D-Ring in Vertical Cable Management
When a D-ring is used for vertical cable management, it can be directly installed on the server rack using appropriate fasteners. It can be used for both front or rear cable management providing tidy cabling appearance and easy cable adding or removing in vertical cabling environment as shown in the following picture.
D-Ring in Horizontal Cable Management
The using of D-ring in horizontal cable management is more flexible and can be used with a wide range of cable management products for different applications. In most horizontal applications, D-ring is installed on cable management panels. Here introduce two of the most commonly seen applications of D-ring. The first one is using D-ring with patch panel, the second one is using D-ring with rack unit enclosures.
The following picture shows a simple example of fiber cabling using cable management panel with D-ring on the front panel, fiber patch panel installed on the IT rack and a lacing bar on the rear side. Four 24-fiber LC adapter panels are installed on the fiber patch panel. The cable management panel with D-ring is installed on the front side of this IT rack providing an organized channel for the fiber optic cables connected to the fiber adapter panels. Fiber cables connected to the rear side are supported by the lacing bar which provides cable strain relief.
The following picture shows an example of using D-ring with fiber enclosure. The cable management panel with D-rings in installed on the front side of the fiber enclosure. Every strand of fiber patch cable goes through the D-ring on the panel eliminating the dangling of cable and decreasing bend loss effectively.
