About Fabric Cards
The Cisco NCS 4016 chassis supports 4 fabric cards (FCs), which are agnostic cross-connects based on a
flexible cell switching architecture used in a Clos configuration. FCs are called agnostic because they will
switch a cell with no knowledge of whether they belong to OTN switching or Ethernet switching. Each fabric
card hosts three fabric devices, which are equally distributed across the 16 line cards.
FCs provide the switch fabric for the routing system and perform the cross-connect function of the routing
system, connecting every LC to each other. The switch fabric receives ingress user data from one LC slot and
performs the switching necessary to route the data to the appropriate egress LC slot.
The Cisco NCS 4016 chassis supports, the 200G and 400G fabric cards. The 400G fabric card enables 400G
traffic using the 400G line card. The datapath link speed of 400G FC-LC is twice that of the 200G FC-LC.
