CAUTION

If the LNB POWER LED is on, there will be DC voltage for LNB power at the RF

INPUT connector. This can damage some test equipment. The user can turn

off the LNB power under using the card-edge control system under the LNBV

menu item. See section 6.1.8 for details.

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. INSTALLATION

The 7708LT comes with a companion rear plate appropriate for a 1RU, 3RU or standalone enclosure as

specified at the time of order. SC/UPC, SC/APC, ST/UPC, FC/UPC, FC/APC or ST/UPC optical

connectors are available and the type specified at the time of order will be installed. For information on

mounting the rear plate and inserting the module into the frame, see the 7700FR manual for detailed

instructions.

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.
