Complete Connects Low Loss patch cords are used to connect high speed data and legacy networks at speeds of up to 10Gbp/s. Our multimode patch cords are manufactured for internal use and are created using LSZH jacketing which conforms to all current IEC, EIA TIA or Telcordia  standards. The Low Loss patch cords are terminated with high performance singlemode ferrules to a UPC standard for optimal concentricity and alignment resulting in a significant optical improvement over standard multimodepatch cables. Each patch cords high quality connectors are terminated directly into each fibre core.

Complete Connects Low Loss patch cords all have machine polished connectors for consistent high finish and are polished on a multi-stage machine process to give the best insertion and return losses. The Low Loss patch cords are also made with a tight bend radius and quick release tabs for easy use and installation.

Applications for the Low Loss patch cords include 10G and 25G patching and 10G and 25G direct connect.

Bespoke options for the cords include choice of fibre colour, length and being pre-labelled.
