Networking cable ROLINE Recycled Material 21.45.3219 RJ-45 Cat6a 20 m Red

The ROLINE Recycled Material 21.45.3219 is a 20 m Cat6a networking cable with shielded RJ-45 connectors designed for 10 Gigabit Ethernet. Constructed using recycled materials, this red cable combines high-speed data transmission with reduced electromagnetic interference thanks to S/FTP shielding and durable gold-plated contacts.

Advantages

S/FTP shielding minimises crosstalk and external interference for stable 10GBase-T performance. Gold-plated contacts provide reliable signal transfer and corrosion resistance. Moulded bend protection at the connectors increases mechanical durability and prolongs the cable's service life. The use of recycled materials reduces environmental impact while maintaining required Cat6a specifications.

Suitable for

• 10 Gigabit Ethernet networks (10GBase-T)
• Server rooms and data centres requiring shielded cabling
• High-speed workstation and uplink connections
• Structured cabling installations where Cat6a performance is needed

Key specifications

• Standard: Cat6a
• Connectors: RJ-45 to RJ-45
• Shielding: S/FTP (screened foiled twisted pair)
• Colour: Red
• Manufacturer MPN: 21.45.3219
• EAN: 7630049631373

How to use

Connect one RJ-45 connector to your network device (switch, router, or NIC) and the other to the corresponding port on the remote device. Ensure connectors are fully inserted until the latch engages. Route the cable avoiding sharp bends and sources of strong electromagnetic interference for optimal performance. For rack installations, secure the cable with appropriate management accessories to prevent strain on the connectors.

Recommendations

For consistent 10GBase-T transmission, use this Cat6a S/FTP cable for links up to 100 metres in compliant structured cabling environments. Avoid tightly coiling or kinking the cable and keep it separate from high-voltage power lines to maintain shielding effectiveness.
