SFP transceiver for Gigabit links

The Cisco MGBLX1 is a hot-swappable SFP transceiver built for 1000Base-LX Gigabit Ethernet connections. It uses a 1310 nm wavelength over single-mode fiber with LC duplex connectors. The module supports link distances up to 10 km and fits standard SFP ports in switches and routers.

Suited for long single-mode runs.

This transceiver suits network builds that need gigabit speed over single-mode fiber spans up to 10 km. It will not operate on multimode fiber plants, nor does it support 10 Gigabit or faster Ethernet rates. Buyers needing shorter reach or multimode compatibility should choose a different module.

1310 nm single-mode wavelength defines reach

The 1310 nm wavelength on single-mode fiber is the specification that determines whether this transceiver matches the installed cabling and distance plan. Verify that the link uses single-mode fiber with LC duplex patching and that the required span falls within the 10 km rating before ordering.

Questions about this item

How do I install the Cisco MGBLX1 SFP module and what step is often missed?

Slide the module into an SFP port until it clicks, then insert the LC duplex patch cable; the step often missed is removing the dust caps from both the module and the cable ends before connecting.

What maintenance or replacement will the Cisco MGBLX1 need over time?

The LC connectors and fiber end-faces should be cleaned with a lint-free wipe and isopropyl alcohol whenever links are disconnected; no internal components require scheduled replacement.

What limit appears first when the Cisco MGBLX1 runs continuously at full load?

The optical budget for 1310 nm single-mode fiber over 10 km is the first constraint; sustained 1 Gbps traffic will hit distance or attenuation limits before the module overheats.
