Cisco GLC-LH-SMD;Cisco GLC-LH-SMD Gigabit SFP transceiver module, MMF/SMF Multimode & SIngleModeThe Cisco GLC-LH-SMD Gigabit SFP transceiver module is designed to support both multimode and single-mode fibres. It is compatible with the IEEE 802.3z 1000BASE-LX standard and operates at a wavelength of 1300 nm.Compatibility: It is compatible with the IEEE 802.3z 1000BASE-LX standard, ensuring interoperability with various networking devices and equipment.Fibre Support: The module supports both multimode and single-mode fibres, making it versatile for different network environments.Reach: When used with single-mode fibre, the module can achieve link spans of up to 10 kilometres, enabling long-distance connections. On multimode fibres, it supports a maximum reach of 550 meters.Mode Conditioning: When connected to legacy multimode fibre, the transmitter should be coupled through a mode conditioning patch cable to ensure optimal performance.Wavelength: The module operates at a 1300-nanometre (nm) wavelength, which is commonly used for fibre optic transmission in the LX/LH range.Temperature Range: It features an extended operating temperature range, allowing it to operate reliably in varying environmental conditions.The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fibre-optic link spans of up to 10 km and up to 550 m on any multimode fibres. When used over legacy multimode fibre type, the transmitter should be coupled through a mode conditioning patch cable. 1300-nm wavelength, extended operating temperature range and DOM support, dual LC/PC connector.Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (multimode and single-mode fiber) is 6.5 feet (2 m).Cisco GLC-LH-SMD SpecificationSFP Port Cabling SpecificationsProductWavelength (nm)Fiber TypeCore Size (μm)Modal Bandwidth (MHz* Km)***Operating Distance (m)1000BASE-SX850MMF62.5160 (FDDI-grade)220 (722 ft)62.5200 (OM1)275 (902 ft)50400 (400/400)500 (1,640 ft)50500 (OM2)550 (1,804 ft)502000 (OM3)1000 (3281 ft)1000BASE-LX/LH1310MMF*62.5500550 (1,804 ft)50400550 (1,804 ft)50500550 (1,804 ft)SMF-**–10,000 (32,821 ft)1000BASE-EX1310SMF-**–40,000 (131,234 ft)1000BASE-ZX(GLC-ZX-SMD)1550SMF––Approximately 70 km depending on link loss1000BASE-BX-U1310SMF-**–10,000 (32,821 ft)1000BASE-BX-D1490SMF-**–10,000 (32,821 ft)
