Table 2 Twisted Pair Cabling Specifications
" Use a straight-through cable to connect a hub or switch to a twisted
pair port on the unit. Use a crossover cable to connect a workstation to
a twisted pair port on the unit.
" Refer to Table 3 for the fiber optic cabling specifications.

With one Media Converter inline:
Switch to Switch = 372 m (1221 ft)
Workstation to Switch = 372 m (1221 ft)
Switch to Class II Repeater = 185 m (607 ft)
Switch to Class I Repeater = 137 m (450 ft)
With two Media Converters inline:
Switch to Switch = 332 m (1089 ft)
Workstation to Switch = 332 m (1089 ft)
Switch to Class II Repeater =145 m (476 ft)
Switch to Class I Repeater = 97 m (318 ft)
4. Each media converter used inline within a single collision domain will reduce the overall
segment length by 40 m (131.24 ft) of fiber.
