3 Introduction
3.1 Overview
The small and adaptable ODN2000 Optical Distribution Node with two amplified RF ports has
been designed to affordably deliver interactive CATV and high capacity DOCSIS services. The
ODN2000 is a high performance network device engineered to provide the highest quality
transmission of HD video, data, and VoIP services.
The ODN2000 is currently equipped with a Gallium arsenide (GaAs) module that offers a
cost-effective and flexible solution to expand networks. The optical node offers two high power RF
outputs, each with over 1 GHz of bandwidth.
The ODN2000 deep-fiber node is perfect for the last mile in broadband networks. The small and
rugged design makes this unit ideal for fiber-to-the-apartment and fiber-to-the-curb applications.
Having versatile modular components allows the ODN2000 to be utilized in many different phases
of network deployment. As the network grows, the ODN2000/LE2000 can be upgraded.
Unmatched flexibility, combined with a robust housing, makes this a reliable product for designing
long-term HFC solutions. Additionally, Node+0 support allows for a reduction in amplifiers,
improved reliability, and lower maintenance costs, as well as additional options for future
cost-effective upgrades.
The optional DOCSIS transponder remotely monitors and manages the ODN2000 to simplify
system maintenance and reduce maintenance costs.
The LE2000 is the basic amplifier model and can be upgraded to a 2-port fiber node (into the
ODN2000) by adding the optional reverse transmitter module and forward receiver module.
3.2 Features
Advanced Gallium Arsenide (GaAs) RF hybrid technology provides excellent
performance with two individually amplified high-level outputs with more than 55 dBmV
each at 1000 MHz
High output power supports Node+0 architecture
Can be seamlessly upgraded from an RF amplifier (LE2000) to an optical node
(ODN2000)
Return-path lasers are available for 1310 nm or for CWDM applications on one return
fiber at 1470/1490/1510/1530/1550/ 1570/1590/1610 nm
Optical transmitter/receiver modules and RF amplifier can be individually installed,
removed, or replaced. The modular design reduces downtime and simplifies
maintenance
Standard attenuator/equalizer pad to control both attenuation and equalization

4.6 Attenuator/Equalizer Pad
Figure 4-6 Attenuator/Equalizer Pad
Attenuator pad ODN20-ATT-xx is used in both ODN2000/LE2000 in RF output attenuation and
equalization. If the pad is used as an equalizer, "xx" indicates an equalization value. If the pad is
used as an attenuator, "xx" indicates an attenuation value.
Figure 4-7 shows equalization slope characteristics. If an equalizer value "xx" is set to zero (0 dB
equalization), there will be no RF attenuation or frequency-dependent variations in RF output
levels. If an equalizer value other than 0 dB is used, there will be some inherent insertion loss
introduced along with the equalization slope. The slope value between the lowest (b45) and
highest (bG) frequencies corresponds to the equalization value. As the use of an equalization value
other than 0 dB may cause slight RF output attenuation even at the highest frequency, RF output
level at bG may be lower than that at aG.
Table 4-6 outlines the approximate attenuation introduced by ODN20-ATT-08 and ODN20-ATT-12
across a range of frequencies.

5.3.3 Cable Routing
5.3.3.1 Applying AC Power
The ODN2000 may be directly line powered via the dedicated 60V AC power input. When
plugging in the power connector, please make sure that the center pin is between 35 and 40 mm in
length when measured from the seating area of the connector to the tip of the center pin. If the pin
is longer, there is a risk of damaging the ODN2000.
A fuse must be plugged into breaker F4 to provide internal power.
Figure 5-3 The Center Pin of a Connector
Figure 5-4 Fuse
Follow the procedure below to supply 60 Vac AC power to the ODN2000:
a) After removing the protective cap, insert the pin connector into the ODN2000 power
supply port. Ensure that the pin is connected into the power supply on the PCB rated at
60 Vac. Before inserting the connector, affix an O-ring to seal the connection and prevent
water from entering.
b) Tightly screw the connector into the power supply port.
c) Attach the 60 Vac power adapter cable to the connector.
d) Ensure that a fuse is inserted into breaker F4.
e) Verify that the power module status LED is ON (GREEN). GREEN indicates that the
power module is on; if the LED indicator is OFF, check for any problems with the power
adapter or power supply.
f) Verify that the forward path receiver and return path transmitter power supply LED
indicators (PWR) are ON (GREEN). GREEN indicates that the module is powered; if the
LED indicator is OFF, check whether the power module, power adapter, and power
supply are functioning normally.
5.3.3.2 RF Input/Output Cable Routing
The ODN2000 RF output ports 1 and 2 are used for forward path output signals and return path
input signals. External RF connectors should be inserted into these ports. Please make sure that
the center pin is between 35 and 40 mm in length when measured from the seating area of the
connector to the tip of the center pin (Figure 5-3 in Section 5.3.3.1 Applying AC Power).
If the node is used to supply power to cascaded equipment, insert fuses into breakers F1 and F2
as required for the RF output ports.

