Patch kábel LAN Extralink Cat.7 S/FTP 0,5 m 20G, zelený, medený krútený pár (EX.38749)

Extralink Cat.7 S/FTP patchcord, 0.5 m in green, is a shielded copper twisted-pair cable designed for short high-speed LAN interconnections between switches, routers, patch panels and network devices. The cable supports transmission rates up to 20 Gb/s and operating frequencies up to 600 MHz, while individual pair shielding plus an overall shield provide effective protection against electromagnetic interference and crosstalk. Gold-plated shielded connectors and pure copper conductors ensure reliable contact and support for PoE-enabled devices where power delivery over Ethernet is required.

Advantages

The Extralink Cat.7 S/FTP patchcord delivers higher bandwidth and improved EMI protection compared with lower category cables. Its construction — four pure copper twisted pairs with individual pair foil shields and an overall braided/foil shield — reduces signal degradation and external interference. The short 0.5 m length is convenient for tidy server racks, patch panels and dense networking environments. Durable materials and shielded connectors increase long-term reliability and maintain stable connections under load.

Suitable for

• Short connections between network equipment in server rooms and data cabinets
• Patch panels and rack-mounted switches in office networks
• High-bandwidth links for 4K/8K video distribution and media streaming
• Environments where electromagnetic interference (EMI) mitigation is required

Key specifications

• Cable category: Cat.7 (S/FTP shielding — screened foil around each pair plus overall screen)
• Length: 0.5 m
• Conductor material: pure copper, four twisted pairs
• Maximum supported data rate: up to 20 Gb/s (over specified distances)
• Frequency range: up to 600 MHz
• Connector plating: gold-plated shielded RJ45 connectors
• Color: green
• PoE support: compatible with Power over Ethernet standards

How to use

Plug one end of the patchcord into the RJ45 port of a network device (for example a switch or router) and the other end into the target device or patch panel. Ensure connectors are fully inserted until they click and that the cable routing avoids sharp bends and heavy compression which can damage shielding and pairs. For rack installations, use appropriate cable management to keep the 0.5 m patchcord neat and to minimize stress on connectors. Verify link speed and PoE operation through the connected devices' status indicators or management interface.

Recommendations

Use this Cat.7 S/FTP 0.5 m patchcord for short, high-performance links where EMI protection is important. Avoid running the cable alongside high-voltage power lines; keep bend radius at or above the manufacturer's minimum to preserve signal integrity. For long-distance backbone connections choose longer Cat.7 cables or appropriate structured cabling designed for full-distance runs.
