Table 1-7. Maximum acceptable fiber cable length specifications.

Cable Type		Description
Single-mode fiber 9 µm		32,800 feet (10,000 m)
Multimode fiber 50	µm (OM3)	3280 feet (1000 m)
Multimode fiber 50	µm	1300 feet (400 m)
Multimode fiber 62.5 µm		650 feet (200 m)

NOTE: If you use single-mode SFPs with multimode fibers, you can normally double the maximum acceptable cable length.
