Ticket Description: Fiber interruption between Bellinzona and Faido

Problem Description:

There is an interruption of the SBB fiber between Bellinzona and Faido.
SUPSI and USI is without redundancy. All traffic is rerouted over the backup path.
The cross border connection CNAF-GRIDKA-LHCOPN-001 is interrupted.
The reason of the fiber cut are rodents. In order to fix the cable, SBB had to install an extra splicing box in a tunnel. It explains the small attenuation increase we noticed. SBB plans to remove the splicing box (by replacing the complete cable segment) in early 2012.
