beams or view directly with optical instruments. Statement 272
GBICs and SFPs/XFPs are input/output devices that plug into a Gigabit Ethernet card to link the port
with the fiber-optic network. The type of GBIC or SFP determines the maximum distance that the
Ethernet traffic can travel from the card to the next network device. For a description of GBICs and SFPs
and their capabilities, refer to the Cisco ONS 15454 Reference Manual.
GBICs and SFPs must be matched on either end by type: SX to SX, LX to LX, or ZX to ZX.
Note
All versions of G1K-4 cards support coarse wavelength division multiplexing (CWDM) GBICs.
Note
GBICs are available in two different models. One GBIC model has two clips (one on each side of the
GBIC) that secure the GBIC in the slot on the E1000-2-G, G-Series, or G1K-4 card. The other model
has a locking handle. Both models are shown in
