The product is a mode-transparent FC-SC multimode reference test cable, manufactured by Softing IT Networks, type WX_AC_EF_MM_REFCORD_SC2. It serves as a reference cable for testing and calibration of network test equipment in the field of fiber optic communication. The cable is specifically designed for use in duplex systems and is delivered as 1 pair, consisting of two individual SC-SC test cables. This configuration enables precise testing of fiber optic connections, particularly for measuring insertion loss and reflections, which are critical for the quality of optical transmission.

Reference cable for network testers

A reference cable is a calibrated cable that serves as a standard for the calibration and validation of measuring instruments. In this model, it is a mode-transparent multimode cable, meaning that it provides a constant and reproducible optical performance regardless of the mode structure used (e.g. OM1, OM2, OM3, OM4). This is particularly important to ensure that measurement results are comparable across different systems. The use of a reference cable ensures that measuring instruments are correctly calibrated and that no systematic errors are introduced into the measurement.

The two ends of the cable are fitted with SC connectors, a standard connector system for fiber optic cables, widely used in data transmission systems. The SC connector is known for its mechanical stability and ease of handling. The cable is configured as a duplex cable, meaning it contains two separate fiber optic conductors, each fitted with an SC connector. This configuration is typical for bidirectional data transmission, as commonly used in Ethernet networks or other fiber optic networks.

The mode-transparent design of the cable means that it delivers a constant optical performance regardless of the specific mode structure of the multimode fiber optic cable being used (e.g. OM1, OM2, OM3, OM4). This is essential to ensure that measurement results are comparable across different fiber optic types. The mode-transparent property is achieved through the cable’s special construction, which ensures an even distribution of light modes regardless of the input mode structure.

The cable is primarily used in network testing, particularly for the calibration and validation of fiber optic test equipment. It serves as a reference to check the accuracy of measuring instruments that measure insertion loss, back reflections, or other optical parameters. The use of a mode-transparent reference cable ensures that measurement results are not influenced by the specific mode structure of the cable, but reflect only the characteristics of the connection segment being tested.

The cable is designed for use with network test equipment that checks fiber optic connections. It is specifically designed for multimode systems and can be used with devices that support SC connectors. Compatibility with specific devices or systems is not explicitly stated, but the standardization of the SC connector and multimode technology ensures broad applicability in the IT and telecommunications industry.

Installation of the reference cable is performed by simply plugging the SC connectors into the corresponding ports of the test equipment or the connections being tested. It requires no special mounting or tools. Handling is straightforward, as the SC connectors feature a clear mechanical locking mechanism that prevents accidental disconnection. The cable is suitable for use in laboratory and field environments, although no specific environmental conditions such as temperature or humidity are specified.

The use of a mode-transparent reference cable offers the advantages of high measurement accuracy and reproducibility. Since the optical properties are independent of the mode structure, measurement results can be directly compared regardless of which multimode cable is used in the network. This reduces sources of error and increases the reliability of network diagnostics. The standardization of the SC connector facilitates integration into existing test environments.
