The patch cable from Synergy 21, manufacturer's number S216405, is a Cat6A data cable with a length of 3 metres, designed for use in networks with high requirements for bandwidth and signal integrity. The cable features S-STP (S/FTP) shielding, where each pair of conductors is individually shielded with foil and additionally an outer braid surrounds the entire cable. This construction ensures a high level of protection against electromagnetic interference and crosstalk, which is particularly advantageous in dense network environments. The jacket is made of LSZH material (halogen-free), meaning that in case of fire, it produces minimal smoke and does not release toxic gases – an important property for use in enclosed spaces such as server rooms or offices. The cable colour is grey, providing a neutral appearance and integrating well into standardised cable installations.

Applications

The cable is designed for use in modern Ethernet networks that support bandwidths up to 10 Gbit/s over short distances. It complies with the standards ISO/IEC 11801 Class Ea Channel, as well as EN 50173-1 and ANSI/TIA-568-C.2, confirming adherence to international standards for structured cabling. The frequency bandwidth of 500 MHz enables stable data transmission even under high loads. Due to its shielding and material quality, it is suitable for use in environments with high electromagnetic interference, such as near servers, enclosures or industrial equipment.

Functions and Equipment in Detail

At both ends, the cable is fitted with RJ45 connectors equipped with a latching nose protection. This design protects the contact tongues from damage during insertion and ensures a secure connection. The connectors are long (3U format), providing better stability in network devices or switches. The individual conductors have a gauge of 26 AWG, offering sufficient conductivity for the transmitted data volume. The cable connection is ensured through a 100% electrical test (Open/Short/Miss Wire) and an insulation resistance test (DC 300V, min. 10 MΩ) to guarantee reliable performance.

Technology Explained Simply

The S-STP (S/FTP) shielding combines the benefits of pair foil shielding and overall braid shielding. Each of the four conductor pairs is individually shielded with a metallic foil, minimising interference within the cable. The outer braid protects the entire cable from external electromagnetic influences. This double shielding is particularly important to maintain signal quality at high frequencies. The LSZH material is flame-retardant and produces only minimal smoke when heated, increasing safety at the installation site. The PoE support (PoE/PoE+/PoE++) allows power delivery over the network cable, which is relevant for IP cameras, access points or telephone systems. The maximum operating temperature is +75 °C, and the minimum temperature is -20 °C, allowing use in a wide range of environments.

Compatibility and Accessories

The cable is compatible with all devices supporting Cat6A and RJ45 standards. It can be used in networks with PoE technology, where power is supplied via the cable. As accessories, various cable ties and organisers are available, including Velcro tape, flexible spiral organisers, and cable ties in different lengths, which assist in proper cable routing and bundling. These products are also from Synergy 21 and match the patch cable in design and quality.

Installation and Mounting

Installation is carried out by simply inserting the RJ45 connectors into the corresponding sockets of switches, routers, PCs or other network devices. The long connectors ensure a secure connection, and the latching nose protection prevents accidental disconnection. The minimum bending radius is 60 mm, which should be considered during installation to avoid damaging the cable. Packaging is done in a blister pack from Synergy 21, which protects the cable from mechanical damage.

Operational Advantages

Thanks to the high shielding and use of high-quality materials, the cable provides stable and reliable data transmission. PoE support enables simplified installation, as no additional power supplies are required. The halogen-free construction increases safety during operation, especially in enclosed spaces. The 100% electrical testing ensures that each cable is checked for functionality before delivery, increasing reliability in operation.
