Fiber Optic Cable Core-How Much Do You Know About It?

For anyone who wants to know fiber optic cable core, it’s a must to know the structure of a fiber optic cable. For a fiber optic cable, it consists of three basic parts: the core, the fiber optic cable core cladding, and the coating layer outside the cladding.

What Is Fiber Optic Cable Core?

A conventional fiber optic cable core is a glass or plastic made cylinder running along the fiber’s length. This part is designed for light transmission. Therefore, the larger the core, the more light that will be transmitted into the fiber. As we mentioned before, the core is surrounded by the cladding layer to provide a lower fiber optic cable core index of refraction. So more light can be transmitted into the fiber.

Fiber Optic Cable Core Types

According to different standards or features, the fiber optic cable can be grouped into different types. For example, classified by connectors, we can get LC fiber, SC fiber, etc; classified by transmission mode, we can get multimode fiber and single mode fiber. Likewise, with different features, the fiber optic cable core can also be divided into different types.

Fiber Optic Cable Core Material

According to the material, plastic and glass cores can be found. When the core is made from pure glass, the cladding is from the less pure glass. Glass type has the lowest attenuation over long distances but comes at the highest cost. As for the plastic core type, it is not as clear as glass one but is more flexible and easier to handle. Moreover, the plastic type is more affordable for us.

Fiber Optic Cable Core Size

Based on sizes, the fiber optic core can be grouped into quite a lot of types. Basically, the most common core sizes are 9 µm in diameter (single mode), 50 µm in diameter (multimode), 62.5 µm in diameter (multimode). For your better understanding, please look at Figure 2 as below. It’s a comparison of the three common sizes when they are inside the same cladding layer diameters (125 µm).

Fiber Optic Cable Core Numbers

Featured by how many cores in fiber optic cables, two kinds of cable cores can be arranged: the single core and the multicore. The single core type refers to the fiber cable that consists of a core and a cladding layer, which is the most common type in the market. However, the multicore fiber optic cable means that in the same cladding layer, there are more than one core in it. The commonly used cables are four, six, eight, twelve, twenty-four cores.

Conclusion

Based on the knowledge about fiber optic cables, we have a basic idea about its structure and functions each part has played, especially the fiber optic cable core. After knowing what the core is, we also introduce the types of the fiber optic core. Classified by different features, such as core material and size, we can get different types. Hoping after this article, you will have a much clearer vision about the fiber optic core.

2x 24-Port Patch Panels or 1x 48-Port Patch Panel?

Patch panel is a passive networking device that bundles multiple ports together. It is a simple and organized solution frequently used in connecting different computers, telecommunications devices, and external hardware to others. Though wireless internet connections is becoming more popular, the use of a patch panel can actually optimize the internet speed especially in data center. Using a patch panel to arrange the circuit, users just need to plug or unplug the proper patch cords. According to the numbers of ports, patch panels can be divided into 12-port patch panel, 24-port patch panel and 48-port patch panel. They are designed in accordance with specific cable type, such as Cat5e, Cat6, Cat6a and Cat7 cables.

What Are Patch Panel Ports?

The port, as a part of patch panel, is the connection point that allows data to enter or leave the panel. Each port is connected via an ethernet or a fiber cable, then sends signal to an outgoing port location. On market, most patch panels are equipped with 24 ports or 48 ports. Selection of different patch panels should be based on one’s actual need. In addition, the port number is limited by the room for placing but not other factors. For example, the requirement of port number must be confirmed when someone designs a LAN network, so as to use the suitable panel size.

24-Port Patch Panel

FS.COM produced the product high quality 24 Ports Cat6 Shielded feed-through patch panel. It is made for optimum performance with black color and materials of SPCC+ABS plastics. The design of high density 19-inch 1RU panel can make it convenient for being mounted in any standard 19-inch rack or cabinet, accommodates top, bottom or side cable entry. Viewed in another aspect, the high density format also can save valuable space in the rack. Here is a video you can see 24-port patch panel clearly.

48-Port Patch Panel

The 48 ports blank keystone/multimedia patch panel, manufactured by FS.COM, is made of SPCC CRS material with advantages of molding in one, sturdy and durable. The design of 48 ports can accommodate all keystone jacks, including RJ45 Ethernet, HDMI audio/video, voice and USB applications. In addition, the high density 19in wide, 1U High, panel design will save valuable space in the rack.

48 port panels

2x 24-Port Patch Panels or 1x 48-Port Patch Panel?

Both 24-port patch panels and 48-port patch panel can serve ethernet networks, fast or gigabit Ethernet networks. However, due to their individual designs and materials, the price varies. This is a big factor when people buy patch panels. At FS.COM, the price discrepancy between 24-port patch panel and 48-port is slight. As a result, buying two 24-port patch panels is definitely more expensive than buying one 48-port product. Besides, the space for installation should be another consideration. Thus, considered in these two ways, chose the 48-port patch panel is better. And we must realize that network is always developing, so why not staying up to date and ahead of the curve by utilizing the benefits of 48-port patch panel rather than trying to keep up with the pace.

Conclusion

The two types patch panels are the cost-effective and easy-to-use cabling solution for modern data center. Choose 2x 24-port patch panels or 1x 48 port should based on your own need. FS.COM is your source for high quality patch panels covering different ports including 12-port, 24-port, and 48-port options.
