Product Model: QSFP28 host board V1.30 PCB Marking: E206460 PCB Number: AL-85MA-0
QSFP28 Host Board V1.30 is a high-speed host-side evaluation/test PCB for 100G QSFP28 optical transceivers. The board routes the QSFP28 electrical interface to an arc array of gold SMA coaxial connectors around the top edge and to a QSFP28 cage/connector at the bottom center, enabling signal-integrity, compliance and interoperability testing of QSFP28 modules on the host side. PCB markings include E206460, AL-85MA-0 and the revision label "QSFP28 host board V1.30".
