InLine ISDN kabel RJ45 samec samec 8P8C 20 m černý

The InLine ISDN Cable RJ45 male male 8P8C 20m Black is a 20‑metre network cable with RJ‑45 (8P8C) connectors on both ends, designed for ISDN and other Ethernet-based data connections. The cable's length and standardized RJ‑45 terminations provide a stable physical link for voice and digital data transmission in office and industrial environments. The black jacket offers a discreet, professional appearance and basic protection against everyday wear.

Advantages

This InLine cable provides a fixed 20 m reach without splices or adapters, reducing potential signal interruptions. Standard RJ‑45 8P8C connectors ensure compatibility with ISDN terminals, routers, switches and patch panels that accept modular Ethernet plugs. The single continuous conductor run maintains consistent electrical characteristics across the full length, supporting stable data transfer. The black outer sheath helps the cable blend into racks and cable runs while offering basic mechanical protection.

Suitable for

• Connecting ISDN terminals and ISDN network equipment over a 20 m distance
• Linking routers, switches or patch panels in office network installations
• Temporary or permanent cabling in server rooms, telecom closets or desktop setups

Key specifications

• Cable length: 20 m
• Connector type (both ends): RJ‑45 (8P8C)
• Number of connectors: 2 (male/male)
• Colour: Black
• Intended use: ISDN and Ethernet signal transmission

How to use

Route the cable between the two devices you wish to connect, avoiding sharp bends and tight cable ties that may stress the conductors. Insert each RJ‑45 male plug into the corresponding female RJ‑45 jack on your ISDN terminal, router, switch or patch panel until it clicks into place. Verify physical connection by checking link/activity LEDs on the connected equipment and perform any necessary network configuration on your devices. If running the cable through walls or ceilings, follow local regulations and use appropriate conduit or cable management to maintain protection.

Recommendations

For consistent performance, keep the cable away from high‑power electrical lines and strong electromagnetic sources. Avoid repeated bending near the connector ends; secure the cable with Velcro straps rather than tight plastic zip ties to prevent damage. Replace the cable if the jacket or connectors show visible signs of wear or corrosion.
