TRENDnet's TFC-110 series Fiber Media Converter transforms 10/100 Base TX UTP/STP media to 100 Base FX media & vice versa. The 10/100 Base TX port auto-senses 10 or 100 Mbps connection speed, auto-negotiates half-/full-duplex mode, & auto-selects MDI-X / MDI-II media type. The fiber connection can be multi-mode SC, MT-RJ, or single-mode SC Connector & it has a slide-switch for selecting half- or full-duplex mode. This converter will give your Switch/ Hub the ability to interface with fiber connection over a distance up to 75 km. With the optional 16-slot EIA-19" rack-mount chassis, the TFC series converters are the perfect solutions for various fiber media conversions for your network.
