| The D-Link DFE-855 is a Fast Ethernet media converter that translates transmission signals from a twisted-pair 100BASE-TX cable to 100BASE-FX fiber optic cable. It expands network data transmission distances beyond the 100 meter limitation of copper wire to a maximum of two kilometers by using fiber optic cable in full duplex. The DFE-855 provides auto-sensing detection of full duplex or half duplex signaling. It has easy-to-read diagnostic LED's for continuos status reports on network speed, duplex media access control connection, and network traffic. The DFE-855 uses standard RJ-45 UTP/STP and SC fiber optic connectors and is IEEE 802.3u 100BASE-TX/FX compliant and operates with all devices that adhere to this standard. |
