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:
- Full feature and scale CFP8-400GE
- Reduced feature and scale CFP8-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.
Key Features
The key features of K400 CFP8 load module are as follows:
- Supports line-rate 400Gbps packet generation, capture, and analysis of received traffic to detect and debug data transmission errors.
- Supports line-rate per-port and per-flow statistics.
- Provides high latency measurement resolution at 0.625ns.
- Provides RS-544 (KP4) Forward Error Correction (FEC) support.
- Provides native 28Gb/s SERDES with NRZ encoding support that is IEEE 802.3bs compliant.
- Supports FEC error injection with a comprehensive set of FEC corrected and uncorrected statistics, including Bit Error Rate statistics for pre- and post-FEC operations.
- Injects packet errors: CRCs, runts, giants, checksum errors, and out of sequence.
- Supports standard Ixia instrumentation including timestamp, sequence number and flow identification, and data integrity.
- Supports layer 1 BERT: 16 independent lanes of 28Gb/s PRBS pattern generation, error checking, and statistics.
- Supports 400G PCS lanes Transmit, error injection testing and receive measurement:
- Per-lane controls and status, FEC and error monitoring, error insertion, lane mapping and skew insertion
- Supports mid-to-high-range L2/3 networking protocol emulation to validate performance and scalability of L2/3 routing/switching and data center test cases using the Ixia’s IxNetwork application.
- Provides an excellent test platform for full line-rate 400Gb/s to evaluate the new 400GE ASIC designs, FPGAs, and hardware switch fabrics that use the new 16x28Gb/s electrical interface with NRZ encoding.
- Supports benchmarking of networking devices and equipment using industry-standard RFC benchmark tests at line-rate 400GE.
- Provides application support including: IxExplorer, IxNetwork, and related Tcl and automation APIs.
