1.6Tbps (224G SerDes) traffic generator
Z1608 Edun is one of the world’s first Ethernet traffic generators for testing 224G PAM4 SerDes.
The Z1608 Edun comes with the OSFP-1600 interface and can be used with both optical cables, as well as active and passive cables.
The Z1608 Edun can be used for testing next-gen chips, Ethernet switches, routers, NICs, transceivers & cables helping developers optimize signal integrity and Bit Error Rate (BER) performance.
Providing the same UI and features as the existing Xena solutions (e.g. Z800 Freya), the Z1608 Edun boasts an extensive list of valuable features and functions for both advanced Layer 1 & Layer 2 testing. The extensive L1 features includes valuable insights into advanced PCS and PMA layer testing including dynamic transceiver clock sweep, lane skewing and PRBS modes.
There is also an advanced Signal Integrity View (SIV) to provide visual information on signal quality. The Layer 1 features can be combined with an enhanced Traffic Generator with advanced multi-stream support and functionalities such as latency and jitter statistics, modifiers, custom data fields and many other features.
The Z1608 Edun is a 1U chassis solution, making it the most compact and lightweight 224G tester in the market.
Advanced test software
Managing the Z1608 Edun is done using XenaManager, the intuitive multi-user management software for generating and analyzing traffic on all Teledyne LeCroy Xena modules.
Renowned for its ease-of-use, XenaManager makes it quick and easy to do performance, QA, functional and benchmark testing.
Xena OpenAutomation (XOA) – our open-source scripting and automation framework – is also included to help automate any available command to the system, with tailored tests, scripting and standardized test methodologies.
Plus there are standalone applications for testing RFC2544, RFC2889, RFC3918 and RFC1564.
“XIO” interface
Teledyne Lecroy’s Z1608 Edun provides a special “XIO” interface implemented using a USB-C connector with a proprietary pinout.
This connector allows external equipment full control of the complete management interface of the OSFP module inserted into the Z1608. All digital electrical signals of the OSFP connector are accessible, including the I2C management interface as well as the reset, module present and select, Low Power mode and interrupt.
The Z1608 is also able to adjust the voltage level of the 3.3V power supply to the OSFP module, and can measure the power consumption for the module as well as the temperature of the surroundings. Combining this with the flexibility of the XIO interface, facilitates extensive debugging and characterization of all aspects of the OSFP module, effectively eliminating the need for an external Module Compliance Board (MCB).
The pinout of the XIO USB-C connector is shown below. It has been designed to be symmetrical so an external cable cannot be inserted incorrectly, as is the case with the normal USB-C connector.

Xena uses high-quality 224Gbps-capable electrical OSFP connectors on Z1608 Edun modules for optimal signal integrity and performance. However, all connectors experience wear when inserted, resulting in decreased signal integrity over time.
The OSFP Connectors provides a minimum of 1000 cycles where optimal signal integrity is guaranteed.
