A bridge and roll method for doing an in-service switch (less than 50 ms) from one set of inputs and outputs on a primary photonic switch to another set of inputs and outputs on the same or a secondary photonic switch. The bridge and roll method facilitates maintenance, repairs and upgrades on the primary photonic switch. The bridge and roll method may be reversed in order to restore the original inputs and outputs on the primary photonic switch after maintenance, repairs or upgrades have been performed. The invention also provides a method for consolidating multiple wavelengths or multiple bands into single fibers.
