Cisco GLC-ZX-SMD is a 1000BASE-ZX SFP for Long-Reach Single-Mode Fiber. The 1000BASE-ZX SFP operates on standard single-mode fiber-optic link spans of up to approximately 70 km in length. The SFP provides an optical link budget of 21 dB, but 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 (SMF) are used, it might be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP at each end of the link whenever the fiber-optic cable span loss is less than 8 dB. Product Details Figure 1 shows the GLC-ZX-SMD can be installed in the switch. Table 1 provides cabling specifications for the SFPs that you install in the Gigabit Ethernet port. Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (multimode and single-mode fiber) is 6.5 feet (2 m).

Note how the mode conditioning patch cord for 62.5-μm fibers has a different specification from the mode-conditioning patch cord for 50-μm fibers. **ITU-T G.652 SMF as specified by the IEEE 802.3z standard. ***Specified at transmission wavelength.
