Guide to installation and handling

• When laying and installing optical fibre cables it is vitally important not to exceed the specified values set for pulling
tension, bending radii and temperature. The installation methods have to be in accordance with the common standards.

• The
To ease insertion into tubes by means of compressed air or pulling wire, certified lubricants (e.g. paraffin) may be used.
use of soap or similar substances as lubricants is strictly prohibited.

• ItTheis advisable
jelly filling inside the tubes can be removed using a tissue soaked in turpentine.

• to cap the cable-ends during storage.

Options

• available
Non-standard cable constructions, colours, details and/or additional information regarding specifications are
on request.
