Cisco SFP-GE-L Transceiver 1000BASE-LX/LH LC DOM

Brand:

The Cisco SFP-GE-L is a Gigabit Ethernet optical transceiver designed for long-reach 1000BASE-LX/LH connectivity over single-mode fiber with LC interface and Digital Optical Monitoring (DOM). It enables reliable 1 Gbps fiber links for enterprise campuses, data centers, and metro networks, supporting stable high-speed connectivity across extended distances.

OVERVIEW

  • The Cisco SFP-GE-L is a Gigabit Ethernet small form-factor pluggable (SFP) optical transceiver designed for long-reach 1000BASE-LX/LH fiber connectivity. It provides stable 1 Gbps data transmission over single-mode fiber using LC duplex connectors and includes Digital Optical Monitoring (DOM) for real-time diagnostics and performance visibility.
  • Within Cisco’s Gigabit SFP portfolio, this module is positioned for enterprise-grade backbone and aggregation layers where reliable fiber connectivity is essential across campuses, data centers, and metro networks. Compared to short-range SX modules, the LX/LH variant extends operational reach significantly, enabling organizations to connect distributed infrastructure without signal degradation or additional active equipment. It is widely used in enterprise network modernization, hybrid cloud connectivity, and high-availability network architectures where predictable performance and lifecycle stability are critical.
