High-density cabling in the data center is increasingly associated with racks and a wide variety of junction boxes because the rack and junction box can be used to manage the cabling system and protect the fiber from external mechanical damage. However, only the choice of the appropriate rack and wiring box and the correct use can achieve the above results. This tutorial will detail the types of data center racks and junction boxes to help you choose the most suitable rack and junction box solutions.

Type of racks used in data center

The data center rack, also called the IT rack, is an open rectangular frame that is used to place network equipment and manage a wide variety of cables (see below). Now, as the data center becomes more complex, the racks have been given more functionality and played an important role in the structured cabling of the data center. As a result, different functional data center racks also have different design styles.

The data center rack is typically 19 inches wide and 42U high (about 73.5 inches), but its designs and features are varied. The following figure is the three types of rack types common to the data center: the following are the common three types of racks used in the data center:   

Standard double column 42U rack (with casters)  

Standard four-post 42U rack (no casters) 

Standard four-post 42U rack (with casters)

In the purchase of the rack, in addition to considering the rack style, we also need to pay attention to the following factors:

Flexibility and manageability: To build an easy-to-manage and flexible cabling system, you should first set aside enough space for future network expansion, so the rack size should be large enough. In addition, if you often need to move the rack, it is best to buy a rack with casters.

Adequate load capacity: We know that as people demand more and more bandwidth, the number of servers, power distribution equipment, brackets, cables and so on in the rack will be more and more, so the rack must have enough Of the load to support these devices.

Cooling efficiency: Now, the data center cooling costs are getting higher and higher, so choose a fast cooling rack is essential, with air management blind plate rack can effectively reduce the temperature inside the rack. In addition, the rack panel design is also closely related to the cooling performance of the rack, most of the rack panels are more than 64% of the hollow design to facilitate air circulation.

Safety: Some of the equipment in the data center is susceptible to external mechanical damage, so the top and bottom sides of the rack should be fitted with a panel (see below). Depending on the application, the various panels of the rack are also designed in a variety of ways.

Fiber distribution boxes for different applications

Another important part of the data center cabling is the fiber optic junction box. Typically, the fiber junction box is also a 19-inch width design, so it can be installed on a standard data center rack. In addition, users can also according to specific needs in the fast fiber (Feisu.com) custom fiber optic distribution box products.

The size and design of the fiber junction box are varied. Depending on the application, the fiber distribution box can be equipped with different fiber accessories. In general, the fiber distribution box can be installed inside the three accessories: splice tray, bobbin, and MTP wiring box. The following is a quick fiber (Feisu.com) 1U pull-type fiber optic junction box (pictured above) as an example to introduce a different optical fiber accessories wiring box.

Application 1: Load fiber splice tray and adapter panel

Typically, the 1U pull-out fiber optic junction box front panel can be installed four fiber optic adapter panel, the box can be installed one or more fiber splice disk. This design of the optical fiber junction box suitable for the need for on-site welding fiber applications can effectively protect the fiber fusion point.

Application 2: Load spool and adapter panel

This front panel has four fiber optic adapter panels, the box has two spools, is a pre-terminated fiber optic junction box, can greatly save the installation time and labor costs.

Application 3: Load-HD-MTP-junction-box

1U pull-out fiber junction box can be installed up to 4 MTP wiring box, to achieve MTP trunk wiring and LC wiring system smooth transfer, is 10G to 40G / 100G high-density wiring the ideal solution.
