Cisco GLC-ZX-SMD Transceiver Module – 1000BASE-ZX Gigabit Ethernet SFP
The Cisco GLC-ZX-SMD is a 1000BASE-ZX Gigabit Ethernet Small Form-Factor Pluggable (SFP) transceiver designed for long-distance optical network connectivity. It operates at a nominal 1550nm wavelength over single-mode fiber (SMF).
The GLC-ZX-SMD is suitable for long-distance enterprise, campus, service-provider, metro Ethernet, and network backbone applications. Cisco documentation specifies a cable distance of approximately 70 to 100 kilometers, depending on the optical link design and deployment conditions.

Optical Performance
The Cisco GLC-ZX-SMD uses 1550nm optical transmission over single-mode fiber for extended-distance Gigabit Ethernet links. Its long-reach design makes it suitable for network connections that exceed the typical 10km or 40km reach of shorter-range Gigabit Ethernet optics.
70–100km Long-Distance Connectivity
Cisco documentation specifies approximately 70 to 100km of cable distance for the GLC-ZX-SMD. The actual achievable distance depends on fiber characteristics, connector losses, optical attenuation, dispersion, and overall link engineering.
For engineered links, appropriate optical attenuation and link-budget considerations may be required, particularly when the actual fiber span is substantially shorter than the optic's maximum design distance.
Applications
- Long-distance Gigabit Ethernet links
- Enterprise network backbone connections
- Campus network interconnections
- Metro Ethernet infrastructure
- Service-provider network connectivity
- Data center and remote-site interconnects
- Building-to-building fiber links
- Long-haul network aggregation and distribution
Compatibility
The Cisco GLC-ZX-SMD is designed for Cisco networking platforms supporting the 1000BASE-ZX SFP. Cisco documentation identifies the module for compatible switching, routing, and network convergence platforms.
The module uses a dual LC/PC interface and requires single-mode fiber. Verify the exact Cisco platform, software/firmware support, optical budget, and supported transceiver list before installation.
The remote end should use a compatible Gigabit Ethernet optical interface with matching wavelength and optical characteristics.