Note:
If outgoing power is not needed, remove the fuses to avoid damaging any internal components.
5.3.4 Optical Stub Cable
General Warning
CAUTION:
Equipment installers are responsible for the correct installation of
optical stub cables, optical fibers, and all RF terminators. Failure to
properly adhere to the instructions and recommendations herein may
affect RF performance or cause the optical node to fail. This type of
damage voids the warranty provided by Pacific Broadband Networks.
Optical connector ferrules should be no longer than 1.5 cm in order not
to affect the node operation.
Note:
Heat the ODN2000 node prior to installation of optical stub cables. Make sure to run enough
optical fiber length inside the node so that it is not taut when opening the case.
The optical modulation index (OMI) of a PBN LTM13 laser transmitter module is 4%1 (factory
setting).
5.3.4.1 Optical Input Port Cable
The optical input cable is connected to the ODN-FR via the ODN2000 optical input port. The
ODN-FR allows an optical input level between −5dBm and -3dBm. It has OAGC range between
−4dBm and -2 dBm and output level of 20 dBmV.
Optical Input Port Cable
Follow the procedure below to install the optical input cable:
a) Before connecting fiber to the receiver, measure the optical input level with an optical
power meter. The optical input level should be between −5 dBm and +3 dBm (level
between−2dBm and -2 dBm is recommended). Higher optical input levels may cause
damage to the optical receiver tubes.
b) Insert the optical cable into the ODN2000 optical input port.
c) Mount the waterproof conduit and place the fiber cable end in the optical fiber module.
The sealing O-ring must be on the connector and in good condition. Apply heat shrink
tubing or sealing tape.

Figure 5-5 Optical Stub Cable Sealing
d) Use a multi-meter to measure the actual optical input level at the ODN-FR optical power
test point (OPT TP). The conversion from optical input level (WIN) in dBm to Volts at the
optical input test point (V
TPI
) is:
𝑊𝐼𝑁= 10 lg 𝑉
𝑇𝑃𝐼
e) Ensure that the optical input level is within the acceptable range. If it is too low or too high
(indicated by an ORANGE or RED receiver optical power LED indicator), adjust the
optical input level and repeat the steps d-e until it is within the acceptable range (indicated
by a GREEN receiver optical power LED indicator).
f) Measure RF output level at the ODN-FR RF output test point. The forward RF output
level should be 20 dBmV.
Setting the Forward RF Output Level & Slope
Follow the procedure below to set up the forward RF output level and slope:
a) ODN-FR RF output is the RF input for the RF amplifier. Factory set to 20 dBmV at 547.25
MHz.
b) Place equalizers in the “FWD IN EQ”, "FWD EQ1", and "FWD EQ2" locations on the RF
amplifier. "FWD IN EQ" is the main circuit equalizer and can be simultaneously used for
equalization of two output ports. "FWD EQ1" and "FWD EQ2" are branch circuit
equalizers and are used separately for equalization of second output ports. Set
equalization values to 0 dB to ensure a flat forward RF output level.
c) Place 0 dB attenuators in the "FWD IN PAD", "FWD PAD1", and "FWD PAD2" locations
on the RF amplifier. Measure RF output levels at the "FWD OUT1" and "FWD OUT2" test
points and select the desired equalization slope values and characteristics.
d) Place attenuators in the “FWD IN PAD”, "FWD PAD1", and "FWD PAD2" locations on the
RF amplifier. Output test point should be 20dB below each of the main output ports.
Measure to ensure that the level at this point is no more than 50dBmV at 547.25 MHz.
e) Measure RF output levels at the "FWD OUT1" and "FWD OUT2" test points to check
whether they meet requirements.
f) If Ports 1 and 2 are used as a forward power feed, please insert fuses into respective
locations (F1 and F2).

