We want to migrate several Gigabitlinks over a DWDM Solution , the problem is.
If the DWDM switch over to the Backup Darkfiber the DWDM switch of the light for 50 ms to the Cisco Switch , the result is a link down on the Switchport.
so, how long can be no light on a Gbic till it goes down.

50 ms switchover should not cause the gigabit link to go down. Do you actually see the system logging message indicating a link failover? Also, are you absolutely sure the DWDM is doing a fast trunk failover?
See this doc for more details:

this link is really good, but we have 2950 Switches and the don´t know the debounce command.
The Command on IOS Switches is fist introduced in
12.2(14)SX
Support for this command was introduced on the Supervisor Engine 720.
12.2(17d)SXB
Support for this command on the Supervisor Engine 2 was extended to the 12.2 SX train.
