As for these two types, there still are many subbranches for choosing. Take the fiber patch panel as an example, you can find regular fiber patch panels and enclosures, MTP/MPO cassettes and enclosures, fiber adapter panels and enclosures, MTP-LC breakout patch panels, etc. For different needs, you can choose the corresponding patch panel.

Horizontal Cable Manager

The horizontal cable manager is mostly applied in the 1U cable management, the height of data center racks of the standard unit (1.75 inches). Conventionally, it is installed in front of the server rack, ensuring cables being well-organized and protected. Altogether, there are four common types of 1U horizontal cable manager in the market: horizontal cable managers with finger duct, D-ring, brush strip, and the L-shaped horizontal cable manager.

Vertical Cable Manager

Apart from patch panel and horizontal cable manager, the vertical cable manager is another important branch of cable organizers. Similar to the horizontal type, the vertical type is also used to secure, bundle and route the cables at both sides of the server racks. However, unlike the horizontal cable manager, the vertical cable manager provides a vertical pathway for cables from switches to patch panels in the rack system. Among various vertical cable managers, 5U plastic vertical cable manager with bend radius finger, single D-ring vertical cable manager, and 45U 4.9″ wide plastic vertical cable manager are the popular applications.
