SFP AC parameters
Each SFP is a TTL schmitt trigger bidirectional pad Buffer, 3v3 capable with 2mA drive capability
and Slew-rate Control. The 3.3V IOs comply to the EIA/JEDEC standard JESD8-B. For sake of
convenience the most important parameters for measurement have been extracted and presented
below.
