The Goobay CAT-6 modular coupling (manufacturer's part number 93963) is a network connector for joining and extending two network cables with RJ45 connectors. The device features two RJ45 female connectors (8P8C) and serves as a passive connection point in a local network, enabling cable connections without requiring an active switch or router. The robust zinc die-cast enclosure ensures mechanical stability and protects internal contacts from external influences. The coupling is equipped with a genuine metal shielding, providing effective protection against electromagnetic interference and enhancing network signal quality.

Applications
This modular coupling is suitable for use in various environments, including laboratories, workshops, home networks, and professional network installations. It is commonly used to extend network cables in rooms where a direct connection to a wall socket is not possible, or to create temporary connections. It can also be used in the home entertainment sector, for example, to connect streaming boxes, gaming consoles, or smart TVs via Ethernet.

Functions and Features in Detail
The coupling features a 1:1 pinout, meaning each contact on one side is directly connected to the corresponding contact on the other side. This ensures accurate and undistorted signal transmission without rerouting or conversion. The contacts are made with gold-plated contacts, ensuring a reliable and long-lasting electrical connection. The female connectors are designed for data and power transmission over the network cable.

Technology Explained Simply
The maximum bandwidth is 250 MHz, making the coupling suitable for use with CAT-6 network cables. This bandwidth supports data transfer rates up to 1 Gbit/s, which is sufficient for most modern network applications. PoE+ support according to IEEE 802.3at allows power delivery over the network cable, enabling devices such as IP cameras, access points, or telephone systems to be powered directly through the coupling without requiring a separate power source. The metal shielding protects signals from interference caused by other electrical devices or environmental conditions.

Compatibility and Accessories
The coupling is compatible with CAT-6 network cables and can be connected to any RJ45 connector. It is not designed for optical signals, but for electrical data transmission. There are no specific accessories mentioned in relation to this product; the coupling is used as a standalone component.

Installation and Mounting
Installation is done by simply inserting the RJ45 connectors of the two cables to be connected into the coupling's female connectors. No tools or additional mounting work is required. The coupling can be used at any point in the network as long as mechanical stability is ensured. It can be used in enclosed spaces or near electrical devices, as the shielding minimizes interference.

Operational Advantages
The coupling provides a reliable, stable, and durable connection between two network cables. The metal shielding and robust construction ensure a long service life and low failure rate. PoE+ support expands its applications by enabling power delivery to network devices over the cable. Its simple handling and direct use without additional configuration make the coupling a practical component in network installations.
