Networking Cable ROLINE 21.15.2640 Blue 0.5m Cat6 S/FTP

The ROLINE 21.15.2640 Blue 0.5m Cat6 S/FTP networking cable is a short patch cable designed for reliable Ethernet connections in compact setups. It complies with Cat6 performance parameters and uses S/FTP shielding (overall braid plus individually foil screened pairs) to minimise crosstalk and external electromagnetic interference. Both ends are fitted with standard RJ-45 connectors and the cable is finished in blue PVC jacketing, suitable for visible patching in home or office network installations.

Advantages

The S/FTP construction provides improved protection against near-end crosstalk and external noise compared with unshielded cables, supporting stable high-speed data transmission. Its Cat6 specification ensures performance up to the standard limits for Gigabit Ethernet and suitable headroom for some 10 Gigabit applications over short distances. The 0.5 m length keeps patching tidy by reducing slack, while the RJ-45 connectors deliver universal compatibility with network ports and patch panels. The blue jacket aids visual identification in structured cabling environments.

Suitable for

• Short patch connections between network devices in racks or wall outlets
• Connecting switches to patch panels or directly to servers and workstations
• Desktop networking where minimal cable length improves organization
• Installations requiring reduced electromagnetic interference and improved signal integrity

Key specifications

• Cable category: Cat6
• Shielding: S/FTP (overall braid + individually foil screened pairs)
• Connector type: RJ-45 to RJ-45
• Length: 0.5 m
• Colour: Blue

How to use

Connect one RJ-45 connector to the network port of your device and the other to the corresponding port on a switch, router, patch panel or wall socket. Ensure connectors are fully inserted until the latch clicks to secure the connection. For best performance maintain gentle bends and avoid sharp kinks; keep the cable away from strong sources of electromagnetic interference when routing. The short 0.5 m length is intended for tidy, close-proximity connections rather than long runs.

Usage recommendations

Use this cable for local patching inside cabinets, between adjacent devices or on desktops where a short, shielded Cat6 link is required. Avoid stretching beyond the specified length and do not remove the connector boots; if used in an environment with significant electrical noise, ensure proper grounding of connected equipment to benefit from the cable's shielding.
