Understanding the Modular Patch Panel

Cable management is a significant part of a network which is designed well. Managing cables have contributed to maintaining the essential function of data centers and protect devices from airflow blockages caused by unorganized and disordered cables. Therefore, users usually solve cabling problems with fiber patch panel, splicing fiber enclosure, server rack and other cable management methods. Among them, fiber optic patch panel is an economical, efficient and easy-to-use cable management solution for the modern data center. However, depending on different standards, there are different types of patch panels. Today, our topic is one kind of patch panels: the modular patch panel.

What Is Modular Patch Panel

The modular patch panel, or unloaded patch panel, is a kind blank fiber patch panel without pre-loaded built-in ports. But the modular patch panel has reserved holes. The empty slot allows users to install different ports according to his needs, such as CAT5E/CAT6 insertion module. Therefore, these panels can terminate different cables when different connectors are required to be installed. In addition, a modular patch panel can connect multiple types of cables. Generally, the modular patch panel is installed in the high-density 1U rack. It can be easily installed on the standard racks, cabinets or wall brackets. All empty ports are also numbered in advance to facilitate connection and identification.

Flat and Angled Modular Patch Panel

According to the style of design, the modular patch panel includes two types: flat modular patch panels and angled modular patch panels. I’ve once seen the jokingly stated that the difference between the flat panel and angled panel is the aesthetic difference. In fact, the most essential difference between the flat modular patch panel and angled modular patch panel is indeed the shape, the former is straight, and the latter has a “V” angle.

Flat modular patch panels help horizontal cable managers organize and route cables to vertical managers. The angled patch panels facilitate cabling improvement. They are substitutes for management and do not require horizontal management of rack space. The angled patch panels increase the rack density and manage high-density applications in a quarter of the area required for conventional cable management systems. However, due to the requirement of front depth, the angled patch panels are not conducive to the installation of cabinets.


The modular patch panel is useful for eliminating cable clutter, leaving enough room for airflow, and maximizing the performance and scalability of the data center. Today’s data centers need a reliable, scalable, and manageable cabling infrastructure, and then patch panel cable management solutions address these trends and promote high-density data center cabling efficiency. By the way, when buying patch panels, there is no single solution that meets all cable management needs. We hope you can get a little knowledge of patch panel cable management technology to successfully deploy cables in the data center. FS.COM can provide you with not only many kinds of fiber patch panels, but also fiber enclosures and server racks which support your cable managing work.

How to Achieve Efficient High Density Cable Management

For some data center professionals, organizing cables and devices with high density enclosures can be a stressful and time-consuming chore. However, one can never ignore or underestimate the importance of the structured and organized cabling system. Fortunately, thanks to the flexibility of new enclosure designs, a standard for organizing enclosure space, as well as power and data cables can be easily implemented. In this article, we will explain the significance and benefits of efficient high density cable management and provide a five-step guidance towards how to achieve this goal.

Why High Density Cable Management Matters?

Data center managers and operators may have realized the fact that crowded enclosure and cable mess would pose potential threat to overall network reliability, not only on efficiency and uptime, but also on the overall look and feel of the data centers. It is generally accepted that data center efficiency is driven by energy consumption, which is closely related to the structure and organization of the cables in each enclosure. Therefore, cable management in high density cable environment plays a significant role in determining whether the network can operate smoothly and efficiently. In addition to that, the overall appearance and circumstance of your cabling system generally indicates the cleanliness and professionalism of the entire data center.

Benefits of High Density Cable Management

After talking about the necessities and importance of managing equipment and cabling inside of the enclosure. Let’s move to what we are supposed to benefit from an organized and optimized high density cabling system.

Proper management of high density data and power cabling within an enclosure will deliver various benefits that will enhance your system availability and improve your bottom line.

Reduced signal interference—the elimination of crosstalk and interference between cables will enhance system performance.

Improved maintenance and serviceability—easier access to internal rack components reduces maintenance time and improves safety.

Cooler performance—cooling efficiency within the rack is enhanced thanks to proper positioning of cables to avoid air flow blockage.

A roadmap for growth—effective cable management solutions provide the ability to scale and adapt to changes in the IT infrastructure while minimizing service time.

Five Steps for Efficient High Density Cable Management

In this part, we will illustrate five essential steps for facilitating the goals of improved and efficient high density cable management.

Step 1. Plan for higher density

In most cases, two distinct enclosure configuration scenarios can be adopted to high density cabling system. The first consists of an enclosure populated with 1U / 2U servers. The second consists of an enclosure with blade servers. So firstly, an appropriate enclosure environment needs to be assessed. When planning, the first element to consider is whether any of the existing data center enclosures are suitable candidates for hosting higher densities.

Step 2. Calculate enclosure power requirement

Before deploying the specific kind of fiber enclosure, one must determine the maximum power required per enclosure. The estimated power requirement will dictate the particular input power cord and plug configurations needed for the enclosure. All PDUs should have the ability to meter the input current at the branch circuit breakers. This allows the user to determine whether the circuit is approaching the maximum capacity or whether imminent danger of a circuit breaker tripping exists.

Step 3. Select proper enclosure size

For higher density situations, an enclosure either wider than the 24 inch (600 mm) or deeper than the 42 inch (1070 mm) is chosen to provide the space needed for organizing additional data and power cables inside the enclosure. Wider enclosures are now considered a logical choice for higher density server applications. Overall, the wider enclosure provides the most flexibility for equipment and cable organization. Deeper enclosures become an option when the uniqueness of the floor layout dictates a deeper rather than a wider enclosure or when more than two rack PDUs are required.

Step 4. Implement smart cable management

The most effective method for managing cables in high density environments is to implement patch panels or switches dedicated to cabling for a particular row of enclosures. These patch panels or small switches will be terminated back to the core switch or router feeding its section of the data center. The core switch is typically located in another enclosure. This approach is effective because it separates the cabling inside the enclosure from the rest of the data center cable load.

Step 5. Organize for efficient cooling

A simple solution is to install airflow management blanking panels to cover all unused U spaces. Airflow management blanking panels are tool-less and quick and easy to install. In addition, many enclosures have cutouts or other features to route cables from the front to the rear of the enclosure. If these air management features are unused, they can introduce access paths for hot air to enter and circulate inside the enclosure. These cutouts must be closed with panels or grommets to optimize for high density air flow patterns.

Today’s high density rack-based IT server and switching installations provides higher and higher levels of performance and capacity. Therefore, to achieve efficient high density cable management becomes even more important since massive cable must be managed within these tightly spaced rack environments. Hope the five steps we mentioned above could help to manage and optimize your cables and infrastructures.
