VX320 I/O Cards
The VX320 Router configuration can have a minimum of one I/O Card in either the Upper Card Cage or the
Lower Card Cage. The VX320 Router is constructed with one fully non-blocking 320x320 switch matrix in the
Upper Card Cage and another fully non-blocking 320x320 switch matrix in the Lower Card Cage. Each VX320
I/O card contains 16 ports, so that when fully configured, the VX320 will contain 20 I/O cards in the Upper Card
Cage and 20 I/O cards in the Lower Card Cage. The 20 I/O cards in the Upper Card Cage provide a total of
320 Optical Input/Output connections (SFP+ T/R) described as Upper Card Cage Ports 1-320.
Similarly, the 20 I/O cards in the Lower Card Cage provide a total of 320 Optical Input/Output connections
(SFP+ T/R) described as Lower Card Cage Ports 1-320. The Upper Card Cage switching matrix connects any
Upper Card Cage Port optical input (SFP+ R) to any Upper Card Cage Port optical output (SFP+ T), even if it
is the same Port number (i.e. Port 1 R connected to Port 1 T). Similarly, the Lower Card Cage switching matrix
connects any Lower Card Cage Port optical input (SFP+ R) to any Lower Card Cage Port optical output (SFP+
T), even if it is the same Port number (i.e. Port 1 R connected to Port 1 T).
Figure 4 depicts a bidirectional connection. One direction is the connection from the Upper Card Cage Port
optical input (SFP+ R) to the Upper Card Cage Port optical output (SFP+ T), showing Video/Data flow from the
TX to the RX being routed through the Upper Card Cage 320x320 fully non-blocking switch matrix. The other
direction is the connection from the Lower Card Cage Port optical input (SFP+ R) to the Lower Card Cage Port
optical output (SFP+ T), showing the Data (KMASS) flow from the RX to the TX being routed through the
Lower Card Cage 320x320 fully non-blocking switch matrix.
