WARNING
Never look directly into an optical fiber. Non-reversible damage to the eye can
occur in a matter of milliseconds.
"
Do not hook up the 7708VT-4 DWDM and 7708VR-4 cards directly with a short
fiber optic cable. The 7708VT-4 DWDM card produces +7dBm of power which
will damage the receiver if connected directly.
"
Do not hook up the 7708VT-4 cards that output more than -7dBm of power
(see 7708VT-4 specifications for output power of various laser types) and
7708VR-4-H high sensitivity receiver cards directly with a short fiber optic
cable. The 7708VT-4 cards that produce more than -7dBm of power will
damage the receiver if connected directly.

Revision 1.0 Page-1
1. OVERVIEW
The 7708VT-4 is a VistaLINK
®
enabled SMPTE 292M fiber or coax transmitter for SDI, DVB-ASI or SDTi
video signals. This single card combines up to four SDI, DVB-ASI or SDTi signals using Time Domain
Multiplex (TDM) technology to transmit a single SMTPTE 292M signal over fiber or coax cable. The
companion 7708VR-4 Quad SDI Receiver demultiplexes the signals and converts them back to separate
SDI video feeds.
The 7708VT-4 and companion 7708VR-4 will transparently pass incoming SDI video feeds with embedded
AES audio or any other data in the horizontal or vertical ancillary data space. Monitoring and control of
the card status and parameters is provided locally at the card edge or remotely via VistaLINK
®
.
The fiber output is available in an assortment of optical wavelengths, accommodating standard, or CWDM
transmission schemes. (See the technical specifications in section 3 for complete information).
7708VT13-4 1310 nm FP -7dBm output, suitable for distances up to 50 Km
7708VT15-4 1550 nm DFB 0dBm output, suitable for distances up to 75 Km
There are several versions with built in isolators specifically suited to coarse wave division multiplexing
(CWDM) applications. These versions all have 0dBm output and are suitable for distances up to 75 Km.

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.

LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid input signal, if a laser fault exists, or if a local input power fault exists (i.e.: a
blown fuse). The LOCAL FAULT indication can also be reported to the frame
through the FRAME STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid input
signal is present, and the laser and board powers are good.
On the 7708VT-4, there are four small LEDs on the back of the board that indicate the presence of video
signals.
VIDEO 1 PRESENT: This Green LED indicates the presence of a valid signal on the Video 1 input.
VIDEO 2 PRESENT: This Green LED indicates the presence of a valid signal on the Video 2 input.
VIDEO 3 PRESENT: This Green LED indicates the presence of a valid signal on the Video 3 input.
VIDEO 4 PRESENT: This Green LED indicates the presence of a valid signal on the Video 4 input.

4.2. DOT-MATRIX DISPLAY
Additional signal and card status monitoring is provided via the 4-digit dot-matrix display located on the
card edge. The card-edge pushbutton is used to select which data is being displayed in the alphanumeric
display. Each time the pushbutton is pressed, the display advances to the next available display. A
message indicating what display mode is active is shown for one second. After one second without the
pushbutton being pressed, the selected display data is shown.

5. JUMPERS AND LOCAL CONTROLS
Several jumpers, located at the front of the module are used to preset various operating modes. Figure
4-1 shows the locations of the jumpers.
5.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper 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 Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position. (default)
When this jumper is installed in the Off position local faults on this module will not
be monitored.
5.2. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE: The UPGRADE jumper is used when firmware upgrades are being done to the
module. For normal operation it should be installed in the RUN position. See the
Upgrading Firmware section of this manual for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the
UPGRADE jumper into the UPGRADE position. Install the Upgrade cable provided
(located in the vinyl pouch in the front of this manual) onto SERIAL header at the
card edge. Re-install the module into the frame. Run the upgrade as described in
the Upgrading Firmware section of this manual. Once the upgrade is completed,
remove the module from the frame, move the UPGRADE jumper into the RUN
position, remove the upgrade cable and re-install the module. The module is now
ready for normal operation.

6. VISTALINK
®
REMOTE MONITORING/CONTROL
6.1. WHAT IS V ISTA LINK
®
?
VistaLINK
®
is Evertz’s remote monitoring and configuration platform which operates over an Ethernet
network using Simple Network Management Protocol (SNMP). SNMP is a standard computer network
protocol that enables different devices sharing the same network to communicate with each other.
VistaLINK
®
provides centralized alarm management, which monitors, reports, and logs all incoming alarm
events and dispatches alerts to all the VLPro Clients connected to the server. Card configuration through
VistaLINK
®
PRO can be performed on an individual or multi-card basis using simple copy and paste
routines, which reduces the time to configure each module separately. Finally, VistaLINK
®
enables the
user to configure devices in the network from a central station and receive feedback that the configuration
has been carried out.
There are 3 components of SNMP:
1. An SNMP manager, also known as a Network Management System (NMS), is a computer running
special software that communicates with the devices in the network. Evertz VL-Fiber demo Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK
®
enabled fiber optic products.
2. Managed devices (such as 7708VT-4 and 7708VR-4 cards), each with a unique address (OID),
communicate with the NMS through an SNMP Agent. Evertz VistaLINK
®
enabled 7700 series modules
reside in the 3RU 7700FR-C MultiFrame and communicate with the manager via the 7700FC
VistaLINK
®
frame controller module, which serves as the Agent.
3. A virtual database, known as the Management Information Base (MIB), lists all the variables being
monitored, which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK
®
network, see the 7700FC Frame
Controller chapter.
