Sieťový kábel EFB Elektronik EC020200255 RJ-45 Cat8.1 0,25 m sivý

The EFB Elektronik EC020200255 RJ-45 Cat8.1 networking cable is a 0.25 m grey patch cable engineered for short-run, high-bandwidth connections. Built to Cat8.1 specifications, it supports data transfer rates up to 40000 Mbit/s and is fitted with RJ-45 connectors featuring gold plating. The cable uses S/FTP shielding to minimise electromagnetic interference and crosstalk, ensuring stable signal integrity in environments with multiple adjacent cables and active network equipment.

Advantages

The cable's Cat8.1 construction and S/FTP shielding provide high-frequency performance and reduced interference compared with lower-category cables. Gold-plated RJ-45 connectors improve contact reliability and resist corrosion, while the short 0.25 m length reduces latency and signal loss in close-proximity connections. The grey jacket offers a neutral visual appearance for tidy installations in racks, workstations, and networking panels.

Suitable for

• Short-distance connections between network devices in racks and server cabinets
• High-speed links for switches, routers and network interface cards supporting multi-gigabit traffic
• Point-to-point connections in home or small office setups where minimal cable slack is desired
• Environments with potential EMI where S/FTP shielding improves reliability

Key specifications

• Category: Cat8.1 — designed for high-frequency, multi-gigabit networking
• Maximum data rate: up to 40000 Mbit/s
• Cable length: 0.25 m
• Shielding: S/FTP (overall braid with individually shielded pairs)
• Connectors: RJ-45 on both ends with gold-plated contacts
• Colour: Grey

How to use

Connect each RJ-45 end to the corresponding ports on networking devices such as switches, routers or NICs. Ensure ports support the intended speeds and duplex settings. For optimal performance, avoid tight bends and excessive tension on the cable; maintain recommended bend radius and route the cable away from large sources of electrical noise when possible. For short runs like 0.25 m, verify secure seating of connectors until the latch clicks to prevent intermittent contact.

Recommendations

Use this Cat8.1 patch cable for short, high-performance links where minimal cable length is required. Pair it with compatible Cat8-capable hardware to achieve the specified transfer rates, and confirm proper port configuration on network devices. For long-distance runs choose appropriately rated longer cables and professional cable management to preserve signal quality.
