Networking cable EFB Elektronik EC020200257 RJ-45 Cat8.1 1 m Grey

The EFB Elektronik EC020200257 RJ-45 Cat8.1 1 m Grey networking cable is a short, high-performance patch cable designed for demanding wired networks. It uses Cat8.1 specification with S/FTP shielding to maintain signal integrity in environments with potential electromagnetic interference. The cable supports very high data transfer rates and is fitted with gold-plated RJ-45 connectors for consistent contact and reduced corrosion over time.

Advantages

The cable's S/FTP shielding (braided overall shield with individually foil-shielded pairs) reduces crosstalk and external interference, which helps preserve bandwidth and reduce packet loss. Its Cat8.1 rating enables multi-Gigabit and 25/40 Gbit/s network applications over short links. Gold-plated RJ-45 connectors provide stable contact resistance and improved durability compared to non-plated connectors. The 1 m length offers a compact, low-latency link suited to patch panels, switches and nearby devices without excess cable slack.

Suitable for

• Short-distance high-speed uplinks between switches, routers and servers
• Patch connections in data centers and server racks
• Workstation-to-switch connections where maximum throughput is required
• Environments with moderate electromagnetic interference where shielding is beneficial

Key specifications

• Category: Cat8.1 performance class
• Shielding: S/FTP (overall braid with individually foil-shielded pairs)
• Maximum supported data rate: up to 40000 Mbit/s
• Connectors: RJ-45 to RJ-45, gold-plated contacts
• Length: 1 m
• Colour: Grey

How to use

Connect one RJ-45 connector to the network port of a switch, router or network interface on a server or workstation and insert the other connector into the corresponding port on the target device. Ensure connectors are fully seated until the latch clicks to maintain a reliable connection. For best performance, avoid sharp bends and excessive tension on the cable and keep it separate from high-power electrical cables to minimise interference.

Recommendations

Use this 1 m Cat8.1 cable for short links within racks or between adjacent devices. For longer runs, choose appropriately rated cabling to maintain high-speed performance. Inspect connectors periodically and replace the cable if insulation or connector integrity is compromised.
