Revision 2.0 System Block Diagram2-1 2.1. System Block Diagram This chapter presents FibeAir 1500 basic principles of operation. The FibeAir 1500 design concept is based on universal radio architecture. A radio link consists of two FibeAir 1500 terminals. Each terminal includes three major LRU’s, IDU, ODU and the Antenna. A single cable, carrying communications and DC power, interconnects the IDU with the ODU. Figure 2-1 presents FibeAir 1500 main blocks and modules. Figure 2-1 FibeAir 1500 System Block Diagram Chapter 2. Theory of Operation FibeAir 1500 Installation & Operation Manual 2-2In Door Unit (IDU) Revision 2.0 2.2. In Door Unit (IDU) The IDU is a compact, 17” wide, 1U-high unit, mount compatible for both ETSI and ANSI standard racks. The IDU modulates/demodulates the 155Mbps Sonet/SDH payloads, manages local and remote units, provides I/O line alarms, and provides interfaces for 1.544/2.048 Mbps Wayside channel, 64Kbps User channel and 64Kbps Order Wire channel. The IDU also interfaces a Local Maintenance Terminal or Network Management System. In addition, status alarms and indicators are provided on the front panel. The IDU major modules: n Multiplexer n Modem n Manager Card n Cable Interface n Power Supply 2.2.1. Multiplexer The Mux module functions as a Sonet/SDH Regenerator. On the line side it interfaces the OC-3/STM-1 stream, and on the radio side the Modem module. As a regenerator, the MUX either terminates or regenerates the OC-3/STM-1 RSOH. In one direction, the OC-3/STM-1 stream, interfacing through the MUX’s Rx line input terminates and the resulting stream is transmitted to the Modulator in the Modem module. In the opposite direction, the stream coming from the Modem’s Demodulator, undergoes OC-3/STM-1 Regeneration in the MUX, and transmitted through the MUX’s Tx line output. In addition, the MUX module uses the OC-3/STM-1 SOH bytes to support other services: 1.544/2.048 Mbps Wayside channel and management, 64 Kbps User Channel and Order Wire channel. The MUX module may be configured via software for transparency of most of the SOH bytes for maximum system transparency and non-intervention, at the cost of reduced functionality and services. The multiplexer module enables to integrate different interfaces and services into the SDH payload to converge Datacom and Telecom applications. FibeAir 1500 Installation & Operation ManualChapter 2. Theory of Operation Revision 2.0 In Door Unit (IDU)2-3 2.2.2. MODEM The FibeAir 1500 is equipped with a 16-states QAM Modem. The modem delivers a 155 Mb/s payload in 50/56 MHz channel bandwidth in compliance with FCC/ETSI standards. The Modem is equipped with Digital Signal Processing functions as follows: n Digital IF - I/Q modulator/demodulator whose functions are: ⇒ Conversion of the modulated signal to/from the IF frequency. ⇒ Automatic level equalization on the signal from ODU. ⇒ Protection against overloads. n Timing recovery techniques employing digital tracking loop. n FEC ensures unfaded BER lower than 10 -13 . The following figure illustrates a measured 16 QAM constellation. Figure 2-2 16 QAM Constellation Chapter 2. Theory of Operation FibeAir 1500 Installation & Operation Manual 2-4In Door Unit (IDU) Revision 2.0 2.2.3. Manager Module The Manager module controls and manages all system’s modules, local and remote units. The Manager module also supports the user interface through Ethernet or PPP/SLIP to the management station, and an ASCII terminal port. A local or dumb terminal can be used for basic configuration and performance monitoring. Other features include: n Log file. n Remote software and firmware download (upgrades can be downloaded from local to remote). n Performance monitoring. 2.2.4. Cable Interfaces A single coaxial cable connects the IDU to the ODU. This cable carries the following signals: n Transmit and receive modulated signals. n Transmit and receive control data and communications between the IDU manager and the ODU controller. n DC power from the IDU to the ODU. The system automatically issues an alarm if the cable is disconnected and provides protection against shorts. Furthermore, there is no need to measure and define the length and type of cable used since the system automatically compensates cable parameters. The following figure illustrates the signal direction through the coaxial cable. -48 VDC ODU TO IDU (CONTROL) IDU TO ODU (CONTROL) TX (PAYLOAD 155M) RX (PAYLOAD 155M) Figure 2-3 Signal Direction Through the Coaxial Cable FibeAir 1500 Installation & Operation ManualChapter 2. Theory of Operation Revision 2.0 Out Door Unit (ODU)2-5 2.2.5. Power Supplies The power supply features: n Standard Input : -48VDC n DC input range : -40.5VDC to –72VDC n DC/DC converter. n Reverse polarity protection. n Over-voltage and over-current protection. n Detection of IDU-ODU cable alarms (i.e. cable open, cable short). The ODU receives its DC power from the IDU. The PWR LED on the front panel of the IDU continuously lights to indicate the existence of input voltage. 2.3. Out Door Unit (ODU) The ODU is designed to be fastened to the antenna using four latches. The antenna is mounted on a standard mounting pole. The ODU is enclosed in a compact, weather proof enclosure and connects to the IDU via a single coaxial cable that can extend up to 300m (1000 ft). The ODU major modules: n T/R Module – A high sensitivity RF circuitry with full band frequency tuning range. n Controller – Controls the ODU and provides ODU status signals, and accurate received signal level (RSL) reading (in dBm). n Cable Combiner – Detailed in paragraph 2.2.4. n Power Supply - Detailed in paragraph 2.2.5.
