Fiber optic errorless switching system

Not applicable An errorless switching system is disclosed that is comprised of a fault detector, a synchronization system, and a switching system. The synchronization system aligns a first data signal and a second data signal. The fault detector detects errors in the data signals and instructs the switching system to transfer the first data signal or the second data signal to avoid transferring the erroneous data. No data is lost or duplicated because the data signals are aligned at the switching system.
