A CAT5 patch cable is a type of Ethernet cable commonly used for networking purposes. "CAT5" stands for Category 5, which refers to the cable's performance specifications. It supports data rates up to 100 Mbps and frequencies of up to 100 MHz. "Patch cable" indicates that it's designed for temporary or permanent connections between network devices, such as computers, routers, switches, and other network equipment.
The "15M" in your query likely refers to the length of the cable, which is 15 meters. This length indicates how far you can physically connect two network devices using this cable while still maintaining signal integrity.
Lastly, "copper" specifies the material used for the cable's conductors. Copper is a common choice for Ethernet cables due to its excellent conductivity and durability.
In summary, a CAT5 patch cable with a length of 15 meters and made of copper is suitable for connecting network devices within a moderate distance, typically in office or home networking setups.
