What's the difference between double shielded Cat5e and double shielded Cat6 network cable?

There are double shielded cat5e and cat6 double chielded network cables. Double shielded network cables can be expressed by SFTP/SFTP: that is, double shielded twisted pair cable. On the basis of the aluminum foil of STP, a braided network is added, usually using aluminum magnesium wire braided network and tinned copper network.

The outer layer is PVC, in general, there are two layers of shielding layer, and there must be insulation between the two layers of shielding layer. Its advantage is to effectively reduce the environmental magnetic field, signal interference, the internal signal attenuation degree is low.The disadvantage is poor softness and expensive, this anti-interference and highly secure transmission wire, suitable for special environment of professional wiring engineering.
Shielded cable refers to the internal shielding layer of the cable, the shielding layer refers to aluminum foil and woven mesh.Single shield cable shield is only a layer of aluminum foil paper, double shielded cable outside the wire pair wrapped in a layer of aluminum foil, and a layer of metal mesh grid, double screen cable and the shielded cable is according to the environment of the use of different to distinguish, double shielded cable is mainly with strong interference environment, the shielded cable is used in ordinary everyday in the network environment.
(1) double shielding: cable and non-shielding cable from the internal structure is very easy to distinguish, double shielding cable internal is a layer of metal shielding net and a layer of aluminum foil, double shielding cable is also known as double screen with network line.There are only 4 pairs of cables inside the non-shielded cable.
What is the difference between 5 types of double shielded cable and 6 types of double shielded cable?
First, different transmission frequencies
1. cat6 Network Cable: transmission frequency is 250MHz.
2. cat5e network cable: transmission frequency is 100MHz.
Two, different uses

1, cat6 double shielded cable: suitable for transmission rate higher than 1Gbps applications, mainly used for gigabit Ethernet (1000Mbps).

2. Cat5e Shielded Network Cables: Used for voice transmission and data transmission with high transmission rate of 100Mbps, mainly used for 100BASE-T and 10BASE-T networks.
Third, different characteristics
1, cat6 network cable: in the shape and structure and five or super five kinds of twisted pair have certain differences, not only increased the cross skeleton insulation, the four pairs of twisted pair lines are placed in the four grooves of the cross skeleton, but also the diameter of the cable is thicker.
2. cat5e network cable: Ethernet cables are commonly used. This kind of cable increases the winding density and coats a kind of high quality insulation material.
All six types of twisted-pair have significantly improved parameters and expanded bandwidth to 250MHz or more. Cat6 of twisted pair have certain differences in appearance and structure with five or super five types of twisted pair, not only increase the cross frame of insulation, the four pairs of twisted pair are placed in the four grooves of the cross frame, but also the diameter of the cable is thicker.
