The latest introduction to the MultiLane BERT family is the ML4054B. It is a fully featured 400G BERT that directly includes an MSA compliant adapter for either QSFP-DD, OSFP or QSFP. These adapters are suitable for volume transceiver testing, since they can be replaced easily after exceeding the insertion lifetime of the connector. ML4054B simplifies production testing by eliminating the external cabling and is designed for 400G applications.

ML4054B-LP is the low-profile version and features the same hardware inside a special enclosure that mounts on the door of a MultiLane-approved temperature chamber, which is part of MultiLane’s MLT8000 thermal solutions.
