Everything has two sides, similarly, fine diameter network cable can not be without any shortcomings and drawbacks. The more obvious disadvantages of the fine diameter cable are the high DC resistance and insertion loss, which limits the transmission distance of the cable.

The DC resistance of a network cable measures the ability of the network cable to resist the current flow. The DC resistance is affected by the length and diameter of the network cable. The longer the network cable, the larger the DC resistance is. Therefore, the DC resistance of the fine-diameter network cable is greater than that of the ordinary network cable.

According to IEEE standards, the DC resistance on a transmission link should be 25 ohms (Ω) or less, and the new TIA 568.2-D standard recommends that when a 28 AWG fine-diameter cable is used in the link, the transmission distance must be kept within 15m, so that the DC resistance can be kept within 25 Ω.

The insertion loss is also an important performance parameter to measure the quality of the network cable. Like the DC resistance, the insertion loss of the network cable is also affected by the diameter and length. Under normal circumstances, the smaller the diameter of the network cable, the greater the insertion loss, and because the insertion loss is directly related to the length of the link, the total length of the link must be taken into account when using the fine-diameter network cable. For example, the derating factor (reducing the link length to less than 100 meters is called derating) of a 28 AWG fine cable is 1.95, and a 100m network link needs to be reduced to 96 m - 90m link and 6m network cable. The following table shows the transmission distance of the 28 AWG fine diameter cable and the corresponding link values for reference.

Although the transmission distance of the 28 AWG fine cable is limited, most users do not need to worry about this problem, because the fine cable is mainly deployed in the high-density cabling area of the data center, and the 90m link distance is more than enough for the high-density cabling area of the data center.

In addition to the above shortcomings to be considered before selecting the fine-diameter cable, its safety and reliability are more factors to be considered. The FS fine diameter network cable uses pure copper conductor. The FS fine diameter network cable has higher safety and overall performance than other copper-clad aluminum network cables. The FS fine diameter network cable has passed the UL and RoHS certification, and meets the requirements of high security and reliability for network connections.
