100 MbE 40 km SFP, 100BASE-FX-LR (duplex LC, SMF, 

1310 nm, OM)

Note: OM = optical monitoring supported. SMF = single-mode fiber. MMF = multi-mode fiber. The MMF 

distance supported depends on the cabling type. Use OM3 50 ìm (2000 MHz*km) MMF to support the 
farthest distances.

No transceivers are required unless an optional interface module is ordered. 

The optional 4-port 10 GbE SFP+ Interface Module (81Y1455) requires 10 GbE SFP+ transceivers for 

connectivity. While these higher-bandwidth ports are typically used for uplinks to an Aggregation or Core 
switch, they can also be connected to end devices such as servers. IronStack is supported over two of 
these 10 Gbps ports. Cee the “IronStack technology”  section for additional details.

Note: The default configuration on the switch sets the first two ports on the optional 4-port 10 GbE SFP+ 

Interface Module as stack ports. To use all ports on the switch as regular Ethernet ports, the global CLI 
command stack disable can be configured to disable stacking. See the 

FastIron Configuration Guide for 

additional configuration details.
