Incident

CLOSED
100%
We have reports about alarms from the transport equipment DWDM on the section between Postling and Mereworth. We have doubts that an intervention is in progress
with another operator on at least one of this sites and that this generates span loss variations on our link.

We are working on this problem with the maintainer of the cable.

A maintenance is programmed this night in order to securise definitively the link and avoid eventually new stability problem. The maintenance window streches from
00:00 to 06:00 CET. Several cuts can occur during this time.

The maintenance is done . The intern fiber cables on the
amplification site of Mereworth (UK) were checked. We are
currently waiting for the return of the technicians to the
spot in order to have more details about the eventual
notices anomalies.

The techs have indeed detected a fault on one of the internal bypasses and re-welded the fiber. Now the problem is definitely solved.
