## Long description

The ROLINE 21.15.3940 Blue 0.15m Cat6a U/UTP networking cable is a short patch cable engineered for reliable high-speed data connections. Compliant with Cat6a performance, the cable supports elevated bandwidth and reduced crosstalk compared with lower-category cables. Both ends are fitted with standard RJ-45 connectors for plug-and-play compatibility with switches, routers, patch panels and networked devices. The compact 0.15 m length is intended for tidy connections where devices are close together, reducing cable clutter in racks, desks or equipment enclosures.
Advantages
The cable’s Cat6a construction provides improved signal integrity and headroom for 10 Gigabit Ethernet over short distances. U/UTP shielding reduces external electromagnetic interference without the complexity of individual pair shielding, offering a balance between performance and flexibility. The pre-terminated RJ-45 connectors ensure simple installation and immediate use, while the blue jacket makes cable routing and identification straightforward in multi-cable environments.
Suitable for
Short patch connections between network devices in racks, cabinets or on desks
Connecting switches to patch panels or adjacent servers
Temporary test setups and bench equipment connections
Environments where color-coded cabling improves organization
Key specifications
Cable category: Cat6a
Shielding type: U/UTP (overall shield absent; Unshielded Twisted Pair with overall unscreened jacket and pairing suitable for Cat6a performance)
Length: 0.15 m
Connectors: RJ-45 to RJ-45, pre-terminated
Color: Blue
How to use
Plug one RJ-45 connector into the network port of the first device and the other connector into the corresponding port of the second device. Ensure connectors are fully inserted and the latch clicks into place. Use the cable for short-distance patching inside racks, between adjacent devices or on desktops. Avoid sharp bends and kinks near the connector ends to maintain signal quality.
Usage recommendations
For best performance, keep the cable length appropriate to the connection distance and avoid running it alongside high-voltage power lines. If used in high-interference environments, consider shielded alternatives or additional routing separation. Inspect connectors periodically for dust or damage and replace the cable if the jacket or connectors show wear.
