MultiLane's ML4054B 400G BERT has a field-replaceable QSFP-DD MSA-compliant high-speed adapter interface for lowered cost of connectivity and is ideally suited to test 400G transceivers in manufacturing. This is complemented by an innovative cabled connection scheme, enabling superb signal integrity and low BER floor, says the company.

Judge’s comment: “Testing 400G QSFP-DD and OSFP modules accurately in manufacturing at a fraction of the cost of high-end BERT equipment will be attractive to many transceiver manufacturers."
