Product information

Description

The EFB Elektronik K5528BL.5 is a Cat8.1 RJ-45 patch cable with a length of 5 m, designed for high-speed copper Ethernet connections. It supports 25GBASE-T and 40GBASE-T applications and offers transmission rates up to 40000 Mbit/s with a frequency range up to 2000 MHz and a maximum recommended patching distance of 30 m.

Advantages

The cable uses S/FTP (S-STP) shielding to reduce electromagnetic interference and crosstalk, ensuring stable signal transmission in demanding network environments. Its Cat8.1 specification and RJ-45 connectors provide backward compatibility with lower-speed Ethernet while enabling multi-gigabit and 40GBase-T connections. The 5 m length offers flexibility for rack-to-equipment or workstation connections, and the blue jacket makes cable identification easier in structured cabling.

Suitable for

25GBASE-T and 40GBASE-T rack patching and device interconnects
High-density server rooms and data center top-of-rack connections
Workstation or switch-to-switch links requiring short-run, multi-gigabit copper links
Environments where shielded cables are needed to minimise interference

Key specifications

Standard: Cat8.1
Connectors: RJ-45 to RJ-45
Cabling technology: 40GBase-T, compatible with 25GBase-T
Cable length: 5 m
Maximum data rate: up to 40000 Mbit/s
Frequency range: up to 2000 MHz
Shielding: S/FTP (S-STP)
Colour: Blue
Maximum recommended transmission distance (copper patch): 30 m

How to use

Connect each RJ-45 connector to the corresponding port on network devices such as switches, routers, or network interface cards. Ensure both ports support the intended link speed (25G or 40G) and that connected equipment is configured for the required duplex and negotiation settings. Route the cable to avoid sharp bends and sources of strong electromagnetic interference; secure with appropriate cable management to maintain performance and reduce mechanical strain on connectors.

Usage recommendations

Use this Cat8.1 S/FTP patch cable for short-distance, high-speed copper links in data centers and server rooms. Verify device compatibility for 25G/40GBase-T and keep runs within the recommended 30 m copper limit for reliable performance.
