Black Box LH1500 Media Converters Installation and User Guide (08/05)

100BASE-TX full-duplex twisted-pair media (100 m) [10/100 x 100% = 10%]. The total
of the two percentages (75% + 10%) is 85%, 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%.
In another instance, a Black Box Media Converter is used to connect a single
mode fiber (100BASE-FX) with a twisted pair (100BASE-T) segment. In this example,
the length of fiber Segment X is 8500m (27,880 ft). This is 57% of the maximum
allowable distance for single mode 100BASE-FX fiber full-duplex media (15,000 m)
[57/15,000 x 100% = 57%]. The length of twisted pair Segment Y is 12m (40 ft).
