Featuring distances up to 80km*, the TC3212 10/100Base-T Ethernet Fiber Optic Converter provides a 100Base-FX port that combines Ethernet Switching with the benefits of fiber optic technology to boost network bandwidth, security and immunity from electro-magnetic Interference (EMI) and ground loops.
The TC3212 comes standard with one fiber port and one Ethernet copper auto-sensing switching port. The Ethernet port supports 10/100Base-T.
Specifically designed for long distances, the TC3212 can extend LAN segments up to 80km*. A one-fiber, bi-directional communication option is also available to maximize fiber optic cable usage. Seven diagnostic status LEDs are provided:

     “PWR”.......... DC Power Supply Indicator
     “VCC”........... VCC Voltage Indicator

     “Link/Act”...... Link and Activities Indicator
     “SDET”......... Signal Detect

     “Lnk/Act”...... Link and Activities Indicator
     “Speed”........ Indicate Speed 10M or 100M
     “Duplex”....... Indicate full duplex or half duplex

The TC3212 works with all popular sizes of single mode and multimode fiber optic cable. Fiber optic connectors are ST, FC or SC. Electrical connector is RJ-45 Female. Power is 12VDC, 24VDC, -48VDC or 115/230VAC with an external power cube. The standard operating temperature is
0°C to 70°C.
