10/100TX-FX Single Fiber Industrial Media Converter | 1-RJ45 Ethernet Port, 1-SC Fiber Port


The VERSITRON MF7275-2SFB Industrial Media Converter accepts a 10/100Base electrical input and converts this to a 100BaseFX optical output. This device can be house in rugged DIN rail or wall mountable enclosures. Well suited for harsh environments such as industrial security, system automation applications and intelligent transportation systems (ITS). Plug and Play installation. The MF7275-2SFB is used in conjunction with the MF7275-2SFA.
