Classic Gigabit Ethernet Fiber Line Card (GBIC or SFP)
The Cisco Catalyst 4500 Series offers a variety of gigabit interface converter (GBIC) - or Small Form Factor
Pluggable (SFP)-enabled gigabit solutions for high-performance Gigabit Ethernet uplinks and server farm
connectivity. The five GBIC- or SFP-enabled gigabit line-card options for the Cisco Catalyst 4500 Series include 6-,
18-, and 48-port versions. GBIC or SFP technology allows customers to intermix intrabuilding multimode fiber
(MMF) connections and long-distance single-mode connections simply by changing the GBIC or SFP type.
(See Table 3 for more information.)
