Cisco GLC-GE-DR-LX 1000BASE-LX SFP 1310nm | Enterprise Fiber Optics — GLC-GE-DR-LX

Keep critical fiber links stable with a Cisco SFP designed for long-reach Gigabit Ethernet transport. The GLC-GE-DR-LX supports 1000BASE-LX operation at 1310 nm and is built for environments where consistent optical performance matters more than low-cost shortcuts. This dual-rate transceiver fits Cisco switching and routing platforms that call for a standards-based SFP in enterprise access, campus aggregation, and data center edge roles. Its single-mode fiber orientation makes it a practical choice for uplinks that need distance headroom and predictable signal behavior across structured cabling. For teams refreJTFng aging optics or standardizing spares, this module offers a familiar deployment path with Cisco compatibility and a form factor that integrates cleanly into existing SFP ports. It is a strong fit when you need dependable connectivity for production networks, not just a link that comes up in the lab. Choose this module when the cost of a failed uplink is higher than the cost of the right optic. It helps preserve network continuity, simplify procurement, and keep fiber infrastructure aligned with Cisco hardware expectations.
