Discover EXFO’s BA-4000 series of 400G/800G electrical BER testers.
400G transceivers are now moving from R&D to mass production!
Bit-error-rate (BER) is the major indicator of the performance of transceivers and transmission systems. IEEE 400G standard states that forward error correction (FEC) is mandatory beyond 200G for the qualification of transceivers. Discover all the advanced FEC features available on the BA-4000.
