A Distance Calculation Example:
Connectivity between ThinNet and TP Ethernet Media.
In the figure shown above, the length of Segment X is 72m (216 ft). This is
39% of the maximum allowable distance for 10BASE2 media (185 m) [72/185 x 100% =
39%]. The length of Segment Y is 55m (165 ft). This is 55% of the maximum allowable
distance for UTP 10BASE-T media (100 m) [55/100 x 100% = 55%]. The total of the
two percentages (39% + 55%) is 94%, which is allowable.
Note 1
: Where more than one media converter is used in one
segment run, the percentages for all of the cabling lengths in the run
must be added together and must not exceed 100%.
Note 2
: If the total segment distance calculation result is greater than
100%, consider using a Repeater so that each cable type can be 100%
of its maximum allowed length.
Note 3
: The maximum number of 10 Mbps Media Converters that
can be used in series is two. The cumulative noise from three or
more units together causes packet alignment errors, dropped packets.
