The NPE-G2 supports single Gigabit Ethernet interfaces based on SFP technology. The following SFP modules are supported by the NPE-G2:

•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 between switches over multimode fiber (MMF) infrastructures. The 100BASE-FX SFP operates on ordinary MMF optical link spans of up to 6562 ft (2 km) in length. Customers implementing Cisco 100BASE-FX SFP can use 1000BASE-X SFP modules in the future (including SX, LH/LX, ZX, and coarse wavelength-division multiplexing SFP modules).

•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 32,808 ft (10,000 m) in length.

•1000BASE-SX SFP—The SFP-GE-S=, 1000BASE-SX SFP module operates on ordinary multimode fiber-optic link spans of up to 1804 ft (550 m) 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 43.5 miles (70 km) in length. Link spans of up to 62.1 miles (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 15.5 miles (25 km).

Note Optical fiber cables are commercially available; they are not available from Cisco.

Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the “Fiber Optic Cleaning Information” section on page 6-23for information.
