The difference between Super Category 5 unshielded network cable and Super Category 5 shielded network cable

　　There are obvious differences in structure and performance between Super Category 5 unshielded network cables and Super Category 5 shielded network cables. The following is a detailed comparison of the two:

　　First, structural differences

　　Super Category 5 unshielded network cable

　　Structure: Consists of pairs of copper wires insulated from each other, which are twisted around each other in the form of twisted pairs to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). The outer layer is wrapped with a plastic skin to protect the wires inside.

　　Appearance: Usually there is only one layer of plastic skin, with no additional shielding.

　　Super Category 5 shielded network cable

　　Structure: In addition to the basic structure of the unshielded network cable, one or more layers of shielding materials are added to the outer layer of the twisted pair. These shielding materials can be aluminum foil, metal woven mesh, etc., to further reduce the impact of external electromagnetic interference on signal tranSMission.

　　Appearance: In addition to a layer of plastic skin, you can also see the internal shielding layer, such as metal woven mesh or aluminum foil.

　　Second, performance differences

　　Anti-electromagnetic interference ability

　　Super Category 5 unshielded network cable: Although some electromagnetic interference is reduced by the form of twisted pair, its performance may be affected in environments with severe electromagnetic interference.

　　Super Type 5 shielded network cable: Due to the additional shielding layer, it can more effectively resist external electromagnetic interference and ensure the stability and reliability of signal transmission.

　　Transmission rate and distance

　　Both support Gigabit Ethernet (1000Base-T) transmission and have similar transmission rates and transmission distances. However, in environments with severe electromagnetic interference, Super Category 5 shielded network cables may be more able to maintain stable transmission rates and longer transmission distances.

　　security

　　For environments with high data security requirements, such as finance, medical care, and other fields, the Super Five shielded network cable can provide better data transmission security.

　　Flame retardancy

　　Both should meet relevant flame retardancy standards, such as the UL94V-0 rating standard. This means that in the event of a fire, they can stop the spread of the fire to some extent.

　　III. Application scenarios

　　Super Category 5 unshielded network cable

　　It is suitable for environments with less electromagnetic interference, such as home networks, small offices, etc.

　　The price is relatively low, and installation and maintenance are also easier.

　　Super Category 5 shielded network cable

　　It is suitable for use in environments with severe electromagnetic interference, such as near substations, large machinery, or radio towers.

　　It is also suitable for places with high data security requirements, such as finance, medical care, and other fields.

　　IV. Purchase suggestions

　　Choose according to your needs: When purchasing, you should choose the appropriate network cable type according to your specific application needs and scenarios. If there is less electromagnetic interference in the environment, you can choose an unshielded network cable; if the electromagnetic interference in the environment is serious or there are high requirements for data security, you should choose a shielded network cable.

　　Check the product logo: When purchasing, check the logo on the network cable to confirm that it is a super-five network cable and whether it is a shielded or unshielded type.

　　Check quality: Check whether the appearance of the network cable is flat and smooth, and whether the shielding layer (if applicable) is intact and undamaged. At the same time, a small section of the network cable can be intercepted for combustion test to observe whether its flame retardant performance meets the standard.

　　Select a brand: Prefer products from well-known brands, whose product quality and after-sales services are more guaranteed.

　　To sum up, there are significant differences in structure and performance between Super Category 5 unshielded network cables and Super Category 5 shielded network cables. When purchasing, the appropriate network cable type should be selected according to specific needs and environments.
