[T10] impedance requirement (85 ohm or 100 ohm) for SAS-4

There are new cable connections in SAS-4 like SFF-8611/8612 and SFF-8654.
And I see there is a application for PCIe OCuLink with SFF-8611 cable assembly
and it's impedance is 85 ohm.
In SAS-4, the SFF-8611 cable assembly is called MiniLink and the impedance is still 100 ohm reference.
The same issue is happened with SFF-8654 cable assembly, there are two versions (85 ohm/100 ohm) in the market now.
Is there indeed two different cables for different applications (PCIe OCuLink/SAS-4) with different cable impedance (85 ohm/100 ohm)?
Or just my misunderstanding?
