Abstract
Techniques for communications using optical fiber are disclosed. An optical add/drop multiplexer (OADM) node includes an interface to a first fiber pair connecting a first trunk station and a second trunk station. The OADM node further includes an interface to a second fiber pair connecting the first trunk station and the second trunk station with a branch station. The OADM node includes a plurality of filters configured to provide connectivity between the first trunk station, the second trunk station and the branch station. Other embodiments are described and claimed.
