  • Page 5: Chapter 1 Overview

    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.
  • Page 6 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.
  • Page 7 Figure 1-2. PWL 4100S block diagram 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...

    8.5 dB. Fine-Tuning Each Transmitter Harmonic recommends fine-tuning each transmitter to fit your specific requirements and preferences precisely. You can modify the transmitter configuration to trade off CNR performance for improved CSO and CTB distortion performance.

  • Page 22: Autosetup, Automatic Gain Control, And Manual Gain Control

    Gain Control The Autosetup feature enables you to quickly set the internal drive level to the laser as close as possible to the optimal value determined at the Harmonic factory. The transmitter operates in either the Automatic Gain Control (AGC) mode or the Manual Gain Control (MGC) mode.
  • Page 23 Figure 4-2. RF drive level as a function of channel loading Even if you plan to add more video channels in the future, Harmonic recommends that you use 15 dBmV per channel to ensure that the system is easy to upgrade.

  • Page 24: Automatic Gain Control And Manual Gain Control

    When you select AGC, the input level to the transmitter laser remains at its previously established value. When you use AGC mode with the PWL 4100S, Harmonic recommends that you drive the transmitters 3 dB harder so that they can better compensate for the increased variation in the RF input signal.
