Test / Measurement - 40G BERT

The Lowest Cost Production Test Solution

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 divided clock triggers, and excellent output eye quality. With the addition of other modular hardware, like high-power modulator drivers 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 40G clock and data demultiplexer with external clock recovery options and optional BERTs capable of measuring error rates from 5.5-11Gbps. See accessory options for other required components and cables.

Options to the SB40 include single-ended or dual-channel modulator drivers for Lithium-Niobate (LiNbO3) or Electro Absorption (EA) modulators. Customers may request additional BERTs to measure the three otherwise untested outputs from the demux. Multiple BERTs are recommended to ensure systemic errors do not occur on other channels.

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