Hot-Swappable SFP for Gigabit Ethernet

The AddOn GLC-LH-SM-AO is a 1-port 1000Base-LX SFP transceiver designed for data networking. It plugs directly into a Gigabit Ethernet slot to link the port with a fiber-optic network. The module is hot-swappable, allowing installation or removal without powering down the switch. It targets network administrators expanding or repairing fiber links on compatible Cisco platforms.

Factory-Loaded OEM Configuration Data

Each transceiver arrives factory loaded with OEM specific configuration data required for networking compliance. This ensures the module initializes and performs identically to original Cisco transceivers. The LC duplex interface supports 1000Base-LX/LH connectivity over single-mode fiber. Physical dimensions measure 0.3 height by 0.5 width by 2.2 depth, fitting standard SFP cages.

Verify Switch Platform Before Ordering

Compatibility is limited to specific Cisco platforms including the ME 3400 series, Catalyst 4500 series with WS-X4013+10GE, and Catalyst 6500 series with WS-SUP720, WS-X6724-SFP or WS-X6748-SFP modules. Buyers must confirm their exact switch model and line card against this list. The module will not function in switches or line cards not listed here.

Questions about this item

What does the 1000Base-LX interface cap in practice?

The 1000Base-LX interface runs at 1000 Mbps over single-mode fiber with an LC duplex connector.

What physical space does the SFP need to fit?

The module measures .3 height by .5 width by 2.2 depth and plugs into a standard SFP slot.

How is the transceiver installed and what step is often missed?

Insert the hot-swappable SFP into a Gigabit Ethernet slot until it clicks; the step people miss is verifying the OEM configuration data loads so the link initializes identically to the original transceiver.
