Cable de red Alcasa 8080-250B Cat8.1 25 m azul

The Networking Cable Alcasa 8080-250B Cat8.1 25m Blue is a 25-meter network cable designed for high-speed data transmission in wired Ethernet installations. Built to the Cat8.1 specification with S/FTP shielding, this blue cable offers improved protection against electromagnetic interference and crosstalk. Both ends are terminated with RJ-45 connectors featuring gold-plated contacts to maintain reliable signal integrity and reduce corrosion over time. The cable supports data transfer rates up to 40000 Mbit/s and is intended for use in demanding local network environments where performance and shielding are required.

Advantages

Cat8.1 construction with S/FTP shielding provides superior protection against external interference and pair-to-pair crosstalk compared with lower-category cables. RJ-45 connectors with gold-plated contacts improve contact reliability and longevity. The 25 m length accommodates longer cable runs without significantly impacting signal quality within typical Ethernet limits. The blue outer jacket makes cable routing and identification easier in multi-cable installations.

Suitable for

• High-speed local area networks (LANs) requiring Cat8.1 performance
• Server rooms and data center interconnects over short-to-medium cable runs
• Workstations, switches, and network appliances that use RJ-45 interfaces
• Environments with potential electromagnetic interference where S/FTP shielding is beneficial

Key specifications

• Cable category: Cat8.1
• Shielding: S/FTP (overall shield with individually shielded pairs)
• Length: 25 m
• Connectors: RJ-45 to RJ-45
• Contacts: Gold-plated
• Color: Blue
• Maximum data rate: up to 40000 Mbit/s

How to use

Route the Alcasa Cat8.1 cable between network devices ensuring bend radius and handling follow standard practice for high-frequency Ethernet cables. Insert each RJ-45 connector fully into the corresponding Ethernet port until a secure latch click is felt. Avoid tight bends, sharp kinks, and crushing under heavy objects to preserve shielding and conductor integrity. For long installations, verify link negotiation and throughput on connected devices to confirm correct operation at the expected data rate.

Recommendations

For optimal performance, install the cable away from large power cables and strong EMI sources. Use proper cable management (cable ties, trays, or conduits) to prevent mechanical stress. When connecting to devices, verify that the network equipment supports the intended speeds and that patch panels or keystones are rated for Cat8.1 or compatible shielding to maintain end-to-end performance.
