FEX cable limitations

[ssieger]

Hi,

is there any restriction about the distance between a fex and its 5548UP parent switch? The N2K-C2248TP-E-1GE is able to support the following SFP's:

SFP-10G-SR
SFP-10G-LR
FET-10G2
SFP-10G-ER
SFP-H10GB-CU1M
SFP-H10GB-CU3M
SFP-H10GB-CU5M
SFP-H10GB-ACU7M
SFP-H10GB-ACU10M

So if i use a LR SFP is it possible to put my fex 10km away from its parent switch ?

Greetings,

Stephan
