Cisco WS-G5484 1000BASE-SX GBIC Transceiver Module
The Cisco WS-G5484 is a 1000BASE-SX GBIC module for multimode fiber, delivering 1Gbps connectivity up to 550 meters
Cisco WS-G5484 is a 1000BASE-SX GBIC Module for multimode fiber, delivering 1Gbps connectivity up to 550 meters. Matching on sight is unreliable here. The part number is what determines whether it will work in a given chassis.
Reach is a budget, not a promise. The distance printed on an optic is what it achieves over clean fibre with the stated loss. Every connector, splice and patch panel in the path spends part of that budget, so a link that measures within distance on paper can still fail on insertion loss. Check the form factor and rate first, then work out the real budget for the route rather than the straight-line distance.
How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Quote the equipment it is for when you ask and we will verify the fit first. We come back by the next working day.
The Cisco WS-G5484 is a Gigabit Interface Converter (GBIC) transceiver module. It is designed to provide Gigabit Ethernet connectivity over multimode fiber (MMF).
This module supports the 1000BASE-SX standard, operating at a wavelength of 850 nm. It delivers reliable short-range fiber connectivity for enterprise and campus networks.
The WS-G5484 supports distances up to 550 meters over multimode fiber, depending on fiber type and quality.
It features a dual SC connector, ensuring compatibility with legacy fiber infrastructure and Cisco networking equipment such as older Catalyst switches and routers.
The module is hot-swappable, allowing installation or replacement without interrupting network operations.
This GBIC is typically used for:
- Switch-to-switch uplinks
- Campus fiber connections
- Data center short-range links
- Legacy Cisco platforms with GBIC slots
⚠️ Note:
The GBIC form factor is obsolete and has been replaced by SFP (mini-GBIC) modules. This model is mainly used for legacy equipment maintenance.
