The OptiX RTN 900 product series can use the RTN 600 ODU and RTN XMC ODU, covering the entire frequency band from 6 GHz to 42 GHz.
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. Figure illustrates the direct mounting method.
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. Figure shows the separate mounting method. In this situation, a hybrid coupler can be mounted (two ODUs share one feed boom).
The OptiX RTN 950 provides an antenna solution that covers the entire frequency band, and supports single-polarized antennas and dual-polarized antennas with diameters of 0.3 m to 3.7 m along with the corresponding feeder system.
