What this cable is and who it serves

The Belkin A3L791-30-S is a 30 ft Category 5e patch cable with RJ45 connectors on both ends. It links computers, routers, switches and other LAN devices in home or small-office networks. The gray, unshielded design suits standard indoor runs where electromagnetic interference is low. Buyers needing longer distances, outdoor rating or shielded construction should look elsewhere.

Behaviour under sustained load

Rated for 10/100 Base-T networks, the cable maintains reliable throughput for everyday file transfers, web browsing and streaming across its full 30 ft length. Cat 5e specifications support the signalling rates required by 100 Mbps Ethernet without signal degradation over this distance. It is not rated for gigabit or multi-gigabit operation, so sustained high-bandwidth workloads will be limited by the category ceiling.

Build quality and daily implications

The moulded RJ45 plugs feature standard latch tabs that click into Ethernet ports on PCs, routers and switches. The unshielded twisted-pair jacket is flexible enough to route around corners and through cable-management channels. Gray colour coding helps identify the link in a crowded patch panel. A lifetime limited warranty from the manufacturer covers defects in materials and workmanship.

Questions about this item

Does the 30 ft Cat 5E cable generate any heat or noise when carrying data all day?

No, the cable is passive copper with no active components, so it produces no heat or noise during continuous use.

What devices must I already have to use the RJ45 connectors on this patch cable?

You need two devices with RJ45 ports — such as a router, switch, PC or console — to plug each end into.

Will this Cat 5E cable work alongside the older Cat 5 cables I still have in the house?

Yes, it is backward compatible with Cat 5 and will run at 10/100 Base-T speeds on that legacy wiring.
