The patch cable from the brand Synergy 21, manufacturer's number S216022, is a data cable of category 6 (Cat6) with a length of 1.0 metres. It is designed for use in network infrastructures where high data transfer rates and reliable signal transmission are required. The cable features S-STP (S/FTP) shielding, meaning that each individual wire pair is shielded with a foil covering, and additionally, the entire cable is surrounded by a braid. This shielding protects data transmission from electromagnetic interference and ensures stable performance at high frequencies up to 250 MHz. The cable jacket is made of halogen-free material (LSZH), which minimizes the formation of toxic smoke gases in case of fire, thus providing higher safety.

Applications
This patch cable is suitable for use in structured cabling systems, particularly in offices, server rooms, or for connecting network devices such as switches, routers, PCs, or network printers. The cable type is round and has an outer diameter of 5.80 mm, enabling flexible handling and easy installation. The grey colour supports clear cable structuring in complex networks, as colour coding improves visibility and organization.

Functions and Equipment in Detail
At both ends of the cable, RJ45 connectors with latch nose protection are mounted. The latch nose protection prevents accidental disconnection of the connector from the network port and enhances the mechanical stability of the connection. The connectors are long, which allows for better fit in certain device ports. The individual conductors have a gauge of 27 AWG, ensuring sufficient conductivity while maintaining flexibility. The S-STP (S/FTP) shielding provides high immunity against electromagnetic interference (EMI) and crosstalk, which is especially important in environments with high electromagnetic noise levels.

Technology Explained Simply
The designation S-STP (also referred to as S/FTP) stands for Shielded Twisted Pair with additional shielding of individual wire pairs. This construction reduces interference between wires (crosstalk) and protects the entire cable from external electromagnetic influences. The frequency bandwidth of 250 MHz enables high-speed data transmission, which is required for modern networks. The use of halogen-free jacket material (LSZH) is particularly advantageous in enclosed spaces such as server rooms or offices, as it does not release toxic gases when heated or in case of fire.

Compatibility and Accessories
The patch cable is compatible with all devices that support an RJ45 port, including network switches, routers, PCs, laptops, and network printers. It is suitable for use with PoE (Power over Ethernet), PoE+, and PoE++, meaning it can also be used to power end devices such as IP cameras or access points via the network cable. As accessories, various cable ties and organizers are available to support proper cable routing and bundling in 48,3 cm ( 19 inch ) racks or other installations. These include, for example, cable ties in different lengths and colours, as well as flexible spiral organizers that enable structured cable management.

Installation and Mounting
Installation is carried out by simply plugging the RJ45 connectors into the corresponding ports of the network devices. The long connectors with latch nose protection ensure a secure connection. The flexible cable construction facilitates routing, especially in confined spaces or when cabling in 48,3 cm ( 19 inch ) racks. The use of cable ties or organizers from the accessory range supports a neat and organized installation.

Operational Advantages
The patch cable provides reliable and stable data transmission with high bandwidth. The S-STP shielding ensures low interference, which is particularly beneficial in environments with many electrical devices or near high-frequency installations. The use of halogen-free material increases safety during operation. PoE compatibility expands application possibilities, as power and data can be transmitted over a single cable, simplifying installation and reducing the number of cables. The grey colour supports clear structuring in complex networks.

The cable is delivered in a blister pack from Synergy 21, enabling clean and damage-free storage and presentation. The packaging protects the cable from mechanical damage and contamination until installation.
