DescriptionEye pattern long stub.png
English: Eye pattern of a 1000base-SX Ethernet data stream, converted from optical to electrical using a SFP module, digitized with a Teledyne LeCroy WaveRunner 8404M-MS oscilloscope, and rendered with glscopeclient.
A stub about four inches long in the transmission line degrades the signal to the point of being unrecognizable.
