2.1.4. Handling and Connecting Fibers
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical
end face of a connector before making a connection.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that you maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that will
decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come with
cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in the
frame that does not have a suitable I/O module. For further information about care and handling of fiber
optic cable see section 3 of the Fiber Optics System Design section of this manual binder.

Revision 1.8 7705EO - 9
5.1. SELECTING THE VIDEO STANDARD
The RATE SELECT jumper J6, located at the top rear of the module, determines whether the module will
operate as a distribution amplifier with SMPTE 259M (143 to 540 Mb/s) or DVB-ASI video signals or with
SMPTE 310M (19.4 Mb/s) signals. The LOCK jumper J3 located at the front of the module also needs to
be set correctly.
RATE SELECT: To set the module to operate with SMPTE 259M or DVB-ASI signals install the jumper
in the 259M position.
To set module to operate with SMPTE 310M signals install the jumper in the 310M position.
LOCK: To set the module to operate with SMPTE 259M or DVB-ASI signals install the jumper
in the AUTO position.
To set module to operate with SMPTE 310M signals install the jumper in the AUX position.
5.2. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J27, located at the front of the module determines whether local faults (as
shown by the Local Fault indicator) will be connected to the 7700FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the PS FRAME
STATUS LED's and on the Frame's Fault Tally output) install this jumper in the On
position. On Rev 1 and Rev A boards install the jumper. (default)
When this jumper is installed in the Off position local faults on this module will not be
monitored. On Rev 1 and Rev A boards remove the jumper and re-install it so that
only one side is connected.
5.3. SETTING THE EQUALIZER WARNING THRESHOLD
The EQ trimpot R46 is used to set the threshold of the cable equalizer warning. The equalizer warning is
factory set to 250 meters of Belden 8281 cable, but may be adjusted for other cable types or cable
lengths. To adjust the cable equalizer warning threshold, connect a signal to the input of the DA using the
required length of cable. Adjust the trimpot slowly until the Equalizer warning LED comes on. You can
verify that the equalizer warning is operating correctly by removing a few meters of cable from the input.
The LED should go off.
