IXIA K400 CFP8 Load Modules

This chapter provides details about K400 CFP8 family of load modules and their specifications and features.

K400 CFP8 is a 1-port, 400GE load module. It provides FEC error injection, PCS/Tx/Rx testing, and layer1 BERT testing with full line-rate layer 2-3 Tx, Rx, and capture capabilities. This load module accelerates development of IEEE 802.3bs-compliant 400GE networking systems.

These load modules are available in two different models:

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.
