Operating at 1310 nm wavelength over single-mode fiber (SMF), the Cisco GLC-LH-SM delivers Gigabit Ethernet connectivity with a maximum reach of 10 km—ideal for enterprise campus networks and metropolitan area deployments. This SFP transceiver also supports multimode fiber (MMF) connections up to 550 m when paired with a mode-conditioning patch cable, providing flexible deployment options for network engineers modernizing their optical infrastructure.

The Cisco GLC-LH-SM (part number GLC-LH-SM) is a 1000BASE-LX/LH compliant transceiver operating at 1.25 Gbps with full-duplex transmission over ITU-T G.652 standard fiber. Built on the SFP MSA form factor, it features an LC duplex connector interface and supports hot-swappable operation for zero-downtime module replacement. Digital Optical Monitoring (DOM) capability enables real-time diagnostics, while the commercial operating temperature range of 0°C to 70°C ensures reliable performance in standard data center and network closet environments. Cisco's IOS integrity check certification guarantees authenticated compatibility across supported platforms.

Enterprise Deployment Scenarios

• Long-reach campus backbone links connecting multiple buildings across 10 km distances using single-mode fiber infrastructure
• Metropolitan area network (MAN) expansion where organizations require standards-compliant Gigabit connectivity beyond traditional short-reach deployments
• Multimode fiber environments leveraging mode-conditioning technology to extend effective reach to 550 m on existing legacy cabling
• Hot-swappable transceiver environments where network uptime is critical and scheduled maintenance windows are limited
• Optical diagnostic and monitoring operations using built-in DOM support to track signal integrity and transceiver health metrics
