GLC-T



The GLC-T 1000BASE-T SFP operates on standard Category 5 wiring of up to 100m link length.

Return to Top

GLC-ZX-SM



The GLC-ZX-SM, 1000BASE-ZX SFP operates on ordinary single-mode fiber optic link spans of up to 70 kilometers (km) in length. Link spans of up to 100 km are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. The SFP provides an optical link budget of 23 dB-the precise link span length will depend 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 GLC-ZX-SM at each end of the link whenever the fiber optic cable span is less than 25 km.
