Fiber Optic Cables & Microducts

Aerial, duct and air-blown routes — pick the construction that matches your span, fiber count and budget.

The four constructions

Match the cable to the route

Each cut-away below shows how the cable is built. Choose by where it runs and how you plan to grow the network.

ADSS all-dielectric self-supporting cable cross-section

ADSS — All-Dielectric Self-Supporting

Aerial feeder spans, no messenger wire

Aerial spans without the messenger wire. The fiber rides on a dielectric strength member instead of a steel sling, so there is nothing to bond to the pole and nothing to rust. Reaches 12–144 fibers over 100–400 m spans — the workhorse for neighborhood feeder runs.

  • Optical fiber
  • Loose tube
  • Tube filling compound
  • Central strength member
  • Aramid yarn
  • Inner sheath
  • Water-blocking material
  • PE outer sheath
ASU ADSS 0+3 lightweight aerial drop cable cross-section

ASU (ADSS 0+3)

Lightweight aerial drops

A slim self-supporting drop that pairs three steel strength wires with a single loose tube. Light enough to run by hand between poles and buildings, which makes short-span subscriber drops fast, inexpensive and easy to tension.

  • Optical fiber
  • Loose tube
  • Filling compound
  • 3 × steel strength wires
  • PE sheath
GYXTC8S central tube figure-8 optical cable cross-section

GYXTC8S Figure-8

One cable, its own messenger

A figure-8 construction that fuses the optical unit and a steel messenger into one jacket. Crews install it in a single pass along aerial access routes, and the messenger carries the mechanical load so the fiber core never has to.

  • Central loose tube
  • Optical fiber
  • Filling compound
  • Steel messenger
  • PE sheath
GYCFHTY air-blown loose tube micro cable cross-section

GYCFHTY Air-Blown Micro Cable

Blow fiber now, decide capacity later

Built to be air-blown into 10/8 mm microduct after the duct is already in the ground. Start with the duct, add cable when subscribers arrive, and scale up to 288 fibers — without reopening the trench. Sections run 500–1,500 m per blow.

  • Optical fiber
  • Micro loose tubes
  • Aramid yarn
  • Water-blocking yarn
  • Thin PE sheath

Cut-aways are illustrative of construction, not to scale. Typical test values are subject to project specification; full parameter tables are available on request.
