Cisco MGBSX1 Gigabit Ethernet 1000BASE-SX SFP Mini-GBIC Transceiver – 850nm Multimode, LC Connector

The Cisco MGBSX1 is a 1000BASE-SX Gigabit Ethernet SFP mini-GBIC transceiver for Cisco Small Business switches. It runs Gigabit links over 850nm multimode fiber up to 550 metres with a duplex LC connector, suiting IT teams linking wiring closets and floors.

Genuine Cisco Gigabit fiber uplinks for small business networks.

Extending Gigabit Links Beyond Copper Limits

Copper Ethernet stops at 100 metres and is sensitive to electrical interference. Linking wiring closets, floors or adjacent rooms often needs fiber.

The MGBSX1 plugs into SFP ports on Cisco Small Business switches and runs Gigabit Ethernet over multimode fiber up to 550 metres, recognised natively by the switch.

Hot-Swappable SFP Form Factor

Insert or replace the module while the switch is running to add uplinks without downtime.

Native Cisco Compatibility

As a genuine Cisco module, it avoids third-party optic warnings on supported switches.
