Multiple-Common (Scg-D) Switch Configuration; Single-Step Multiple-Common (Scg-E) Switch Configuration - JDS Uniphase SCG Series User Manual

Multiple-Common (SCG-D) Switch Configuration

The multiple-common (SCG-D) switch configuration provides simultaneous connection of a
bank of inputs to outputs (Figure 2). Input 1 can be connected to 1-1 or any 1-M/N output. In this
configuration, channel connections are stepped by groups. The number of states is equal to the
number of output channels divided by the number of input channels.

Single-Step Multiple-Common (SCG-E) Switch Configuration

The non-blocking single-step multiple-common (SCG-E) configuration allows any input to be
connected to any output. At the same time, adjacent inputs align with adjacent outputs (Figure
3). This configuration allows for single-step movement of any input channel to any output
channel.
