Cisco GLC-LH-SMD= 1000BASE-LX/LH SFP MMF/SMF Gigabit Interface Converter

Cost-effective Small Form-factor Pluggable (SFP) transceivers for Gigabit Ethernet applications

Product overview

The industry-standard Cisco® Small Form-Factor Pluggable (SFP) Gigabit Interface Converter (Figure 1) links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot. Optical and copper models can be used on a wide variety of Cisco products and intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.

Features and benefits

• Hot swappable to maximize uptime and simplify serviceability
• Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate”
• Robust design for enhanced reliability
• Supports Digital Optical Monitoring (DOM) capability

1000BASE-LX/LH SFP for both multimode and single-mode fibers

The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable.
