Trunk Line and Drop Line Length

Refer to the ODVA website (www.odva.org) for more information on network cabling.
◆

Trunk Line

The maximum allowable trunk line length depends on the type of cable used and the
network baud rate. The total cable length includes the length of the trunk and the sum of
all the drop lines.
Baud Rate (kbps)
125
250
500
To calculate the maximum total length for trunk lines of mixed thick and thin cables, use
the following formulas:
• 125 kbps: L
+ (5 x L
thick
• 250 kbps: L
+ (2.5 x L
thick
• 500 kbps: L
