摘要
The switching unit has an optical n * m spatial switch (ORS) with n + m connections where n and m are integers greater than or equal to 1. Several devices (K1A,K1B,...) are used for monitoring the optical signals applied to at least one connection (P1A,P2A,...) on either side of the optical switch. The monitoring devices control the position of the optical switch according to the monitored optical signals. The monitoring devices can monitor all signals entering and leaving the optical switch.
