Quantum Network Bridges can connect two networks over infinite distances and even between dimensions.
Eight of these blocks placed around a ME Quantum Link Chamber will create a Quantum Network Bridge. Only the 4 ME Quantum Ring blocks adjacent to the ME Quantum Link Chamber will accept network connections, the 4 corner blocks cannot connect to cables.
Quantum Link Chamber
One of these blocks surrounded by a ME Quantum Ring will create a Quantum Network Bridge. This block doesn't connect to any cables and only registers as part of the network with the full bridge is made.
This blocks inventory can only hold a single Quantum Entangled Singularity and is automation accessible.
Quantum Entangled Singularity
Required to create a connection between to Quantum Network Bridges, they are always produced in matching pairs, to create a connection place 1 of the pair of Quantum Entangled Singularity into the ME Quantum Link Chamber of the bridge on each side.
Nearly any explosion - even creepers - will work.
Always produced in pairs, but only require a single Singularity.
It might be a good idea to label these with names when you create them using the vanilla anvil.
Note for Anti Griefing Servers
AE also includes a block called Tiny TNT, this is a small craftable TNT which can have its block damage disabled, but can still hurt a little, and can be used as an alternative to vanilla tnt / other explosions even when block damage is disabled.
