Abstract
A bi-directional optical transceiver includes multiple single mode optical ports and a multi-mode optical port. A multi-mode optical combiner combines single mode optical signals received at the single mode optical ports into a multi-mode optical signal at the multi-mode optical port. Each single mode optical signal having a distinct optical mode that does not interfere with the optical mode of the other single mode optical signals. A photo detector coupled to the multi-mode optical combiner detects a total optical power of the single mode optical signals in the multi-mode optical signal.
