1 Introduction 1.1 About ADC Optical Fiber Repeater (OR) ADC optical fiber repeater provides Up-link (RVS) and Down-link (FWD) cell coverage extension. It serves as a sophisticated remote bi-directional booster, sensing and re-amplifying the RF transmission in FWD (from the base-station to the mobile users), and in RVS (from the mobile-users to the base-station), concurrently.
WiMax Optical Fiber Repeater 10W Installation and Operation Manual Overall Unique Advantages The OR product line shares unique features for exceptional coverage, low impact on the cell, high controllability, and low maintenance cost. The Remote unit is built of outdoor grade technology and a weather-proof unit, that guarantees low Noise Figure (NF), high power efficiency, unique flexibility in installation, and high reliability. 1.2 OR System Description 1.2.
WiMax Optical Fiber Repeater 10W Installation and Operation Manual System status parameters are also combined and their summary indicated by three LEDs on the repeater cabinet .
WiMax Optical Fiber Repeater 10W Installation and Operation Manual Exceptional Flexibility • Easy installation • Easy maintenance with simple access to Repeater components Automatic Level Control (ALC) for Power overload protection ALC range of more than 35dB beyond the maximum output power is included in the amplfing chains. During normal operating conditions, the repeater system should not reach the ALC level.
2 Installation Procedure NOTE: Installing an OR requires a site plan, which is a document defining the planned parameters of the cellular network. Parameters include the channel number in use, desired Repeater’s coverage area, gain settings, and antenna location. If necessary, consult your network administrator for more information. 2.1 Pre-installation Procedures 2.1.1 Receiving and Inspecting the Repeater CAUTION Verify that the packages are complete and undamaged.

WiMax Optical Fiber Repeater 10W Installation and Operation Manual The cable pinout can be found in Appendix B. It is recommended to install a small junction box containing a circuit breaker of 5A before the power cable. Installing an ELCB (Earth Leakage Circuit Breaker) is highly recommended. Connect cables as follows: a. Grounding cable. b. RF cable from the BTS c. Optical Fiber cable (Clean professionally the fiber connector) d. AC cable (Use 5A circuit breaker) Figure 2-1: Host Unit 2.
WiMax Optical Fiber Repeater 10W Installation and Operation Manual 2.6 Mount the Remote Unit 2.6.1 Precautions CAUTION The OR Remote unit is electrical equipment and should be treated accordingly. CAUTIONS 2.6.2 • Always shut down the AC or DC supply to the Remote unit before handling, replacing, or removing the unit. • The Remote unit overall weight is ~35Kg. Carry the unit carefully. • The customer is not permitted to disassemble the Remote unit. Disassembling the unit voids the warranty.
