AT-B17 (100Base-FX) Expansion Module
If an AT-B17 Expansion Module is present, its fiber ports may be used for
backbone and longer distance connections.
This expansion module requires 50/125 or 62.5/125 micron multimode
fiber optic cabling with an SC connector at both ends. For SC fiber ports,
connect one end of the cable to the SC connector on the expansion
module and the other end to the SC connector on the other device.
Since SC connectors are keyed, the cable can be attached in only one
manner. If you use an SC/ST converter with ST fiber ports, be sure to
connect the Tx (Rx) connector on the slide-in module to the Rx (Tx)
connector on the other device.
The fiber optic ports operate only at 100 Mbps, but can be manually
configured to either half- or full-duplex. When using full-duplex, you can
run a fiber optic link up to 2 kilometers (1.24 miles). However, when
using half-duplex, you can only run a link up to 412 meters (0.25 miles).
Note that timing constraints must also be considered when calculating
the maximum cable length for your specific environment.
