Gurus, I would like to send 12 signals from one VME/VXI board to 6 adjacent boards without wires. Does anyone know of an optical or electromagnetic or any other means to send/receive these signals? One of the signals is a clock. Data rate is 50 to 100 MHz. Delay between the sending board and the receiving boards is not critical. Delta delay differences between the nearest and furthest "receiving" boards can be corrected for...up to 5ns). Signal skew and jitter, though, needs to be less than 1ns. The boards can have holes for the optical "signals" to pass through. Board spacing is 1.2" All boards are identical, but the sending board can be restricted to be at the end or the middle. Actually, the sending board also needs to receive the signals.
