General
Connector type	FC-SC

The product is a mode-transparent FC-SC multimode reference test cable from Softing IT Networks, type WX_AC_EF_MM_REFCORD_SC1. It serves as a standard connection cable for calibrating and validating network test equipment in the field of optical transmission technology, particularly for testing multimode fiber cables. The cable is designed as a duplex connection, featuring an FC connector at one end and an SC connector at the other. This combination enables the connection of different fiber cable types and connectors, which is advantageous when testing existing infrastructures or setting up new networks.

Reference test cable are essential in optical network metrology, as they serve as a known, calibrated connection to ensure the measurement accuracy of test equipment. The cable described here is specifically designed for multimode fibers, commonly used in local area networks (LAN) and data centers. The term mode-transparent means that the cable functions independently of the mode distribution in the fiber cable, ensuring broad applicability.

Functions and features in detail

The cable is designed as a duplex connection, meaning it contains two fibers, each transmitting data in opposite directions. This is typical for most optical networks, where one fiber is used for transmission and the other for reception. The connectors consist of an FC connector at one end and an SC connector at the other. These two connector types are widely used in industry: FC connectors are often found in permanently installed systems, while SC connectors are commonly used in switches, routers, and other network devices. This combination allows for flexible adaptation to existing infrastructures.

Technology explained simply

The term multimode refers to the type of fiber that transmits multiple light modes simultaneously. This enables higher bandwidth over short to medium distances, making it ideal for use in buildings, data centers, and local networks. The mode-transparent design means the cable functions independently of the specific mode distribution in the fiber cable, increasing the reliability of measurement results. Use as a reference cable requires high precision and reproducibility of optical properties, which is ensured by the cable’s specific construction and calibration.

Compatibility and accessories

The cable is specifically designed for use with multimode fiber cables and is suitable for calibrating network test equipment that operates on optical fibers. It can be used in combination with other test cables and equipment from the Softing IT Networks product range to create a consistent and verifiable measurement environment. Use in a duplex setup enables simultaneous testing of both transmission directions, increasing the efficiency of network analysis.

Installation and mounting

Installation of the reference test cable is performed by simply plugging the connectors into the corresponding ports on the test equipment or the fiber cables to be tested. No additional tools or mounting aids are required. The connectors are mechanically stable and provide a secure connection without additional fastening. The cable connection is suitable for use in laboratory environments as well as field testing.

Operational advantages

Using a mode-transparent reference test cable ensures high measurement accuracy and reproducibility. Since the cable serves as a calibration standard, deviations in signal transmission can be precisely detected and localized. The combination of FC and SC connectors expands application possibilities and reduces the need to stock multiple different reference cables. The duplex design enables efficient testing of both transmission directions in a single measurement process.
