## Long description

EFB Elektronik K8054.40 is a 40 m S/FTP (S‑STP) shielded Ethernet patch cable with RJ‑45 connectors on both ends and gold‑plated contacts. Designed for data rates up to 10 000 Mbit/s (10 Gbps), the cable features individually foil‑shielded twisted pairs plus an overall braided shield to minimise electromagnetic interference and maintain signal integrity in LAN, server and data‑centre environments. The cable’s blue jacket and standard RJ‑45 termination make it compatible with switches, routers, network interface cards and patch panels that support 10 Gigabit Ethernet.
Advantages
The S/FTP (S‑STP) construction provides both pair-level foil shielding and an overall braided shield for enhanced protection against crosstalk and external EMI. Gold‑plated contacts on the RJ‑45 plugs improve corrosion resistance and ensure reliable electrical contact over repeated insertions. With a 40 m length and support for 10 Gbps throughput, the cable allows flexible placement of network equipment without performance compromise. The jacket colour simplifies visual identification in structured cabling installations.
Suitable for
 10 Gigabit Ethernet links in local area networks
 Connections between servers and switches or patch panels
 Backbone and horizontal cabling in data centres and server rooms
 Environments with elevated electromagnetic interference where shielded cabling is required
Key specifications
 Cable type: S/FTP (shielded overall braid with individually foil‑shielded pairs)
 Connector type: RJ‑45 to RJ‑45 with gold‑plated contacts
 Length: 40 metres
 Maximum data rate: up to 10 000 Mbit/s (10 Gbps)
 Colour: blue jacket
 Application: suitable for LAN, server connections and data centre backbone cabling
How to use
Route the cable between network ports on switches, routers, servers or patch panels, avoiding sharp bends and contact with sources of strong electromagnetic fields where possible. Insert RJ‑45 plugs fully into the mating ports until a tactile click is felt. For optimal performance, ensure proper strain relief at termination points and avoid running the cable in parallel with high‑voltage power lines. When connecting 10 Gbps devices, verify that both endpoints and intermediate hardware support the required speed and shielded cabling to maintain signal integrity.
Lietošana ieteikumi
Store and handle the cable in a dry, dust‑free environment and perform visual inspections of the RJ‑45 contacts before installation. In installations requiring maximum EMI protection, ensure that connectors and patch panels provide continuity of the shield to grounding points.
