Rollover or Touch for Expanded View. Scroll to Zoom.


The TC3240 4-port Switching/Bridging Fiber Optic Ethernet Media Converter converts or connects UTP (10/100Base-TX) networks to Fiber Optic (100Base-FX) networks.

The TC3240 includes a built-in switch that enables distances up to 100km without additional hardware (e.g. Switch or Router). Security features include allowing up to four different IP address aliases, manageable privilege levels for users and password protection. VLAN is also implemented for secure access.

  • 3 Ports 10/100 Base-T
  • 1 Port 100FX: Multimode (1300nm) or Single Mode (1300/1550nm)
  • Rate Control and VLAN (IEEE 802.1Q)
  • Network Management (Web, SNMP, Telnet)
  • Remote Firmware Upgrade
  • Extreme Temperature version exceeds NEMA & CALTRANS specs (-40°C to 80°C)
  • One Fiber Bi-Directional Optic Optional
  • Configuration Save and Load
  • Power Monitoring


The TC3240 is frequently used by Data Service Providers to control the bandwidth they offer to customers. It is also used for its ability to transmit over long distances (100km or farther) without connecting to additional hardware, e.g. a Switch or Repeater. The Hardened Temperature option enables it to be used in extreme environments.
