Product description

The Centellax Modular 40G BER Test System is designed for device characterization, research and development testing, production testing, and general lab use. The base system tests the error rate of one in four bits of a 40Gbps true PRBS signal. The system features differential connections to the DUT, multiple low-rate synchronized clock triggers, and excellent output eye quality. With the addition of other modular hardware, like high-power modulator drivers, clock amplifiers, and additional BERTs, the system can be configured to perform a wide variety of BER and eye-mask tests at high bit rates.

The SB40 base system features a PRBS generator that can operate from 22-44Gbps, a demultiplexer, broadband divider, and a single BERT capable of measuring error rates from 5.5-11Gbps. Other required components, including cables, mechanical phase shifters, attenuators, and other parts are not included, but we can recommend the same high-quality parts we use in our labs.

Options to the SB40 include single-ended or dual-channel modulator drivers for lithium-niobate (LiNbO3) or electroabsorption (EA) modulators. Additionally, customers may request additional BERTs to measure the three otherwise untested outputs from the demux. Multiple BER testers are recommended to ensure pattern-dependent errors do not occur on other channels.

The SB40 system comes with a standard 1 year warranty on all modular components. An extended system warranty - which extends the warranty on each component an additional year - is available at any time while the system is still under warranty.
