Cisco 1000base-lx/lh Sfp Transceiver Module Mmf/smf 1310nm Dom (GLC-LH-SMD)

Cisco 1000base-lx/lh Sfp Transceiver Module Mmf/smf 1310nm Dom (GLC-LH-SMD)

Available in New & Refurbished

Cisco's industry-standard SFP is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of IEEE 802.3z- compliant 1000Base SX, 1000Base LX/LH, or 1000BaseZX interfaces on a port-by-port basis.

The Cisco GLC-LH-SM fully complies with the IEEE 802.3z 1000Base LX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard.

Features and Benefits

• Hot Swappable to Maximise Uptime and 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 Fibres

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.

100/1000BASE-LX SFP for Long-Reach Single-Mode Fibers

The dual-rate 100M/1G 10Km SFP is interoperable with the IEEE 100BASE-LX and 1000BASE-LX/LH standards.

The GLC-GE-DR-LX SFP also supports digital optical monitoring (DOM) functions according to the industry-standard SFF-8472 multisource agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

SFP Operation at 100M

The GLC-GE-DR-LX SFP can interoperate with other 100M SFPs/interfaces as long as those are based on 100BASE-LX10 standard. A 5dB attenuator is needed on the path of dual-rate SFP Tx and 100BASE-LX10 interface Rx. No attenuator is needed on the other fiber strand.

SFP Operation at 1G

The GLC-GE-DR-LX SFP can interoperate with other 1G SFPs/interfaces as long as those are based on 1000BASE-LX/LH standard. No attenuator is needed in any fibre strand.
