MRB 50-Pair IDC Block

Model: MRB-50-M03-T01-A02-XXX-(X)-(XX)


The modular 50-pair untailed or tailed blocks can be stacked vertically or horizontally, enabling assembly of cross-connect fields with any required pair counts. Optional fanning strips can be clipped to the blocks to create wire-guide borders for trouble-free routing and management of jumper wires. Customized blocks are available potted and tailed to length.


  • Insulation Displacement Connector (IDC) eliminate the need to strip wires, resulting in faster on-site connections
  • Transparent wire receivers allow visual confirmation of proper wire insertion and IDC contact before a connection is made
  • Tool-less operation: finger-operated receivers and audible latch-down action eliminate problems of breakage through improper use of tools
  • High Viscosity Compound (HVC) environmental encapsulation eliminates corrosion, enabling IDCs to function in high-humidity environments
  • "Quiet Front" design and easy test access eliminate the need for disconnection during circuit testing
