Product Overview

The ML4054B is a fully featured 400G BERT with an integrated module interface, ideal for product development and validation, plug-and-play characterization and production testing of QSFP-DD, OSFP, and QSFP transceivers. This instrument facilitates production testing and volume testing, and is equipped with a field-replaceable, MSA-compliant adapter.

The platform is available as a benchtop and low profile version, to enable versatile thermal testing use cases. The low-profile version can be directly mounted on the door of a MultiLane-approved temperature chamber. In addition, full CMIS control and compliance testing is enabled in this versatile BERT.

The GUI allows you to individually control each TX level, equalization, eye balance, pattern, coding, and inject error sequences into the stream. The receiver features CTLE and FFE equalization for up to 14 dB of loss at Nyquist; it also allows advanced troubleshooting capabilities.
