Networking cable EFB Elektronik K8449.20 — Cat5e F/UTP (FTP), RJ‑45 to RJ‑45, 20 m, grey

EFB Elektronik K8449.20 is a 20 m Cat5e networking cable designed for wired Ethernet connections. The cable uses F/UTP (FTP) construction with an overall foil shield and unshielded twisted pairs, terminated with RJ‑45 plugs on both ends. It provides reliable data transmission at Cat5e performance levels and reduced susceptibility to electromagnetic interference thanks to the foil shielding. The grey jacket makes it suitable for visible installations in home and office environments.

Advantages

The F/UTP (FTP) design offers additional protection against external electromagnetic interference while keeping pair conductors unshielded for flexible handling. With 20 m length and standard RJ‑45 terminations, the cable connects switches, routers, patch panels and network devices without adapters. The Cat5e specification ensures support for typical Ethernet speeds used in residential and small-business networks. The grey outer sheath is durable and easy to route along walls, under desks or through cable conduits.

Suitable for

• Connecting desktop computers, printers and networked peripherals to a router or switch
• Patch panel to switch connections in home or small office installations
• Wiring for IP cameras and VoIP phones where Cat5e performance is sufficient
• Temporary or permanent runs up to 20 m in length within buildings

Key specifications

• Cable category: Cat5e
• Shielding: F/UTP (overall foil shield, unshielded twisted pairs)
• Connectors: RJ‑45 to RJ‑45, 8P8C
• Length: 20 m
• Outer jacket color: grey
• Usage environment: indoor horizontal cabling, patching

How to use

Plug each RJ‑45 connector into the corresponding network port on devices such as routers, switches, patch panels or computers. Ensure connectors are fully seated until the locking tab engages. For best performance, avoid tightly coiling the cable or sharply bending it near the connector; maintain the natural bend radius. Route the cable away from high‑power electrical lines or fluorescent lighting to minimize potential interference, even though the foil shielding reduces susceptibility.

Recommendations

Use this Cat5e F/UTP cable for standard Ethernet links up to 20 m where Cat5e bandwidth is adequate. For installations requiring higher bandwidth or additional pair-level shielding, consider Cat6 or shielded pair (STP) alternatives. Avoid running the cable in direct contact with high-voltage wiring and secure it with cable clips or Velcro ties to prevent strain on the RJ‑45 connectors.
