5.4 Multiple Switches connected in series

Fiber Optic Switches can be connected in series as shown above. This however leads to additional optical
losses occurring in the system due to multiple switches. Each Fiber Optic Switch adds <4dB (typical 3dB) loss.
When using the switches with a Fiber Optic Interface, refer to FOI Operation Manual (ANNEX A) for a detailed
optical power margin calculation and the maximum number of switches that can be connected in series.
