1 GbE 10 km SFP, 1000BASE-LX (duplex LC, SMF, 1310 nm, OM) 45W2816 2212
1 GbE 70 km SFP, 1000BASE-LHA (duplex LC, SMF, 1550 nm, OM) 45W2817 2213
10 GbE 10 km, SFP+, 10GBASE-LR (duplex LC, SMF, 1310 nm,
OM)
45W4264 2131
Note: OM = Optical Monitoring supported. SMF = single-mode fiber. MMF = multi-mode fiber. MMF
distance supported depends on cabling type. Use OM3 50 ìm (2000 MHz*km) MMF to support the farthest
distances.
The B24X has twenty-four dual-speed 10/1 GbE SFP+ ports enabling customers to seamlessly transition
their 1 GbE devices to 10 GbE speeds by upgrading the transceiver. Qualified SFP+ or SFP transceivers
are required for each SFP+ port and are not included. Up to twenty-four 10 GbE SFP+ or 1 GbE SFP
transceivers are supported on each IBM Ethernet Switch B24X.
10 GbE SFP+ optical –SR (10GBASE-SR) transceivers support distances up to 300 m, which is ideal for
connectivity within a data center. 10 GbE SFP+ optical –LR (10GBASE-LR) transceivers support extended
distances up to 10 km.
