Duplex Cable

DaRo Fibre Products are pleased to offer LEONI’s GigaLine® I-V(ZN)H 2x1 range of indoor fibre optic duplex cables. Duplex cables are primarily used in the production of fibre optic patch cords and jacketed pigtails.

Using either a tight-buffer or semi-tight buffer 600 or 900 micron fibre surrounded by aramid yarn strength members encompassed within a low smoke zero halogen (LSZH) cable sheath. The aramid yarn strength members provide a reinforced construction providing a flexible but rugged cable suitable for use in internal cabling or direct termination using fibre connector applications.

Single mode duplex cables are available with a yellow cable jacket; multi-mode 62.5/125 (OM1) and multi-mode 50/125 (OM2) are available with an orange jacket. Laser optimised multi-mode 50/125 (OM3) is available with an aqua cable jacket and laser optimised multi-mode 50/125 (OM4) is available with a heather violet cable jacket.

  • Cables are available in 1.8mm, 2.0mm, 2.4mm or 2.8mm diameters
  • Single mode available with G.652.D, G.657.A1, G.657.A2 or G.657.B3 fibre
