Table 1 lists the operating distances for the AT-FS21x and AT-FS212/x Series
Switches.

1. Maximum distance can only be obtained when the UTP/STP cabling is installed and verified to the TIA/EIA 568A
Commercial Building Telecommunications Cabling Standard.

2. Maximum distance for 100 Mbps Optical Datalinks are dependent on the following factors: type of optical fiber,
duplex mode of both end-nodes, and maximum optical loss budget for each of the optical fiber at the operating
optical wavelength.
