Leading-edge BER testing up to 800G

Discover EXFO’s BA-4000 series of 400G/800G electrical BER testers. 

Transceivers are evolving fast and 800G is around the corner. 400G is being widely deployed in R&D environments and is finding its way to data centers and network operator field implementations.  

EXFO’s BER testing solutions are designed to deal with up to 8x56 GBd, supporting PAM4 or NRZ coding. BA-4000 is ideal for quality control and validation of the new generation of 800G transceivers, high-speed transmission line cards or module compliance boards (MCB). The easy-to-use interface allows to tune channel control, pre-emphasis and equalization for optimal signal integrity.
