Cisco GLC-LH-SMD Gigabit SFP transceiver module, MMF/SMF Multimode & SingleMode

Cisco GLC-LH-SMD Gigabit SFP transceiver module, MMF/SMF Multimode & SingleMode

The Cisco GLC-LH-SMD Gigabit SFP transceiver module is designed to support both multimode and single-mode fibers. It is compatible with the IEEE 802.3z 1000BASE-LX standard and operates at a wavelength of 1300 nm.

When used with single-mode fiber, the GLC-LH-SMD can achieve link spans of up to 10 kilometers. It can also operate on multimode fibers with a maximum reach of 550 meters. However, when connecting to legacy multimode fiber, a mode conditioning patch cable is required to ensure proper coupling of the transmitter.

The GLC-LH-SMD module features an extended operating temperature range, allowing it to function in various environmental conditions. It also supports Digital Optical Monitoring (DOM), which provides real-time monitoring of key parameters such as optical power, temperature, and transceiver voltage.

For connectivity, the GLC-LH-SMD module utilizes dual LC/PC connectors, which are common in fiber optic networks. These connectors provide a reliable and efficient connection between the transceiver module and the network equipment.

Overall, the Cisco GLC-LH-SMD Gigabit SFP transceiver module is a versatile and high-performance solution for both multimode and single-mode fiber networks, offering extended reach, temperature tolerance, and monitoring capabilities.
