Wideband CMTS Components Chapter 2 Cisco Cable Wideband Components The Cisco uBR10012 router can support up to two Wideband SPAs. Each Wideband SPA can support up to 12 logical wideband channels (bonding groups). Depending on how it is configured, each Wideband SPA allows up to 24 RF channels. Each logical wideband channel consists of multiple RF channels. The Cisco IOS CLI includes a set of commands to configure the Wideband SPA on the Cisco uBR10012 router. The two Gigabit Ethernet ports on the Wideband SPA use small form-factor (SFP) modules (see Figure 2-8). An SFP module is an input/output (I/O) device that plugs into the Gigabit Ethernet SFP ports on the Wideband SPA, linking the port with an edge QAM device through a fiber-optic network.
