The patch cable from the brand Synergy 21, manufacturer number S216041, is a data cable of category 6 (Cat6) with a length of 2 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 quality, especially in environments with high electromagnetic noise. The cable jacket is made of halogen-free material (LSZH), which minimizes the formation of toxic smoke gases in case of fire and increases safety. The cable colour is grey, making it discreetly integrable in typical IT and network infrastructures.

Applications
This patch cable is suitable for use in local area networks (LAN), particularly in offices, server rooms, and data centres. It supports data transmission up to a frequency of 250 MHz, meeting the requirements of modern networks such as Gigabit-Ethernet and also PoE applications. The cable construction with S-STP shielding makes it especially suitable for environments where high resistance to interference is required, for example near electrical devices, motors, or other sources of electromagnetic interference.

Functions and Equipment in Detail
At both ends of the cable, RJ45 connectors with latch nose protection are mounted. The latch nose protection protects the connector contacts from damage during insertion and removal and ensures a secure connection. The connectors are long, enabling better fit into standard RJ45 sockets and stabilizing the connection. The conductor gauge is 27 AWG, ensuring sufficient conductivity for the intended applications. The cable is round and has an outer diameter of 5.80 mm, allowing for flexible handling and installation.

Technology Explained Simply
The designation S-STP (also referred to as S/FTP) stands for Screened Shielded Twisted Pair and means that each pair of conductors is individually foil-shielded and the entire cable is additionally enclosed in a metallic braid. This double shielding ensures high immunity against electromagnetic interference (EMI) and prevents crosstalk between the conductors. The frequency bandwidth of 250 MHz enables data transmission at high speeds, as required for Gigabit-Ethernet (1000 Mbit/s).

Compatibility and Accessories
The patch cable is compatible with all devices that use RJ45 connectors, such as switches, routers, network adapters, PCs, and servers. It can be used in combination with accessories such as cable ties, Velcro straps, or spiral organizers to keep cable routing neat and structured. Suitable accessories include, for example, cable ties in various lengths and colours, Velcro straps, and flexible spiral organizers for better cable guidance and bundling in rack systems or at workstations.

Installation and Mounting
Installation is carried out by simply inserting the RJ45 connectors into the corresponding sockets of the network devices. The connectors are equipped with latch nose protection, ensuring a secure and long-lasting connection. The cable is flexible and can be easily routed in racks, enclosures, or at workstations. The halogen-free cable jacket meets fire safety requirements in enclosed spaces.

Advantages in Operation
The patch cable provides reliable and stable data transmission with high bandwidth. The double shielding ensures a low error rate and minimizes interference. Support for PoE technologies enables simplified installation of network devices, as no additional power supplies are required. The halogen-free material selection increases safety in case of fire. The cable is delivered in a blister pack from Synergy 21, enabling clean and damage-free storage and installation.
