Subunitized Premise Microcore fiber optic cables
Subunitized Premise Microcore fiber optic cables

Sub-Unitized Premise MicroCore® Cable


  • Plenum NFPA 262 rated, Riser UL 1666 and UL 1685
  • Tested to meet or exceed EIA/TIA 568-B3, Telcordia GR-409-CORE and ANSI/ICEA S-83-586
  • LSZH performance verified to IEC 60754-2, 61034-2 and 60332-3-24
  • Flexible dielectric FRP central strength member in four position, 24 fiber designs and higher
  • High performance fluoropolymer, outer PVC, LSZH outer sheath
  • No preferential bend typically found in stacked ribbon designs
  • Small diameter/superior bend performance
  • All aramid tensile strength members within sub-units
  • Sub-units are suitable for direct termination with round boot MTP
  • Compliant to Directive 2002/95/EC (RoHS)


  • In-building cable runs where space is a premium
  • Trunk applications where flexibility and small required bend radius are needed to route cable
  • High density cable areas like Data Centers and Central Offices
  • Lower cost cable runs where easy handling of tight buffered fibers not needed because cable will be spliced to factory terminated pigtails
  • Horizontal and Vertical Trunk cables where MTP can be directly terminated on subunits

Product Description

Sub-Unitized Premise MicroCore® fiber optic cables are ideal for 12-144 fiber high performance premise installations where space is a premium.  The round cross-sectional building blocks combine to provide a tight package, while enabling high density architecture.  Each 12-fiber sub-unit consists of 250µm colored fibers and aramid strength members enclosed by a high performance jacket.  Cable constructions are available supportin the stringent safety requirements of UL 1666, UL 1685, NFPA-262 as well as International LSZH standards.  Riser rated cabling meets the recently revised Vertical Trunk cabling standards of Telcordia GR-409 reuiring an increased level of Tensile Strength to withstand floor-floor installations.  This architecture is increasing in popularity as DataCenter operators work to utilize available floor-space in dense urban centers.  The sub-units independently meet the interconnect standards of Telcordia GR-409 and are suitable for independent routing within well-maintained fiber management systems.
