Unit specific description

The DNX R-2F/FC module is designed to enhance the performance of the network by
monitoring and optimizing the performance of the physical transmission layer. Each of
the inter-node links (links between the DNX R-2F/FC nodes) are managed
independently from each other. This allows for each link to have different
characteristics. The performance of each link is monitored to track and record its
associated Quality of Service (QoS).

The cable performance for the data rate of transmitted signal will vary according to the
type and length of cable used. Although each link in the transmission path will be
optimized for performance, the maximum data rate will be limited to the poorest
performing link in the network. Figure 8 illustrates the independent links in a typical
class A DNX R-2F/FC application.
