INSTALLATION AND SETUP GUIDELINES
RF Connector Installation
1. All RF connectors including the power port connector are standard KS-type connectors.
2. Using a 12 mm (½ inch) wrench, remove port covers from RF ports and power port on the housing base.
3. The center conductor seizure screws (Phillips screw) are located through the module. Loosen, but do not remove the
seizure screw.
4. Measure the stinger to verify that it is 1.0 inches (25 mm).
5. Apply shrink tubing to weatherproof the finished connection. Slip a section of shrink tube
over the end of the cable now.
6. Insert KS connector and cable to the housing base and tighten connector. KS connectors
should be tightened as per manufacturers specifications.
7. Using a Philips screw driver tighten the seizure screw.
8. Position the shrink tube over the connector and apply heat to shrink it in place.
Powering
1. The LBLE100A can be powered with HFC power supply AC input between 40-90 VAC. Or by 220 VAC mains (optional).
2. For HFC powering 40-90 VAC, the amplifier is powered either through the 60Vac port or any RF port. To direct power
towards output/input ports, please refer to the section “AC Power Director”.
CAUTION! AC voltages in the range of 40-90 VAC present. Shut down external AC power before connecting or disconnecting power
cables to the amplifier.
AC Power Director
1. AC HFC power can be sent out via output/input ports by turning the IN/AC and
OUT/AC jumper to ON position.
2. Check the system maps to determine which ports should pass power. Turn the
IN/AC or OUT/AC jumper between OFF and ON as required.
For instance 1: To direct power between IN/AC port and OUT1/AC port, switch
both the jumpers IN/AC and OUT1/AC to ON position.
For instance 2: To direct power between 60Vac port and OUT1/AC port, switch
only the jumper OUT1/AC to ON position.
Forward and Reverse Path Set-Up
1. Gain & Cable Slope Controls are reachable under the housing lid. Refer to layout scheme on the cover plate under the
housing lid for controls adjustment.
2. This product is shipped with default 0 dB pads for all forward and reverse plug-in attenuators. Forward input stage equalizer
has a 0 dB pad by default. Forward inter-stage equalizers are 9 dB pads by default. And the reverse equalizer is a 0 dB pad
by default.

3. Before applying power to the amplifier make sure that the forward input level to the amplifier is not too high or damage to
the amplifier might occur. To be on the safe side, you should select the input attenuator to be a max. value (eg:20 dB)
before powering the LBLE100A.
4. Plug a 0dB JXP pad into the inter-stage equalizer socket.
5. Now apply power to the amplifier and measure the amplifier forward output level at the 20 dB output test point. If it is very
low then adjust the value of input attenuator until the desired output level is reached at the highest operating frequency.
Remember that the level measured at the test point is 20 dB lower than the real signal level.
6. Install the appropriate value JXP pad into the forward input equalizer socket to adjust the output level to be flat across the
full bandwidth. When the output level is flat then the input signal level will be flat too because the inter-stage equalizer is
0dB. Under this condition there will be best CNR across the full bandwidth.
7. If you plan to use the default setup then install the 9dB JXP pad back into the inter-stage equalizer socket. If your designer
has chosen a different output slope for the amplifier then install the appropriate value. Check that the forward output slope
is 9dB (default) or as set by your system planner.
8. Repeat the previous steps for each forward output port.
9. If you are having trouble obtaining the expected output levels then check the input test point to verify that the levels are as
expected at the input of the amplifier. The forward path set up is complete.
10. For the reverse path, inject into the forward output test point test carriers with the system design input signal level plus 20
dB (because the test point has 20 dB loss) at each end of the upstream band.
11. Verify that the upstream reference test point (Note: this is commonly called the “X point” and it is measured at your node, or
optical receiver, or at the 1st downstream amplifier. Consult with your system designer) has the proper upstream output
signal levels. If it does not then select the appropriate JXP pad values and install them in the reverse amplifier output
attenuator and equalizer sockets.
12. If the levels arriving from each port are not equal then use the reverse input attenuation sockets to balance them.
13. Record the in/out operating levels and the pad and equalizers used in this station.
Closing the Lid
1. Before closing the lid, make sure that no foreign matter, dirt, or chips or stands of the grounding mesh wire interfere with the
sealing surface.
2. Tuck any strand loose ends back into the mesh channel.
3. Verify the power supply cable is connected and cannot interfere with the sealing surfaces.
4. Tighten the lid bolts gradually alternating diagonally opposite, to avoid undue stress or warp in the housing. Use a 13 mm
wrench.
5. The lid bolts must be tightened to the specified 40 to 120 inch-pounds (in-lb) or 4.5 to 13.6 Nm to ensure proper closing.
The required torque is easily met using a 13 mm wrench but cannot be reached by using a nut driver.

(0 dB for attenuator & 9 dB for equalizer factory
pre-installed)
JXP pads are applicable for both attenuator and
equalizer funcions.
• JXP style are rectangular attenuators / pads with pins arranged
in-line (0.125 inch ctr. - ctr. spacing).
Pins are 0.038 inch diameter.
JXP style attenuators / pads can be inserted in two ways (flipped
180 degrees), and provides the same performance either way.
