This table shown here provides some general guidelines for the tolerable off-state capacitance values for the line side of Ethernet and for the PHY side. These are nominal values, the specific values tolerated by a specific design may be different due to board layout considerations, ambient noise levels, length of cabling, and type of cabling (CAT5, CAT5e, CAT6 or CAT7). Rate and reach testing is needed to prove specific level of tolerance to off-state capacitance values.
