A method and system for maximizing wavelength reuse in an optically protected wavelength-division-multiplexed (WDM) network, the WDM network supporting a plurality of service connections, includes associating service connections supported by non-overlapping paths to form respective service channel groups, and for each service channel group, assigning at least one common wavelength channel for establishing the service connections. In addition, for each of said groups, at least one common wavelength channel is assigned for establishing a shared protection path for the service connections of each of said groups. In addition, the wavelength channels assigned for establishing the shared protection paths for each of the groups may be used for providing service connections for the WDM network when not in use as shared protection paths. However such provisional service connections are dropped when the wavelength channels are needed to establish shared protection paths. Such provisional service connections may be offered at reduced cost.

In a system for charging a rechargeable battery, an electrical device powered by a rechargeable battery has a body that fits into a receiving cavity in a charging base for recharging the battery. The electrical device is provided with a retractable charging terminal mechanism that causes a terminal leading to the rechargeable battery to protrude from the body of the electrical device to make contact with a recessed electrical contact in the base when the electrical device is seated in the base cavity and retracted back into the body of the electrical device when it is removed from the base cavity.
