Length Guidelines
The maximum length of a channel depends on the de-rating factor of the cabling components within the channel
(patch cords, equipment cords, and horizontal cabling). Panduit horizontal cable has a de-rating factor of 1.
Panduit 24 AWG patch cords have a de-rating factor of 1.2. All Panduit 28 AWG patch cords have a de-rating
factor of 1.9.
The maximum length of a channel (in meters) is calculated by:
(De-rating of patch * Patch Length) + (De-rating of horizontal * Horizontal Length) < 102 m.
This equation supports the following example channel lengths and configurations using Panduit 28 AWG
patch cords:
Channel length with a 90-meter permanent link
• 6 meters of total 28 AWG patch cord length
• 90 meters of total horizontal cable length
• 96-meter channel length
Channel length with 10 meters of 28 AWG patch cords
• 10 meters of total 28 AWG patch cord length
• 83 meters of total horizontal cable length
• 93-meter channel length
Channel length of 100 meters
• 2 meters of total 28 AWG patch cord length
• 98 meters of total horizontal cable length*
• 100-meter channel length
* Note: 98 meters will not pass Permanent Link testing with a field tester; however, the total
channel will pass channel testing and Ethernet traffic.
These channel configurations employing Panduit 28 AWG patch cords will exceed all Category 6A,
Category 6, and Category 5e performance requirements defined in ANSI/TIA-568.2-D and ISO11801.
