* Freek to write use case on bidirectional and unidirectional links: single fiber with two wavelengths in different directions.
In some FttH networks, a IEEE standard is used where traffic in both directions is using a single strand of glassfiber on different wavelengths. The upstream is using 1310 nm, while the downstream uses 1550 nm. This is an example of a bidirectional connection using a -seemingly- unidirectional medium. https://forge.ogf.org/sf/go/artf6533 Freek
