AddOn GLC-LH-SM-AO 1000Base-LX/LH SFP Transceiver Module F/Cisco

1000Base-LX/LH SFP module for Cisco networks

The AddOn GLC-LH-SM-AO transceiver provides a hot-swappable SFP interface for single-mode fibre links at 1 Gbps. It carries OEM-specific configuration data so it registers and operates identically to the original Cisco module. Network engineers can deploy it in existing switches and routers without reconfiguration or downtime.

Hot-swappable SFP form factor with LC connectors

Weighing 0.06 pounds and measuring 0.33 x 2.22 x 0.53 inches, the module slides into any standard SFP cage while the link stays live. Dual LC receptacles accept standard single-mode patch cords for long-haul campus or metro connections. The design is 100 % compliant across the supported product lines and interoperates with other OEM or third-party transceivers on the same link.

Lifetime warranty replaces 90-day OEM coverage

The unit ships as a direct replacement part with no additional cables, software licences or media required. The extended warranty period removes the recurring cost of short-term OEM support contracts. Buyers who need multi-mode reach, higher speeds such as 10 Gbps, or non-Cisco coded modules should select a different part number.
