Figure 1-2: SPL 7110-Exx block diagram
The SPL 7110-Exx transmitter is a compact plug-in module that mounts easily in Harmonic’s
HLP 4200 and HLP 4800 platform via the HMC 4001 module carrier.
For additional information on the HLP 4200 platform and HLP 4800 platform and its
associated communication and power buses, see the HLP 4200 Instruction Manual or the
HLP 4800 Users’s Guide.
1.3 Applications
The SPL 7110-Exx transmitter is designed to operate in multi-wavelength systems allowing
fiber conservation or reclamation. The 1550nm DWDM optical signal transmitted by a
SUPRALink DWDM module must be combined and separated using Harmonic passive
multiplexor and demultiplexor optical modules. A complete family of passive optical products
is available for network design.
Figure 1-3 and Figure 1-4 show two typical applications of the SPL 7110-Exx. Broadcast
signals and QAM signals from a cable modem termination system (CMTS), cable telephony, or
video-on-demand server are combined and used to drive the SPL 7110-Exx. The optical
outputs from multiple SPL 7110-Exx are combined into a single fiber using a dense
wavelength division multiplexor (DWDM).

Chapter 1 Overview Applications
© 2009 Harmonic Inc. 11 SPL 7110-Exx, Version 1.0, Rev A
Figure 1-3: Application Example 1
In both applications, the combined optical wavelengths are transported to the hub, where
they are demultiplexed and fed into multiple nodes. In Figure 1-3, the return path signal is
carried on a separate fiber (not shown) from the forward path signal. In Figure 1-4, the return
signal is carried on the same fiber as the forward path signal.
Figure 1-4: Application Example 2

Chapter 1 Overview Applications
© 2009 Harmonic Inc. 12 SPL 7110-Exx, Version 1.0, Rev A
In multiwavelength applications, the launch power into the fiber and the total fiber distance
may need to be limited and the analog content on each wavelength must be identical to
avoid detrimental non-linear fiber optic effects. Consult your Harmonic applications engineer
for more details.

Chapter 2 Installing the SPL 7110-Exx Transmitter Connecting the Fiber Cable
© 2009 Harmonic Inc. 15 SPL 7110-Exx, Version 1.0, Rev A
2.3 Connecting the Fiber Cable
To proceed with installation, connect the fiber optic cable to the transmitter output. The
optical output connector of the SPL 7110-Exx is located on the rear of the module, as shown
in Figure 1-1 on page 9.
DANGER: Invisible Laser Radiation. AVOID EXPOSURE TO BEAM. Never operate unit with a broken fiber
or with a fiber connector disconnected.
To connect fiber optic cable to the transmitter output:
1. Verify that the transmitter module has been mounted into the HLP platform, as described
in Section 2.2..
2. Determine the connector type on the SPL 7110-Exx. The standard optical connector
recommended by Harmonic is SC/APC. Other connector types can be special ordered.
3. Verify that the type of connector on the fiber cable is the same as what is on the SPL
7110-Exx, for example, SC/APC.
4. Verify that the fiber cable connector has been cleaned properly. If the fiber cable
connector needs to be cleaned, follow the cleaning procedure outlined in Section
5.1.1 Cleaning Patch Cord or Pigtail Fiber Optical Connectors on page 28.
5. Verify that the SUPRALink optical connector has not been exposed to any contamination.
If you suspect that the connector may have been exposed to contamination (for example,
by a dirty fiber cable connector), follow the cleaning procedure outlined in Section
5.1.2 Cleaning Transmitter Module Optical Connectors on page 28.
NOTE: Any contamination of either the fiber cable or SPL 7110-Exx connector can significantly degrade
optical link performance. This degradation will most likely manifest itself as poor carrier-to-noise (CNR)
performance.
6. For SC-type optical connectors, note the key characteristics of the mating connectors and
align them accordingly. Gently insert the fiber cable connector into that of the SPL 7110-
Exx until the connector clicks into place.
For FC-type optical connectors, note the key characteristics of the mating connectors and
align them accordingly. Gently insert the fiber cable connector into that of the SPL 7110-
Exx and tighten the rotating sleeve of the connector. Do not overtighten!
2.4 Connecting the RF Broadband Input
The SPL 7110-Exx broadband RF connector is located on the rear panel of the module, as
shown in Figure 1-1 on page 9.
The SPL 7110-Exx female F connector accepts a 75 ohm impedance coaxial cable
terminated with a male F-type connector. The male F connector on the cable should have a
center pin diameter in the range of 0.64 mm to 0.8 mm.
NOTE: To ensure performance integrity, use RG-59 coaxial cable. Use of a connector with a center pin
diameter greater than 0.8 mm can damage the input RF connector.
Insert the signal source connector into the SPL 7110-Exx module RF input connector and
tighten securely.
For the SPL7110S-EXX, the input video signal level must be between 15 and 20 dBmV per
analog video channel based on 78 NTSC channels with 450 MHz digital QAM channels.

Chapter 2 Installing the SPL 7110-Exx Transmitter Testing RF Signal Input
© 2009 Harmonic Inc. 16 SPL 7110-Exx, Version 1.0, Rev A
For the SPL7110C-EXX, the input video signal level must be between 16 and 20 dBmV per
analog video channel based on 41 Cenelec channels with 56 digital QAM channels..
2.5 Testing RF Signal Input
Once you have connected the RF signal source, you can use the RF monitor to verify the
presence of the RF signal input to the transmitter. The RF monitor is a test connector (female
F-type) located on the front panel of the transmitter module, as shown in Figure 1-1 on
page 9. The monitor level is 20 dB below the input level to the transmitter ±1.0 dB.

Once installed and configured, NETWatch Site Controller provides a straightforward way
to monitor and control a network of multiple SPL 7110-Exxs, either locally or remotely.
3.1 HLP 4200 and HLP 4800 Display
The SPL 7110-Exx can be configured and monitored conveniently via the push buttons and
LCD display of the HLP 4200 and HLP 4800 equipment platform.
Figure 3-1 provides a flowchart of the commands and messages in the Main menu, which is
at the top of the HLP 4200 and HLP 4800 platform interface hierarchy. In this figure, push-
button commands are framed in ovals, and resultant display messages are framed in
rectangular boxes.
Use the Main menu to scan through platform positions and select a specific transmitter
module to monitor and control. Instructions for navigating the Main menu are provided in
Section 4.4.1 Step-by-Step Setup Instructions on page 24.2
After you navigate the HLP 4200 and HLP 4800’s Main menu and select a specific SPL 7110-
Exx module, the Transmitter menu appears. The Transmitter menu is organized into four sub-
menus:
■Transmitter Status
■Transmitter Setup
■Transmitter Adjustments
■Transmitter Alarms
These sub-menus are described below in Section 3.1.1. through Section 3.1.4..
Figure 3-1 on page 19 shows the information and controls available in the Transmitter menu.
For further details, see Appendix B, HLP 4200 and HLP4800 Menu Display, which contains a
fully detailed chart of the menu display.
