Gigabit networking is the upper echelon of performance, especially compared to 10 and 100 Mbps connections. The MGBSX1 Gigabit SX Mini-GBIC SFP Transceiver offers the ability to tap into faster networking speeds using fiber optic cabling. Installing the module is as easy as sliding it into an accompanying port on a compatible Cisco switch. Please note: networking components such as switches, routers, UPS and wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance
