100BaseFX Connections: 
 
The Tx (transmit) port of device 1 
is connected to the Rx (receive) 
port of device 2, and the Rx 
(receive) port of device 1 to the Tx 
(transmit) port of device 2. 
 
 
 
 
 
 
 
 
Description
The media converter provides one channel for media conversion 
between 10/100BaseTX and 100BaseFX. It can be used as a stand-
alone device or with a standard 19 inch chassis as shown below. 
Features
 One-channel media conversion: 10/100BaseTX & 100BaseFX 
 Fiber media: 
Multi-mode fiber using SC or ST connectors 
Single-mode fiber using SC connectors 
 Auto negotiation of speed and duplex mode on TX port 
 Auto MDIX on TX port 
 DIP switch configuration for: 
 Link-fault-pass-through 
 Fixed speed 
 Half/full duplex 
 Store-and-forward mechanism 
 Non-blocking full wire-speed forwarding rate 
 Supports broadcast storm filtering 
 Back-pressure & IEEE802.3x compliant flow control 
Front panel status LEDs
 External AC to DC power adapter (included) 
 Used as a stand-alone device or with a chassis 
 Hot-swappable when used with a chassis
