Signamax 065-1196SFPDR 10/100/1000 to 100/1000 SFP Media Converter 10/100/1000BaseT/TX to Dual-Rate 100Base or 1000Base SFP Media Converter. The Signamax 10/100/1000 to 100/1000 SFP Media Converters provides a flexible and intelligent solution for long distance connections between legacy 10BaseT and 100BaseTX networks and either 1000Base Gigabit Ethernet fiber or 100Base fiber networks. The built-in 10/100/1000 switch enables the fiber cable connection to operate at 1000 Mbps, while remaining completely 1000BaseSX/LX or 100BaseFX/BX standard-compliant for the fiber optic connection. The dual-rate fiber converter includes the ability to force the RJ-45 port to 100Base or 10Base full or half-duplex modes where required. The Link Fault Signaling provides a means of propagating a link drop on either port of the media converter to the other port, enabling a connected managed switch to see the link drop and respond to it using Spanning Tree Protocol or another recovery scheme.
