RFU-C Overview

RFU-C is a state-of-the-art Radio Frequency Unit which is fully software configurable and supports a broad range of capacities and interfaces.

The RFU supports low to high capacities for traditional voice and Ethernet services, as well as PDH/SDH/SONET or hybrid Ethernet and TDM interfaces.

This innovative platform uses an ``on-the-fly'' upgrade method, whereby network operators only buy capacity as needed, benefiting from savings on initial investments and OPEX.

Traffic capacity throughput and spectral efficiency are optimized with the desired channel bandwidth. For maximum user choice flexibility, channel bandwidths can be selected together with a range of modulations from QPSK to 2048 QAM.

High spectral efficiency is ensured using the same bandwidth for double the capacity, via two carriers, with vertical and horizontal polarizations. This feature is implemented by a built-in XPIC mechanism.

For Ethernet and TDM to Ethernet migration, RFU-C works with the PTP 820G IDU.

When RFU-C operates in co-channel dual polarization (CCDP) mode, using the cross polarization interference canceller (XPIC) algorithm, two carrier signals can be transmitted over a single channel, using vertical and horizontal polarization. This enables double capacity in the same spectrum bandwidth.
