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! Do not 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.

1.2 Technology
1.2.1 Unique Cradle concept
The XF Transmission Base Station system is like no other in the world. Its unique cradle can be
pre-mounted and pre-wired in a 19-inch rack, making a secure mechanical and electrical
connection, permitting the XCU Universe XF box to easily slide in and out whenever needed.
Each XCU Universe XF comes with one cradle, but additional cradles may be acquired to
extend usability across different environments, allowing you to quickly and easily transfer XCU
Universe XFs between OB vans, studios, or anyplace.
The cradle concept allows for moving boxes easily and quickly between locations such as
trucks and studios. Pre-mounted and pre-wired to eliminate cabling errors, the unique cradle
provides on-demand res for fast paced productions, resulting in less set up time and more on-
air time. Compatibility with the LDX Series and many LDK Series cameras extends the cradle's
usefulness across all types of productions.
Transmissionconnectors can easily be exchanged during production and in the field. All other
connectors are mounted on a separate connector panel in the cradle. After disconnecting
mains power and the transmission cable the box can be removed.

Installation
2.1 Rack installation
2.1.1 Installing rack mounting rails
The XCU Cradle can be mounted in most standard 19-inch video or IT rack types. The unit
needs two rack units (2 RU) of vertical space in the rack.
Install two L-shaped rack mounting rails (not supplied) that match your rack type. Refer to the
documentation of your mounting rails or rack for installation instructions.
• Make sure that both front and back end of the rails are attached to the rack. Allow a
minimum distance of 30 cm (11.8 in.) between the secured points.
• There should be a blind/untapped area in the front of the vertical rack beam where the
locking mechanism of the XCU engages the rack.
• The thickness of the horizontal leg of the L-shaped mounting rails must not exceed 2 mm
(0.08 in.) in order to leave enough space for more cradles to be mounted below the unit.
Below is an example of a rack mounting rail installed in a 19-inch rack. Note that your specific
situation may be different.
min. 30 cm (11.8 in.)
min. 12 mm (0.5 in.)
max. 2 mm (0.08 in.)

2.1.2 Installing the cradle
After mounting the rack mounting rails, install the cradle:
1. Slide the cradle into the rack so it is supported by the L-shaped mounting rails.
2. Fix the cradle to the front rack posts using four M6-screws (not supplied with the unit).
2.1.3 Transporting rack mounted XCUs
When transporting rack mounted XCUs in a flightcase make sure to take the following
precautions:
• Use proper shock absorbers for the rack to prevent damage during transport.
• To prevent any horizontal movement of the cradle and XCU during transport, make sure
there is as little horizontal clearance as possible between the cradle and the mounting
rails:
• To prevent any vertical movement of the cradle during transport, lock up the cradle
between other units and the vertical rail stands as indicated in the illustration below. Make
sure there is enough support at the back of the unit, at a minimum distance of 400 mm
from the rack front/

2.1.4 Connecting studio cabling
The studio cabling (main video outputs, control and intercom connections, studio signalling)
can now be connected according to your application and studio configuration. Refer to
“External video connectors” on page 56 for connectors and signals available on the cradle.
More information about studio signalling, control network, intercom cabling and other studio
infrastructure can be found further down this chapter.
2.2 Mounting the XCU
To mount the XCU into the cradle, proceed as follows:
• Place the XCU onto the sliding rails of the cradle, slide the unit into the cradle and push
firmly.
• Push down the right and left locking handles until they snap down.
To remove the XCU from the cradle, proceed as follows:
• Hold down the springs inside the locking handles and at the same time swing them open.
• Pull out the XCU from the cradle by pulling the XCU at its sides.
• Now the transmission and mains cables can be connected. Refer to “Connector
overview” on page 51 for connectors and signals available on the XCU.

2.3 Setting up the control network
The XCU is connected to the control network hub or router via an Ethernet cable (straight-
through, not cross-over) via the C2IP (RJ45) connector. An OCP 400 (Operational Control Panel)
and, if required an MCP 450 (Master Control PC), are also connected to the Ethernet network
via a hub or router. An OCP 400 can also be connected directly to the XCU using a (cross-over
or a straight-through) Ethernet cable.
The IP address and other options for the Ethernet connection can be set up in the XCU menu.
☞Note ☞Note
By default, the Ethernet connection is set up for Auto IP configuration.
2.4 Setting up intercom
Connect the studio intercom system to the rear of the XCU Universe XF. Both a two and four-
wire cabling can be used. In the AUDIO/INTERCOM > INTERCOM > ENG > WIRE MODE menu
select the cabling system: 2wire or 4wire.
The wiring of the panel connector is shown below for two-wire and four-wire systems.

2.5 Setting up studio signalling
Connect the studio signalling system to the rear of the XCU. The wiring of the signalling
connector is shown below:
There are several connection methods for the ISO (On Air Yellow), On Air and Call signalling
functions: dry contact, common ground, voltage level and open circuit/voltage level.
A selection in the INSTALL > SIGNALLING INPUT menu allows you to make the activity state
of the function (Active or Inactive) correspond to a particular input signal. There are two leads
for each connection - Send and Return.
2.5.1 Dry contact
☞Note ☞Note
A common return (not ground!) can be used for all three functions (ISO, On Air and Call)
If a contact is closed, the corresponding function is Active or Inactive, depending on the
