Huawei OptiX RTN 950 (sharing knowladge).pdf OptiX RTN 605 Radio Transmission System V100R005C00 Configuration Guide Huawei OptiX RTN 950 Commissioning and Configuration Guide(V100R003). The OptiX RTN 905 adopts a split structure. The system consists of the IDU 905 and the ODU. Each ODU is connected to the IDU 905 through an IF cable. Features of the IDU 905 Item Description Type IDU 905 1A IDU 905 2A IDU 905 1C Chassis height 1U Extended sub card Not supported An extended sub-slot is reserved. Signal Processing in the Transmit Direction The multiplexer splits the signal from the IF cable into a 350 MHz IF signal, a 5.5 MHz O&M uplink signal, and a -48 V DC power signal. In the transmit direction, the IF signal is processed as follows: • After the up-conversion, filtering, and amplification are completed, the IF signal is converted into the RF signal and then is sent to the AMP amplifier unit. • The AMP amplifies the RF signal (the output power of the signal can be controlled by the IDU software).

The O&M uplink signal is a 5.5 MHz ASK-modulated signal and is demodulated in the CTRL control unit. The -48 V DC power signal is sent to the PWR power unit where the secondary power supply that uses a different voltage is generated and provided to the modules of the ODU. Signal Processing in the Receive Direction The duplexer separates the RF signal from the antenna signal. The RF signal is amplified in the low noise amplifier (LNA). After the down-conversion, filtering, and amplification are completed, the RF signal is converted into the 140 MHz IF signal and then is sent to the multiplexer. The O&M downlink signal is modulated under the ASK scheme in the CTRL unit. The 10 MHz signal is generated through the modulation and is sent to the multiplexer. The CTRL unit also detects the received signal power through the RSSI detection circuit and provides the RSSI interface. The IF signal and the O&M downlink signal are combined in the multiplexer and then are sent to the IDU through the IF cable. Functions and Features. Amx netlinx studio manual. The OptiX RTN 905 provides a wide assortment of functions and features to ensure the quality and efficiency of service transmission. • Microwave Types The OptiX RTN 905 1A/2A supports Integrated IP radio microwave, and the OptiX RTN 905 1C supports Integrated IP radio microwave and SDH microwave. • Modulation Strategy OptiX RTN 905 supports fixed modulation and adaptive modulation. • RF Configuration Modes The OptiX RTN 905 supports multiple RF configuration modes. • Capacity The OptiX RTN 905 is a high-capacity device. • Interfaces The OptiX RTN 905 provides a variety of interfaces. • Cross-Polarization Interference Cancellation Cross-polarization interference cancellation (XPIC) technology is used together with co-channel dual-polarization (CCDP). The application of the two technologies doubles the wireless link capacity over the same channel. The OptiX RTN 905 2A supports XPIC function. The OptiX RTN 905 1C supports XPIC function by means of NE cascading.
