The service was not interrupted.
Reason for closing: Done
An intervention is in progress.
The interruption between MIC92 and BGN92 on a single strand.
On BGN tests were performed to check the fiber.
From the unbundling room to RO, it is OK.
We will go on MIC92 to perform the same thing.
The suspected fault is a constraint on one of the strand.
We are waiting for FT to access in a closed local
in the NRA.
Two welds were made in a box outside the main distribution frame. We lost 0.9dB and 1.3 dB. The signal remains in the allowed range. It is now secure.
