1.2 Description
The PWL 4100S transmitter is a compact plug-in module designed for use in
the Harmonic HLP 4200 equipment platform. An HMC 4001 module carrier is
needed to mount the transmitter in the platform. Harmonic has optimized the
PWRLink II family of transmitter modules for high-performance transmission
of RF broadband information over optical fiber networks.
The PWL 4100S has the following key features:
• Transmission bandwidth from 45 to 1003 MHz
• Optical performance with 80 NTSC (System M) analog channels plus
additional digital loading
• Internal monitoring and control using 32-bit microprocessor
• Local control of operating parameters—provided by the HLP 4200
platform
• Remote control and monitoring—provided by NETWatch Site Controller

Overview

• Autosetup feature that adjusts RF pad for optimum modulation
performance
• Automatic gain control and manual gain control modes of operation
Figure 1-1 shows front and rear panel features of the PWL 4100S transmitter
module.
Figure 1-1. PWL 4100S front and rear panel features
Transmitter performance is optimized by combining state-of-the-art 1310 nm
distributed feedback (DFB) laser technology and patented pre-distortion
linearization circuitry. Harmonic has designed the PWRLink II family for
integration into networks with advanced element management systems; each
transmitter module employs a microprocessor-based communication and
monitoring architecture. Figure 1-2 is a block diagram of the PWL 4100S
transmitter.
The transmitter’s microprocessor continuously monitors and controls all
critical transmitter parameters in order to optimize performance over both
time and temperature changes. The microprocessor-controlled parameters
include:
• Input signal attenuation pad
• Laser power, temperature, and bias
• Electrical circuit temperature and setpoints

The PWL 4100S transmitter is a compact plug-in module that mounts easily
in Harmonic’s HLP 4200 platform via the HMC 4001 module carrier. See
Figure 1-3 for a functional diagram of the HLP 4200 platform. The transmitter
module draws power from the platform’s 24 VDC power bus, and
communicates with the platform controller via the platform communication
bus.

For additional information on the HLP 4200 platform and its associated
communication and power buses, see the HLP 4200 Platform Product Manual.
For further information on the platform controller and power supply options,
see the CPS 4200 or CPS 4248 manual.
1.3 Applications
The PWL 4100S transmitter is designed to operate alone or with other
systems, depending on the application:
• Alone, in local distribution and narrowcasting applications
• In combination with Harmonic’s MAXLink™ 1550 nm transmission
system, for complete broadband network solutions
The PWL 4100S provides an ultra-linear RF input-to-optical output (1310 nm)
response for the simultaneous transmission of analog video and digital
signals in the 45 to 1003 MHz frequency band.
The 1310 nm optical signal transmitted by a PWRLink II module can be
received by optical receivers and nodes manufactured by Harmonic or other
major broadband equipment manufacturers. To learn more about equipment
compatibility and broadband network design and optimization, contact
customer service. See Appendix D, Harmonic Inc. – Offices .

Installing the PWL 4100S Transmitter
This chapter describes how to:
• Receive and inspect the PWRLink™ II 4100S Series Optical Transmitter
• Install the transmitter module in the HLP 4200 platform
• Connect the fiber cable
• Connect the RF broadband input
• Test RF signal input
2.1 Receiving and Inspecting
As you unpack your unit, inspect the shipping container and equipment for
damage. Save the shipping material for future use.
If the container or the equipment is damaged, notify both the freight carrier
and Harmonic. See Appendix D, Harmonic Inc. – Offices for contact
information.
CAUTION: Before removing equipment from its antistatic bag, touch a
ground point for several seconds. A suitable ground point is an
unpainted part of the chassis of a grounded piece of equipment.
2.2 Installing the Transmitter Module
CAUTION: To protect yourself from potential injury and to protect the
equipment from further damage, do not perform any
operational tests if the equipment appears to be damaged.
The PWL 4100S transmitter module plugs into the HMC 4001 module carrier,
shown in Figure 2-1 on page 2-2. The transmitter module is held in the carrier
by a spring-loaded tab on the front handle of the carrier. You can place the
HMC 4001 carrier into any desired position in the HLP 4200 platform.
The PWL 4100S module can be plugged into the carrier either with the carrier
already mounted in the HLP 4200 platform, or prior to mounting the carrier
into the platform. The HLP 4200 platform can be powered and operational
during the plug-in process.

Figure 2-1. HMC 4001 module carrier front and rear panel features
To install the transmitter module in the HMC 4001 carrier:
• Insert the transmitter into the carrier until it locks into position.
To remove the transmitter module from the HMC 4001 carrier:
• Press down the spring-loaded tab on the carrier, then pull out the module.
To install the HMC 4001 carrier in the HLP 4200 platform:
1. Lower the HLP 4200 platform’s control/display panel.
2. Slide the HMC 4001 carrier into any available slot in the platform until it is
properly seated.
3. Lock the carrier into position with the carrier locking screw, shown in
Figure 2-1.
The PWL 4100S receives power from the HMC 4001 carrier. The carrier is
powered by the +24 VDC bus of the HLP 4200.
For additional information on the HLP 4200 platform, see the HLP 4200
Platform Product Manual. For additional information on platform controllers
and/or power supply options, see the respective Harmonic manual for each
component .
