1. OVERVIEW
The 7708LT is a fiber optic transmitter for RF signals in the extended L-Band frequencyrange and below,
for frequencies such as over-the-air DTV. It accepts a single RF input on coaxial cable and provides a
single output for optical transmission. An RF monitor output provides a convenient means of obtaining
peak satellite signal strength, or additional signal distribution.
Gain may be adjusted manually or managed automatically via AGC. With SmartMON™, incoming RF
signal strength, LNB current, and other data are relayed over the fiber output for monitoring through
SNMP/VistaLINK®at the fiber receiver (requires SmartMON™ capable companion fiber receiver). LNB
power with selectable 13/18V DC and 22 kHz tone is also provided.
Features:
•Extended frequency response for L-Band and other frequencies
•Protocol independent design - transports all modulation formats
•High power +11 dBm DWDM laser option for extended reach on long-haul applications
•LNB power with selectable 13/18V DC
•LNB current limit & short circuit protection
•LNB current monitoring
•22kHz tone on/off for LNB local oscillator control
•RF monitor output for signal peaking and signal distribution
•Manually adjustable gain
•AGC mode
•The 7708LT occupies one card slot and can be housed in a 1RU frame that will hold up to 3
modules, a 3RU frame that will hold up to 15 modules or a standalone enclosure which holds 1
module
•SmartMON™ capability provides remote status monitoring via SNMP without a separate data
connection
•VistaLINK®capability is available for monitoring and control when modules are used in a 3RU
7800FR frame and a 7700FC VistaLINK®frame controller is installed in slot 1 of the frame.

2.1. 7708LT CONNECTIONS
FIBER OUTPUT: SC/UPC, SC/APC, FC/UPC, FC/APC or ST/UPC female connector with the optical
output from the 7708LT. This connector should be connected to the FIBER IN
connector of an appropriate Evertz companion receiver model at the destination
end with a suitable fiber optic cable. The 7708LT may transmit 1310nm, CWDM or
DWDM wavelengths as indicated by the part number on the card ejector. The
standard connector type is UPC. This connector type is compatible with standard
PC connectors, but for optimal return loss performance, Evertz recommends the
use of UPC fiber terminations throughout the system. The optional APC
connectors provide further enhanced return loss performance, and when specified,
should be used throughout the system.
RF IN: Input connector for RF signals. This connector can also provide LNB power and 22
kHz tone back to the LNB.
The RF input is protected to
the same degree as other professional RF devices,
and will withstand a degree of ESD from handling, etc.
Regardless, proper
precautions should be taken during handling, such as the use of static bags and
wrist straps. The input is not protected against lightning or other coupling of
large energy spikes.
If the installation is such that the RF input may be
susceptible to spikes (e.g. direct connection to the antenna/LNB) then
appropriate supplemental surge protection should be installed (e.g. Polyphaser).
RF OUT: Output connector provides a buffered copy of the incoming RF signal for monitoring
purposes (signal peaking, etc.) or coaxial distribution. Although not essential, if this
connector is to remain unused, it is recommended that it be terminated with an
appropriate 75 Ohm or 50 Ohm load.

2.2.4. 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
facet 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 the user maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that
will decrease the maximum attainable distance of the fiber cable. Evertz fiber optic modules are
equipped with lockout devices that prevent the user from damaging the fiber connector by installing a
module into a slot in the frame that does not have a suitable rear plate installed.

4. STATUS INDICATORS
The 7708LT has eight LED status indicators on the front card edge to show operational status of the card
at a glance. See Figure 5-1 for LED locations.
Two large LEDs on the front of the board indicate the general health of the module:
LOCAL FAULT: This red LED will be on during the absence of a valid RF input signal (too
low, too high or out of AGC range), an LNB short/overload, or if a local
internal power fault exists (i.e.: a blown fuse). Whether or not this LOCAL
FAULT indication is reported to the frame may be selected by the FRAME
STATUS jumper (see section 5.1).
MODULE OK: This green LED will be on when the RF input signal is within range, LNB
power conditions are normal and the board power is good.
There are six small LEDs that indicate the status of the input RF signal, LNB, and AGC mode signals.
RF HIGH: This red LED will be on when the input RF signal is higher than the RF high
threshold setting.
RF OK: This green LED will be on when the input RF signal is within threshold
settings.
RF LOW: This yellow LED will be on when the input RF signal is lower than the RF
low threshold setting.
GAIN MODE: This LED is on when AGC mode is enabled and off when Manual mode is
enabled. It will be green when power levels are within the AGC hold range
and a constant RF output level is being maintained. It will be red if power
levels are either above or below the power levels required for the AGC
circuit to be able to maintain a constant level.
LNB MODE: This LED is on when LNB power is ON. It will green when LNB is active and
OK (no short). It will be red when an LNB short or overload is detected (fault
present).
SQUELCH MODE: This LED is on when squelch is enabled. It will be green when squelch is
enabled but not active. It will be red when squelch mode is enabled and the
output signal is squelched.

5.2. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J3 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 LEDs 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.
5.3. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE: The UPGRADE jumper J5 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.

7700 MultiFrame Manual

Page-12 Revision 1.1
To upgrade the firmware:
1. Pull the module out of the frame.
2. Move the UPGRADE jumper into the UPGRADE position.
3. Install the Upgrade cable provided (located in the vinyl pouch in the front of this manual) onto the
SERIAL header at the card edge.
4. Re-install the module into the frame.
5. Run the upgrade as described in the Upgrading Firmware section of this manual.
6. When 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.

If installed in a frame with a 7700FC frame controller, the 7708T may also be
conveniently upgraded through Evertz VistaLINK®
PRO, without service interruption.
Consult VistaLINK®PRO documentation for details on this feature.
5.4. FACTORY AND BDM JUMPERS
When shipped from the Evertz facility, the FACTORY and BDM jumpers will not be installed. These
jumpers should not be installed for any reason. If jumpers are on these positions they should be
removed.
