Networking cable EFB Elektronik K5516.0,25 Cat6 S/FTP (S-STP) RJ-45–RJ-45 0.25 m Orange

EFB Elektronik K5516.0,25 is a short Cat6 S/FTP (S‑STP) patch cable with RJ‑45 connectors on both ends. With a 0.25 m length and bright orange jacket, the cable is designed for short patch connections in racks, switches, patch panels and desktop devices where clear visual identification and minimal signal interference are required. It supports up to 5000 Mbit/s and operation to 250 MHz, meeting Cat6 performance for high-speed local networks.

Advantages

The cable features S/FTP shielding (overall braid plus individually shielded pairs) to reduce crosstalk and protect against external electromagnetic interference. Two shielded RJ‑45 plugs conform to IEC 60603‑7‑5, while a moulded strain relief with latch protection improves connector durability and reduces stress at the termination. The orange LSZH jacket is halogen-free, flame-retardant and low-smoke, helping safety and identification in installations.

Suitable for

• Short patch connections between network equipment in racks and cabinets
• Linking switches, patch panels and servers in data closets
• Desktop connections for VoIP phones, PCs and networked peripherals
• Environments requiring reduced electromagnetic interference due to S/FTP shielding

Key specifications

• Cable category: Cat6, supports up to 250 MHz
• Data rate: up to 5000 Mbit/s (5 Gbit/s)
• Length: 0.25 m
• Conductor: 4 pairs, AWG27/7, PiMF (pairs in metal foil)
• Shielding: S/FTP — overall braid plus individually shielded pairs
• Connectors: RJ‑45 to RJ‑45, shielded plugs
• Wiring standard: TIA/EIA 568B
• Outer diameter: approximately 6.2 mm
• Jacket: LSZH (low smoke zero halogen), flame retardant
• Mechanical: moulded strain relief with latch protection

How to use

Insert each RJ‑45 plug into the corresponding network port on your switch, patch panel, router or device until the latch clicks. Use the cable for short jumper connections inside racks or to link equipment on a desktop. Ensure connectors are fully seated and avoid excessive bending or tension at the moulded strain relief to maintain performance. Follow standard TIA/EIA cabling practices when routing and dressing the cable in patch panels or cable management systems.

Usage recommendations

For best performance, keep the cable length appropriate for patch use (0.25 m) and avoid sharp bends or kinks. Use the orange colour for quick identification of Cat6 S/FTP lines in patch fields, and segregate high-power or noisy electrical runs to minimize interference despite the cable’s shielding.
