Core Product Positioning
The Cisco WS-G5486 is a hot-swappable MSA-compliant GBIC (Gigabit Interface Converter) optical transceiver complying with IEEE 802.3z 1000BASE-LX standard. It supports both multi-mode fiber and single-mode fiber for Gigabit Ethernet transmission. Designed for legacy Catalyst modular switches, it delivers reliable long-distance fiber uplinks, inter-switch links and backbone connections for enterprise campus and data center networks. It offers extended reach over single-mode fiber compared to baseline 1000BASE-LX, supporting flexible migration between multi-mode and single-mode cabling infrastructures.
