The patch cable from the brand Synergy 21, manufacturer's number S216061, is a data cable of category 6 (Cat6) with a length of 5 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, in which each pair of conductors is individually foil-shielded and additionally a braided overall shield surrounds the entire cable. This shielding system reduces electromagnetic interference and ensures stable transmission even in environmentally susceptible areas. The maximum bandwidth is 250 MHz, enabling use in modern networks with high requirements for speed and signal quality. The cable is fitted with RJ45 connectors at both ends, which are equipped with latch nose protection to prevent mechanical damage to the contacts. The cable colour is grey, making it well-integrated into standardised IT infrastructures. The jacket is made from halogen-free material (LSZH), which minimises the formation of toxic smoke gases in the event of a fire and increases safety.

Applications
This patch cable is suitable for use in local area networks (LAN), particularly in offices, server rooms, or for connecting network devices such as switches, routers, PCs, or network printers. The shielding makes it especially suitable for environments with high electromagnetic interference, for example, near machines, transformers, or other electrical equipment. Category 6 enables data rates up to 1 Gbit/s over the full cable length of 5 metres, and the 250 MHz bandwidth is also sufficient for future requirements such as PoE++.

Functions and Equipment in Detail
The connectors are long, ensuring better mechanical stability and a secure connection in sockets. The latch nose protection function protects the contacts from damage during insertion and removal. The cable itself has a round cross-section with an outer diameter of 5.80 mm and is made with AWG 27 (individual conductor gauge), providing sufficient conductivity with moderate flexibility. The use of LSZH material in the jacket meets requirements for safe and environmentally compatible material selection, especially in enclosed spaces such as server rooms or offices.

Technology Explained Simply
This double shielding minimises electromagnetic interference (EMI) and crosstalk between the conductors. Category 6 (Cat6) is a standard cable category for network cables designed for data rates up to 1 Gbit/s over 100 metres. At a cable length of 5 metres, the cable’s performance is fully utilised. The 250 MHz bandwidth enables use for PoE (Power over Ethernet), PoE+, and PoE++, allowing the cable to also supply power to network devices such as IP cameras, access points, or telephones.

Compatibility and Accessories
The patch cable is compatible with all devices that support RJ45 connectors, including switches, routers, PCs, printers, and other network end devices. It can be used in existing network infrastructures that use Cat6 or Cat5e cables. As accessories, various cable ties and cable organisers are available to ensure proper routing and securing of cables in racks or enclosures. These include, for example, cable ties in various lengths and materials, as well as flexible spiral organisers that enable structured cable routing.

Installation and Mounting
Installation is carried out by simply inserting the RJ45 connectors into the corresponding sockets of the network devices. The long connectors with latch nose protection ensure a secure and stable connection. The cable is flexible enough to be routed in standard 48,3 cm ( 19 inch ) racks or enclosures without causing mechanical stress. The halogen-free jacket coating requires no special precautions during installation, as no harmful fumes are released.

Advantages in Operation
The cable provides reliable and stable data transmission with high bandwidth. The double shielding ensures low interference, which is particularly beneficial in critical applications. The use of LSZH material increases safety in the event of fire. Compatibility with PoE technologies expands the range of applications, as the cable simultaneously transmits data and power. The grey colour supports structured and clear cable routing in professional IT environments.
