Choosing the right outdoor fibre cable for your project

Quick selection based on your environment and installation constraints.

1) Your priority: mechanical protection

Choose: Steel Armoured Cable
  • Runs in aggressive conduits / abrasion

View Steel Armoured Cables
Choose: Outdoor Cable
  • Standard outdoor use, robust installation
  • Controlled cable paths / fixings
  • Looking for the best performance/price ratio
  • Versatile installations
View Outdoor Cables

2) Your constraint: installation & connectors

Tight angles

Choose a flexible cable (min. radius 7.5 mm) for corner runs.

Clean job site

Choose the version with a reusable strap for easy storage and reuse.

Connectors

Check SC/LC & APC/UPC in the compatibility table (below).

Pro tip: if your cable will be handled frequently (temporary deployment, interventions), go for steel armoured + strap storage to keep the jacket intact for longer.

Decision matrix (30 seconds)

  • Conduit / abrasion / risks → Steel Armoured Cable
  • Standard outdoor / fixed installation → Outdoor Cable
  • Tight angles → flexible version (7.5 mm radius)
  • Need tidy storage → reusable strap
  • FTTH & bend → G657A2 fibre
  • APC/UPC & SC/LC choice → compatibility table

FAQ — Reinforced outdoor cables

Quick answers to the most frequent questions (choice, installation, performance).

1What is the difference between "Steel armoured" and "Outdoor cable"?
The steel armoured cable is designed for maximum mechanical protection (abrasion, shocks, torsion, heavy constraints). The outdoor cable is a robust and versatile solution for standard outdoor installations, with an excellent balance between protection, flexibility and cost.
2How to choose APC or UPC?
APC (green) is recommended when you want to minimise reflections (sensitive networks, long links, FTTH). UPC (blue) is common for standard links. Important: do not mix APC and UPC on the same connection. Use the compatibility table to confirm your model.
3Is the cable suitable for tight angles and corner runs?
Yes. The design favours flexibility and clean routing, with a stated minimum radius that can go down to 7.5 mm depending on the version and installation. For very tight angles, avoid unnecessary tension and secure the cable to maintain performance over the long term.
4Why is G657A2 fibre important for these cables?
G657A2 fibre is optimised for bend resistance, ideal for FTTH and runs requiring corner passages or constrained paths, while maintaining stable attenuation.
5Are the optical performances suitable for long installations?
Yes. The range targets stable transmission with low insertion loss (e.g. ≤0.2 dB depending on the version) and high return loss (e.g. ≥60 dB for some APC versions). For the exact choice, refer to the table (connectors, fibre type, OS2/OM2/OM3).
6What is the "reusable strap" for and when should it be chosen?
The reusable strap allows you to tidy up the cable after intervention, avoid knots and protect the jacket during transport. It is particularly useful for temporary deployments (job sites, events, field interventions) or for shared equipment.

Summary — what you gain

Resistance

Shielding & reinforced structure for harsh environments.

Stability

Low insertion loss and consistent optical performance.

Installation

Flexibility, easy separation, tidy storage thanks to the strap.
