Abstract
An optical connection arrangement is provided in an optical path to facilitate changing optical add/drop multiplexer (OADM) and other optical component modules while optical traffic is present on the optical path, with minimal interruption to such traffic. The connection arrangement has a plurality of optical ports to each of which an optical component can be coupled, and one or more optical switches which can be controlled to selectively include in the optical path or bypass each optical port. Such connection arrangements can be coupled in series and/or in parallel for convenient modular add/drop configurations and for opposite directions of transmission of optical traffic on respective optical paths.
