What is a Patch Panel in Networking?
ISO/IEC 11801:2002 defines a network patch panel as a wiring device suitable for patch cord connections. ANSI/TIA 568-B defines a patch panel as a cross-connection system consisting of easily managed pairs of connectors.
Network patch panel is centralized, convenient management, consisting of pairs of connectors, using patch cords for jumpering, for the connection of vertical and horizontal subsystems, or the connection of the bureau end for user information points. And can be centralized management of these cable systems, distribution, and adjustment of the wiring device.
The current market patch panel is generally a 24-port patch panel, with a length of 19 inches (482.6mm ± 0.5mm), a height of 1U (44.4 ± 0.1), and the color is black.
The front shell of the network patch panel is generally ABS plastic; according to Wikipedia information: ABS plastic has excellent impact resistance and can adapt to the possible impact of the patch panel during installation and 15 years of use. Has incredible high and low-temperature resistance, can be -40 ℃ to 93 ℃, and can meet the vast majority of the use of patch panels in the region of -20 ℃ to 70 ℃; In addition, ABS resin does not dissolve in the standard solution in life, can ensure that in use, not easy to be corroded; surface gloss, easy to color, electrostatic spraying, and other secondary processing, can be processed into a variety of different colors, to adapt to the diverse needs of the patch panel shell. In addition, ABS resin insulation is excellent, and its insulation performance is unaffected by temperature, humidity, and frequency, which can ensure that the link is not short-circuited to ensure effective signal transmission. In summary, ABS resin is a synthetic resin widely used in network patch panels.
The structure of the front end mainly has: an RJ45 jack and marking area. The marking area consists of a paper drawing strip and PE plastic divider. RJ45 jack is used for plugging network jumpers, the hole is arranged with eight “gold pins,” eight gold pins are generally staggered up and down, such an arrangement structure design can be as far as possible to separate the electrical signal, reduce the movement in the network patch panel when the interference.
The primary material of the “gold pin” is phosphor bronze. Phosphor bronze uses phosphorus to remove the oxygen from pure copper and bronze to achieve the characteristic effect of wear resistance. Phosphor bronze has strong wear resistance, can meet the information jack more than 750 times the plug test needs and impact resistance, and is not easy to produce sparks; it can meet the POE link jumper plugging needs. In addition, the maximum working temperature of phosphor bronze to 250 ℃ to complete the patch panel’s 20 ℃ to 70 ℃ use demand. Therefore, phosphor bronze is widely used in patch panels cell phones, computers, interactive devices, and other jacks.
However, phosphor bronze is a copper alloy, copper alloy in the air is easy to oxidation. Therefore, the patch panel manufacturers will use phosphor bronze for the whole nickel plating process because nickel in contact with air in a humid environment generates a dense oxide film to prevent further oxidation of the main body. Oxidation and rusting of copper alloys increase DC loop resistance and unbalance resistance, resulting in increased insertion loss and return loss. Nickel plating on the surface of phosphor bronze can solve the problem of data loss or even transmission link failure due to rusting.
Finished patch cords in the patch panels jumper widespread adjustment of information points or re-topology patch panel due to frequent unplugging of patch cords, the “gold pin” will produce a certain amount of wear and tear. To achieve 15 years of design use requirements. Wear-resistant materials must be used to coat the “gold pin” to play the role of wear-resistant. Patch panels manufacturers generally use gold to electroplate the “gold pin to accomplish the wear-resistance effect.” The information jack plated with gold can meet the industry requirement that the information jack must be able to withstand more than 750 times of plugging and unplugging tests.
The skeleton of the patch panel is cold-rolled steel, which has good mechanical resistance and can resist all kinds of extrusion and impact. Not easy to deformation, and cold-rolled steel is not easy to rust and can meet the network patch panels for at least 15 years of user needs.
The back end of the patch panels is the IDC hitting column and back cover. The back cover is made of ABS plastic. The body is labeled with TIA 568A/B, two types of wire order, and the color code of the wire core.
The shell of the IDC punching post is PC plastic. PC plastic is also known as polycarbonate plastic. It is an excellent elasticity and impact resistance of the plastic; after being extruded, deformation can quickly recover the original shape.
Therefore, the use of PC plastic IDC hitting column in the impact of the hitting tool not only will not produce damage but also quickly restore the original position and clip the cable so that the line does not fall off.
The core of the wire hitting post is a nickel-plated phosphor bronze pinch pin. The upper part is used to clamp and break through the core skin to make contact with the conductors in the core and transmit the signal to the circuit board’s line. The lower part is soldered to the circuit board.
Inside the wiring, the frame is the circuit board; generally, in a one-piece patch panel, six information jacks share a circuit board, modular patch panels, and each information jack has a circuit board. The circuit boards of different patch panels are generally distinct because different brands of integrated cabling manufacturers have differences in the stranding distance of their cables. The circuit board of a patch panels is designed according to the structural scheme of the cable. Therefore, the circuit boards of patch panels generally differ from manufacturer to manufacturer.

