Signamax 065-1120 10/100BaseT/TX to 100BaseFX Media Converter SC/SM, 15 km Span

Reference#: 73941
Item#: SG-065-1120


The Signamax 10/100 to 100FX Media Converters with Link Fault Signaling provides the means for an SNMP managed switch to recognize a failure on a fiber channel or twisted-pair connection, enabling the switch to automatically route to a backup path if the connected switch is equipped with Spanning Tree Algorithm. This intelligence maximizes the power of managed switches and enables failsafe design solutions for complex networks. The 065-1120 media converters also extend the maximum singlemode fiber distance, spanning up to 15km (9.3 miles).

The built-in 10/100 switch enables the fiber cable connection to operate at 100 Mbps connected to either a 10BaseT or a 100BaseTX network, while remaining completely 100BaseFX standard-compliant. Fiber connection can also operate in full duplex mode whether the RJ-45 port is connected to a full duplex switch or a half duplex hub, with the built-in switch providing the network segmentation that permits the maximum fiber distance.


• DIP switch configuration for link fault signalling, fiber auto/force mode, and SFP speed

• Built-In 10/100BaseT/TX Switch utilizes store-and-forward architecture

• Supports wall mounting, DIN-rail mounting or use with media converter rack mount chassis

• LEDs for functions, links, and activity
