Wideband CMTS Components Figure 2-5 SFP Module for HHGE Line Cards Chapter 2 Cisco Cable Wideband Components 76415 Mylar tab Bale clasp The following SFP modules are supported by the HHGE line card: • 1000BASE-SX SFP-The SFP-GE-S, 1000BASE-SX SFP operates on ordinary multimode fiber optic link spans of up to 550 meters in length. • 1000BASE-LX/LH SFP-The SFP-GE-L, 1000BASE-LX/LH SFP operates on ordinary single-mode fiber optic link spans of up to 10,000 meters in length. • 1000BASE-ZX SFP-The GLC-ZX-SM, 1000BASE-ZX SFP operates on ordinary single-mode fiber optic link spans of up to 70 kilometers (km) in length. Link spans of up to 100 km are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. The precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors. The HHGE line card supports online insertion and removal (OIR) and can be added or removed without powering off the chassis. For more information on the HHGE line card, refer to the Cisco uBR10012 Universal Broadband Router Hardware Installation Guide. Wideband CMTS Components A Cisco uBR10012 base system can be upgraded to a wideband CMTS by adding these components: • Wideband SIP and Wideband SPA, page 2-8 • External Edge QAM Device, page 2-11 For information on the wideband CMTS functionality, see the "Modular CMTS" section on page 3-4. Wideband SIP and Wideband SPA The Wideband SIP and Wideband SPA needed for wideband cable can be added to the base Cisco uBR10012 system when they are required. For the Wideband SIP and Wideband SPA, Table 2-3 lists the minimum and recommended hardware configurations. Cisco Cable Wideband Solution Design and Implementation Guide, Release 1.0 2-8 OL-10705-02