How many types of a Network Patch Panels?
Since AT&T invented the 110 port patch panels in 1989, more and more types of network patch panels have emerged. 24 port patch panel, modular patch panel, angled patch panels， electronic patch panel, and other network patch panels products. The transmission performance of various types of patch panels can be divided into super category five patch panels, category 6 patch panels, super category 6 patch panels, etc.; the presence or absence of a shielding layer can be divided into non-shielded patch panels and shielded network patch panels.
The standard network patch panel on the market mainly includes 24 port patch panels, modular patch panels, angled patch panels, electronic patch panels, etc.. Among them, the integrated patch panels is the most common.
24 Port Network Patch Panel
24 port network patch panel from the appearance of the 24 RJ45 jacks encapsulated in the patch panels skeleton, connected into one. Its internal structure is generally six RJ45 jacks that share a circuit board.
The advantage of this kind of patch panel is that the production process is mature and consumes low; therefore, compared to other types of patch panels, the price of the integrated patch panel is expected. And the construction process is simple, and the builder only needs to install the cable to the patch panels. Therefore, it is loved by the comprehensive wiring construction personnel.
However, the 24 port patch panel is a one-piece package and adopts the structure of multiple information points sharing one circuit board. Therefore, replacing a port isn’t easy to replace when port is damaged. Therefore, once the port is damaged, it generally can only abandon the port.
Moreover, the construction personnel can only buy the 24-port patch panels that has been pre-installed by the manufacturer and cannot delete the ports or mix other types of ports according to their actual needs.
It is more solidified. And in terms of transmission performance, six information jacks sharing a board will increase the mutual interference between different information points. Make access to the system of patch panel.
Modular Patch Panel
For the integrated network, patch panel damage can not be replaced, port replacement is not flexible, and other characteristics—comprehensive wiring manufacturers after a lot of research and improvement. The modular patch panels was introduced. As the name implies, the modular patch panels is the network patch panels of each RJ45 information jack independent package and then assembled into the patch panel skeleton.
The advantage of using this structure is that each information jack independently uses a circuit board and uses a PC rubber for each information jack package in a separate space. From the perspective of transmission performance, each information jack of the modular patch panel is independent of each other, and the interference between the information systems connected to the modular patch panel is negligible—enhanced access to the system’s ability to resist external interference.
In addition, due to the independent structure of the scheme, users can use a modular patch panel, according to the actual design requirements, the RJ45 port deletion or other types of RJ45 interface, or even RJ11 interface.
Therefore, the modular patch panel is more flexible and compatible than the all-in-one patch panels and can reduce unnecessary waste in wiring construction and save wiring space.
In addition, due to the modular freestanding design, each RJ45 information module on the patch panel can be removed for construction and reinstallation. For the construction of patch panels installed in wall-mounted or embedded cabinets, the construction personnel must use the “human ladder” to carry out wiring construction due to its high installation environment, which is a relatively narrow construction environment.
Although the construction of a 24 port network patch panels can be carried out by reversing the patch panel, the space available for operation is small, and it is easy to cause the failure of wiring, which is not easy to construct. Using a modular patch panels for wiring, constructors can take out the information module and install it back into the patch panels after completing the construction on the ground. Therefore, the modular patch panel can meet the structure of a more narrow environment.
The disadvantage of a modular patch panel is that it requires more production materials due to the use of a freestanding structure and requires a more refined production process because each information jack uses a circuit board independently. This is why the price of modular patch panels is higher than that of all-in-one patch panels. In addition, because the independent design of the modular patch panel brings a smaller line sequence labeling paper, the modular patch panel is more complex than the 24 port patch panels for personnel who must refer to the labeling paper in order to play the line construction. In addition, because the modular patch panels can be disassembled, very few construction personnel will be second best.
Early 24 port network patch panel and modular patch panels are linear patch panels. Network patch panels must be used with horizontal cable management frames to manage patch cords better and beautify the wiring environment. However, the design solution of the patch panels plus cable management frame needs to occupy 2U of space in the cabinet because the network cabinet is generally 42U.
When the network cabinet space is sufficient, it is feasible to use the network wiring frame and cable management frame structure solution. However, when the cabinet space is limited, using structural solutions will take up too many cabinet resources. The shortcomings of this structure solution are increasingly evident in today’s high-speed development of the Internet and the increasing shortage of cabinet resources.
Angled Patch Panel
The angled patch panel divides the information jacks originally arranged in the same straight line into two from the middle, making a fracture-type treatment. The middle connection is equipped with a rotating screw so that users can rotate the wiring frame on the Z-axis from 0 to 120° according to their needs. Using this angled patch panel can isolate the cable part of the crosstalk and automatically divide the cable into two parts and step cable management. The user only needs to wire according to the length of your information jack and patch the cable jumper to the next RJ45 port without needing a cable management frame. This saves 1U of cabinet space.
