Networking cable No name Synergy 21 S215111 — Cat5e SF/UTP (S-FTP), RJ-45 to RJ-45, 1 m, Blue

No name Synergy 21 S215111 is a 1 m Ethernet patch cable compliant with the Cat5e standard. It uses SF/UTP (S-FTP) hybrid shielding to reduce electromagnetic interference and connects via RJ-45 plugs on both ends. The cable supports typical copper LAN speeds up to 100 Mbps or 1 Gbps depending on the connected equipment and network configuration. Its compact length and flexible sheath make it suitable for short links between switches, patch panels and wall outlets in home and office network environments.

Advantages

The SF/UTP (S-FTP) construction provides overall foil shielding plus individual pair screening, improving immunity to external EMI compared with unshielded cable. RJ-45 connectors on both ends ensure compatibility with standard network ports and quick plug-and-play installation. A 1 m length minimizes excess cable clutter in rack or desktop setups while preserving signal integrity for short-distance connections. The blue outer jacket makes the cable easy to identify in mixed-cable installations.

Suitable for

• Connecting switches to patch panels in small racks or cabinets
• Linking wall outlets to desktop PCs or single network devices
• Short connections between network equipment in home or office environments
• Situations requiring improved EMI protection compared with UTP cables

Key specifications

• Category: Cat5e
• Shielding: SF/UTP (S-FTP) — overall foil with individually shielded pairs
• Connectors: RJ-45 plug to RJ-45 plug
• Length: 1 m
• Color: Blue
• Data rates: suitable for 100 Mbps and 1 Gbps links depending on equipment

How to use

Plug each RJ-45 end into the corresponding network ports on your devices, for example between a switch and a patch panel or from a wall outlet to a computer. Ensure connectors are fully inserted until the latch clicks to guarantee a reliable connection. Keep the cable routed without sharp bends and avoid tight loops or kinks that could degrade performance. For best results with shielded cable, maintain proper grounding of the connected network equipment and racks if shielding continuity is required.

Recommendations

Use this 1 m Cat5e SF/UTP cable for short patching runs where EMI reduction is desirable. Avoid running the cable parallel to high-voltage power lines for long distances and ensure connector strain relief is not obstructed. If full 1 Gbps performance is needed across multiple runs, verify that all intermediate devices and ports support Gigabit Ethernet.
