Protective tubes, plastic tubes and reinforced tubes

Mechanical protection for optical fibers

While optical fibers are fairly durable, they often cannot withstand all possible environmental conditions – especially those in harsh industrial surroundings. This is where additional protection becomes necessary, which prevents the fibers from being damaged or coming into contact with substances that could adversely affect their transmission performance or longevity. Protective tubes are available for various optical fiber assemblies, to protect against damage from longitudinal and transverse forces, and various environmental factors. Plastic tubes and reinforced tubes are used for the direct assembly of multi-fiber loose tube cables with fanout elements for mechanical protection of the fibers. To ensure proper handling of cables during installation and maintenance work, the application of warning marks is very helpful and easily achieved.

Your advantages at a glance

Appropriate protection for almost any optical assembly requirement

  • Against damage from longitudinal and transverse forces
  • Against various environmental factors: flame-retardant, rodent protection, limiting the bending radius, vacuum-compatible, high-/low-temperature resistant, with strain relief, non-crushable, and many more
  • For proper handling during installation and maintenance work (e.g. colored markings and warning notices)

Further information

We offer these items only as part of an assembly. Only in this way can we ensure that the connection technology is compatible with the protection and that the assembly really does perform as specified. Our Product Engineering unit, company-internal assembly, and our long experience as fiber optics experts ensure the compatibility of all components and the fulfilment of all requirements for the final assembled product.