The disadvantage of angled patch panels is that their structure is more complex than modular patch panels and all-in-one patch panels. As a result, the production process is more complex and requires more production materials. As a result, its price is higher.

Electronic Patch Panel
Traditional patch panels are installed with identification strips at the ports to facilitate network administrators in managing different information points. However, these identification strips are easy to lose, and the identification code will be blurred with increased use time. The identification function will be lost after a certain period. This brings a lot of trouble to the later maintenance and management of the network.
Therefore, in recent years, a new type of patch panel- the electronic patch panels began to take off. This network patch panel uses an electronic liquid crystal display instead of the traditional paper marking strip. The patch panels will display the corresponding port number as soon as it is powered on. It is convenient for the follow-up personnel to manage the network. Moreover, part of the electronic patch panel can also count the real-time POE energy consumption and send the corresponding port data to the network manager’s equipment terminal via wireless LAN, which is convenient for the manager’s management.
The disadvantage of electronic patch panels is that the introduction of electronic LCD increases the difficulty of the production process of the network patch panel. It increases the production cost. At the same time, the use of an electronic patch panel requires a power supply to the display, which increases the loss of power on the one hand, and increases the impact of external crosstalk on the cable on the other. In addition, it may also mislead the network manager when the data collection and display of electronic patch panel report errors.
Cat 5e Patch Panel
Cat 5e patch panel is used for the cat 5e cabling system. With a transmission bandwidth of 155MHz and up to 1000Mbps Ethernet, it had dominated the integrated cabling market for a long time. Still, with the development of the Internet and the increasing demand for large bandwidth networks, its market share has slowly decreased.
Cat 6 Patch Panel
The cat 6 patch panel is suitable for cat 6 cabling systems. With a transmission bandwidth of 250 MHz, it can stably transmit 1 Gbps Ethernet networks and meets the 2018 publication Information Technology. General cabling for user building complexes (ISO/IEC 11801:2018) for building horizontal links using cat 6 and cat 6+ cabling systems.
Cat 6e Network Patch Panel
Cat 6e patch panel is used for the cat 6e cabling system. With a transmission bandwidth of 500MHz, it can stably transmit a 10Gbps Ethernet network and is suitable for future wiring use in intelligent buildings.
Straight-Through Network Patch Panel
The straight-through network patch panel is a patch panel with dual RJ45 jacks that can be used by crimping the cable directly to the crystal head and then plugging it in directly. The cable installed on one end of the patch panel is a single twisted pair cable. In the actual construction, directly connected to the crystal head to use. Single-stranded twisted-pair cable to the port of the pull is very large, installed on the single-stranded twisted-pair cable crystal head and patch panel information jack in the gold pin is very easy because of the single-stranded twisted-pair cable pull and lead to poor link contact or even lead to port damage; resulting in cable link does not work.
Optical Fiber Distribution Frame
The optical fiber distribution frame is generally a plastic fiber installed on a patch panel. It is used together with the cable with fiber optics. It can achieve the purpose of the line found in one second. However, according to the Engineering Design Specification for Integrated Cabling Systems (GB 50311), the service life of a permanent link is generally 15 years. The quality of cabling links that meet industry standards and are constructed according to specifications will not have quality problems during everyday use. Therefore, this design is a bit impractical.

How to test the Network Patch Panel?
Wiring frame will generally be plugging and unplugging test for information jacks, and the industry requires typically information jacks can pass at least 750 times of plugging and unplugging test. For the transmission performance, the patch panel is generally used with the cable and cannot be used alone.
Therefore, there is no single test for the patch panel. It is generally tested for transmission performance by permanent link test or channel test. The test equipment used are FLUKE test equipment, etc.
In addition, due to the increase in environmental awareness in recent years. The plastic materials used in the network patch panel must pass ROHS or REACH and other environmental testing requirements of the EU.

How to use Patch Panel in Networking ?
A network patch panel typically has 24 interfaces. You can use a network patch panel to manage the information points on one floor or several floors according to the actual information points when you are budgeting for the project.
Second, a 24-port network patch panel is generally paired with a 19-inch-long, 1U-high 12-ring horizontal cable manager for use. Typically, a cable management ring installs two patch cords arranged in front and behind. It is generally not recommended to install more than two jumpers to avoid the lack of space for the installation of jumper formation extrusion. Affect the link transmission performance.
Third, it is recommended that you follow the design scheme of unshielded cabling products with unshielded cabling products and shielded cabling products with protected cabling products. Suppose you use a shielded patch panel design scheme plus unshielded cables and patch cords. Then, the covered patch panel does not play the role of shielding but will waste the shielding function of the shielded patch panel. Shielded links using a non-shielded patch panel is not only a waste of the link shielding function, and even because the shielding grounding is not complete. You are resulting in the cable by the shielding layer induction current or even indirect lightning strikes.
