Synergy 21 S216400 Patch cable RJ45, CAT6A 500Mhz, 0.25m, gray, S-STP (S / FTP), Sy content_copy

The patch cable from Synergy 21, manufacturer's number S216400, is a data cable of category Cat6A with a bandwidth of 500 MHz. It is used to connect network devices such as switches, routers, PCs, or network printers over short distances in a local area network (LAN). The cable is available in a length of 0.25 m and features a grey, round cable construction with an outer diameter of 6.20 mm. Shielding is performed using the S-STP (S/FTP) method, where each pair of conductors is shielded with foil and additionally protected by an overall shield made of aluminium-brass braid. This ensures high immunity against electromagnetic interference and minimizes crosstalk, which is particularly important in environments with high electromagnetic noise. The jacket is made of LSZH material (halogen-free), which produces minimal smoke and does not release toxic halogens in case of fire – an important property for use in enclosed spaces and server rooms.

Applications

The cable is designed for use in professional network infrastructures, particularly in server rooms, data centres, office buildings, and for cabling network devices in IT infrastructure. Category 6A enables data transfer rates up to 10 Gbit/s over short distances, making it suitable for modern network applications. Support for PoE (Power over Ethernet), including PoE+, PoE++ (IEEE 802.3at/af/bt), allows power supply to end devices such as IP cameras, access points, or VoIP phones via the same cable, thereby reducing the number of required power cables.

Functions and Equipment in Detail

At both ends of the cable, RJ45 connectors with strain relief protection are installed, ensuring a secure and stable connection. The connectors feature a 3U long-body design, providing better mechanical stability and easier handling when connecting into tight sockets. The individual conductors have a gauge of 26 AWG, offering sufficient conductivity while maintaining good flexibility. The cables are 100 % electrically tested, including open/short tests, insulation resistance (DC 300 V, minimum 10 MΩ), and contact resistance (maximum 1 Ω per meter). Compliance with the standards ISO/IEC 11801 Class Ea Channel Link, EN 50173-1, and ANSI/TIA-568-C.2 is confirmed by certification. The operating temperature range is between -20 °C and +75 °C, enabling use in a wide variety of environments.

Technology Explained Simply

The S-STP (S/FTP) shielding technology means that each of the four conductor pairs is individually shielded with a metallic foil, and additionally, the entire cable is surrounded by a metallic braid. This double shielding reduces electromagnetic interference (EMI) and crosstalk between conductor pairs, which is especially important at high data rates. The LSZH material of the jacket is flame-retardant and meets the requirements of standards IEC 60332-1-2 (flame retardancy), IEC 61034 (low smoke density), and IEC 60754-2 (halogen-free). The minimum bending radius is 60 mm, allowing safe bending without mechanical damage to the cable.

Compatibility and Accessories

The cable is compatible with all devices that support RJ45 connectors and Cat6A standards. It can be combined with other products from the Synergy 21 range, such as cable organizers, spiral or Velcro cable ties, which assist in proper routing and securing cables in rack systems or server rooms. These accessories are also available in the product range and support structured cabling.

Installation and Mounting

Installation is performed by simply inserting the RJ45 connectors into the corresponding sockets of the network devices. The connectors are equipped with strain relief protection, preventing accidental disconnection. The cables are delivered in blister packaging, which protects against mechanical damage and contamination during transport and storage. The packaging also includes a test report per cable, confirming the electrical properties.

Operational Advantages

The cable provides reliable, high-speed data transmission with high resistance to interference. PoE support enables simplified installation of network devices, as no additional power supplies are required. The halogen-free and flame-retardant jacket material increases safety in enclosed spaces. Certification according to international standards ensures compatibility and quality in professional networks.
