The Data/Pattern Generators (PPGs) offer both electrical and optical outputs with standard and custom data patterns. PPG products cover data rates ranging from 100 Mb/s to 28.05 Gb/s.


4-Channel 28 Gbps Bit-Error-Rate Tester (BERT)
The OptoBERT™ OPB04X28 is the industry’s most compact, cost-effective, easy-to-use 4-channel 28Gbps electrical bit-error-ratio tester (BERT) for testing components, cables and systems in R&D and manufacturing environments. The OPB04X28 incorporates four pattern generators, four BER analyzers, internal reference clocks, and clock recovery circuits in one compact module to simultaneously test four channels at data rates up to 28.05 Gb/s. The OPB04X28 has input equalization algorithms to counteract signal degradation through input cables.

An intuitive Graphical User Interface enables easy pointand- click operation. Software drivers are available for incorporating the OptoBERT into test automation suites using programs like LabVIEW, VisualBASIC and VEE. BER test data from the OptoBERT are output directly to a spreadsheet file without any programming.
