  • Publication number: 20230071759
    Abstract: A method for increasing the capacity of a passive optical network. The passive optical network includes an existing multi-service terminal having a plurality of hardened fiber optic drop ports, and also includes an optical line terminal that provides service to the existing multi-service terminal. The method includes upgrading the optical line terminal to support at least 10GPON and to have increased launch power and enhanced loss sensitivity. The method also includes adding a passive optical splitter between the optical line terminal and the existing multi-service terminal, connecting the existing multi-service terminal to a first output of the passive optical splitter, and connecting an expansion multi-service terminal to a second output of the passive optical splitter.

  • Publication number: 20220050251
    Abstract: Distributed optical tapping architectures include two or more optical tap terminals daisy-chained together. Each optical tap terminal includes an environmentally sealed enclosure; an optical tapping circuit positioned within an interior of the enclosure, the optical tapping circuit including an tap input, a tap pass-through output, and a tap drop output; and hardened interface locations (e.g., de-mateable fiber optic connection locations, cable-pass through glands, etc.) corresponding to the tap input, the tap pass-through output and the tap drop output.

  • Publication number: 20130216187
    Abstract: A passive optical network includes one or more multi-service terminals each having a housing and a plurality of ruggedized plug-receiving distribution ports accessible from outside the housing. The multi-service terminals also each include an optical power splitter or wave division multiplexer for splitting an optical signal and directing the split signal to the plug-receiving distribution ports. Some of the multi-service terminals provide a different power split ratio from others of the multi-service terminals.
