LASER COMPONENTS offers the BERT-1102 from Quantifi Photonics, a PXI-based 29G PAM4 BERT which offers 8 lanes of 29Gbaud PAM4 in a single PXI module. It has the ability to scale to 64 channels in a single PXI chassis and up to 512 channels by chaining 8 chassis together. With a built-in distributed clock, the PAM4 BERT reduces cabling and maintains a small, streamlined footprint.

Built on open, modular, proven PXI technology, the PAM4 BERT is used alongside a module compliance board, oscilloscope, and intuitive software. The single platform transceiver test solution reduces complexity.
