Bit Error Rate Tester (BERT)

Bit Error Rate Tester (BERT) for OC-768, 100GbE, 400G

SHF Bit Pattern Generators (BPG), Pulse Pattern Generators (PPG) and Error Analyzers (EA) form a future-proof bit error rate tester (BERT) which supports 100 Gigabit Ethernet developments based on multiple 28/32 Gbps and 56/64 Gbps channels for 40/43 Gbps (OC-768), 28 Gbps CEI, Infiniband, Fiber channels as well as parallel channel data-com. The SHF 12104 A, SHF 12105 A and SHF 11104 A are worldwide the first BPG and EA instruments delivering a speed of more than 64 Gbps per channel!

Going even further (100 Gbps serial and 60 GBaud arbitrary waveform generation)

Our BPGs operate hand in hand with our high speed digital modules (so called extender heads). Expanding the BERT with a SHF 603 A Multiplexer and SHF 623 A Demultiplexer raises the serial data rate to ≥ 120 Gbps. A PAM4 or PAM8 source is formed by attaching one of our DAC modules. The programming capabilities together with the channel synchronization render the BPG + DAC combination to be a full “remote head” AWG (Arbitrary Waveform Generator) at a speed of up to 60 GSymbols/s. A PAM4 Bit Error Ratio (BER) measurement solution up to 58 GBaud is formed by extending the SHF 11104 A EA with our SHF 11220 A PAM4 Sampler.
