Zubehör ST/PC-ST/PC Referenz-Kupplung content_copy

The ST/PC-ST/PC reference coupling from Softing IT Networks is a specific accessory for connecting and testing fiber optic cables in the field of data communication. It serves as a reference component in optical networking technology, particularly for calibrating and validating measuring instruments as well as for checking the performance of fiber optic connections. The coupling is designed for use in professional environments where high accuracy and reproducibility of measurement results are required.

Reference Coupling
The designation ST/PC-ST/PC describes the two connected connector types: ST (Straight Tip) with PC (Physical Contact) polishing on both ends. This coupling enables the connection of two ST/PC connectors, where the PC polishing ensures optimal light transmission by minimizing reflections. As a reference coupling, it is used in practice for calibrating OTDRs (Optical Time Domain Reflectometers) or other optical measuring instruments to check and calibrate measurement accuracy.

Applications
The coupling is used in the installation, maintenance, and diagnosis of fiber optic networks, particularly in telecommunications, industrial environments, and data centers. It is frequently employed in laboratory environments or during the commissioning of network infrastructures, where a reproducible and known optical performance of the connection is required. The use as a reference component enables the detection of measurement deviations and ensures the quality of optical connections.

Functions and Equipment in Detail
The ST/PC-ST/PC reference coupling is specifically designed for use with fiber optic cables. The connection is made via two ST/PC connectors, ensuring a secure and mechanically stable connection. The PC polishing ensures low backscattering, which is crucial for precise optical measurements. The coupling is not intended as a permanent connection in the network, but serves as a calibration unit for measuring instruments.

Technology Explained Simply
The coupling consists of a housing in which two ST/PC connectors are connected. The optical performance of the coupling is defined and known, so it serves as a reference point for measurements. The use of ST connectors, which feature a metal cylinder with a centered fiber core, enables precise alignment of the fibers. The PC polishing minimizes reflections at the fiber core surface, improving signal quality and increasing measurement accuracy.

Compatibility and Accessories
The coupling is compatible with all devices that support ST/PC connectors. It can be used in combination with OTDRs, optical power meters, or other optical testing equipment to verify the accuracy of measurement results. The use as a reference component requires no additional adapters or converters, as the connectors are standardized.

Mounting and Installation
Mounting is done by simply inserting the two ST/PC connectors into the coupling. No special tools or additional mounting components are required. The coupling is directly integrated into the measurement chain to validate optical performance. The connection is mechanically stable and can be held without additional fastening.

Advantages in Operation
The use of the ST/PC-ST/PC reference coupling enables reproducible and precise measurement of optical parameters. The known optical performance of the coupling serves as a reference to detect measurement deviations and ensure the quality of optical connections. The coupling is robust and designed for professional use, ensuring reliable performance even with frequent use. The standardization of the connectors ensures universal compatibility with common measuring instruments.
