Rollover or Touch for Expanded View. Scroll to Zoom.


Supporting distances up to 80km, the TC3705 10/100Base-T Ethernet Fiber Optic Switch provides one multimode or single mode optical port and four Ethernet ports.

The TC3705's modern switching technology eliminates the congestion problem inherent to the contention-oriented Ethernet CSMA/CD protocol and creates an efficient sub-divided switched LAN that provides full and transparent bandwidth for each segment. Optical connectors can be SC, ST or FC.

  • 4 Ethernet 10/100-Base Auto-Sensing UTP Ports
  • 1 Fiber Optic 100Base-FX Port
  • Distances up to 80km
  • Multimode or Single Mode(1300/1550nm)
  • Full or Half-Duplex Operation
  • Hardened Temperature (optional)
  • Exceeds Pertinent NEMA & Caltrans Traffic Control Specifications
  • Rackmount or Stand Alone


The TC3705 10/100 Ethernet Switch is a low cost and flexible bandwidth solution to efficiently handle the heavy traffic of local workgroups--- reducing the need of expensive routers that usually cater to the network backbone.
