Here’s a summary of the biggest features:
For our Z800 Freya customers:
- Support for using ANLT at 56Gbps PAM4 SerDes when testing 400, 200 and 100Gbps (in addition to 112G SerDes)
- Z800 Freya QSFP112 cage now supports running 1x400G, 2x200G and 4x100G
- A new FEC Error Injection feature makes it easy to configure any kind of FEC Error inject
- PCS Tx Lane Swap feature makes it test and verify proper lane alignment
XenaManager now lists all available CMIS (Common Management Interface Specification) registers and names.
Z400 Thor now also supports 8 x 10G or 8 x 25G within a single QSFP-DD cage.
RELEASE 98 IN DETAIL:
Up until now, the ANLT capabilities of the Z800 Freya traffic generators could only be used when running 112G SerDes traffic. Now, with Release 98, this has been expanded so Freya also supports 56G SerDes when testing 400GE, 200G and 100G.
Z800q Freya has two physical cages and the QSFP112 cage now supports running 1x400G, 2x200G and 4x100G. This means, for example, that when testing RFC 2544 you can use both Freya ports simultaneously to run 400GE.
Forward Error Correction (FEC) is used to detect and correct a certain number of errors in a bitstream by appending redundant bits and error-checking code to the message block before transmission. FEC is a mandatory part of 56G and 112G SerDes and defined as part of the IEEE 802.3 standard. To verify the FEC, XenaManager now provides the capability to inject FEC symbol errors. This is done via a new UI in XenaManager that makes it easy to configure any kind of FEC Error inject, including the number of error symbols, the position of the errors in the Codewords and if the error symbols should stay static, rotate or be incremented.
Ethernet allows physical lanes to be swapped, and the protocol must ensure correct lane alignment. The Z800 Freya’s PCS Tx Lane Swap and skew feature is designed to test and verify proper lane alignment on the Device Under Test (DUT) and to verify the robustness of the implementation. XenaManager and Freya offer the capability to randomly swap lanes and verify compliance, as well as insert various skews to determine alignment lock limits. This functionality ensures comprehensive testing and validation of the Device Under Test (DUT), confirming its robustness and adherence to standards.
The Common Management Interface Specification – or CMIS as it’s called – is valuable for knowing what kind of media is in a network port and what capabilities it offers. In Release 98, XenaManager now lists all available CMIS registers and their names from versions 3.0 up to 5.2. XenaManager provides an overview of register names, access rights for the registers, register values and where in memory the data are stored. It is possible to both read and write registers and save the information to a file.
The Z400 Thor traffic generator is a best-seller among customers thanks to it being able to test seven speeds from 10G to 400G. In Release 98, we’ve enhanced its 10G and 25G capabilities by enabling the Z400 Thor to support 8 x 10G or 8 x 25G within a single QSFP-DD cage.
XenaManager introduces a new Virtual Lane Group overview that dynamically updates based on user-changed FEC modes. This feature offers comprehensive insight into port Tx Lane Configurations and Rx Lane Status, providing a complete overview of SerDes and lane mapping, as well as signal quality per lane—all in one convenient location.
Finally, to minimize confusion, all the new Teledyne product names can now be seen in Release 98 of XenaManager by looking at the Identification fields under the Module Properties section of the Main Module Config tab.
