Table 3.2.2a: Worst case round-trip delay for Fast Ethernet media*

 

Media Type

Round-trip delay in Bit Time per Meter (BT/m)

 

 

Fiber Optic

 

1.000

 

 

Shielded TP cable

 

1.112

 

 

Category 5 Cable

 

1.112

 

 

Category 4 Cable

 

1.140

 

*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.
