What is the maximum length for a permanent link horizontal cable?

The maximum length for a permanent link horizontal cable is 90 meters (295 feet). This specification comes from industry standards, particularly the Telecommunications Industry Association (TIA) standards, which set the maximum distance for horizontal cabling to ensure signal integrity and performance. The 90-meter limit includes the distance from the telecommunications room to the work area outlet, covering the cable length between the patch panel and the outlet in the workspace.

This limit is crucial for maintaining the required performance parameters such as bandwidth and attenuation of the signal, ensuring that the network operates efficiently without data loss or interference. It is also designed to complement the overall maximum length of the channel, which typically includes additional distances for patch cords.

In contrast, other lengths listed as options do not comply with these established standards for horizontal cabling and would surpass the effective range recommended for maintaining optimal network performance.
