Overview

The Elfcam Cat 7 Ethernet cable is a 20-meter shielded LAN cable designed for high-speed wired networking. It features 100% bare copper conductors and gold-plated RJ45 connectors, supporting data transfer rates up to 10Gbps with a bandwidth of 600MHz. The SFTP (Screened Foiled Twisted Pair) construction minimizes electromagnetic interference, ensuring stable signal transmission. Ideal for home or office environments where Wi-Fi is unreliable or where long cable runs are needed.

Connectivity & Compatibility

This cable uses standard RJ45 connectors and is compatible with any device that has an Ethernet port, including routers, switches, PCs, gaming consoles, and NAS devices. It supports 10/100/1000/10000BASE-T, making it suitable for both legacy Gigabit networks and modern 10GbE setups. The SFTP shielding provides extra protection in electrically noisy environments, such as near power cables or industrial equipment.

Product Info

The Elfcam Cat 7 20m cable is widely available on Japan. Priced around ¥23,000, it offers a cost-effective solution for long-distance cabling. The cable comes with a 10-year warranty, reflecting confidence in its build quality. No accessories are included beyond the cable itself. Market positioning: mid-range, balancing performance (pure copper, SFTP shielding) with affordability compared to premium brands like Belkin or Cable Matters.

Best Use Cases

Home users seeking reliable wired connections: Perfect for eliminating Wi-Fi dead zones or for connecting devices far from the router. The 20m length allows routing through walls or ceilings. However, if you only need a short cable, this length is overkill. Office or small business installations: Ideal for running cables across rooms or floors. The SFTP shielding reduces interference from office equipment. Not recommended for frequent plugging/unplugging; it's designed for permanent installation. * 10Gbps network builders: The Cat 7 standard supports 10GbE, making this cable future-proof for high-speed LANs. But you'll need compatible switches and NICs to take advantage. In a Gigabit-only network, Cat 6 would suffice.

Things to Consider

The cable is 6.0mm thick and 28 AWG, which may be difficult to route through tight conduits or corners. Measure your path carefully. Cat 7 is not officially recognized by TIA/EIA; in practice, Cat 6A often matches its performance. However, the SFTP shield provides better noise immunity. Ensure the cable is pure copper (not CCA) for best signal integrity. This model is advertised as 100% copper. The 20m length is generous; consider if a shorter (or longer) cable fits your needs better. ## FAQ
Q: Can I use this cable with my PS5 or Xbox? A: Yes, it works with any RJ45-equipped gaming console, providing a stable wired connection for online gaming. Q: What's the difference between Cat 6 and Cat 7? A: Cat 7 offers 600MHz bandwidth and native 10Gbps support, while Cat 6 is limited to 250MHz and 1Gbps (Cat 6A goes to 500MHz/10Gbps). Cat 7 also uses SFTP shielding for better noise resistance. Q: Does the 20m length cause signal loss? A: Cat 7 is rated for 10Gbps up to 100m, so 20m is well within spec. Signal loss is negligible with a quality cable.
