There are two methods for mounting the ODU and the antenna: direct mounting and separate
mounting.
• The direct mounting method is generally adopted when a small- or medium-diameter and single-polarized antenna is used. In this situation, if one ODU is configured for one antenna, the ODU is directly mounted at the back of the antenna. If two ODUs are configured for one antenna, an RF signal combiner/splitter (hence referred to as a hybrid coupler) must be mounted to connect the ODUs to the antenna.
The direct mounting method can also be adopted when a small- or medium-diameter and dual-polarized antenna is used. Two ODUs are mounted onto an antenna using an orthomode transducer (OMT). The method for installing an OMT is similar to that for installing a hybrid coupler.
• The separate mounting method is adopted when a large- or medium-diameter and singleor
dual-polarized antenna is used.
1 Microwave Types
The microwave type is determined by the IF board and the configured working mode.
2 Modulation Strategy
OptiX RTN 980 supports fixed modulation and adaptive modulation.
3 RF Configuration Modes
The OptiX RTN 980 supports 1+0 non-protection configuration, N+0 non-protection configuration, 1+1 protection configuration, N+1 protection configuration, and XPIC configuration.
4 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.
5 Automatic Transmit Power Control
Automatic transmit power control (ATPC) enables the output power of the transmitter to
automatically trace the level fluctuation at the receive end within the ATPC control range. This
feature reduces the interference with neighboring systems and residual BER.

Microwave Types
The microwave type is determined by the IF board and the configured working mode.
1.SDH Microwave
The SDH microwave refers to the microwave that transmits SDH services.
Unlike conventional SDH microwave equipment, the OptiX RTN 950A has a built-in MADM.The MADM grooms services to the microwave port through cross-connections, maps the services into the STM-1-based or 2xSTM-1-based microwave frames, and then transmits the frames. With this capability, services are flexibly groomed and the optical network and the microwave network are seamlessly converged.
2. Hybrid/Packet Integrated IP Microwave
The Hybrid/Packet integrated IP microwave (Integrated IP radio for short) can transmit one type
among or a combination of Native TDM services, Native Ethernet services, and PWE3 packet
services according to software settings. Therefore, the Integrated IP radio achieves a smooth
upgrade from Hybrid microwave to Packet microwave.
