CAT-5E and HSYV-5E are the same.

CAT-5E is a Category 5e network cable, and HSYV-5E is a Category 5e twisted pair. The two have different names, but they are used the same on the network, so they are the same thing. .

HSYV is the structure of the wire, HS is the classification code, which means horizontally twisted cable for digital communication, Y is the code for the insulating material, which means solid polyolefin, and V means polyvinyl chloride , cat is the abbreviation of the word category, which means classification.

Extended information:

Category 5e refers to Category 5e unshielded twisted pair (UTP—Unshielded Twisted Pair) and Category 5e shielded twisted pair. Unshielded Twisted-pair cables are composed of multiple pairs of twisted pairs and a plastic sheath.

Category 5 refers to five different quality levels for twisted-pair cables defined by the International Electrical Industry Association. Ordinary network cables are currently generally used. Refers to Category 5, so the quality of Category 5e network cables is higher than that of ordinary network cables. The twisting degree of the wire pairs in Category 5e network cables is denser than that of Category 5. It is generally used in Gigabit Ethernet (1000Mbps).
