Chapt er 3. Installation Procedure This following installation procedure is based on the assumption that site survey and installation planning (including power requirements) have been completed: • Infrastructure preparation according to site analysis and planning: Fiber Optic, coax cable and DC cable installation, Splice the fiber optic cable according to the fiber optic infrastructure design plan.
MobileAccess™ 1000/1200 3.1 Installation Procedure General There are two types of installations: single-building and multi-building (campus) configuration. This section describes the recommended Fiber Optics and system location for both configurations. It is recommend to perform the following steps for all MobileAccess installations (both single- and multi-building). Single-building Installation In this installation, all Base Units are placed in the same location (usually in the communication room).

MobileAccess™ 1000/1200 Installation Procedure Example 2: Horizontal Structure In a horizontal layout installation, a separate fiber optic cable is connected to every site location, where a site may include more than one RHU. The connection may be to a splice box or directly to the RHU (depending on the site confiugraiton).
Installation Procedure 3.2 MobileAccess™ 1000/1200 About Infrastructure Installation Note: When working with fiber optics, it is crucial to maintain a clean working environment. However, if the working environment has been tainted or if the optics connectors has not been covered, refer to appendix x for information on cleaning the fiber optic cable. ATTENTION: MobileAccess™ requires singlemode fibers with SC/APC connectors. Be sure to use only these types of fibers.
MobileAccess™ 1000/1200 3.3 Installation Procedure Power Supply for the MobileAccess™ Note: Power to the MobileAccess™ modules may be supplied by any configuration of power supplies that provide the necessary voltage and power. It is recommended to calculate the required power according to the requirements of the specific installation and then determine the configuration of the power supplies. The required DC cables will then be determined by the selected PS configuration.

Chapt er 4 . Adjustments Procedure This procedure is used to adjust the system to provide optimal performance. The system will be operational without this adjustment procedure; however, the system performance will be better. Adjustments can be made only after the system is fully installed. The adjustments procedures differ depending on the system topology: • With RIU • Without RIU • Main building adjustments • Remote building adjustments The adjustment procedure consists of three phases: 1.

Verify that the MobileAccess RS232 slide-in panel is inserted in the MobileAccess 410/430 controller and connect the laptop to on which the MCT application is installed to the RS232 front panel connector. 3. Launch the MCT application, double-click on the first BTSC element (i.e. BTSC 1) in the Topology tree, and access the Adjustments pane. 4. Select the type of adjustment (Live or Emulated signal source) and click Adjust.
Appendix A. Frequently Asked Questions 1. What are the BU and the RHU, and for what are they used for? The MobileAccess™ system consists of two modules: Base Unit and Remote Hub Unit. The Base Unit interfaces between the microcell or base station and the Remote Hub Unit (RHU). The interface is via either a composite cable or fiber optic cable.
Adjustments Procedure MobileAccess™ 1000/1200 12. What is the RF input power required at the Base Unit? The required composite RF input power at the Base Unit is between 0dBm to 7dBm, depending on the operating standard. 13. What alarms are in the system, and how can they be transmitted to a central monitoring system? The MobileAccess™ system can support 3 alarm options: Dry Contact alarms (Normally Closed), Dry Contact alarms (Normally Open) and open collector alarms.
: Link Measurements Appendix B. Form To smoothly carry out link measurements, refer to table Table 4-2: Fiber optic Cable Test Results. This table aids system evaluation and provides necessary feedback to MobileAccess. The following issues should be taken into account: • Measure the optical power for every link with an optical meter and light source, according to the number of links or RHU’s. • Measure the typical signal strength (RSSI) for every installed antenna.

NOTE: In order to explain the testing procedures, the terms related to these tests need to be explained.
MobileAccess™ 1000/1200 Adjustments Procedure Fiber Optic Cable – Appendix D. Terms Fiber optic cable is produced in a variety of formats with different characteristics.
Adjustments Procedure • Jacket. glass. MobileAccess™ 1000/1200 The jacket covers the buffer, providing greater protection to the The fiber consists of Core and Clad. The central part of a fiber is known as the core, and the material surrounding the core is known as the clad. The clad has a lower index of refraction than the core, allowing light to be completely reflected off the surface between the core and the clad. As a result, propagated light remains entirely within the core.
MobileAccess™ 1000/1200 Adjustments Procedure Connecting Fiber Optic Cable In order to carry out a fiber optic connection a Splice and a Connector are required. • Splice. A splice consists of cutting the fiber optic cable across the cable’s diameter and combining the opening with another fiber optic cable. A splice can be carried out in the following methods: • Fusion – following the splice, the cables are warmed and the two fiber optic cables are melted together.
Optical Test Procedure Appendix E. This section describes the methods applied to test fiber optic cable’s optical insertion loss and return loss. Fiber Optic Cable Test Due to the extended distances that analog signal transmissions travel on cable, the major challenge is to determine the status of the cable. In order to determine that the cables are functioning, technical personnel need to perform optical power tests.
MobileAccess™ 1000/1200 Adjustments Procedure Test Equipment In order to perform these tests, the following equipment is necessary: • Light source (for wavelength 1310nm , 0dbm) • Optical power meter • Optical coupler (hosed and connectorized) • Fiber optic jumper • Adapter parts for the cable connectors For information about equipment suppliers, contact MobileAccess. Optical Insertion Loss Measurement Test The optical insertion loss measurement tests the attenuation of the cable.
Adjustments Procedure MobileAccess™ 1000/1200 Method #2: Single Point Test Connection description: This method assumes that there are two parallel fibers on the path to be tested. Connect fiber jumper at end of the cable being tested to another parallel cable. Connect the light source, optical power meter and optical jumper as shown in Figure 4-5. This measurement can test two cables simultaneously. Fiber optic jumper Light source Optical power meter Connector Figure 4-5: Single Point Test 1. 2. 3.
MobileAccess™ 1000/1200 Adjustments Procedure Optical Return Loss Measurement Test Connection description: Connect a light source and optical power to the inputs. If the coupler has one output, connect the tested cable to this output. If the coupler has two outputs make a pigtail at the second output.
Adjustments Procedure MobileAccess™ 1000/1200 Make pigtail. If cable is shorter than 100 meter, then verify that cable is disconnected at end. Measure the return light power (P2), connector #2. Calculating Return Loss Calculate the difference between the signals in dB. (Return loss)dB = (P2)dBm – (P3)dBm + (Lc)dB Results The following table is to be filled in by technical personnel testing the fiber optic cables.
