I have a 10G XPF+ optical cable with market updates from a stock exchange. This cable goes into a switch, which then multicasts every packet to a couple of computers. The problem with using a switch for multicast is that there is latency overhead, even with a pass-through switch (~200ns).

Are there "optical" solutions (I'm thinking of a beam splitter of some sort) which would allow for close to zero latency 10G multicast?
