The lead-in and tail fiber of type FX_AC_HQ_SM_SC_APC_3 from Softing IT Networks is a singlemode fiber cable with a length of 300 meters, specifically designed for use in demanding environments. It features a special metal jacket, making it extremely durable and robust — a version referred to as Heavy Duty Line. The fiber is equipped with SC connectors, with one end featuring SC PC and the other SC APC, enabling compatible connections to various network components. This construction is suitable for use in industrial or outdoor installations where high mechanical stress and environmental influences occur.

Applications

The fiber is primarily used as a lead-in or tail fiber in measurement technology, especially during the installation and maintenance of fiber optic networks. It serves as a connecting element between measuring devices and the cable under test to analyze optical signal transmission. Due to its robust construction, it is particularly suitable for use in industrial environments, maintenance of telecommunication infrastructure, or fiber optic installations where high mechanical stability and longevity are required.

Functions and Equipment in Detail

The fiber is designed as a singlemode cable, meaning it is optimized for transmitting light signals with high bandwidth and low attenuation over long distances. The use of SC connectors ensures a standardized and secure connection. The SC APC connector (Angled Physical Contact) reduces reflections at the connection point, which is particularly advantageous for sensitive measurement applications. The special metal jacket protects the fiber against mechanical stresses such as pressure, tension, and bending, extending the cable’s lifespan and increasing operational reliability.

Technology Explained Simply

The term Heavy Duty Line describes the fiber’s exceptional mechanical strength. The metal jacket acts as a protective layer, shielding the sensitive glass fiber from external influences such as cable damage, friction, or mechanical stress. The 300-meter length allows use in large installations or for connecting remote measurement points. Singlemode technology is suitable for high-speed and long-distance transmissions, as it transmits only one light mode, resulting in lower signal losses. The combination of SC PC and SC APC connectors allows flexible adaptation to different devices and systems.

Compatibility and Accessories

The fiber is compatible with measuring devices and network components that support SC connectors. The use of SC APC connectors makes it particularly suitable for optical measurement systems where minimal reflections at the connection point are required. The fiber can be used in combination with other components of the Heavy Duty Line to ensure a consistent and robust cabling solution.

Installation and Mounting

Installation is performed by simply plugging the SC connectors into the corresponding ports of measuring devices or network components. The robust metal jacket facilitates handling and protects the fiber during installation. No special tools or additional mounting aids are required. The fiber is designed for industrial environments, with its mechanical durability and 300-meter length enabling installation in large-scale facilities.

Operational Advantages

The fiber offers high mechanical stability and longevity, reducing maintenance intervals and increasing operational safety. The use of SC APC connectors minimizes reflections and improves measurement accuracy. Singlemode technology ensures high signal quality over the entire 300-meter length. The special metal jacket protects the fiber against mechanical damage, which is particularly beneficial in harsh environments. The fiber is therefore suitable for applications where reliability and long-term stability are paramount.
