Cisco 3560X/3750X Four-Port Gigabit Ethernet Network Module, C3KX-NM-1G

When it comes to distributing fast signals across long distances, Cisco has a number of technology options available. One of them is the Cisco 3560x/3750x four-port Gigabit Ethernet module.

While it sounds like a mouthful, this module is designed to make networking approachable. It is energy efficient, secure, and scalable. It’s easy to use and reliable. You can easily connect your Ethernet switches to fiber via SFP connectors with this simplified module.

Making Networking Easier

When Cisco steers into ease of use, they really get it. The 3560 series is backward compatible with the 3750 series, making it easier than ever to connect the two.

SFP modules exist for the sake of adding fiber connectivity to Ethernet tools. You can increase bandwidth, diversify network design, add new components, and otherwise tweak your entire network as needed, one module at a time. The modules provide an affordable, scalable way to safely move your network into the future.
