From the project
Pluggable SFP Module Breakout
Work-in-Progress - First Revision gerbers being tested.
Pluggable SFP (SFF INF-8074i) and SFP+ (SFF-8432) Module Breakout for developing SFP modules. PCB must be manufactured with a 1.0mm thickness.
Similar Projects: SFP-Breakout-Board, SFPBreakoutBoard, SFP-Loopback-Board, and Sfp-breakout(osmocom.org*).
Differential pair parameters were calculated based on a board thickness of 1.0mm.
