The patch cable from the brand Synergy 21, manufacturer's number S216012, is a data cable of category Cat6 with a bandwidth of 250 MHz, designed for use in modern network infrastructures. It features S-STP (S/FTP) shielding, where each pair of conductors is individually foil-shielded and additionally a total braid surrounds the entire cable. This shielding technology ensures high resistance to interference and minimizes electromagnetic influence, which is particularly advantageous in environments with high electromagnetic noise. The cable is halogen-free (LSZH), meaning that in the event of a fire, it produces lower toxicity and smoke emissions, making it suitable for safer applications in indoor spaces. The cable length is 0.5 meters, the color is grey, and the cable has a round cross-section with an outer diameter of 5.80 mm. The individual conductors have a gauge of AWG 27, ensuring sufficient conductivity for the intended applications. The connectors at both ends are RJ45 connectors with latch nose protection, enabling a secure and stable connection in the network. The connector type is described as long, indicating a standard configuration typically used in switches, routers, and other network devices.

Applications
This patch cable is designed for use in local area networks (LAN), particularly in environments where high data transfer rates and interference resistance are required. It is suitable for connecting end devices such as computers, printers, network switches, or routers to network outlet sockets or patch panels. The Cat6 category supports data rates up to 1 Gbit/s over the full cable length of 0.5 m, which is sufficient for typical use in offices, server rooms, or small networks. The halogen-free jacket (LSZH) also makes the cable suitable for use in enclosed spaces where fire safety requirements are increased.

Functions and Equipment in Detail
The S-STP (S/FTP) shielding provides a double layer of protection: each pair of conductors is individually foil-shielded to minimize crosstalk within the cable, and the entire cable is surrounded by a metallic braid that shields against external electromagnetic interference. This construction ensures high signal integrity and reduces sensitivity to interference. The RJ45 connectors with latch nose protection ensure a secure connection, protecting against accidental disconnection and enabling a stable mechanical connection in network devices. The grey-colored cable is typically intended for use in professional environments where uniform cable color coding in racks or patch panels is desired.

Technology Explained Simply
The designation S-STP (S/FTP) stands for “Screened Shielded Twisted Pair” or “Screened Foiled Twisted Pair”. This means that each pair of conductors is individually wrapped in a metallic foil (foil shielding), and additionally, the entire cable is surrounded by a metallic braid (screen). This double shielding ensures that the cable is protected against both external interference and internal crosstalk between conductor pairs. The Cat6 category guarantees a maximum bandwidth of 250 MHz, sufficient to transmit data rates up to 1 Gbit/s over the full cable length of 0.5 m. The halogen-free (LSZH) jacket reduces the formation of toxic gases and smoke in case of fire, increasing safety at the installation site. The AWG 27 conductor gauge is sufficient for cables of this length and category to ensure the required conductivity.

Compatibility and Accessories
The patch cable is compatible with all devices that support an RJ45 connection, such as switches, routers, network outlet sockets, PCs, printers, and other network end devices. It can be used in combination with other products from the brand Synergy 21, for example, with velcro cable ties (e.g. 25 m, 20 mm wide, black, item S215680) or flexible spiral organizers (9–65 mm, 10 m, black), to neatly route and secure cables in racks or patch panels. Also available are transparent cable ties in various lengths (e.g. 160 mm, 200 mm) to make cable structures more transparent. These accessory items support professional cabling and facilitate maintenance and identification of the cables.

Installation and Mounting
Installation is done by simply plugging the RJ45 connectors into the corresponding sockets of network devices or outlets. The connectors are equipped with latch nose protection, ensuring a secure connection. The cable length of 0.5 m is suitable for short connections within a rack or between adjacent devices. The round shape and outer diameter of 5.80 mm allow for easy routing, even in confined spaces. The halogen-free jacket requires no special precautions during installation, as it does not pose any particular chemical or toxicological risks.

Operational Advantages
The patch cable provides reliable and stable data transmission with high bandwidth and low susceptibility to interference. The double shielding (S-STP) ensures high signal quality, even in environments with electromagnetic interference sources. The halogen-free jacket (LSZH) increases safety during operation, especially in enclosed spaces. The grey-colored cable supports structured cabling, facilitating maintenance and identification of cables. The RJ45 connectors with latch nose protection ensure a secure and durable connection that remains stable even with frequent plugging and unplugging. The cable length of 0.5 m is ideal for short connections in server rooms, offices, or patch panels.

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