🔌 Cisco MGBSX1 SFP Transceiver: High-Speed Gigabit Ethernet (GbE) 1000BASE-SX Mini-GBIC Review

This fiber optic SFP adapter is compatible with the Cisco SG-200 and SG-300 Ethernet switches. It may be compatible with others, but it definitely works in those - I've tested it extensively. Another reviewer complained that this is a renamed part that doesn't work in Cisco switches. This is not a rebrand, this is a genuine Cisco part.

Seemingly simple device that actually does something very cool. For the user, however, it's as easy as peeling a pear – insert the fiber, connect to the switch, and that's it.

I give this product five stars because we have used it in a multimode fiber project so far, connecting IP cameras and to be honest the cameras are running all the time. We bought these for the Cisco SF 302-08MP 10/100 Max PoE 8-Port Switch. Remember that you need two fibers, one for the uplink and one for the downlink.

Exactly as described, works great, fits seamlessly into a Cisco switch. Mine comes with the "Cisco" trademark on a black label.
