width track

(1/1)

alamwte:
Hello,
I want to design a SFP 10gbit module.
But I don't know what is the minimum width track for signal pins.
Would you tell me its minimum track width?
thanks

dunkemhigh:
At a quick guess there are two lobes of a Venn diagram here:

1. Minimum width is what your PCB manufacturer can support.

2. Actual width will depend on how close your ground plane is and the impedance you need for the high speed.

Thank tou so much.
