The C-BERT 2850-4 is an innovative bit error rate tester which solves accuracy issues in testing 100G Ethernet multi-lane optical receiver. To achieve repeatable and confident test results four long-term stable optical transmitters with uniform output performance are integrated in the 2850-4. The four Mach-Zehnder Modulators are driven direct from the internal pattern generators and are stabilized by advanced control circuits without output signal degradations. As a result of this unique architecture the 2850-4 produces high quality and long-term stable signals for improved measurement accuracy.
The innovative C-BERT 2850-4 is a very powerful, time saving and cost efficient solution for 100G Ethernet multi-lane optical receiver and ROSA testing.
