[QUOTE="pwatts, post: 1178992, member: 146"] Direct-Attach is an excellent method to save on cost and power consumption, but for this purpose it's not ideal since it's not galvanically isolated like when used with optical modules or BASE-T copper modules with integrated transformers (same reason why I2S over HDMI cables can be a step backwards in many cases). It is literally just a very good set of shielded twisted-pair conductors and AC-coupling capacitors to directly connect two transceivers, hence the short maximum cable length. [/QUOTE]
