Fabrics with
depth
greater than one have redundant internal time stages where TSE devices
communicate with TSE devices. These redundant stages can be set to the identity mapping at
startup, and then ignored during system operation.
Figure 6 illustrates the largest single-plane, three-stage fabric that has an aggregate bandwidth of
2560 Gb/s. The difference between this example and the one shown in Figure 5 is that this one
extends the fabric to its full
height
of 64 TSE devices, whereas the fabric in Figure 5 limited the
height
to 32 TSE devices.

(STS-48 Sources = 1024; Aggregate Bandwidth = 2560 Gb/s; TSE Chip Count = 192; TBS Chip
Count = 1024)
Larger TSE fabrics can be constructed in several ways by extending the architectural techniques
shown above. In particular, the fabric shown in Figure 6 can be sliced into two or four
planes
(for
STS-48), yielding fabrics up to 5120 Gb/s or 10,240 Gb/s, respectively. Furthermore, five stages
of TSE devices can be used to build
deeper
fabrics (which permit greater
height
). Additionally,
STS-192 fabrics with up to 16 planes of TSE devices can be constructed.
