Abstract
Fiber optic terminals with wavelength division multiplexing (WDM) and connection ports supporting physical path redundancy for communication networks are disclosed. The fiber optic terminals provide multiple paths for optical communications. The fiber optic terminal comprises a shell that defines a cavity with at least one primary wavelength division multiplexing (PWDM) device and at least one redundant wavelength division multiplexing (RWDM) device disposed within the cavity of the shell.