Note:
Please terminate unused port with a 75 Ω terminator.
Setup Example for Forward RF Output Levels & Slope
Condition
Output Requirements
Optical input level of −1 dBm
Required output power for Ports 1 & 2 is 45 dBmV at 547.25 MHz
Equalization on Ports 1 & 2 is to be 0 dB
Port 1 is used for providing power
The following setup is recommended:
a) ODN-FR optical input level is set to the nominal level of −1 dBm. ODN-FR RF output level is
set to 20 dBmV at 547.25 MHz, i.e., the amplifier's RF input level is 20 dBmV at 547.25 MHz.
b) Place 0 dB equalizers in the “FWD IN EQ”, "FWD EQ1", and "FWD EQ2" locations on the
RF amplifier.
c) Place 0 dB attenuators in the "FWD IN PAD", "FWD PAD1", and "FWD PAD2" locations
on the RF amplifier. Measure Port 1 and Port 2 RF output levels at the "FWD OUT1" and
"FWD OUT2" test points. For this example, assume the RF levels are found to be
30 dBmV at 547.25 MHz, i.e., RF output levels present at Ports 1 and 2 are 50 dBmV at
547.25 MHz.
d) Place a 5 dB attenuator in the "FWD IN PAD" location on the RF amplifier and measure
RF output levels. For this example, assume the RF levels are found to be 25 dBmV at
547.25 MHz, i.e., RF output levels present at Ports 1 and 2 are 45 dBmV at 547.25 MHz.
e) Place a 15 Amp fuse in the F1 breaker to allow power to pass through Port 1.
5.3.4.2 Optical Output Port Cable
Setting the Return RF Input Level & Slope
Prior to connecting the optical cable to the optical output port, use the following procedure to set
the return RF input level and slope:
a) Measure return RF input levels at "RET IN1" and "RET IN2" test points.
b) Place equalizers in the "RET EQ1" and "RET EQ2" locations on the RF amplifier. "RET
EQ1" and "RET EQ2" are branch circuit equalizers that are used separately for
equalization of RF input and output signals. Set equalization values to 0 dB to ensure a
flat return RF input level.
c) Place 0 dB attenuators in the "RET PAD1", "RET PAD2", and "RET PAD3" locations on
the RF amplifier. Measure return path output levels at the "RET OUT" test point.
d) Compare RF input and output levels obtained from "RET IN1" and "RET OUT" test points,
as well as those obtained from "RET IN2" and "RET OUT" test points. Determine
attenuation values and slope characteristics for "RET EQ1” and "RET EQ2" equalizers.
Page 30
ODN2000/LE2000 User Manual
Pacific Broadband Networks Page 30 of 36
e) Based on the selected equalization parameters, set the attenuation values for "RET
PAD1", "RET PAD2", and "RET PAD3" attenuators to achieve 37 dBmV1 ODN-RT RF
input level. Consider the loss introduced by the return combiner.
f) Place attenuators with selected attenuation values in the "RET PAD1", "RET PAD2", and
"RET PAD3" locations.
g) The RF test point on the ODN-RT should be used to verify that the correct RF signal level
is being received. If the RF input level deviates considerably from the required level of 37
dBmV, repeat steps e-g.
Note:
RF amplifier's return gain is set to 26 dB.
Optical Output Port Cable
Procedure to install the optical output cable:
a) Prior to connecting the optical cable to the optical output port, use a multimeter to
measure the actual optical output level at the ODN-RT optical power test point (OPT TP).
The conversion from optical output level (W
OUT
) in dBm to Volts at the optical output test
point (V
TPO
) is:
𝑊
𝑂𝑈𝑇
= 10 lg 𝑉
𝑇𝑃𝑂
b) Compare the optical output level obtained from the test point with the nominal value set
for ODN-RT. If the difference between the two is small, proceed to the next step; if the
difference is big, please contact PBN’s qualified service personnel.
c) Connect the optical fiber to the ODN2000 optical output port.
d) Mount the "waterproof pipe" and place the fiber cable end in the optical fiber module. The
sealing O-ring must be on the connector and in good condition. Apply heat shrink tubing
or sealing tape (Figure 5-5).
5.3.5 Closing the Node
Before commissioning the node, please check that the following screws are firmly and securely
tightened.
Two mounting screws on each optical receiver.
Two mounting screws on each optical transmitter.
The mounting screws for any optional modules.
The 2 main chassis mounting screws.
Some of the module mounting screws have metal spacers. They should be checked to ensure that
they are present and are secured so they are screwed all the way in and are touching the module.
1
The optimal RF input level for the return-path transmitter is 37 dBmV at 6% OMI.
Page 31
ODN2000/LE2000 User Manual
Pacific Broadband Networks Page 31 of 36
When installing a module, tighten the mounting screws in steps.
Prior to closing the node, inspect the surfaces of the metal mating edge and the opposing rubber
sealing gasket. The ridge must be continuous and not damaged or scratched in any way. The
rubber-sealing gasket must also be in good condition. Ensure all cables and optical fibers are clear
of the edges of the lid and base. Refer all repairs to Pacific Broadband Networks’ qualified service
personnel.
Where an ODN2000 plug-in module is used, spiral binding should be used to bind together the
power cable and the two RF cables (Figure 5-7) to reduce the possibility of them being caught
between the lid and base when closing.
Once all the above steps are completed, the node can be closed. When closing the node, tighten
the mounting screws in the order shown in Figure 5-8 (12341).
Note:
The IP67 rating of the ODN2000 is dependent on the proper sealing of all external node
interfaces. This includes the optical stub cable and all RF connectors.
