Racks for transmission  equipment  of  DWDM optical platform in one of the buildings  of Telekomunikacja Kolejowa (Railway Telecommunications).


Detailed designs of telecomunications equipment for DWDM optical platform and signalling overlay network SDH-STM16 with management and supervision network.

The detailed designs were  prepared for the first in Poland optic transmission network of Telekomunkacja Kolejowa (Railway Telecommunications) that  is also used by Poznanskie Centrum Superkomputerowo Sieciowe. The network connected  major cities of Poland and further reached beyond the state border to Berlin and Frankfurt am Main.

This installation includes the most modern 32-channels DWDM system of 2,5 Gbit/s capacity that can be easily increased to 10 Gbit/s.

The network is still being extended with participation of our designers.
