IMPORTANT SAFETY INSTRUCTIONS
The lightning flash with arrowhead symbol within an equilateral triangle is
intended to alert the user to the presence of uninsulated “Dangerous voltage”
within the product’s enclosure that may be of sufficient magnitude to constitute a
risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user
to the presence of important operating and maintenance (Servicing) instructions
in the literature ac-companying the product.

2405/2407LTA Standalone L-Band Fiber Optic Transmitter
Revision 1.1 2405/2407LTA - 1
1. OVERVIEW
The 2405/2407LTA is a fiber optic transmitter used for transporting L-Band satellite signals over fiber optic
cable. The 2405/2407LTA accepts one L-Band RF input on an F-Type connector and provides a fiber
optic output. An L-Band RF output is also provided for monitoring of the input RF signal. This port
provides a copy of the input signal prior to any manual or AGC gain control. The DC power input is via an
F-Type connector. The 2407LTA sends monitoring and configuration status information down the fiber for
viewing locally at a 7708LR receiver and remotely via SNMP/VistaLINK®. See 7708LR manual for details
on the parameters monitored. The 2405LTA does not send this monitoring information down the fiber.
Features:
• Extended L-Band frequency range - 950 to 2150MHz
• Protocol transparent - handles all video, audio and data modulation formats
• 2407LTA signal and configuration status are relayed for monitoring at 7708LR products. With the
7708LR this information can be monitored remotely through SNMP and VistaLINK®. See the 7708LR
manual for details
• Automatic and manual gain control
• L-Band monitor coaxial output
• Can inject LNB power (as provided by connected DC power supply) into the RF input cable for LNB
powering
• Can inject 22 kHz (selectable on/off) into the RF input cable for LNB local oscillator control
• -WP version provides IP65 dust and water protection for mounting outdoors without a supplemental
enclosure

2. INSTALLATION
The 2405/2407LTA comes in a die-cast enclosure with integral mounting flanges. It is recommended that
the enclosure be mounted on a flat surface with the connectors facing down. For units with the -WP
option that are exposed to the elements, while not required to prevent water ingress into the unit, good
outdoor installation practice suggests protecting connectors with a wrap of Scotch 130C rubber tape
followed by Scotch Super 88 vinyl tape, or equivalent.

2.1. 2405/2407LTA CONNECTIONS
RF IN Input F-Type connector for L-band satellite signals. This connector can also provide LNB
power and 22kHz tone back to the satellite dish.
!
If LNB POWER LED is on or flashing, there will be DC voltage for LNB power at
the RF IN connector. This can damage some test equipment.
You can turn off the LNB power by switching LNB MODE switch to the OFF
position.
MONITOR OUT Output F-Type connector provides a buffered copy of the incoming RF signal for
monitoring purposes (signal peaking, etc.)
"When unused, it is recommended that this connector be terminated with a 75 Ohm
load.
DC IN Input F-Type connector for DC power supply. Input power supply range is from 11-23 VDC.
!
Do not exceed 23VDC at the DC input connector or damage to the unit will result.
FIBER OUTPUT FC/APC female connector with the optical output from the 2405/2407LTA. 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 2405/2407LTA transmits on the 1310 wavelength unless otherwise indicated by
wavelength label.

Products
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 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.

4. STATUS INDICATORS
The 2405/2407LTA module has three LED status indicators on the front of the box to show operational
status of the module at a glance.
4.1. RF DRIVE INDICATOR
HIGH: The RF DRIVE LED will be RED when the incoming RF signal plus the module gain
is overdriving the laser. Over driving the laser will be manifested as high IM products
at the receiver.
OK: The RF DRIVE LED will be GREEN when the incoming RF signal plus the module
gain is within the normal drive levels for the laser.
LOW: In manual gain mode, the RF DRIVE LED will be ORANGE when the incoming RF
signal plus the module gain is under driving the laser. Signal to noise ratio will
suffer. In AGC mode, this LED will be ORANGE when the incoming signal drops
below the AGC hold range.
The following table provides a guide for the RF power levels that trip the LED indicators in each gain
mode. Please note the tolerance for the levels.
Nominal Input Level ( dBm ) Settin

2405/2407LTA - 8Revision 1.1
4.2. LNB POWER INDICATOR
DC PASS: The LNB PWR LED will be GREEN when the LNB power mode is set to DC
PASS. In this mode, DC input from the connected power supply is fed to the
LNB. The voltage seen by the LNB will be approximately equal to the voltage
supplied by the connected DC power supply minus 0.3VDC minus cable drop.
When the LNB PWR LED is blinking green or orange, there will be a 22khz tone present in addition to
LNB power.
!
If the LNB PWR LED is on or flashing, there will be DC voltage for LNB power at the
RF IN connector. This can damage some test equipment.
You can turn off the LNB power by switching LNB MODE switch to the Off position.
4.3. DC INPUT INDICATOR
<11V The DC IN LED will be RED when the supply voltage at the DC input is less than
11 Volts.
11V to 15V The DC IN LED will be GREEN when the supply voltage at the DC input is
between 11 and 15 Volts.
>15V to 23V The DC IN LED will be ORANGE if the supply voltage at the DC input is greater
than 15 Volts.

5. USER CONTROLS
User controls are located behind the two removable hole plugs on the front of the unit. These plugs are
threaded and may be removed and installed with a Philips head screwdriver. When installing, ensure that
the plugs are snug so as to prevent water ingress, but do not over tighten and distort the rubber washer.
5.1. GAIN
Gain adjustment is via a 16 position rotary switch located behind the GAIN ADJUST hole plug. The switch
itself is marked 0-9 and A-F, and may be rotated using a small Philips screwdriver. Each step on the
rotary switch represents a 2 dB gain change, with position 0 being AGC mode. AGC will maintain the
output of the 2405/2407LTA at a constant level even if the input signal level changes, but remains within
the hold range of –20 to –45 dBm.
Switch
Position Function
0 AGC
1 Manual Gain 2 dB

Table 5-1: Gain Adjustment Switch
"If conducting frequency response sweeps, both the 2405/2407LTA and the
companion receiver should NOT be an AGC mode and should be set to a manual
gain value.
5.2. LNB MODE
The 2405/2407LTA has the ability to inject 22khz tone as well the DC voltage supplied by the connected
power supply into the cable connected to the RF input. This allows both powering and control of the
connected LNB. Adjustment is via a 16 position rotary switch located behind the LNB MODE hole plug.
The switch itself is marked 0-9 and A-F, and may be rotated using a small Philips screwdriver.

6. +PS OPTION
When equipped with the +PS option, the 2405/2407LTA will come with an 18VDC, 44W power supply and
F-Type cable adapter. This allows the power supply to be connected to the 2405/2407LTA using an
appropriate length of coaxial cable with F-Type connectors on either end. The supply is capable of
providing power to the 2405/2407LTA and up to 400mA to the connected LNB.
!
This power supply is not suitable for exposure to the elements and must be
installed indoors or in an enclosure.
