Fast and effective 100 Gbit Ethernet optical transmitter (TOSA) testing

The C-BERT 2840-4 is a new kind of bit error rate tester for 100G Ethernet optical transmitters and TOSA. The new test instrument has four built-in optical to electrical receivers to provide an optical reference receiver functionality in the BERT. The optical receivers have 4th order Bessel-Thomson characteristics to perform a compliance eye mask tests with the fast BERT eye scan mode of the C-BERT. In addition the OMA and the extinction ration are extracted from the four BERT eye scan diagrams and the detector current. The vertical eye width and eye height are measured at a given bit error rate is as well. The C-BERT 2840-4 combines four pattern generators, optical reference receivers and eye mask testers in one compact instrument to eliminate expensive sampling oscilloscopes and to implement a fast and cost efficient transmitter test solution in production and lab.
