present at the output is user selectable among the four input signals via local or VistaLINK®
controls. Reclocking is provided at this output.
OPTICAL OUTPUT: Output SC/PC (Shown), ST/PC or FC/PC female connector. The optical output
signal at this connector contains the TDM multiplexed input HD-SDI and/or SDI/SDTi video
signals. Any ancillary data (e.g. embedded audio, closed captioning, etc) present in the input
video streams prior to multiplexing are transparently passed through to this output.
This optical output is available in 1310nm, 1550nm, up to sixteen CWDM wavelengths
(ITU-T G.694.2 compliant) and up to 40 DWDM wavelengths (ITU-T G.694.1 compliant). The
output wavelength is marked on the rear panel of each module. When connected directly to a
companion module, the output is compatible with multi-mode fiber optic cable. If not connected
directly (i.e. connected through CWDM, DWDM, WDM or a splitter/combiner) the output is
compatible only with single-mode fiber optic cable.
"
Do not hook up 7707VT-4-HS DWDM cards and any 7707VR-4-HS series cards
directly with a short fiber optic cable. The 7707VT-4-HS DWDM card produces
+7dBm of power, which will damage the receiver if connected directly.
"
Do not hook up the 7707VT-4-HS cards that output more than -7dBm of power
(see 7707VT-4-HS specifications for output power of various laser types) and
7707VR-4-HS-H high sensitivity receiver cards directly with a short fiber optic
cable. The 7707VT-4-HS cards that produce more than -7dBm of power will

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. This prevents 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.

Table 4-2: Input Modes and Signal Connections
If a new signal is connected that conflicts with the present mode setting, it will not be transmitted by the
7707VT-4-HS. The corresponding Signal Status LED will be yellow, indicating a signal conflict on that
channel. The 7707VT-4-HS will NOT drop or otherwise interrupt any of the existing signals in the event
that a new conflicting signal is connected.
The AUTO input mode will automatically select the optimum input mode (HHXX, HSSS or SHSS) depending
on the signals that are connected to the 7707VT-4-HS. If a signal is connected that the 7707VT-4-HS
cannot accommodate in any of the above modes, the Signal Status indicator corresponding to that
channel will be yellow. The 7707VT-4-HS will NOT drop or otherwise interrupt any of the existing signals
in the event that a new conflicting signal is connected.
Whether the input mode is selected automatically or manually by the user, it may be displayed by the
MODE selection under the STAT menu (see section 4.2.4).
4.2.7. Setting Video Error Detection
The 7707VT-4-HS can detect bit errors in the incoming video signals. The EDET menu item turns this
error detection on or off. When turned on, the Signal Status Indicator corresponding to a signal containing
bit errors will turn red and a trap value will be set (see section 6.4). To set the error detection mode, select
the CTRL menu item in menu level 1, then use the toggle switch to display the EDET option and press the
pushbutton to select it. Use the toggle switch to select between ON and OFF.
