Networking Cable ROLINE 21.15.3340 0.15m Cat6a U/FTP Blue

The ROLINE 21.15.3340 0.15m Cat6a U/FTP Blue is a short patch cable engineered for high-speed wired networking over short distances. Complying with Cat6a specification and using U/FTP shielding, the cable reduces crosstalk and external electromagnetic interference. It is terminated with RJ-45 connectors on both ends and comes in a compact 0.15 m length, suitable for tidy connections between closely located devices and for use in patch panels or switch ports where excess cable should be avoided.

Advantages

This Cat6a cable provides improved signal integrity compared with lower-category cables due to its U/FTP shielded construction, which combines an overall foil with individually shielded twisted pairs to limit alien crosstalk. The short 0.15 m length minimizes signal attenuation and clutter in rack or desktop environments. Fitted with standard RJ-45 plugs at both ends, the cable supports straightforward plug-and-play installation with common networking equipment. The blue jacket offers visual identification in multi-cable installations.

Suitable for

• Connecting devices in tight spaces where excess cable length is undesirable
• Patching between adjacent switch ports or wall outlets and network devices
• Use in server racks or network cabinets to maintain tidy cable management
• Short links requiring Cat6a performance and reduced interference

Key specifications

• Cable category: Cat6a
• Shielding: U/FTP (overall foil with individually shielded twisted pairs)
• Length: 0.15 m
• Connectors: RJ-45 to RJ-45
• Colour: Blue

How to use

Insert each RJ-45 connector into the corresponding Ethernet port of the devices to be connected, ensuring a secure click for reliable contact. Use the cable for short patching tasks such as linking neighboring switch ports, connecting a network device to a nearby wall outlet, or tidy internal connections within a rack. Avoid bending the cable sharply at the connector ends; maintain gentle bend radii to preserve shielding and pair integrity.

Usage recommendations

For best performance, route the cable away from sources of strong electromagnetic interference and avoid running it in parallel with power cables. Use the short 0.15 m length where minimal slack is required to reduce clutter; for longer runs, select an appropriate longer Cat6a cable. Inspect connectors before use and replace the cable if the jacket or plugs show visible damage.
