The WX_AC_MANDREL from Softing IT Networks is a specific mandrel developed for testing multimode fibre optic cables. It serves as an aid for standardising cable testing, particularly when verifying the optical properties of multimode fibres. Using a mandrel ensures a reproducible and standard-compliant bending of the cable, enabling the determination of actual transmission characteristics under realistic conditions. This is especially important during the installation and maintenance of fibre optic networks, where connection quality is critical for the overall system performance.

Applications

The mandrel is primarily used in the field of fibre optic network installation and testing. It is suitable for testing multimode fibre optic cables used in local area networks (LAN), data centres, or other IT infrastructures. The application is performed in conjunction with network test devices that measure optical parameters such as attenuation or reflection. Using a mandrel allows testing cable quality under defined bend radii, which is essential for compliance with standards such as ISO/IEC 11801 or TIA-568.

Functions and Equipment in Detail

The mandrel is designed to enable a defined bending of the fibre optic cable, ensuring the bend radius is precisely maintained. This is necessary to ensure that measurement results are not distorted by uncontrolled bends or mechanical stress. The shape and dimensions of the mandrel are designed to meet the requirements of common standards for multimode fibres. The surface is smooth and non-slip, ensuring safe handling and even cable placement.

Technology Explained Simply

A mandrel is a cylindrical auxiliary device used during fibre optic cable testing to simulate a defined bend. For multimode fibres, bending is a critical factor as it affects optical attenuation and signal quality. The WX_AC_MANDREL ensures the cable is bent at a constant radius during measurement, guaranteeing comparability of results between different cables and tests. Using a mandrel is part of standardised testing procedures to ensure cables meet required technical specifications.

Compatibility and Accessories

The mandrel is specifically designed for multimode fibre optic cables and is used in conjunction with network test devices that measure optical parameters. It is not a standalone measuring device, but an auxiliary tool that contributes to the correct execution of tests. Compatibility is limited to multimode fibres; use with singlemode fibres is not intended.

Mounting and Installation

Mounting the mandrel involves simply wrapping the fibre optic cable around the cylindrical body. The cable is positioned to maintain the specified bend radius. No additional fastening or tools are required. Handling is manual, with the mandrel’s surface providing secure cable guidance. Installation is performed directly before measurement, without additional preparation.

Advantages in Operation

Using the WX_AC_MANDREL enables testing of the optical properties of multimode fibre optic cables under standardised conditions. This leads to reproducible measurement results, which are important for quality assurance and documentation of installations. The simple handling and specific design for multimode fibres ensure efficient and reliable testing. Compliance with standards is supported, which is particularly important in professional environments such as data centres or IT infrastructures.
