Cisco WS-G5487 GBIC Transceiver Module – 1000BASE-ZX 1550nm, Duplex SC, Up to 100km
The Cisco WS-G5487 is a 1Gbps Gigabit Interface Converter (GBIC) designed for extended-distance Gigabit Ethernet fiber networking. It supports the 1000BASE-ZX interface and operates at a nominal wavelength of 1550nm over single-mode fiber.
With its long-distance optical design, the WS-G5487 can support link spans of up to 70km over ordinary single-mode fiber. Cisco documentation states that distances of up to 100km are possible when using premium single-mode fiber or dispersion-shifted single-mode fiber, subject to the optical loss and dispersion characteristics of the installed link.

Long-Distance Fiber Connectivity
The Cisco WS-G5487 is intended for long-distance Gigabit Ethernet links where extended optical reach is required. Unlike the WS-G5484 1000BASE-SX GBIC designed for multimode fiber or the WS-G5486 1000BASE-LX/LH GBIC designed for approximately 10km single-mode links, the WS-G5487 is an extended-distance 1000BASE-ZX solution.
Cisco specifies up to 70km on ordinary single-mode fiber. Up to 100km can be achieved with appropriate premium single-mode or dispersion-shifted fiber. Actual achievable distance depends on fiber attenuation, dispersion, connectors, splices, and the complete optical link budget.
Optical Link Budget
The WS-G5487 provides a substantial optical power budget for extended-distance applications. Cisco documentation specifies a minimum optical power budget of approximately 23dB. Optical loss testing should be performed on the installed cable plant to verify that the total link loss remains within the supported optical budget.
Applications
- Long-distance Gigabit Ethernet backbone links
- Campus network interconnection
- Metro-area fiber network connectivity
- Switch-to-switch long-haul fiber links
- Router-to-router Gigabit Ethernet connectivity
- Legacy Cisco Catalyst and router GBIC deployments
- Telecommunications and extended-distance fiber infrastructure
Compatibility
The WS-G5487 is designed for Cisco networking equipment with compatible GBIC ports and software support for the 1000BASE-ZX interface. Cisco documentation lists the WS-G5487 for compatible Catalyst switches, routers, and Gigabit Ethernet line cards.
Compatibility should be verified against the exact Cisco platform and software release before purchase. The WS-G5487 is a legacy GBIC form factor and is not interchangeable with modern SFP or SFP+ modules.
Important Fiber Compatibility Note
The WS-G5487 is intended for single-mode fiber and should not be connected to multimode fiber. For links approaching the maximum supported distance, the complete optical path should be engineered and tested for attenuation and chromatic dispersion.
