Put Your Multi-Rate 400GE Product to Work Now!

 

400GE is undergoing rapid development to meet the growing bandwidth requirements of ever-evolving data networks. Core networking applications are increasing  by a factor of 10 every 5 years. 400GE addresses the broad range of bandwidth requirements for key application areas such as cloud-scale data centers, Internet exchanges, co-location services, wireless infrastructure, service provider and operator networks, and video distribution infrastructure.

 

Test Tomorrow’s Technology Today

 

The Ixia K400 QSFP-DD-400GE load module will accelerate your development of IEEE P802.3bscompliant 400GE networking systems. Keysight offers  a factory and a field upgrade that provides 200/100/50GE speed capability. This provides your development teams the speeds and test options they need to create the networking technologies of the future, these load modules are available in two different models:

 

• Full feature and scale QSFP-DD-400GE

• Reduced feature and scale QSFP-DD-R400GE

 

Both models enable full line-rate traffic generation transmit, receive, and capture functionality from 64B to 16,000B frame lengths. This facilitates stress testing, hardware/ASIC bring-up, optics and cable qualification, interoperability, and functional test and Layer 2/3 routing protocol emulation as required.

 

K400 QSFP-DD-400GE: A full-featured model with 1-port, 1-slot, native QSFP-DD 400GE load module designed for enterprise and data center switch and router testing.

 

K400 QSFP-DD-R400GE: A reduced-featured model with 1-port, 1-slot, native QSFP-DD 400GE  load module designed for hardware, ASIC, cable/optics qualification, and interoperability testing.  The QSFP-DD-R400GE scales down the L2/3 feature set and L2/3 networking protocol scaling,  while increasing affordability.

 

The QSFP-DD-R400GE reduced scale and performance load module may be upgraded in the field to have the higher-capacity L2/3 feature set and L2/3 networking protocol scaling performance added through a purchasable field upgrade option. This extends the reuse of the load module and improves the ROI. This is a unique capability that Keysight offers to its customers.

 

K400 key features
