The patch cable from the brand Synergy 21, manufacturer's number S216051, is a data cable of category Cat6 with a bandwidth of 250 MHz, designed for use in network infrastructures. It features S-STP (S/FTP) shielding, where each pair of conductors is individually foil-shielded and the entire cable is additionally wrapped in a braid. This shielding construction ensures high resistance to interference and minimizes electromagnetic influence, which is particularly advantageous in environments with high electromagnetic noise or in critical network applications. The cable is halogen-free (LSZH), meaning that no toxic or corrosive gases are released in case of fire, making it suitable for use in enclosed spaces and in IT infrastructure. The cable colour is grey, and the length is 3 metres. The connectors at both ends are RJ45 connectors with latch nose protection, ensuring a secure and stable connection and protecting the cable from mechanical damage. The connectors are long, allowing for better fit in standard RJ45 sockets. The cable has a round cross-section with an outer diameter of 5.80 mm and a single conductor thickness of AWG 27, providing sufficient conductivity for the intended applications. Power over Ethernet (PoE) is supported, with the cable suitable for PoE, PoE+ and PoE++, enabling use with IP cameras, access points, or other PoE-enabled devices.

Applications
This patch cable is designed for use in local area networks (LAN), particularly in environments where high data integrity and interference resistance are required. It is suitable for connecting network devices such as switches, routers, PCs, laptops, IP phones, and other PoE-enabled end devices. Due to the S-STP shielding, it is especially suitable for areas with high electromagnetic interference, such as server rooms, data centres, or industrial environments. The halogen-free jacket also makes it suitable for use in enclosed spaces and public infrastructure where fire safety requirements apply.

Functions and Equipment in Detail
The S-STP shielding (also known as S/FTP) provides a double layer of protection: each of the four conductor pairs is individually shielded with a metallic foil, and the entire cable is additionally surrounded by a metallic braid. This construction reduces electromagnetic interference (EMI) and crosstalk between conductor pairs, resulting in stable and reliable data transmission. The RJ45 connectors with latch nose protection ensure a mechanically robust connection and prevent accidental disconnection from the socket. The grey coloured jacket allows for easy visual identification in cable management, especially in racks or server rooms. The length of 3 metres is a standard length for patch cables, sufficient for most applications in IT infrastructure without leaving excessive cable residue.

Technology Explained Simply
The designation Cat6 refers to Category 6, which supports a maximum bandwidth of 250 MHz and is suitable for data transmission rates up to 10 Gbit/s over short distances. The S-STP shielding (S/FTP) is a high-quality shielding technology that protects both individual conductor pairs and the entire cable. This is particularly important when the cable is routed near electrical devices, motors, or other sources of interference. The halogen-free (LSZH) jacket is a safety feature that does not release toxic gases in case of fire, increasing safety in enclosed spaces. The PoE support (PoE, PoE+, PoE++) allows power supply to end devices via the network cable, eliminating the need for separate power sources. The AWG 27 conductor thickness is sufficient for the intended applications, as it provides adequate conductivity without being unnecessarily thick.

Compatibility and Accessories
The patch cable is compatible with all devices that support RJ45 connectors and Cat6 or higher-rated network cables. It can be used in combination with other products from the Synergy 21 range, such as cable ties, Velcro straps, or cable organizers, to ensure proper cabling and structured cable management. Suitable accessories include, for example, cable ties in various lengths and types, Velcro straps, and flexible cable organizers, which help guide and organize cables in racks or server rooms. These products support professional installation and maintenance of network infrastructure.

Installation and Mounting
The installation of the patch cable involves simply inserting the RJ45 connectors into the corresponding sockets of the network devices. The connectors are equipped with latch nose protection, ensuring a secure connection. During installation, care should be taken to avoid excessive bending, kinking, or pressure on the cable to maintain the integrity of the shielding and conductors. The use of cable ties or organizers can help route the cable properly and ensure neat cabling.

Operational Advantages
The patch cable provides reliable and stable data transmission thanks to the S-STP shielding and Cat6 standard. The halogen-free jacket increases safety in case of fire. PoE support enables simplified installation of end devices, as no additional power supplies are required. The robust construction with latch nose protection ensures long service life and a secure connection. The grey colour facilitates visual identification in cable management, simplifying maintenance and fault diagnosis.
