
• For plugs, the interior surfaces of alignment sleeves and the tips of ferrules are to be
cleaned with a cleaning stick treated with the appropriate fluid. (Cleaning sticks with a
slender design are available that allow alignment sleeves to be cleaned without having to
detach them.)
• For jacks, it is important to clean both the tips and sides of the completely protruding
ferrules.
• Both the male and female connector shells tend to attract dust and metal particles, so it is
important to clean both the insides and outsides.
• The fiber end face and ferrule must be absolutely clean before it is inserted into a
transmitter or receiver.
• Mate the connector immediately! Don't let the connector lie around and collect dust
before mating.
• Air can be used to remove lint or loose dust from the port of a transmitter or receiver to be
mated with the connector. Never insert any liquid into the ports.

Base station earthing
Metal strap
VEPE
The rear of the base station power supply unit has two separate screw terminals for protective
earth
The protective earth terminal is internally connected to the protective earth conductor of the
power cable. In normal circumstances the connection between the protective earth and the
video earth should not be broken. If required, the central earth connection wire of the studio
can be connected to terminal PE in accordance with VDE regulation 0800/part2.
Only if the studio (or OB van) is equipped with separate protective and video earth systems
may the metal strap be removed. Under these circumstances the video earth terminal must be
connected to the central functional earth potential (video earth) of the studio. This earth
potential should have functional protective and noiseless earth (FPE) qualities as stated in the
VDE regulation 0800/part2. A low impedance interconnection of both earth conductors must
be provided at the central studio earthing point.
(PE) and video earth (VE). These are normally connected by a metal strap.

The 3G Fiber Transmission System is the perfect interface between your HD camera and the
rest of your system. The heavy-duty base station provides many features in a compact package
while the camera adapter provides maximum freedom of movement.
LDK 4410 + LDK 5420 3G Fiber Transmission System User’s Guide (v1.0) 11
3G Fiber transmission offers video transmission and remote control of cameras up to a
distance of 4,000 m (13,120 ft), using hybrid fiber cables.
Transmission quality can be precisely monitored before and during operation right from the
OCP 400 operational control panel.
1.2.2 Dockable adapter
The dockable principle allows a choice of transmission and thus the greatest flexibility and
cost-effective solutions in multiple applications.
1.2.3 Base station
The base station is only 2U high yet offers full broadcast functionality and quality. The low
height means that rack space is saved. Its low power consumption and efficient internal
cooling eliminate the need for space between adjacent units. Sliding rails are additionally
available for easy access to the back panel. The wings on either side of the back panel protect
all connectors from damage, including the Fiber connector. The Fiber connector itself can
easily be mounted at different angles to suit all mounting requirements.
Chapter 1 - Introduction
1.2.4 Operational controls
You can access the base station menu, which contains all operational settings, from an
Operational Control Panel. In addition to the operational menu, the installation and service
menus can be activated from the base station by pressing a switch behind the front panel. The
base station is compatible with all existing control system components.
An OCP 400 operational control panel can be connected directly to the base station using a
cross-over Ethernet cable.
Full camera control is provided via a C2IP Ethernet-based control network.
1.2.5 Intercom
The communication facilities provide for two-wire or four-wire high quality intercom signals.

and selecting MENU OFF.
Making changes
To find out where to change a function, consult “Base station menu” on page 47to find out
under which menu group or subgroup the function is located. If the cursor points to an item
(and there are no double arrows to indicate a sub-menu) then the item pointed to has a value.
The value can be:
• a toggle value (only two values)
• a list value (more than two values)
• an analogue value (variable from 00 to 99)
• or unavailable (---).
If the value is unavailable it cannot be changed. This is indicated by three dashes (---). This can
LDK 4410 + LDK 5420 3G Fiber Transmission System User’s Guide (v1.0) 25
occur, for example, when a function is switched off. The analogue values associated with that
function are then unavailable. If there are only two values associated with the function, then
