Switches that convert between optical and network ports

Also known as a Fiber Media Converter, this versatile device bridges the gap between fiber optic and copper-based Ethernet networks. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level. VERSITRON manufactures a wide range of fiber optic switches that provide links for your 10Base, 100Base, 1000Base Gigabit, and 10 Gigabit networks simultaneously. They can function as core, aggregation, and access devices on campus networks and connect to upstream and downstream devices. OmniConverter 10/100/1000 and 10G Compact Ethernet Switches enable distance extension to multiple network edge devices such as workstations, IP cameras and Wi-Fi routers.
