  • Page 16: Power Supply

    Overview Power Supply The SG1000 power supply (SG1-PS) is located in the housing lid to optimize heat transfer and to balance the thermal load between the base and the lid. An umbilical cord connects the SG1-PS to the housing base. A flexible power-distribution design enables you to power the node from any of the three RF ports.

  • Page 17: Network Monitoring

    Overview Network Monitoring The optional LIFELINE status monitoring system (LL-SG1) enables you to monitor the SG1000 from a headend or remote location. The LL-SG1 transponder is located in the lid, as illustrated in Figure 2-4, and is connected to the electronics package (E-pack) with an umbilical cord. The LIFELINE network monitoring system includes: LL-CU control units These units are connected to the system at the headend and interrogate each...

  • Page 21: Level Control

    2-10 Overview Level Control The gain of hybrid IC amplifiers varies with temperature. The integrated thermal control circuit senses temperature and works to offset the gain variation in the hybrid IC amplifier by signaling needed changes to the RF PIN attenuator. In addition, changes in system channel loading and/or splices in the fiber link can change the level of the received signal.

    Setup and Operation Before you begin: Test the input power using an optical power meter to ensure that expected levels are present. Refer to Section 4, “Installation,” Installing the Fiber Cables to verify that required connections have been made to the bulkhead fitting. Selecting the Gain Control Thermal control circuitry provides thermal gain control that compensates for changes in gain caused by temperature variations.

  • Page 33: Forward Path Padding

    3-10 Setup and Operation Forward Path Padding The pad values, presented in Table 3-2, serve as a starting-point reference for typical installations. These charts are prepared specifically for 77 channel systems with an upper-band edge of 750 MHz or 870 MHz. For a 110 channel system, reduce the value of the input JXP by 1.5 dB.

  • Page 34: Selecting The Wavelength

    Setup and Operation 3-11 Selecting the Wavelength You can use the SG1000 with 1310 or 1550 nm transmitters. An internal wavelength-selection jumper optimizes the optical-power test point calibration for the system wavelength. This jumper has no effect on the optical-to-RF performance (gain, flatness, slope) of the node. The wavelength jumper is factory-set and provides optimum calibration in a 1310 nm system.

  • Page 35: Optical Power Test Point

    The receiver levels measured: Are on the input side of the forward input JXP (P101). Assume the signal source is a Motorola advanced laser module (ALM) series transmitter at 1310 nm. Are typically 2 dB greater than the minimum levels listed in the table.

  • Page 43: Installation

    Section 4 Installation This section provides pre-installation instructions that enable you to prepare the node for mounting. It also provides detailed instructions for installing the node. Pre-installation Procedures To decrease weight and the possibility of damage during installation, the housing is normally mounted with the lid and E-pack removed.

  • Page 44: Installing The Node

    Installation Installing the Node Installation procedures include: Installing the housing on the strand Installing the E-pack Splicing the four-fiber service cable to the transportation fiber Installing the pin-type connectors Installing the coaxial and fiber cables Closing the housing Strand Wire Mounting Two strand clamps and bolt assemblies are located on top of the housing for normal horizontal mounting below the strand.

  • Page 45: Installing The E-Pack

    Installation To mount the housing to the strand wire: Loosen the two 5/16-18 strand clamp bolts located on top of the housing. Engage the strand in the housing strand clamps. Do not fully tighten the hex-head bolts at this time. This enables the clamps to slide along the strand wire until the housing is finally positioned with respect to the cables.

  • Page 46: Installing Pin-Type Connectors

    Installation Splice each fiber according to procedures recommended by the manufacturer of the splicing equipment. A blue-coded fiber is suggested for the forward-signal distribution and a brown-coded fiber is recommended for the return path. Cleanliness in the work area is essential.

  • Page 47: Installing The Coaxial Cables

    Installation Installing the Coaxial Cables To install the coaxial cables: Loosen the eight bolts that secure the housing lid to the base. Lower the housing lid away from the housing base. For each port, verify that the seizure screw is loosened to accept the center pin of the cable connector.
