Managed Fiber Optic Gigabit Ethernet Switch w/Self-Healing Ring (6TX + 2SX or 2LX)

Rollover or Touch for Expanded View. Scroll to Zoom.


Featuring a fast fault switchover of less than 38 msec., the TC3820 Redundant Gigabit Ethernet Switch brings maximum reliability to industrial fiber networks.

Ideal for mission critical fiber optic ring networks, the TC3820 Redundant Ring Gigabit Ethernet Switch maximizes reliability. If a fiber cable or device failure occurs, the data path automatically switches over within 38 msec. to the secondary path to maintain Ring network integrity.

  • Fault Recovery within 38ms
  • IEC 61850 & IEEE 1613 Compliant
  • Network Management (Web, Telnet, SNMP)
  • IEEE 802.3, 802.3u, 802.3x Compliant
  • 6 Ethernet 10/100-Base Auto-Sensing UTP Ports
  • 2 Fiber Optic 1000Base-SX/LX Ports
  • Standard Single Mode Distance of 50km (optional 100km)
  • Multi-mode or Single-mode (1300/1550nm)
  • 12VDC, Optional 24VDC, -48VDC, 125VDC or 115/230VAC
  • Industrial Hardened (optional)
  • Hi-Temp2 Version Exceeds NEMA & Caltrans Traffic Control Specs


The TC3820 is frequently used to interconnect Remote Programmable Logic Controllers (PLCs) in high bandwidth applications, such as interconnecting traffic control video cameras, that require multiple channels and the reliability of a Self healing Ring Topology.
