BA-4000-L2 - BER tester with real traffic

Overview
Combined L1 BER tester and L2 traffic analyzer for 800G DR4/FR4/LR4 and 800G LPO transceivers
BA-4000-L2 - BER tester with real traffic

Key features

  • Superior hardware design: native electrical interface, excellent signal quality, clean eye diagram and low error floor
  • Layer 2 framed testing: delivers a real system view for L1 device under test (DUT) from L2 framed traffic
  • Layer 1 BERT: excellent signal quality alongside layer 2 testing
  • Real-time FEC analysis: testing of pre/post FEC BER, symbol error distribution and FEC margin
  • Powerful equalizer and channel simulator: powerful equalizer includes CTLE, 32 taps FFE and DFE. Ideal for LPO transceivers
  • Layer 2 testing: tests 800G DR4/FR4/LR4/ZR with framed L2 traffic
