General
Plug connection	ST/PC-ST/PC

The product is a multimode test cable from Softing IT Networks, configured as an ST simplex connection with a length of 2 meters. It features ST/PC connectors at both ends, designed for secure and precise optical connections in network applications. The cable is primarily used as a test and diagnostic aid in the installation and maintenance of fiber optic networks, particularly in environments where multimode fibers are employed. Typical use cases include IT infrastructure, signal integrity checks, loss measurements, or fault diagnosis in fiber optic lines.

Multimode test cable enables the transmission of light signals over short to medium distances, with multimode technology transmitting multiple light modes simultaneously. This makes it particularly suitable for applications in local area networks (LAN) or data centers, where high bandwidths are required over short distances. The ST/PC connector is a widely used, mechanically stable, and easy-to-handle connector that provides a clean, flat polished surface (PC = Physical Contact) to minimize reflections and signal losses. The simplex configuration means the cable carries only one fiber core, which is sufficient for unidirectional measurements or connecting individual devices.

The length of 2 meters is standard for indoor use, such as in server rooms or enclosures. It allows flexible positioning of test equipment and provides sufficient reach for connecting to optical devices without becoming excessively long or cumbersome. The ST/PC connectors at both ends ensure a standardized and compatible connection with corresponding ports, guaranteeing interoperability with common test and network equipment.

The cable is specifically designed for testing purposes and is therefore typically not used as a permanent network connection, but rather as a temporary tool for diagnosis and quality assurance. It is intended for use in the maintenance, installation, and commissioning of fiber optic systems. In practice, it is often used in combination with optical power or loss measurement devices to verify the quality of fiber links.

The multimode technology offers higher light transmission capacity compared to singlemode, although with reduced range. This makes it ideal for applications within buildings or between servers in a data center. The ST connector is particularly robust and easy to install, making it common in many industrial and IT environments. The simplex configuration is suitable for applications where only one direction of signal transmission is required, for example, when measuring received power at one end of a fiber link.

The cable is typically used without additional tools, as the connectors are simply plugged into the ports. Installation is therefore quick and straightforward, requiring no special mounting aids or tools. Use is therefore restricted to enclosed, dry environments such as server rooms or enclosures.

The test function of the cable lies in its ability to transmit optical signals over a defined distance, allowing signal quality, losses, and reflections to be measured. This is critical for quality assurance during the installation of fiber optic networks. The ST/PC connectors ensure a clean, low-reflection connection, which increases the accuracy of measurement results. The 2-meter length provides sufficient flexibility for connecting to test equipment and allows for flexible positioning without excessive cable runs.

The cable is order-specific and non-cancellable, meaning it is manufactured after order placement and cannot be returned. This is typical for specific, custom-made components that are not stocked. Use is exclusively for technical applications, particularly in fiber optic network technology, and is not intended for general end consumers.
