Description The SPL 71 10-Exx transmitter is a compact plug-in module designed for use in the Harmonic HLP 4200 and 4800 equipment platform. An HMC 4001 module carrier is needed to mount the transmitter in the platform. Harmonic has optimized the SUPRALink family of transmitter modules for high-performance transmission of RF broadband information over optical fiber networks.
Page 9
Transmitter performance is optimized by combining state-of-the-art 1 550 DWDM distributed feedback (DFB) laser technology and patent pending, pre-distortion linearization circuitry. Harmonic has designed the SUPRALink family for integration into networks with advanced element management systems; each transmitter module employs a microprocessor-based communication and monitoring architecture.
Applications Figure 1-2: SPL 7110-Exx block diagram The SPL 71 10-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.

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.
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 Contacting Harmonic Support on page 31 for contact information).
2. Determine the connector type on the SPL 71 10-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 71 10-Exx, for example, SC/APC.
SPL 71 10-Exx performance. The Autosetup and Reset to Factory Settings commands are available only through this interface. For initial setup of the transmitter, Harmonic recommends using the HLP 4200 or HLP 4800 display, if available. NETWatch Site Controller Element Management System Once installed and configured, NETWatch Site Controller provides a straightforward way to monitor and control a network of multiple SPL 71 10-Exxs, either locally or remotely.
Transmitter Alarms menu. NETWatch Site Controller Harmonic’s NETWatch Site Controller provides a complete element management system, including a Windows™-based GUI and communications package for monitoring and controlling a network of multiple SPL 71 10-Exx transmitters either remotely or locally. For information on installing and using this system, consult the NETWatch Site Controller Instruction Manual.
How to set up via NETWatch Site Controller NOTE: For initial setup of the transmitter, Harmonic recommends using the HLP 4200 and HLP 4800 platform’s push buttons and display, if available. If you are using another platform (such as 4200ND) that does not have a display, the NETWatch Site Controller can be used for transmitter setup.
Factory-Optimized Settings BER (bit error rate) performance Once the Harmonic factory optimizes a SPL 71 10- Exx transmitter, the factory settings are written into the transmitter’s memory. These settings allow the transmitter to achieve the optimal performance at factory setup for any model in the SPL 71 10- Exx series of transmitters.
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.
AGC, the input level to the transmitter laser remains at its previously established value. When you use AGC mode with the SPL 71 10- Exx, 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.
Fine-Tuning the Transmitter The setup instructions described in Section 4.4.1. will normally bring the transmitter to optimal operating conditions. Harmonic recommends fine-tuning each transmitter to your specific requirements and preferences. If the factory-optimized RF level is not suitable for your particular application, you can use the following procedure to adjust the internal RF pad.
5.1.1 Cleaning Patch Cord or Pigtail Fiber Optical Connectors To clean optical connectors, Harmonic recommends using a fiber optic connector cleaning cartridge (such as NTT Cletop). If a cleaning cartridge is not available, follow these steps. 1. Fold a piece of unused dry lens cleaning paper twice, for a four-ply thickness.
SUPRALink 7110-Exx module. Under normal headend and central office environmental conditions, the transmitter can operate without fan cooling for a limited time. Should a fan failure occur, contact Harmonic’s technical service (see 6.2 In Case of Problems on page 30).
