Chapter 2 Cisco Cable Wideband Components
Wideband CMTS 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.

Table 2-4
lists the SFP modules that the Wideband SPA supports.
