The designation of a computer cable typically incorporates elements such as insulation material, conductor type, shielding method, and sheath material. Each component is named according to specific standards, using a combination of letters and numbers. Below is a detailed explanation of some standard computer cable model designations and their meanings:
DJYPV: This designation refers to a computer cable featuring polyethylene insulation, twisted copper wire pairs with braided shielding, and a PVC sheath. "D" stands for data cable, "J" indicates twisted pairs, "Y" denotes polyethylene insulation, "P" represents copper wire shielding, and "V" signifies a PVC sheath. If "P2" appears in the designation, it indicates copper tape shielding rather than copper wire shielding.
DJYVP: Compared to DJYPV, this type differs in the choice of shielding or sheath materials. Typically, the "P" following the letter "V" indicates a polyethylene sheath rather than PVC.
DJYPVP: This type of cable adds an extra layer of shielding to the DJYVP design, thereby providing superior protection against electromagnetic interference (EMI).
