Length

Length in units of 1 m of direct attach copper cable.
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 or AOC) 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.”

Length 0.1m

Total cable length is the sum of byte 18 for number of meters and byte 108 for 0.1m.

Values:
00h: 0m

09h: 0.9m

Examples:
2.5m: Byte 18 = 02h, Byte 108 = 05h
2.25m: Byte 18 = 02h, Byte 108 = 03h

AWG

DAC cable AWG information.
18h: AWG=24
19h: AWG=25
1Ah: AWG=26
1Ch: AWG=28
1Eh: AWG=30
20h: AWG=32

Please note that the MCP2M00 is a passive cable, and therefore has no Digital Diagnostic Monitoring (DDM) functions implemented. However, it is considered compliant with SFF-8472 to enable the host system to read device declarations including interconnect type, link code, and cable length. The compliance and DDM declarations are interpreted as follows:

Read address 94 = 08h. This declares SFF-8472 rev. 12.3 compliance.

Read address 92 bit 6 = 0. This declares that DDM is NOT implemented. This declaration contradicts the wording of SFF-8472 rev. 12.3, but it prevents the host system from hanging if attempting to access the unimplemented upper page A2h.
