Network Fundamentals

Drag and drop the characteristic from the left onto the cable type on the right.

Drag & Drop
supplies conduit for PoE implementations
used for DWDM optical systems spanning long distances
easy to tap into and obtain secure information
has a core diameter of 9 microns
copper
single-mode fiber
Explanation

Copper cabling can carry electrical power as well as data, which is why PoE runs over copper Ethernet cabling. Copper is also more susceptible to interception because its electrical signals can be tapped more easily than optical fiber. Single-mode fiber is designed for long-distance transmission, is commonly used with DWDM, and typically has a core diameter of about 9 µm.
