    TC3020 Series
     TC3021  20 bps to 1 Mbps
     TC3022  1 Mbps to 10 Mbps


Supporting data rates from 20 bps to 10 Mbps, the TC3020 Mode Converter Series convert, regenerate or extend 850nm, 1300nm or 1550nm wavelengths optical signals to distances up to 30 km*.

The TC3021 supports "Bursty or Continuous" data rates from 20 bps to 1 Mbps.  It requires units at both ends and converts multimode to single mode, then back to multimode.  Must be used in pairs. (It will not convert single mode to multimode, then back to single mode).

The TC3022 supports  "Bursty or Continuous" data rates from 1 Mbps to 10 Mbps.  It is a standalone converter (requires only one unit), and can convert from multimode to single mode, or vice versa. 

Eleven LEDs are provided for diagnostics, monitoring optic signals in both directions and indicating system status.  A Test Signal Generator is available to help technicians conduct various installation tests including fiber link verifications.  A Dry Contact Relay Alarm is also provided as a standard feature.

The TC3020 Series work with all popular types and sizes of fiber optic cable.  Fiber optic connectors are ST or FC type.  Power is 12VDC, optional 24VDC, -48VDC or 115/230VAC with an external power cube.  Hardened temperature versions (-20o to 70oC) are also available.
