Fiber Cable Assembly Lengths
Proper measuring for QuickNet
™
Fiber Cable Assembly lengths is straightforward but does require some detailed information about
the data center layout. For the most accurate length measurements, it is best to work from layout drawings and know the specific
equipment to be used, the cabinet dimensions, and the desired positions in the cabinets of patch panels and equipment.
The illustration below shows a typical data center link and the sections that must be considered to properly measure for QuickNet
™
Fiber Cable Assembly lengths. This example shows an overhead in-row installation. For other configurations, adjust accordingly. (For
example, with underfloor configurations, measure down from the panels to the pathway).
Recommended Steps for Measuring QuickNet
™
Fiber Cable Assembly Lengths:
1. Calculate or measure the length of each section of the link.
a. Harness length: A1 + A2
b. Horizontal cable length: B + C + D
2. Round the total upward to the nearest foot to get the minimum QuickNet
™
Fiber Cable Assembly length.
Link Sections and Guide for Measuring:
In-cabinet length: The total length of the cable inside the cabinet (A1 + A2).
A1 – Horizontal distance from switch face to vertical manager – Panduit recommends 1m breakout or stagger to
allow for cable routing and management.
A2 – Distance from vertical manager to patch panel in cabinet – this can vary depending upon where the patch
panel is located within the cabinet.
Patch panel-to-pathway length: The distance from the patch panel in cabinet to the cable pathway.
Length along pathway: The total distance along the pathway between the cabinet entry/exit points.
Pathway-to-patch panel length: Similar to B.
