General
Connector type	FC-LC

This product is a mode-transparent FC-LC reference test cable from Softing IT Networks, type WX_AC_EF_MM_REFCORD_FCLC. It is a simplex test cable specifically developed for the calibration and validation of optical measuring instruments in the field of fiber optic communication. The cable serves as a reference standard to ensure the accuracy of measurements on fiber optic connections, particularly when checking insertion losses and back reflections. It is designed for use in laboratory environments as well as for technical inspections in the field, where a reproducible and reliable reference is required.

Mode transparency is a central feature of this test cable. This means the cable functions independently of the mode type used (singlemode or multimode), making it universally applicable. The mode-transparent property allows the cable to be used with various fiber optic systems without requiring adjustments or changes to the test equipment. This reduces effort during testing and increases efficiency during calibration.

FC-LC connector describes the two connectors attached to the cable. One end features an FC connector, while the other end has an LC connector. This combination is typical for applications where different connector types must be connected within a network. The connectors are designed for a secure and stable optical connection, with mechanical fit and optical alignment ensuring low losses. The use of FC and LC enables connection to a wide range of devices, such as network switches, measuring instruments, or fiber optic distribution boxes.

Reference test cable is the technical term for a cable used as a calibration standard. Unlike a regular connection cable, it is not used for data transmission but for calibrating measuring instruments. The precise optical characteristic of the cable is recorded during manufacturing and serves as a reference value. This allows measuring instruments to be calibrated based on this cable, ensuring their readings are accurate. This is particularly important in quality assurance and the maintenance of fiber optic networks.

Simplex configuration means the cable contains only one fiber optic conductor. This is the standard configuration for test cables, as it enables the measurement of individual optical parameters without interference from a second conductor. The simplex structure simplifies the analysis of losses and reflections and is therefore ideal for precise measurements.

It is delivered as a single product without additional accessories. Use is immediate after unpacking, with no additional mounting or preparation steps required. Installation is achieved by simply plugging it into the corresponding connectors of measuring instruments or network components.

The application areas include calibration of OTDRs (Optical Time Domain Reflectometers), fiber optic measuring instruments, and validation of fiber optic connections during installation and maintenance. It is used in telecommunications, network construction and testing, as well as in industrial automation, where high measurement accuracy is required. The mode-transparent property makes it particularly flexible for various application scenarios.

Compatibility and accessories refers to use with devices supporting FC and LC connectors. The cable is designed for use with standard measuring instruments that support these connector types.

Operational advantages include high reproducibility of measurement values, universal usability regardless of mode type, and easy handling. The mode-transparent design reduces the need for multiple reference cables for different systems. Use as a standard reference increases the reliability of measurement results and supports compliance with quality standards in fiber optic technology.
