NTA4100
400G Network Tester
Semight NTA4100 is specifically designed for high speed ethernet traffic test, which supports not just 400GE, but also other speeds as 200GE and 100GE. It can be used to handle comprehensive KP4 forward error correction (FEC) testing and statistics, FEC symbol error injection testing, L1 BERT and the L2 performance testing.
- High Bandwidth – High bandwidth, high throughput, support rate up to 400Gbps
- Standards compliant – 400G FEC function implementation fully compliant with Ethernet protocol
- Full Ethernet Analysis Capabilities – Provides 400G Ethernet, MAC/PCS/PMA/PMD layer analysis functions to efficiently diagnose product problems
- Support module protocol – Support CMIS 4.0, provide loopback test function, Support module MDIO read and write
