VX160 I/O Cards
The VX160 contains two independent 160x160 fully non-blocking switch matrices. One switching matrix
connects any Upstream Port optical input (SFP+ R) to any Downstream Port optical output (SFP+ T). The
other switching matrix connects any Downstream Port optical input (SFP+ R) to any Upstream Port optical
output (SFP+ T). The VX160 Router configuration must have a minimum of 1 Upstream Card (Green) and 1
Downstream Card (Blue), each containing 20 ports. When fully configured, the VX160 will contain 8 Upstream
cards and 8 Downstream cards. The 8 Upstream cards provide a total of 160 Optical Input/Output connections
(SFP+ T/R) described as Upstream Ports 1-160. The 8 Downstream cards provide a total of 160 Optical
Input/Output connections (SFP+ T/R) described as Downstream Ports 1-160. Figure 3 depicts a bidirectional
connection from Upstream Port 1 to Downstream Port 1, showing downstream flow through one 160x160 fully
non-blocking switch matrix, and upstream flow through another 160x160 fully non-blocking switch matrix.
