  • Patent number: 6628440
    Abstract: A system for diverting an optical component signal from a multiplexed optical signal includes an optical communications channel having a first portion and a second portion. A multiplexed optical signal having a plurality of component signals may be transmitted through the optical communications channel. Each component signal lies within a different optical bandwidth. The system also includes a branch optical channel having a first section and a second section. A signal diverter that optically couples the first portion of the communications channel to the second portion of the communications channel directs a diverted portion of the multiplexed optical signal into the first section of the branch optical channel. The signal diverter also allows a non-diverted portion of the multiplexed optical signal to propagate into the second portion of the optical communications channel.
