FO Cables

Experience – Quality – Flexibility

Optimal Cable Design for Every Application

The extension of the R&M portfolio for FO networks with FO cables produced by the company increases our independence and speed of reaction. The quality customers expect of our cables, which until that point we had sourced from established, European cable manufacturers, is guaranteed. R&M is instrumental in driving on the development of CPR and fire load-optimized cables and sets standards.

Rodent Protection

A constant danger for laid WAN and campus cabling is the damage caused by rodent bites.

Critical zones for rodent infestation

Cables in shafts and canals are particularly at risk from rodent infestation.

Rodent attacks can also occur in less frequented cellars and in the transition areas from shafts and ducts into the building interior.

  1. Cable distribution in the building
  2. Cable distribution in the cellar
  3. Cables in trenches or pipes

Rodent Test

In one chamber of a two-part box, there is food, in the other water for the animals. After a few days, the passage between the two chambers is blocked by the cables to be tested. Damage to the cables is assessed after a fixed period of time.

The test equipment provokes repeated bite attacks against the cables.

Rodent-protected <=> Rodent-safe

Rodent safety requires steel-armored cables. In most applications, however, rodent protected cables are sufficient, as the motivation of the rodents is usually not sufficient not to look for alternatives to biting through.

Last Mile Cable

R&M offers specially designed cables for the last mile.

Self-supporting air cables (up to 100m)

Blow-in cables

  • FttH up to 4 fibers
  • FttB up to 12 fibers / 24 fibers

Fiber to the home / Minicore Cables

Minimized in cable diameter – maximized for the application width

  • Aerial drop
  • Fassade
  • In-house

Reaction to fire

  • CPR
  • Fire forwarding
  • Flue gas emission
  • Functional integrity
  • Fire load

CPR

R&M’s universal installation cables meet the Cca and Dca fire classes.

Indoor installation cables reach fire class B2ca.

Fire forwarding

Check the test methods used to determine fire propagation:

Dripping behavior of burning, molten plastic material
Self-extinguishing properties of the cable structure when laid horizontally and/or vertically

Flue gas emissions

Check the test methods for the determination of the flue gas emission:

Visual obstruction due to flue gases
Toxicity of the resulting flue gases

Functional integrity in the event of fire

The test methods for determining the functional integrity in the event of a fire check how long the data transmission functions in the event of a fire (standardized test setup).

The maintenance of the function does not necessarily have to be accompanied by a very good fire behavior of the cable.
