Tracker: Use cases
Title: undirected links
Description:
In some FttH networks, a IEEE standard is used where traffic in both directions is using a single strand of glass fiber 
on different wavelengths. The upstream is using 1310 nm, while the downstream uses 1550 nm. This is an example of a 
bidirectional connection using an underlying undirected medium.

  Comment:
FYI, examples of such standards are:

* ITU-T Recommendation G.985
* IEEE 802.3ah 100BASE-BX10
* IEEE 802.3ah 1000BASE-BX10
