*Worst case delays taken from IEEE Std 802.3u-1995, actual delays may be less for a particular cable.
Contact your cable supplier for exact cable specifications.
Each shared Fast Ethernet network device also has an associated BT delay. Table
3.4b shows typical Fast Ethernet device components and the associated BT delay. Note that
there is only one DTE pair associated with any device-to-device path.
