5484: GBIC Transceiver Model Identifier
Core Product Positioning
The Cisco WS-G5484 is a hot‑swappable GBIC (Gigabit Interface Converter) optical transceiver compliant with IEEE 802.3z 1000BASE‑SX standard. It delivers short‑reach Gigabit Ethernet connectivity over multi‑mode fiber for enterprise campus switching environments. Designed for Catalyst modular switches, it enables fiber uplinks, inter‑switch links and server SAN connectivity over low‑cost multi‑mode cabling infrastructure. This legacy GBIC form factor provides reliable wire‑speed Gigabit optical transmission for traditional data center and building backbone deployments.
2. Hardware & Software Compatibility
