Unmanaged Hardened Fast Ethernet Media Converter
(1) 100Base-TX Port + (1) 100Base-FX Port

E-100BTX-FX-05(HT) Series



The E-100BTX-FX-05(HT) is a Hardened Ethernet stand-alone media converter that provides an interface between 100Base-TX ports and 100Base-FX ports, allowing users to integrate fiber optic cabling into extreme 100Base-TX copper environments, by supporting an operating temperature range of -25°C to 65°C. Operating at Layer 1, the physical layer, data is passed through the converter at line speed, making it ideal for applications where low latency is essential.
