SFP ports.
The NPE-G2 supports single Ethernet interfaces based on SFP module technology. The following SFP
modules are supported by this line card:
100BASE-FX SFP—The SFP-GE-F=,100BASE-FX SFP module is a hot-swappable device that
•
plugs into a Gigabit Ethernet SFP port. It provides full-duplex 100-Mbps connectivity over
multimode fiber (MMF) infrastructures. The 100BASE-FX SFP operates on ordinary MMF optical
link spans of up to 2 kilometers (km) in length.
1000BASE-LX/LH SFP—The SFP-GE-L=, 1000BASE-LX/LH SFP module operates on ordinary
•
single-mode fiber-optic link spans of up to 10,000 meters in length.
1000BASE-SX SFP—The SFP-GE-S=, 1000BASE-SX SFP module operates on ordinary
•
multimode fiber-optic link spans of up to 550 meters in length.
1000BASE-ZX SFP—The SFP-GE-Z=, 1000BASE-ZX SFP module operates on ordinary single
•
mode fiber-optic link spans of up to 70 kilometers in length. Link spans of up to 100 km are possible
using premium single-mode fiber or dispersion-shifted single-mode fiber. The SFP module provides
an optical link budget of 23 dB—the precise link span length depends on multiple factors such as
fiber quality, number of splices, and connectors.
When shorter distances of single-mode fiber are used, it may be necessary to insert an inline optical
attenuator in the link to avoid overloading the receiver. A 5-decibel (dB) or 10-dB inline optical
attenuator should be inserted between the fiber-optic cable plant and the receiving port on the
SFP-GE-Z= at each end of the link whenever the fiber-optic cable span is less than 25 km.
The required line card SFP module is shipped installed in the line card. Cisco sells individual SFP
Note
modules separately and you can change the type of Gigabit Ethernet interface supported by this line card
by simply changing its SFP module.
Optical fiber cables are commercially available; they are not available from Cisco Systems.
Note
We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the
