In a previous blog, we covered what to do when you need to connect a device that is located beyond the 100-meter distance requirement and described four ways to address the problem—a new TR, the use of an extender device, extended-reach copper cable and fiber.
When using fiber to go beyond the distance, devices that do not include a fiber input/output require some form of media conversion, and if that device also needs power over Ethernet, it takes a media converter. Devices that include a fiber connection and power terminals for DC power can connect via hybrid copper-fiber cable, sometimes referred to as composite cable. This does of course require the use of fiber transceivers for data transmission and a power source capable of delivering low-voltage DC power over the copper conductors.
