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 MCP7H60 cable is QSFP-DD. Hence the memory map of its EEPROM is formatted in compliance with CMIS 4.0 ‎[1]. The key parameters are listed below. The EEPROMs of the QSFP ‘tails’ are SFF-8636 ‎[4] compliant. The memory map of the QSFPs is found in the "QSFP28 Memory Map – SFF-8636 compliant - I2C Address A0h" table further down.

Length

Length in multiples of the base length, which can be 0.1, 1, 10 or 100 [m], as set in bits 7-6. The multiple is set in bits 5-0.

Bits 7:6 (Base):
00 – base is 0.1m
01 – base is 1m
10 – base is 10m
11 – base is 100m

Examples:
41h: 1m (01000001 -> 1m * 1)
15h: 1.5m (00001111 -> 0.1m * 15)

According to SFF-8636 section 7.3.12 Length:
“For modules with non-separable media interfaces, this field specifies the link length of the cable assembly (copper) in units of 1 meter. Link length is as specified in the INF-8074 specification. Link lengths less than 1 meter shall indicate 1 meter.”
