Optronics Cabling Overview

 

Optronics Structured Cabling

 

Multi Loose Tube Internal/External Cable

Muti Loose Tube Internal/External Cable

36~144 Fibres

Description

  • These dielectric Multi-Loose Tube cables are constructed of multiple colour coded loose tubes, each containing 12 colour coded 250µm coated fibres and gel, and the requisite number of filler tubes, stranded around a central strength member. These are bound by water blocking tape and then E-Glass yarn strength members, which also provide rodent resistance. The whole assembly is then enclosed in a black LSZH outer jacket, meeting IEC fire performance requirements.

  • Fibre counts of 36 thru’ 144 are available in all four standard specifications – OM1, OM2, OM3 and OS1 fibres.

Applications

  • Subway tunnels to transmit video, voice and data signals for traffic control, communications and security applications

  • Lightweight, flexible, small diameter ideal for duct and lashed aerial use

  • Interbuilding, computer and communication links

Features

  • E-Glass strength members

  • providing rodent resistance and moisture protection

  • All dielectric design is for use in close proximity to high voltage lines and provides lightning immunity

  • Colour coded fibres and buffer tubes for easy identification

  • 2700N rated pulling tension enables long pulls without concern for fibre damage

  • Ripcord for easy jacket removal

  • LSZH jacket for internal use

  • Black jacket as standard for UV resistance
