The patch cable from the brand Synergy 21, manufacturer's number S216008, is a Cat6 data cable with a length of 0.5 metres, designed for use in network infrastructures. It features S-STP (S/FTP) shielding, where each pair of conductors is protected by a foil shield and additionally by an overall metal braid shield. This shielding reduces electromagnetic interference and ensures stable data transmission. The cable is equipped with RJ45 connectors at both ends, featuring strain relief protection to prevent mechanical damage. The cable colour is black, and the jacket is made of halogen-free material (LSZH), which does not release toxic gases in case of fire, making it suitable for use in enclosed spaces.

Applications
This patch cable is designed for use in structured cabling systems, particularly in offices, server rooms, or for connecting network devices such as switches, routers, or computers. Category 6 enables data transmission rates up to 1 Gbit/s over the full cable length of 0.5 m. The frequency bandwidth of 250 MHz also supports future requirements for bandwidth and signal quality. Due to its shielding and halogen-free jacket, it is also suitable for critical applications in data centres or environments with high safety requirements.

Functions and Equipment in Detail
The cable is round and has an outer diameter of 5.8 mm. The individual conductors have a gauge of 27 AWG, providing sufficient conductivity while ensuring good flexibility. The connectors are coated with 80A PVC, ensuring mechanical stability and a secure fit in the network socket. The contact pins are gold-plated (3 µm), ensuring high corrosion resistance and reliable electrical contact. The shielding consists of an aluminium-polyester foil per conductor pair, as well as an additional aluminium metal braid around the entire cable, providing effective protection against electromagnetic interference (EMI).

Technology Explained Simply
The designation S-STP (also known as S/FTP) means that each conductor pair is individually shielded with foil, and additionally the entire cable is shielded with a metal braid. This double shielding ensures that external interference (e.g. from motors, lights, or other electrical devices) does not affect data transmission. The frequency of 250 MHz enables high data rates and is compatible with standards ISO/IEC 11801, EN50173-1, and ANSI/TIA-568-C.2. The use of LSZH material ensures that no toxic gases are released in case of fire, increasing safety at the installation site.

Compatibility and Accessories
The patch cable is designed for use with network devices that support RJ45 connectors. It is compatible with PoE (Power over Ethernet), PoE+, and PoE++, meaning it can also be used to power devices such as IP cameras, access points, or telephones via the network cable. Compatible accessories are available, including cable ties in various lengths and materials (e.g. transparent cable ties L160 mm, Velcro tape 25 m, B 20 mm) as well as flexible cable organizers to support orderly cabling.

Installation and Mounting
Installation is carried out by simply plugging the RJ45 connectors into the corresponding sockets of the network devices. The connectors feature strain relief protection, ensuring mechanical stability and preventing the cable from being pulled out. The minimum bending radius is 60 mm, allowing flexible installation even in confined spaces. The cable is designed for an operating temperature range of -20 °C to +75 °C, enabling use in various environments.

Operational Advantages
The combination of S-STP shielding, halogen-free jacket, and gold-plated contacts ensures high reliability and longevity. Support for PoE technologies expands the range of applications, as power and data are transmitted over a single cable. The cable is packaged in a blister pack from the brand Synergy 21, which protects the cable from damage and allows for clean presentation. Compliance with ROHS 3.0 and REACH demonstrates the environmental compatibility of the product.
