1000BASE-ZX SFP for Long-Reach Single-Mode Fibers
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 fiberoptic
cable span loss is less than 8 dB.
