This product is compatible with ESD levels in typical data center operating environments and certified in accordance with the standards listed in the Regulatory Compliance Section. The product is shipped with protective caps on all connectors to protect it during shipping. In normal handling and operation of high-speed cables and optical transceivers, ESD is of concern during insertion into the QSFP cage of the server/switch. Hence, standard ESD handling precautions must be observed. These include use of grounded wrist/shoe straps and ESD floor wherever a cable/transceiver is extracted/inserted. Electrostatic discharges to the exterior of the host equipment chassis after installation are subject to system level ESD requirements.

The head-end of the MCP7H50 cable is QSFP-DD. Hence the memory map of its EEPROM is formatted in compliance with CMIS 4.0. The key parameters are listed below. The EEPROMs of the QSFP ‘tails’ are SFF-8636 compliant. The memory map of the QSFPs is found in the QSFP56 Memory Map – SFF-8636 compliant - I2C Address A0h table .
