A four channel wide direct modulator driving 100G BERT

The C-BERT 2830-4 is a complete bit error rate tester dedicated for 100G Ethernet driving EMLs, VCSEL and optical modulators direct. Four independent high voltage output channels eliminate the need of external amplifiers and Bias-T circuits. The cross point alignment feature enable optimization of the optical output. The BERT eye scan reveals low-probability events and shows the true performance of the DUT to aid troubleshooting. The OS independent GUI is easy to install and enable remote control from everywhere. The compact C-BERT 2830-4 is a powerful, time saving and cost efficient solution for 100G Ethernet TOSA testing.
