The SFP (Small Form-Factor Pluggable) module is a hot-swappable input/output
device that plugs into the fiber ports.
If you install an SFP module after the switch has powered on, you must reload the
adaptive security appliance to enable the SFP module.
Table 3-1 lists the SFP modules that are supported by the adaptive security
appliance.

1000BASE-LX/LH
1000BASE-SX
The 1000BASE-LX/LH and 1000BASE-SX SFP modules are used to establish
fiber connections. Use fiber cables with LC connectors to connect to an SFP
module. The SFP modules support 850 to 1550 nm nominal wavelengths. The
cables must not exceed the required cable length for reliable communications.
Table 3-2 lists the cable length requirements.
