1.Maximum distance for 100 Mbps optical datalinks is 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.

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

External Power Supply

The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are designed with either the 12VDC or the 12-50VDC receptacle power connector.

Any of the following power sources can be used with the AT-FS238a/x or AT-FS238b/x Series Bridging converter.

❑An AC/DC power adapter - used specifically with the 12VDC-rated version model

❑An AT-PWR237 power adapter (12V or 15V output) - used with the 12-50VDC-rated version model. This power adapter must be used with the power connector provided, shown in Figure 5 on page 5.

❑A regulated power supply (SELV power source per IEC 60950) - rated minimum 12-50VDC 0.5A - used specifically with the 12-50VDC-rated version model. This power supply must be used with the power connector provided, shown in Figure 5 on page 5.

Note

Use only power sources that are UL Listed (QQGQ or EPBU), TUV Licensed, or other Safety Agencies approved, suitable for country of use.
