The lead-in and tail fibre of type FX_AC_HQ_SM_SC_APC_5 from Softing IT Networks is a singlemode fibre cable with a length of 500 metres, specifically designed for demanding operating conditions. It features a special metal jacket that enhances mechanical stability and durability. The fibre is equipped with SC connectors, with one end fitted with SC PC and the other with SC APC, enabling compatible connections to various network devices. The designation Heavy Duty Line highlights the extremely rugged and robust construction, designed to withstand high mechanical stress in field operations.

Lead-in and tail fibre is used in measurement technology and network testing to simulate or analyse signal transmission over long distances. It serves as a reference cable for calibrating measuring instruments or evaluating the performance of optical networks under realistic conditions. Typical applications include industrial communication technology, installation of fibre optic networks, or maintenance of telecommunications infrastructure.

Singlemode fibre enables high bandwidth and low attenuation, making it suitable for long transmission distances. The special metal jacket protects the fibre against mechanical stresses such as pressure, tension, or bending, which is particularly advantageous in mobile or industrial applications. The construction is designed to provide high reliability even during frequent transportation and use in harsh environments.

SC connectors are standardised optical connectors used in many network applications. The combination of SC PC and SC APC at both ends of the fibre allows flexible connection to various devices, with SC APC featuring an angled polish surface that reduces reflections and thus improves signal quality. The use of APC connectors is common in applications requiring high optical signal integrity.

The fibre is classified as Heavy Duty Line, meaning it is designed for high mechanical stress. The special metal jacket ensures the fibre remains undamaged even under frequent bending, pulling, or pressure. This makes it particularly suitable for scenarios where the fibre is frequently transported, installed, or used in harsh environments.

The length of 500 metres allows simulation of long transmission paths, which is important during development, maintenance, or testing of fibre optic networks. The fibre is designed for use in industrial networking, installation of telecommunications infrastructure, or measurement technology, where high mechanical robustness and optical quality are required.

Compatibility and accessories include use with devices supporting SC connectors. The combination of SC PC and SC APC enables connection to various end devices, with the APC connector being especially suitable for applications requiring high signal quality. The fibre is not intended for direct use in end devices but serves as a test or reference cable in measurement technology.

Installation and mounting are typically performed by skilled personnel familiar with fibre optic technology. Due to its metal jacket and high mechanical stability, the fibre is suitable for use in harsh environments. Connections are made via SC connectors, which are standardised and ensure secure mechanical and optical connections.

In operation, the fibre provides high reliability and longevity, especially in applications requiring high mechanical stress. The special metal jacket protects the fibre from damage, extending its service life and reducing the need for maintenance. The fibre is designed for use in industrial communication technology and measurement technology, where high mechanical robustness and optical quality are required.
