What are the advantages of a photonic network?

Though both electricity and light travel at the same speed there are important differences in them that can make photonic networks faster: 

There is also a limitation of Ethernet by running in parallel. By running multiple data paths, the data, once traveling on separate paths, has to end up on the other side at the right time. If the timing is off, then you'll end up with out of order information and the data will be corrupted when it reaches the other end. There is a speed limit on that type of data transmission. You can only go so fast until the cable causes minuet time differentials. 

Example: 

The follow sentence is sent out over the wire: 

I am super fast! The receiving side receives the following sentence if not calibrated: Ia ms uepr aft!s All the data is there, it's just jumbled up, thus making it corrupt. With current photonic networks, you don't get that data corruption.
Perhaps the biggest advantage of a photonic network is that there is no electromagnetic (EM) radiation created and they are totally immune to EM interference.This has implications for security: cables carrying current create a magnetic field, and that field could carry information outside of a secured area unless it is carefully shielded. In the intelligence community these signal interceptors are referred to as TEMPEST scanners.In addition because the wiring is not at risk of induced voltage created by a large electromagnetic field (for instance that created by a lightning strike, high-voltage industrial equipment, or a nuclear explosion). This means that a photonic network will not be disrupted by these events, and will not destroy the equipment attached to it if a large EM source occurs near the wiring. Because of these factors photonic networks have important applications in both high-security and high-durability fields, from military aircraft to backup datacenters.
