bkl electronic RJ45 Patch Cable CAT8.1 U/FTP 0.25 m Black (Model 144009)

bkl electronic RJ45 Patch Cable CAT8.1 U/FTP 0.25 m Black is a short, shielded Ethernet patch cable designed for high-frequency, short-distance network connections. With CAT8.1 U/FTP construction, this cable provides improved protection against electromagnetic interference and supports high data rates suitable for structured cabling in environments that require shielded connections between devices such as switches, patch panels and network ports.

Advantages

The shielded U/FTP design reduces crosstalk and external interference by wrapping each twisted pair in foil and adding an overall shield, which helps maintain signal integrity at higher frequencies. The very short 0.25 m length minimizes latency and cable clutter in dense rack or patch-panel installations. The cable’s robust RJ45 terminations and compact form factor simplify connections in tight spaces while preserving performance required for modern data-center and laboratory setups.

Suitable for

• Interconnecting switches and patch panels in server racks and data centers
• Short links between network devices in home labs or test benches
• Shielded connections where electromagnetic interference is a concern
• High-speed Ethernet links requiring CAT8.1 performance over short distances

When it may not be suitable

This 0.25 m patch cable is intended for very short point-to-point connections; it is not suitable when longer cable runs are required to reach distant equipment. Its shielded construction requires compatible shielded ports and proper grounding to realize the shielding benefits; in unshielded installations the advantage of U/FTP will be limited.

Key specifications

• Category: CAT8.1
• Shielding: U/FTP (overall and foil-shielded twisted pairs)
• Connector type: RJ45
• Length: 0.25 m
• Color: Black

How to use

Connect one RJ45 end to the source device (for example, a switch or patch panel) and the other end to the target device or port. Ensure both connected devices have shielded RJ45 ports and that the system grounding is properly implemented to take full advantage of the U/FTP shielding. Route the cable so it experiences minimal bending and avoids tight kinks; the short length is suitable for tidy patching within racks and cabinets.

What to consider before purchase

• Required cable length — verify that 0.25 m covers the distance between ports
• Port compatibility — confirm devices support shielded RJ45 connections and grounding
• Application environment — ensure short, high-frequency links are the intended use

Usage recommendations

Use this cable for direct, short interconnections inside racks or between adjacent devices. Pair with shielded patch panels and properly grounded infrastructure to preserve signal integrity and the shielding benefit.
