The STAR-Ultra PCIe is a SpaceFibre Multi-Lane interface and link analyser, designed to aid test and development of SpaceFibre equipment. It can transmit and receive SpaceFibre traffic from a host PC at data rates in excess of 10 Gbit/s, and it can record and display SpaceFibre traffic transmitted and received on one SpaceFibre port.

The STAR-Ultra PCIe is controlled by a host PC, connected by an eight-lane Gen 3 PCIe interface, and has two quad-lane SpaceFibre interfaces. Each lane can operate at a data signalling rate of up to 7.5 Gbit/s, resulting in a maximum link speed of 30 Gbit/s.

To transmit and receive SpaceFibre traffic, our software stack named STAR-System is used. This provides high-speed drivers, applications, APIs, examples and thorough documentation.

Separate link analysis software is used to capture and display SpaceFibre traffic. When a pre-defined trigger event is detected, SpaceFibre traffic is recorded to hardware memory. Once capture is complete, the traffic is uploaded to a host PC where it is interpreted and shown in multiple software views. Each view displays traffic in different levels of detail, allowing it to be inspected at network, packet, frame and word levels.
