FS#349 — FS#4428 — paris/madrid

Attached to Project— Network
Incident
Whole Network
CLOSED
100%
One of the 10G which we have between Paris and Madrid has crashed.
After the researches we have conducted, we have found that the optical power
in reception is very weak.

Transceiver monitoring is disabled for all interfaces.

ITU Channel not available (Wavelength not available),
Transceiver is internally calibrated.
If device is externally calibrated, only calibrated values are printed.

We cut off the link and we will look for the origin of the
problem: either a constraint on the fiber optic or the optics
in the opposite is very weak.

The second link has just crashed.

The equipment in the opposite no longer send out light.
It is due to the maintenance task in Spain.

The traffic moves via the second link 2x10G which
we have in place. Therefore, there is no deterioration
of the service.

The maintenance tasks were finished. The link is up again.
