Extend 2 T1 Circuits (MPLS, PRI, or DATA) Over Fiber, Line Powered​

Industrial Media Converters - 2 Channel T1 Fiber Mux
2 Channel T1 Fiber Mux
This 2 Channel T1 Din unit was design to meet NEBS Level 3 requirements and built to last in harsh environments. This product is unique in its ability to be line powered by a NIU. Line (also known as Span or Loop) powering removes the need for expensive powering arrangements when the unit is used in remote locations for High Voltage Isolation or T1 Demark Extensions. This unit is compatible with any T1 circuit delivered in North America, It supports DATA, PRI, & MPLS T1 circuits and is a cost effective solution where space is a premium and a small foot print is required.


  • Applications for critical, high voltage, remote or unmanned locations that must remain operating 24/7/365
  • Simplex 60mA line powered on the drop side from the T-1 span or HDSL NIU/RT unit, eliminating costly external power arrangements
  • Dual power capable, line or 24-56VDC
  • Environmentally hardened to operate in -40°F to +158°F (-40°C to +70°C) environments
  • Accommodates up to two incoming T-1 4 wire copper lines over one fiber pair
  • Ideal for T-1 applications where available fiber strands, enclosures or mounting space are limited
  • The same module may be used at either end of the fiber system, simplifying spares and ordering
  • Compatible with the 2 Channel T1 Fiber Link Card, allowing for mix-and-match installation options at each end
  • Will operate from any HDSL-1, HDSL-2 or HDSL-4 NIU/RT signal
  • Loop back features with independent channel testing
  • Provides simultaneous multiplexing and de-multiplexing of two asynchronous T-1 channels
  • Frame integrity LED and remote T1 channel fault LEDs
  • Available in Single or Multimode
  • Available with ST or SC Connectors
  • Convenient DIN Rail or Wall Mount
  • Limited Lifetime Warranty
