Ticket Description: interruption of fiber link to ENSI

Problem Description:

Two of three links to ENSI in Brugg are interrupted. These two links use the same fiber pair for the last mile between Brugg station to ENSI. Most likely - there is an interruption of fibers in this segment. We are investigating the problem with the fiber providers involved.

IBB found the position where the tube was damaged.
They hope to be able to repair the cable without replacing the whole cable.

A OTDR measurement by SWITCH located a fiber interruption of the local loop 107 m from Brugg railway station in direction to ENSI.
The reason might be civil engineering works close by.
Tomorrow morning IBB will start with repair.

We informed IBB about the interruption.
They are not aware of a problem yet - but they are looking into it.
